The effect of SOCS1 on IL-1β-induced C/EBPβ expression. (a) IL-1β-induced C/EBPβ mRNA expression was significantly increased in SW1353 cells with knockdown of the SOCS1 gene (gray bars), and decreased in the SOCS1-overexpressing SW1353 cells after 8 h (black bars; n=3). (b) A representative immunoblot showing that IL-1β-induced expression of the C/EBPβ protein was lower in SOCS1-overexpressing SW1353 cells than in other cells (lane 1, empty vector; lane 2, SOCS1 vector; lane 3, scramble shRNA; lane 4, SOCS1 shRNA). (c) SOCS1 decreased the levels of IL-1β-induced C/EBPβ transcript and protein expression in human articular chondrocytes (HACs) electrotransfected with the SOCS1 vector (n=5). (d) C/EBPβ knockdown or overexpression did not affect the levels of SOCS1 mRNA upon IL-1β stimulation (n=3). Data are expressed as the mean±s.e.m. *P<0.05.
