(A to D) Real-time PCR analysis of MCP-1, MIP-1α, and RANKL mRNA expression (A, B) and ELISA analysis of secreted protein (C, D) in CD32-knockdown (CD32-KD) ARP-1 or MM.1S cells cultured with CRP (5 μg/mL), compared with those in non-target control shRNA-transfected (Ctrl) cells. (E to H) Analysis of cytokine (MCP-1, MIP-1α, and RANKL) abundance at the mRNA (E, F) and protein (G, H) levels in cultures of vector- or CD32-transfected (CD32) ARP-1 or MM.1S cells cultured with or without CRP (5 μg/mL). *P < 0.05, **
P < 0.01 by student’s t test. Data from three independent experiments are shown.
