From: Expression of RSK4, CD44 and MMP-9 is upregulated and positively correlated in metastatic ccRCC
The expression of the RSK4, CD44 and MMP-9 proteins varies in primary ccRCCs and metastatic ccRCCs. a, d; b, e; c, f are form the same patients. a-c: primary ccRCCs, d-e: metastatic ccRCCs, × 400. a weak positivity for RSK4 protein. b weak positivity for CD44 protein. c weak positivity for MMP-9 protein. d positivity for RSK4 protein. e positivity for CD44 protein. f positivity for MMP-9 protein
