Abstract:
A case-control retrospective association study was conducted to investigate a possible association of the TP53 polymorphisms, Arg72Pro and PIN3 (+16bp), with sporadic breast cancer in Croatian women. Ninety-five women with breast cancer and 108 age-matched healthy women were analyzed. Arg72Pro polymorphism was detected by TaqMan essay. For designation of PIN3 (+16bp) polymorphism DNA amplification was performed by the polymerase chain reaction (PCR) while the PCR products were detected by capillary electrophoresis. Homozygous genotype of minor allele of the PIN3 (+16bp) polymorphism was associated with sporadic breast cancer (OR = 2.15, 95% confidence interval [CI] 1.80-2.56, p = 0.006). For Arg72 polymorphism, the odds ratio for breast cancer of ArgPro versus reference genotype ArgArg was 0.55 (95% CI 0.30-1.02, p = 0.039) suggesting the protective effect. Although different haplotypes did not influence the susceptibility to the disease, the joint occurrence of genotype combination ProPro/A2A2 frequent in cases, was associated with sporadic breast cancer (OR = 2.20, 95% CI 1.89-2.56, p = 0.021). The study provides evidence of the association of the TP53 gene polymorphisms Arg72Pro and PIN3 (+16bp) with sporadic breast cancer in the Croatian population.

Cancer-Critical Genes II: Tumor Suppressor Genes
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.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
