THE STUDY OF POLYMORPHISMS OF XPD GENE A751C IN LUNG CANCER PATIENTS WITH DIFFERENT CLINICAL AND MORPHOLOGICAL
Abstract:
There were studied distribution of polymorphic variants of gene of repair of DNA XPD A751C in lung cancer depending on histological type of tumor (small cell / non-small cell lung cancer) and the prevalence of tumor process (with foci / without foci of metastasis). It was found a significant increase in the incidence of minor allele C, CC and AC genotypes of the polymorphic site of gene XPD A751C in patients with lung cancer. We estimated relative risks of lung cancer development in carriers of polymorphic variants of gene XPD A751C. The heterozygous genotype AC polymorphism of gene XPD A751C is characterized by the greatest risk of developing lung cancer with small cell histological type. Homozygous CC genotype of the polymorphic site of gene XPD A751C is associated with non-small cell lung cancer development. Statistically significant differences in the distribution of polymorphic variants of gene A751C XPD depending on spread of cancer were not received.

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.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
