Abstract:
BACKGROUND:Recently, several studies have investigated the relationship between Pre-miR-27a rs895819 polymorphism and risk of various cancers. However, the relationship between rs895819 and diffuse large B-cell lymphoma (DLBCL) has not been well known. METHODS:In this study, we conducted a case-control study to explore the role of Pre-miR-27a rs895819 in risk of DLBCL. The PCR-TaqMan and luciferase assays and in vitro experiments were used to evaluate polymorphism function. RESULTS:As a result, we found subjects carrying with rs895819 AG/GG genotype had a significantly decreased risk when compared with those carrying the AA genotype. Further qPCR assay showed that the DLBCL patients carrying AG/GG genotypes showed a lower level of mature miR-27a when compared with patients carrying AA genotype. Moreover, miR-27a levels were upregulated in DLBCL tissues compared with normal lymphoid tissues. Further in vitro experiments showed that miR-27a might function as an oncogene through target TGFBR1. In addition, TGFBR1 overexpression rescues effects of miR-27a inhibitor on DLBCL cells phenotypes. CONCLUSIONS:In conclusion, these findings indicate that rs895819 A > G might reduce the expression of mature miR-27a, and leading a higher level of TGFBR1, ultimately inhibiting the development of DLBCL.
