Abstract:

OBJECTIVE: To determine the association of Prohibitin (PHB) 3'- untranslated region (UTR) polymorphism with the risk of breast cancer in eastern Guangdong of southern China.METHODS:A case-control study of 231 breast cancer patients and 169 healthy controls were enrolled into this study. Genomic DNA was extracted from whole blood cells. Single nucleotide polymorphisms of rs1049620,rs9893420 and rs4987083 were determined by the high resolution melting (HRM) method.Data were analyzed via Logistic regression analysis and Chi-square test. RESULTS:PHB gene at rs9893420 and rs4987083 sites showed single genotype in breast cancer group and control. There were no significant differences in frequencies of G/G,A/G and A/A at rs1049620 between patients and controls(P>0.05). Meanwhile,no significant correlation could be found between rs1049620 SNP and clinico-pathologic characteristics of breast cancer such as histological classification and expression of hormone receptor. CONCLUSION: Our results do not lend support to the hypothesis that PHB polymorphism contributes to susceptibility of breast cancer.

Key words: breast cancer, Prohibitin, single nucleotide polymophism, high resolution melting
