The top 10 genes

• TP53: The TP53 gene, also known as p53, is a tumor suppressor gene that plays a critical role in preventing cancer. Mutations in TP53 are present in up to 50% of all cancers and are associated with a worse prognosis. TP53 acts as a transcription factor, regulating the expression of genes involved in cell cycle control, DNA repair, and apoptosis. When DNA is damaged, p53 is activated, leading to cell cycle arrest, DNA repair, or apoptosis if the damage is too severe.

• TNF: Tumor necrosis factor (TNF) is a cytokine that plays a critical role in the immune response to cancer and infectious diseases. TNF is produced by immune cells, such as macrophages and T cells, and can induce apoptosis in cancer cells. In addition, TNF has been targeted by drugs to treat autoimmune diseases, such as rheumatoid arthritis and psoriasis.

• EGFR: Epidermal growth factor receptor (EGFR) is a transmembrane receptor that binds to epidermal growth factor (EGF) and other ligands to activate downstream signaling pathways. EGFR is frequently mutated in cancers, particularly in lung cancer, and mutations in EGFR can lead to resistance to chemotherapy and targeted therapies. EGFR-targeting drugs, such as gefitinib and erlotinib, have been developed to treat lung cancer and other cancers that overexpress EGFR.

• VEGFA: Vascular endothelial growth factor A (VEGFA) is a protein that promotes angiogenesis, the formation of new blood vessels. VEGFA is overexpressed in many cancers, including breast, lung, and colon cancer, and plays a critical role in tumor growth and metastasis. Drugs targeting VEGFA, such as bevacizumab and ranibizumab, have been developed to inhibit angiogenesis and treat cancer.

• APOE: Apolipoprotein E (APOE) is a protein involved in lipid metabolism and is important for the transportation of cholesterol and other lipids in the bloodstream. APOE has also been implicated in Alzheimer's disease, as individuals with a certain APOE allele have an increased risk of developing the disease.

• IL6: Interleukin 6 (IL6) is a cytokine that plays a critical role in the immune response to infection and inflammation. IL6 is produced by immune cells, such as T cells and macrophages, and can activate downstream signaling pathways that lead to inflammation and fever. IL6 has also been implicated in cancer, as high levels of IL6 in the bloodstream have been associated with a worse prognosis.

• TGFB1: Transforming growth factor beta 1 (TGFB1) is a cytokine that plays a critical role in cell proliferation, differentiation, and immune regulation. TGFB1 is produced by immune cells, such as T cells and macrophages, and can activate downstream signaling pathways that lead to cell cycle arrest and apoptosis. In addition, TGFB1 has been implicated in cancer, as it can promote tumor growth and metastasis.

• MTHFR (Methylenetetrahydrofolate reductase) is an enzyme that plays a critical role in the metabolism of amino acids. Specifically, MTHFR is involved in the conversion of homocysteine to methionine, which is essential for the production of S-adenosylmethionine (SAMe). SAMe is a methyl donor that is important for the methylation of DNA, RNA, and proteins, and is involved in many cellular processes including gene expression, protein synthesis, and cell signaling. Mutations in the MTHFR gene can lead to reduced activity of the enzyme, which can result in elevated levels of homocysteine in the blood. Elevated homocysteine levels have been linked to a number of health problems, including cardiovascular disease, stroke, and neural tube defects in newborns. Some studies have also suggested that MTHFR mutations may be associated with an increased risk of certain types of cancer, although the evidence is not conclusive.

• ESR1 (Oestrogen receptor 1) is a protein that plays a critical role in the response to estrogen in many tissues, including the breast, uterus, and bone. The ESR1 gene codes for the estrogen receptor alpha, which is a nuclear receptor that binds to estrogen and regulates the expression of many genes. In breast cancer, ESR1 is often overexpressed, and is a major driver of the disease. Targeting ESR1 with drugs like tamoxifen or aromatase inhibitors has been a key strategy in the treatment of estrogen receptor-positive breast cancer.

• AKT1 (also known as protein kinase B) is a serine/threonine kinase that is involved in many cellular processes, including cell proliferation, apoptosis, and metabolism. AKT1 is activated by a variety of stimuli, including growth factors, cytokines, and extracellular matrix proteins. Once activated, AKT1 phosphorylates a number of downstream targets, including transcription factors, enzymes, and cytoskeletal proteins, leading to changes in gene expression, metabolism, and cell morphology. Mutations in AKT1 have been identified in a number of different cancers, including breast, colorectal, and ovarian cancer. In many cases, these mutations lead to increased AKT1 activity, which can promote cell survival and proliferation, and can also confer resistance to chemotherapy and other cancer treatments. As a result, AKT1 inhibitors are being developed as a potential therapeutic strategy for cancer treatment.
