RPL32 knockdown decreases the expression levels of MMP-2 and MMP-9. (A) Western blot analysis indicated that the (B) protein expression levels of both MMP-9 and MMP-2 were lower in 1315-KD cells compared with 1315-CON cells. 1315-CON and SUM 1315 cells were stably transfected with negative control lentivirus. 1315-KD and SUM 1315 cells were stably transfected with RPL32 siRNA lentivirus. *P<0.05 vs. 1315-CON. RPL32, ribosomal protein L32; MMP, matrix metalloproteinase; si, small interfering; CON, control; KD, knockdown.
