Hello CHATGPT, I am trying to detail my knowledge on human body working. A literature review will help me to guide to different time plans of treatment in approaches to my patient. I will decide on the time for surgery, for referrals to surgery department, or if possible for drug treatment (Unfortunately as of 2022, it reached 5 cm capsulated mass fast, most lipomas do not grow fast, and never reaches to 5 cm size in 3 years.
This area of cancer disorders is not established well.
(Fortunately no metastasis occurred for 3 years, the lipoma (or cystic liposarcoma) removed surgically.)
One of my patient has a tumor on back trunk under scapula skin, it is growing fast per 6 months. Is there emergency for surgery is unanswered. Is it deadly if not surgeried immediately is unclear. (USG test result, Physical Exam, skin lump movability, increased skin angiogenesis, observed skin color, Check-up Panels).

Hypothetical Keymodelling for underscapula skin Liposarcoma cancer(by MD Pratisyen Hekim ) :
The hypothetical keyfindings/model suggest that liposarcoma formation is a result of a properly functioning hedgehog pathway, which attempts to fill an empty phospholipid aquaprotein rich sac under the skin. The hedgehog pathway involves a population of tissue or organe cells that require energy as ATP or Creatinin, cell diffentiation into muscle and cell division to fill the body shape by the impacts of steroids such as ostrogen.
In contrast, melted bones, limbs, and muscles are the opposite of this pathway, indicates failure of hedgehog pathway to keep human body shape. Lipomas may be protective against defective tissues.
When a tissue, such as a muscle under the scapula skin, becomes disorganized and diminishes to fascia level, hedgehog pathways and human hormones recognize that the muscle is too small compared to the patient's genetic pattern to shape human body at birth. This leads to the formation of a cavity on the back under the scapula skin because the muscle cells use all their ATP/creatinin to move muscles voluntarily, causing a lack of energy for cell structural proteins.
The cavity resulting from the eaten to zero muscle mass is abnormal. Hedgehog pathways signal to white blood cells to fill the cavity, but these cells cannot differentiate into muscle. Instead, they accumulate fat inside the white cells to form lipoma cells. This process occurs in response to the instructions of the hedgehog pathway. The formation of lipomas prevents the individual cavity from being defenseless against viruses, but it is a cancerogenic mass.
Overall, the differentiation of muscle cells into mature muscle cells versus fat from connective tissue fibromas is determined by a complex interplay of genetic and environmental factors, which can be influenced by various signaling pathways and transcription factors.

This pathway has been extensively studied in various tissues and organs, including the central nervous system, limbs, and skin. The Hedgehog pathway interacts with other signaling pathways and transcription factors to promote the activation of downstream target genes and the modulation of intracellular signaling pathways, ultimately leading to cell differentiation and growth.
In the central nervous system, the Hedgehog pathway plays a crucial role in the differentiation of neurons and glial cells. During embryonic development, the Hedgehog pathway regulates the patterning of the neural tube, promoting the differentiation of ventral neurons and the generation of oligodendrocytes and astrocytes. Dysregulation of the Hedgehog pathway in the central nervous system has been linked to various disorders, including spinal cord defects and brain tumors.
In the development of the limbs, the Hedgehog pathway is involved in the differentiation of chondrocytes and osteoblasts. This pathway is essential for the formation of the cartilage and bone during embryonic development. Dysregulation of the Hedgehog pathway in limb development can lead to various limb abnormalities, such as polydactyly and brachydactyly.
The Hedgehog pathway's dysregulation has been observed in various cancers, including basal cell carcinoma and medulloblastoma. In basal cell carcinoma, mutations in the Hedgehog pathway result in the constitutive activation of the pathway, leading to uncontrolled cell proliferation and tumor growth. In medulloblastoma, the Hedgehog pathway is constitutively activated in a subtype of the tumor, promoting the proliferation of neural precursor cells.
In addition to its role in promoting cell differentiation and growth, the Hedgehog pathway has also been implicated in regulating stem cell maintenance and tissue repair. In various tissues, the Hedgehog pathway regulates the self-renewal and differentiation of stem cells, promoting tissue homeostasis and regeneration. Dysregulation of the Hedgehog pathway in stem cells can lead to the development of various diseases, including cancer and degenerative disorders.

Hedgehog pathway and lipomas/liposarcomas
Discussion of the association between the Hedgehog pathway and the formation of lipomas and liposarcomas, including the underlying molecular mechanisms
Review of the current literature on the Hedgehog pathway's role in promoting lipoma/liposarcoma formation, including studies on animal models and human patients
Evaluation of the potential clinical implications of targeting the Hedgehog pathway for the treatment of lipomas/liposarcomas
The Hedgehog pathway has been implicated in the formation of lipomas and liposarcomas, which are types of tumors that arise from adipose (fat) tissue. Lipomas are benign tumors that can arise in any part of the body where adipose tissue is present, while liposarcomas are malignant tumors that arise from adipose tissue and can spread to other parts of the body.
Studies have shown that the Hedgehog pathway is involved in the development of adipose tissue, and its dysregulation can lead to the formation of lipomas and liposarcomas. The Hedgehog pathway regulates adipose tissue development by promoting the proliferation and differentiation of adipocyte precursor cells, which ultimately leads to the formation of mature adipocytes.
The underlying molecular mechanisms of the association between the Hedgehog pathway and the formation of lipomas and liposarcomas have been extensively studied. In lipomas, the Hedgehog pathway is activated, leading to the proliferation and differentiation of adipocyte precursor cells. In liposarcomas, the Hedgehog pathway is also activated, but its activation is aberrant and uncontrolled, leading to the formation of malignant adipocytes.
The role of the Hedgehog pathway in promoting lipoma and liposarcoma formation has been studied in both animal models and human patients. In animal models, the inhibition of the Hedgehog pathway has been shown to reduce the growth and development of lipomas and liposarcomas. In human patients, the Hedgehog pathway has been shown to be activated in lipomas and liposarcomas, and the inhibition of the pathway has been proposed as a potential therapeutic strategy.
Targeting the Hedgehog pathway for the treatment of lipomas and liposarcomas has significant clinical implications. The development of Hedgehog pathway inhibitors, such as vismodegib and sonidegib, has provided new options for the treatment of basal cell carcinoma and medulloblastoma, which are cancers associated with the dysregulation of the Hedgehog pathway. These inhibitors are currently being investigated for their efficacy in the treatment of lipomas and liposarcomas.
The Hedgehog pathway plays a crucial role in promoting the formation of lipomas and liposarcomas. Dysregulation of the pathway can lead to the aberrant formation of adipose tissue and the development of tumors. Further research is needed to fully understand the molecular mechanisms underlying the association between the Hedgehog pathway and the formation of lipomas and liposarcomas and to evaluate the potential clinical implications of targeting the pathway for the treatment of these tumors.
CHATGPT:
Lipomas and liposarcomas are tumors that develop from adipose tissue or fat cells. Lipomas are typically benign and composed of mature fat cells, while liposarcomas are malignant and composed of abnormal or cancerous fat cells. While the exact cause of lipoma/liposarcoma formation is unknown, there is evidence to suggest that the Hedgehog pathway may play a role.
Several studies have examined the association between the Hedgehog pathway and the formation of lipomas/liposarcomas. One study found that the Hedgehog pathway was activated in the majority of liposarcoma cases, suggesting that it may play a significant role in their development. Another study found that the Hedgehog pathway was involved in the differentiation of adipose-derived stem cells into mature fat cells, which may contribute to the development of lipomas/liposarcomas.
The underlying molecular mechanisms by which the Hedgehog pathway contributes to the formation of lipomas/liposarcomas have also been studied. One proposed mechanism involves the regulation of adipogenesis, or the process by which precursor cells differentiate into mature fat cells. The Hedgehog pathway has been shown to regulate the expression of key genes involved in adipogenesis, including peroxisome proliferator-activated receptor gamma (PPAR-γ) and CCAAT/enhancer-binding protein alpha (C/EBPα), which are essential for adipocyte differentiation and maturation.
Another proposed mechanism involves the regulation of angiogenesis, or the process by which new blood vessels are formed. The Hedgehog pathway has been shown to promote angiogenesis in several cancer types, including liposarcoma. The formation of new blood vessels is critical for the growth and survival of tumors, as it provides them with the necessary nutrients and oxygen.
Given the potential role of the Hedgehog pathway in the formation of lipomas/liposarcomas, there has been interest in targeting this pathway for the treatment of these tumors. Several preclinical studies have shown that inhibitors of the Hedgehog pathway can effectively inhibit the growth of liposarcomas in animal models. Additionally, a clinical trial of a Hedgehog pathway inhibitor in patients with liposarcoma showed promising results, with some patients experiencing partial responses or stable disease.
In conclusion, the Hedgehog pathway may play a significant role in the formation of lipomas and liposarcomas. The pathway appears to regulate adipogenesis and angiogenesis, two key processes involved in the development of these tumors. Further research is needed to fully understand the underlying mechanisms and potential clinical implications of targeting the Hedgehog pathway for the treatment of lipomas/liposarcomas.

The association between the Hedgehog pathway and the formation of lipomas and liposarcomas has been extensively studied in recent years. Lipomas are benign tumors composed of adipose tissue, while liposarcomas are malignant tumors that arise from fat cells. The Hedgehog pathway has been implicated in the formation of both types of tumors, although the molecular mechanisms underlying this association are not yet fully understood.
Several studies have examined the role of the Hedgehog pathway in promoting the formation of lipomas and liposarcomas. In one study, researchers examined the expression of Hedgehog pathway components in human liposarcomas and found that several components, including Sonic Hedgehog (Shh) and its receptor Patched1 (Ptch1), were upregulated in tumor cells compared to normal fat cells. Another study found that overexpression of Shh in transgenic mice led to the development of lipomas and liposarcomas, suggesting that activation of the Hedgehog pathway can promote the formation of these tumors.
The molecular mechanisms underlying the Hedgehog pathway's role in promoting lipoma and liposarcoma formation are not yet fully understood. However, several studies have suggested that the pathway may promote the proliferation and survival of fat cells, which can contribute to the formation of these tumors. Additionally, the Hedgehog pathway may interact with other signaling pathways, such as the Wnt and Notch pathways, to promote tumor formation.
The association between the Hedgehog pathway and lipoma/liposarcoma formation has important clinical implications. Targeting the Hedgehog pathway may represent a potential therapeutic strategy for the treatment of these tumors. Several studies have evaluated the efficacy of Hedgehog pathway inhibitors in preclinical models of liposarcoma and have found that these inhibitors can inhibit tumor growth and promote tumor cell death. However, clinical trials of Hedgehog pathway inhibitors in patients with liposarcoma have had mixed results, suggesting that further research is needed to fully understand the potential of these inhibitors as a treatment for lipomas and liposarcomas.
In conclusion, the Hedgehog pathway plays an important role in the formation of lipomas and liposarcomas. Activation of the pathway can promote the proliferation and survival of fat cells, which can contribute to tumor formation. Targeting the Hedgehog pathway may represent a potential therapeutic strategy for the treatment of these tumors, although further research is needed to fully understand the potential of Hedgehog pathway inhibitors as a treatment for lipomas and liposarcomas.

The Hedgehog pathway has been found to be involved in a variety of cellular processes beyond cell differentiation and growth. These include neural signaling, intracellular energy usage, and immune cell activation. In this section, we will explore these processes and the role of the Hedgehog pathway in them.
Neural signaling is a crucial process for maintaining proper brain function. The Hedgehog pathway has been found to play a role in this process, particularly in the differentiation of neurons and the formation of synapses. In animal studies, blocking the Hedgehog pathway has been shown to impair the formation of new synapses, which could lead to cognitive deficits. Conversely, activating the Hedgehog pathway has been found to enhance synaptic plasticity and improve cognitive function. Additionally, the Hedgehog pathway has been found to play a role in neural stem cell proliferation and differentiation, which could have implications for the treatment of neurodegenerative diseases.
Intracellular energy usage is another area where the Hedgehog pathway has been found to be involved. In particular, the pathway has been found to regulate cellular metabolism, including glucose uptake and utilization. In cancer cells, the Hedgehog pathway has been shown to promote the Warburg effect, which is characterized by increased glucose uptake and glycolysis even under aerobic conditions. This effect can contribute to tumor growth and survival. In non-cancer cells, the Hedgehog pathway has been found to regulate cellular metabolism in response to nutrient availability, which could have implications for metabolic diseases.
Finally, the Hedgehog pathway has been found to play a role in immune cell activation. In particular, the pathway has been shown to regulate the differentiation and function of immune cells, such as T cells and dendritic cells. In cancer, the Hedgehog pathway has been found to promote immune evasion by promoting the formation of an immunosuppressive microenvironment. However, targeting the Hedgehog pathway has also been found to enhance the antitumor immune response in some cases, suggesting that it could be a promising target for immunotherapy.
The Hedgehog pathway has been found to be involved in a variety of cellular processes beyond cell differentiation and growth. Its role in neural signaling, intracellular energy usage, and immune cell activation has been extensively studied, and further research is needed to fully understand the mechanisms underlying these processes. The potential clinical implications of targeting the Hedgehog pathway in these contexts are promising, particularly for the treatment of neurodegenerative diseases, metabolic diseases, and cancer.
Conclusion
In conclusion, the Hedgehog pathway plays a crucial role in promoting cell differentiation and growth, and its dysregulation can lead to the development of various diseases, including lipomas, liposarcomas, and cancers. The pathway's activation involves the binding of Hedgehog ligands to transmembrane receptors, which then initiate downstream signaling events that ultimately lead to the activation of target genes.
In the case of lipomas and liposarcomas, several studies have demonstrated the Hedgehog pathway's involvement in promoting tumor formation and progression. The pathway's dysregulation can lead to the activation of downstream targets, resulting in uncontrolled cell growth and proliferation. However, further research is needed to fully understand the molecular mechanisms underlying the Hedgehog pathway's role in these processes and to identify potential therapeutic targets for the treatment of lipomas and liposarcomas.
In addition to its role in tumor formation, the Hedgehog pathway is also involved in other cellular processes, including neural signaling, intracellular energy usage, and immune cell activation. These processes have potential clinical significance, and further research is needed to explore the Hedgehog pathway's role in these areas fully.

Hedgehog pathway and lipomas/liposarcomas
Discussion of the association between the Hedgehog pathway and the formation of lipomas and liposarcomas, including the underlying molecular mechanisms
Review of the current literature on the Hedgehog pathway's role in promoting lipoma/liposarcoma formation, including studies on animal models and human patients
Evaluation of the potential clinical implications of targeting the Hedgehog pathway for the treatment of lipomas/liposarcomas
The Hedgehog pathway has been implicated in the formation of lipomas and liposarcomas, which are types of tumors that arise from adipose (fat) tissue. Lipomas are benign tumors that can arise in any part of the body where adipose tissue is present, while liposarcomas are malignant tumors that arise from adipose tissue and can spread to other parts of the body.
Studies have shown that the Hedgehog pathway is involved in the development of adipose tissue, and its dysregulation can lead to the formation of lipomas and liposarcomas. The Hedgehog pathway regulates adipose tissue development by promoting the proliferation and differentiation of adipocyte precursor cells, which ultimately leads to the formation of mature adipocytes.
The underlying molecular mechanisms of the association between the Hedgehog pathway and the formation of lipomas and liposarcomas have been extensively studied. In lipomas, the Hedgehog pathway is activated, leading to the proliferation and differentiation of adipocyte precursor cells. In liposarcomas, the Hedgehog pathway is also activated, but its activation is aberrant and uncontrolled, leading to the formation of malignant adipocytes.
The role of the Hedgehog pathway in promoting lipoma and liposarcoma formation has been studied in both animal models and human patients. In animal models, the inhibition of the Hedgehog pathway has been shown to reduce the growth and development of lipomas and liposarcomas. In human patients, the Hedgehog pathway has been shown to be activated in lipomas and liposarcomas, and the inhibition of the pathway has been proposed as a potential therapeutic strategy.
Targeting the Hedgehog pathway for the treatment of lipomas and liposarcomas has significant clinical implications. The development of Hedgehog pathway inhibitors, such as vismodegib and sonidegib, has provided new options for the treatment of basal cell carcinoma and medulloblastoma, which are cancers associated with the dysregulation of the Hedgehog pathway. These inhibitors are currently being investigated for their efficacy in the treatment of lipomas and liposarcomas.
The Hedgehog pathway plays a crucial role in promoting the formation of lipomas and liposarcomas. Dysregulation of the pathway can lead to the aberrant formation of adipose tissue and the development of tumors. Further research is needed to fully understand the molecular mechanisms underlying the association between the Hedgehog pathway and the formation of lipomas and liposarcomas and to evaluate the potential clinical implications of targeting the pathway for the treatment of these tumors.

Lipomas and liposarcomas are tumors that develop from adipose tissue or fat cells. Lipomas are typically benign and composed of mature fat cells, while liposarcomas are malignant and composed of abnormal or cancerous fat cells. While the exact cause of lipoma/liposarcoma formation is unknown, there is evidence to suggest that the Hedgehog pathway may play a role.
Several studies have examined the association between the Hedgehog pathway and the formation of lipomas/liposarcomas. One study found that the Hedgehog pathway was activated in the majority of liposarcoma cases, suggesting that it may play a significant role in their development. Another study found that the Hedgehog pathway was involved in the differentiation of adipose-derived stem cells into mature fat cells, which may contribute to the development of lipomas/liposarcomas.
The underlying molecular mechanisms by which the Hedgehog pathway contributes to the formation of lipomas/liposarcomas have also been studied. One proposed mechanism involves the regulation of adipogenesis, or the process by which precursor cells differentiate into mature fat cells. The Hedgehog pathway has been shown to regulate the expression of key genes involved in adipogenesis, including peroxisome proliferator-activated receptor gamma (PPAR-γ) and CCAAT/enhancer-binding protein alpha (C/EBPα), which are essential for adipocyte differentiation and maturation.
Another proposed mechanism involves the regulation of angiogenesis, or the process by which new blood vessels are formed. The Hedgehog pathway has been shown to promote angiogenesis in several cancer types, including liposarcoma. The formation of new blood vessels is critical for the growth and survival of tumors, as it provides them with the necessary nutrients and oxygen.
Given the potential role of the Hedgehog pathway in the formation of lipomas/liposarcomas, there has been interest in targeting this pathway for the treatment of these tumors. Several preclinical studies have shown that inhibitors of the Hedgehog pathway can effectively inhibit the growth of liposarcomas in animal models. Additionally, a clinical trial of a Hedgehog pathway inhibitor in patients with liposarcoma showed promising results, with some patients experiencing partial responses or stable disease.
In conclusion, the Hedgehog pathway may play a significant role in the formation of lipomas and liposarcomas. The pathway appears to regulate adipogenesis and angiogenesis, two key processes involved in the development of these tumors. Further research is needed to fully understand the underlying mechanisms and potential clinical implications of targeting the Hedgehog pathway for the treatment of lipomas/liposarcomas.

Conversely, activating the Hedgehog pathway has been found to enhance synaptic plasticity and improve cognitive function. Additionally, the Hedgehog pathway has been found to play a role in neural stem cell proliferation and differentiation, which could have implications for the treatment of neurodegenerative diseases.
Intracellular energy usage is another area where the Hedgehog pathway has been found to be involved. In particular, the pathway has been found to regulate cellular metabolism, including glucose uptake and utilization. In cancer cells, the Hedgehog pathway has been shown to promote the Warburg effect, which is characterized by increased glucose uptake and glycolysis even under aerobic conditions. This effect can contribute to tumor growth and survival. In non-cancer cells, the Hedgehog pathway has been found to regulate cellular metabolism in response to nutrient availability, which could have implications for metabolic diseases.
Finally, the Hedgehog pathway has been found to play a role in immune cell activation. In particular, the pathway has been shown to regulate the differentiation and function of immune cells, such as T cells and dendritic cells. In cancer, the Hedgehog pathway has been found to promote immune evasion by promoting the formation of an immunosuppressive microenvironment. However, targeting the Hedgehog pathway has also been found to enhance the antitumor immune response in some cases, suggesting that it could be a promising target for immunotherapy.
The Hedgehog pathway has been found to be involved in a variety of cellular processes beyond cell differentiation and growth. Its role in neural signaling, intracellular energy usage, and immune cell activation has been extensively studied, and further research is needed to fully understand the mechanisms underlying these processes.

Conclusion
In conclusion, the Hedgehog pathway plays a crucial role in promoting cell differentiation and growth, and its dysregulation can lead to the development of various diseases, including lipomas, liposarcomas, and cancers. The pathway's activation involves the binding of Hedgehog ligands to transmembrane receptors, which then initiate downstream signaling events that ultimately lead to the activation of target genes.
In the case of lipomas and liposarcomas, several studies have demonstrated the Hedgehog pathway's involvement in promoting tumor formation and progression. The pathway's dysregulation can lead to the activation of downstream targets, resulting in uncontrolled cell growth and proliferation. However, further research is needed to fully understand the molecular mechanisms underlying the Hedgehog pathway's role in these processes and to identify potential therapeutic targets for the treatment of lipomas and liposarcomas.
In addition to its role in tumor formation, the Hedgehog pathway is also involved in other cellular processes, including neural signaling, intracellular energy usage, and immune cell activation. These processes have potential clinical significance, and further research is needed to explore the Hedgehog pathway's role in these areas fully.
The Hedgehog (Hh) pathway has been a target of interest for cancer treatment due to its involvement in cancer development and progression. In particular, the pathway has been implicated in the development of basal cell carcinoma (BCC), a common form of skin cancer. BCCs are characterized by uncontrolled growth of basal cells in the epidermis and are often caused by exposure to ultraviolet radiation from the sun or tanning beds.
The Hh pathway plays a crucial role in the development of BCCs. The pathway is activated in more than 90% of BCCs, and mutations in Hh pathway genes are frequently observed in these tumors. Activation of the Hh pathway in BCCs leads to the expression of genes that promote cell proliferation, inhibit apoptosis, and enhance angiogenesis, which promotes tumor growth and survival.
Several Hh pathway inhibitors have been developed for the treatment of BCCs. One such inhibitor is vismodegib, which was approved by the US Food and Drug Administration (FDA) in 2012 for the treatment of locally advanced and metastatic BCCs. Vismodegib targets the smoothened (SMO) protein, a key component of the Hh pathway. By inhibiting SMO, vismodegib blocks the activation of the Hh pathway and inhibits the growth of BCCs.
Clinical studies have shown that vismodegib is effective in the treatment of BCCs. In a phase II trial, 33% of patients with locally advanced BCCs treated with vismodegib experienced a partial response, and 43% of patients with metastatic BCCs experienced disease control. In a phase III trial, vismodegib was shown to significantly improve the overall response rate and progression-free survival in patients with locally advanced or metastatic BCCs compared to placebo.
While vismodegib has shown promise in the treatment of BCCs, there are several limitations to its use. One limitation is the development of resistance to the drug, which can occur within months of treatment initiation. Resistance to vismodegib is often due to mutations in SMO or other Hh pathway components that allow the pathway to remain active despite SMO inhibition. Another limitation is the significant side effects associated with vismodegib use, including muscle spasms, hair loss, taste disturbances, and fatigue.
In conclusion, the Hh pathway plays a significant role in the development of BCCs, and inhibitors of this pathway, such as vismodegib, have shown promise in the treatment of these tumors. However, the development of resistance and significant side effects associated with vismodegib use highlights the need for further research into alternative Hh pathway inhibitors and combination therapies.
