Cancer is a major cause of death and of the populations that Thailand is directly tied to cancer, genetic material, and the body's immune system, but the cancer will require complex steps to occur. By education, understand the mechanisms of cancer need to be aware of the cells and genetically altered to be the Foundation of education. By then the cancer will have the genes involved in 4 major groups include: 1. Tumor suppressor genes 2. Oncogene 3. DNA repair gene 4. Telomerase gene1. Tumor suppressor genes Typically, these genes control cell division, not too much. In which normal gene function in order to control cells, inhibits tumor suppressor genes, but the balance is one cause of cancer by inhibiting it caused many possible reasons, such as a missing gene that particular location (Allele loss) missing chromosome (chromosome deletion) gene is located, or to change the level DNA mutation occurs, make the abnormal gene loses the ability to control cell division.2. Oncogene Create many types of oncoproteins Oncogene that qualifies it as a growth factor, growth factor receptors, protein kinases, tyrosine kinases, a protein serine-threonine proteins (G-protein) and guanine nucleotide-binding nuclear protein, which is a protein substance produced will be able to stimulate the cells to grow and divide the number of. 3. DNA repair gene A gene that made officers repair gene when the gene is damaged or there is an abnormal gene to the gene's function, if such waste is inevitably affect subsequent.4. Telomerase gene The enzyme telomerase in human telomeric DNA is a tandem repeats of nucleotides AGGGTT that telomerase helps to add nucleotides which is tandem repeat visit to be a primer, the incoming DNA synthesis in captures and there's another one, so as long as the original chromosome, and prevent the loss of important genes are located near the distal chromosome. In somatic cells age more enzyme telomerase does not work and thus, telomere shortening, but if telomerase dysfunction is more work, it would make the chromosome length. Cell Division without limit, which is found in some types of cancer cells present, thus this knowledge to develop a substance that inhibits telomerase to make ends of chromosomes shorten the cancer cells will eventually die.Genes associated with cancer. When there is an abnormal gene mentioned the following can result in the risk of breast cancer.[Oncogene]The gene for the growth factor receptors, or creation.PDGF platelet derived growth factor for the creation of sections associated with the occurrence of glioma.Epidermal growth factor receptor of erb-B created, associated with the occurrence of breast cancer and glioblastoma.Erb-B2 called HER-2 or growth factor receptor neu created associated with salivary gland, breast cancer recurrence, and ovarian cancer.Create a growth factor receptor RET involve thyroid cancer occurs.The gene for the stimulatory pathway signaling relay transmissionKi-ras associated with the lung, ovarian, colon and caused pancreatic cancer.N-ras associated with the occurrence of leukemiaThe genes for transcription factors that activate genes growth-promotingC-myc associated with the occurrence of leukemia, breast, stomach and lung cancer.N-myc associated with the occurrence of neuroblastoma (nerve cell cancer) and glioblastoma.L-myc associated with the occurrence of lung cancerGenes for other molecules. Bcl-2 for prevention of apoptosis proteins associated with the occurrence of follicular B cell lymphoma.Bcl-1 is sometimes called cyclin D1 is a PRAD1 for the help, cell cycle continue. Involved with the occurrence of breast cancer, head and neck.MDM2 protein p53 is a tumor for per protein antagonist suppressor is involved with other cancers, sarcomas, and birth.[Tumor suppressor genes]The gene for the protein in the cytoplasmAPC is involved with the occurrence of stomach cancer.DPC4 for transmitter molecules that affect the inhibition of cell division is involved with the occurrence of pancreatic cancer.NF-1 for a protein that inhibits the functioning of Ras protein is involved with the occurrence of neurofibroma and pheochromocytoma (a cancer of the peripheral nervous system) and myeloid leukemia.NF-2 associated with meningioma and ependymoma occurrence (brain cancer) and schwannoma.The gene for the protein in the nucleus.MTS1 for p16 protein that acts destroy the cell cycle associated with cancer in several systems.Cell cycle inhibitor protein pRB for RB is involved with the occurrence of retinoblastoma, bladder, bone, lung and breast cancer cell small.P53 protein p53 causes cell cycle for stop and induced apoptosis of abnormal cells. Involved with several cancer system.WT1 are associated with the occurrence of Wilm's tumor that kidney.The gene for the protein in the cells, but not in the position found.BRCA1 associated ovarian cancer recurrence with breast andBRCA2 associated breast cancer recurrence with.VHL is involved with the occurrence of renal cell cancer.
