The P53 protein is a key regulator of modified-cell apoptosis. The functional oligonucleotide polymorphism of the p53 gene causes the substitution of arginine (Arg) for praline (Pro) in the codon 72. A reduced apoptotic activity of p53 and, as a consequence, development of oncology pathology is associated with the above polymorphism. CCR5 is a compound transmembrane receptor-protein, which apart from chemokines, binds with some molecules and is a coreceptor for HIV-1. 32 bp deletion within the CCR5 encoding region results in the loss of the protein's receptor function. It has been demonstrated that the transmission of the "external" (in respect to cell) stimulus, via the CCR5 system, induces expression of the p53 gene and initiates apoptosis. Allele variants and p53 and CCR5 genotypes (separately and in combinations) were investigated, within the present case study, for 131 long-livers from Novosibirsk and Tyumen Regions. A trend was detected towards accumulation of the p53 Pro alleles in association with the CCR5del32 allele in the study group, which, as the authors believe, can enhance the genome resistance to variable factors that cut the life span.
