The TP53 gene is the most frequently mutated gene (>50%) in human cancer, indicating that the TP53 gene plays a crucial role in preventing cancer formation. [5] TP53 gene encodes proteins that bind to DNA and regulate gene expression to prevent mutations of the genome. [ 12 ]
Li–Fraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder [1] that predisposes carriers to cancer development.It was named after two American physicians, Frederick Pei Li and Joseph F. Fraumeni Jr., who first recognized the syndrome after reviewing the medical records and death certificates of childhood rhabdomyosarcoma patients. [2]
The p53 p63 p73 family is a family of tumor suppressor genes. [1] [2] This gene family codes the proteins: p53; TP73L (also known as "p63") p73; They are sometimes considered part of a "p53 family." When overexpressed, these proteins are known to be involved in tumor pathogenesis. [3]
The p53 (a tumor suppressor gene in the normal population) genome on 17p in neurofibrosarcoma patients is mutated, increasing the probability of cancer. The normal p53 gene will regulate cell growth and inhibit any uncontrollable cell growth in the healthy population; since p53 is inactivated in neurofibrosarcoma patients, they are much more ...
TP-53 is a gene that encodes for the protein p53; this protein is a tumor suppressor. p53 was discovered in 1979 stemming from a study involving cancer immunology and the role of viruses in some cancers. The protein was so named because it was measured to have a weight of 53 kDa.
Most cases of lung cancer are because of genetic mutations in EGFR, KRAS, STK11 (also known as LKB1), TP53 (also known as p53), and CDKN2A (also known as p16 or INK4a) [117] [118] [119] with the most common type of lung cancer being an inactivation at p16. p16 is a tumor suppressor protein that occurs in mostly in humans the functional ...
Notable examples of potentially predictive cancer biomarkers include mutations on genes KRAS, p53, EGFR, erbB2 for colorectal, esophageal, liver, and pancreatic cancer; mutations of genes BRCA1 and BRCA2 for breast and ovarian cancer; abnormal methylation of tumor suppressor genes p16, CDKN2B, and p14ARF for brain cancer; hypermethylation of ...
Tumor suppressor p53-binding protein 1 also known as p53-binding protein 1 or 53BP1 is a protein that in humans is encoded by the TP53BP1 gene. [ 5 ] [ 6 ] [ 7 ] Clinical significance
