hsa-miR-631 resensitizes bortezomib-resistant multiple myeloma cell lines by inhibiting UbcH10.

Although bortezomib (BTZ) remains a first-line agent for multiple myeloma (MM) therapy, the development of BTZ resistance has become an indicator of poor prognosis in MM patients. It is thus urgent to develop strategies to restore the vulnerability of MM to BTZ. This study demonstrated, for the first time, that UbcH10 is highly expressed in BTZ-resistant myeloma cell lines U-266/BTZ, NCI-H929/BTZ and RPMI-8226/BTZ, which is attributed to the inactivation of post-transcriptional control.

CXCL12 G801A polymorphism and cancer risk: An updated meta-analysis.

Many studies have reported the relationship between CXCL12 G801A polymorphism and cancer risk, with conflicting results. In this study, we tried to clarify the possibility that this polymorphism may increase cancer risk by conducting an updated meta-analysis. PubMed and EMbase were searched for case-control studies regarding the association of the gene polymorphism and cancer risk.
