摘要: MicroRNAs (miRNAs) are a class of non-protein-coding small RNAs with the capacity to regulate fundamental biological processes essential for cancer initiation and progression. In present study, we analyzed miRNA expression levels between multidrug-resistant gastric carcinoma cell line SGC7901/ADR its parent SGC7901 using microarray. MiR-103/107 was downregulated compared parental cells. Overexpression miR-103/107 sensitized cells doxorubicin (DOX), as demonstrated by in vitro vivo drug sensitivity assay. We further confirmed that inhibited P-gp function Finally, verified caveolin-1 (Cav-1), critical component lipid rafts, target miR-103/107.
