Summary
TP53 codon 72 polymorphisms are not definitively linked to prostate cancer overall. However, the Arg allele may increase risk in Caucasians, but not in Asians, suggesting a low-penetrant role.
Area of Science:
- Genetics
- Oncology
- Molecular Epidemiology
Background:
- TP53 codon 72 polymorphisms have been implicated as potential risk factors for various cancers.
- Previous studies on the association between TP53 codon 72 polymorphisms and prostate carcinoma susceptibility have produced conflicting results.
- A comprehensive meta-analysis is needed to clarify the relationship between TP53 codon 72 polymorphisms and prostate cancer risk.
Purpose of the Study:
- To conduct a systematic meta-analysis to determine the association between TP53 codon 72 polymorphisms and prostate carcinoma.
- To provide a more precise estimation of the relationship by pooling data from multiple case-control studies.
- To investigate potential ethnic differences in the association between TP53 codon 72 polymorphisms and prostate cancer.
Main Methods:
- A systematic literature search was performed across major databases (Medline, EMBASE, OVID, Sciencedirect, CNKI) up to February 2009.
- Six case-control studies, comprising 582 cases and 1075 controls, met the inclusion criteria.
- Data were extracted and analyzed using meta-analysis techniques, including subgroup analysis by ethnicity.
Main Results:
- Overall, no significant association was found between TP53 codon 72 polymorphisms and prostate carcinoma risk across different genetic models.
- Subgroup analysis indicated that individuals carrying the Arg allele might have an increased susceptibility to prostate cancer in Caucasians.
- In contrast, TP53 codon 72 polymorphism was unlikely to be a risk factor for prostate cancer in Asians, and showed minimal effect on metastasis or differentiation.
Conclusions:
- TP53 codon 72 polymorphism may act as a low-penetrant risk factor for prostate carcinoma in Caucasians.
- The association between TP53 codon 72 polymorphism and prostate cancer risk differs between Caucasian and Asian populations.
- TP53 codon 72 polymorphism appears to have a limited role in the metastasis and differentiation of prostate carcinoma.

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...
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...
Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
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.
Such genes that act...
