Summary
The TP53 gene
Area of Science:
- Oncology
- Genetics
Background:
- TP53 is a critical tumor suppressor gene frequently mutated in cancers.
- A common polymorphism at codon 72 of TP53 influences P53 protein function, particularly apoptosis induction.
Purpose of the Study:
- To investigate the association between the TP53 codon 72 polymorphism and the development and prognosis of acute leukemia.
- To analyze the impact of TP53 Arg/Pro genotypes on acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML) outcomes.
Main Methods:
- Genotyping of the TP53 codon 72 polymorphism using PCR-RFLP.
- Analysis of 288 acute leukemia cases (147 ALL, 141 AML) and 245 controls.
- Correlation of genotypes with clinical variables including WBC, blast percentage, LDH levels, and DFS.
Main Results:
- A significant association was found between the homozygous arginine genotype (Arg/Arg) and the development of AML.
- ALL patients with the Arg/Arg genotype showed elevated WBC, blast percentage, LDH, and reduced DFS.
- AML patients with the Pro/Pro genotype exhibited elevated WBC, blast percentage, LDH, and reduced DFS.
Conclusions:
- The Arg/Arg genotype of the TP53 codon 72 polymorphism may increase the risk of developing acute myeloid leukemia.
- The TP53 codon 72 polymorphism appears to influence clinical characteristics and prognosis in both ALL and AML patients.

Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase
Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
Translation
Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
