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]
Even though PUMA function is compromised in most cancer cells, it does not appear that genetic inactivation of PUMA is a direct target of cancer. [ 36 ] [ 37 ] [ 38 ] Many cancers do exhibit p53 gene mutations, making gene therapies that target this gene [ clarification needed ] impossible, but an alternate pathway may be to focus on ...
WRAP53 (also known as WD40-encoding RNA antisense to p53) is a gene implicated in cancer development. The name was coined in 2009 to describe the dual role of this gene, encoding both an antisense RNA that regulates the p53 tumor suppressor and a protein involved in DNA repair, telomere elongation and maintenance of nuclear organelles Cajal bodies (Figure 1).
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 ...
Rb and p53 regulate the transition between G1 and S phase, arresting the cell cycle before DNA replication until the appropriate checkpoint inputs, such as DNA damage repair, are completed. [20] p53 regulates the p21 gene, which produces a protein which binds to the Cyclin D-Cdk4/6 complex. [21]

P53 diverged from p63/p73 with a gene duplication in the cartilaginous fish. [7] P63 and p73 differentiated from each other in bony fish. [ 7 ] In vertebrates, p53 began the role of protecting the somatic cells and acting as a tumor suppressor.
Using molecular biological techniques, it is possible to characterize the mutations, epimutations or chromosomal aberrations within a tumor, and rapid progress is being made in the field of predicting certain cancer patients' prognosis based on the spectrum of mutations. For example, up to half of all tumors have a defective p53 gene.
