Figure 6. RPP30 regulated protein activation and cell proliferation in vitro. (A) Western blot showed knockdown of RPP30 led to increased expression of p-STAT3 and p-NF-κB in HA cells. (B, C) Cell proliferation ability increased significantly after knocking down RPP30 in HA cells. (D) RPP30 was lowly-expressed in GBM samples by qRT-PCR.
