1 Interleukin-6 deficiency accelerates cisplatin-induced acute renal failure but not systemic injury. Cisplatin interleukin 6 Mus musculus
2 In this study, we analyzed IL-6 regulation during CDDP-induced ARF in wild-type (WT) mice and determined the pathological role of IL-6 using IL-6 knockout ((-/-)) mice. Cisplatin interleukin 6 Mus musculus
3 Renal IL-6 expression in most proximal tubular cells and suppressor of cytokine signaling 3 (SOCS3) gene expression significantly increased in WT mice after administration of CDDP, suggesting active IL-6 signaling during CDDP-induced ARF development. Cisplatin interleukin 6 Mus musculus
4 Renal IL-6 expression in most proximal tubular cells and suppressor of cytokine signaling 3 (SOCS3) gene expression significantly increased in WT mice after administration of CDDP, suggesting active IL-6 signaling during CDDP-induced ARF development. Cisplatin interleukin 6 Mus musculus
5 Renal IL-6 expression in most proximal tubular cells and suppressor of cytokine signaling 3 (SOCS3) gene expression significantly increased in WT mice after administration of CDDP, suggesting active IL-6 signaling during CDDP-induced ARF development. Cisplatin interleukin 6 Mus musculus
6 Interestingly, renal dysfunction occurred soon after administration of CDDP and became more severe in IL-6(-/-) mice than that in WT mice. Cisplatin interleukin 6 Mus musculus
7 Bax might contribute to the development of CDDP-induced ARF at 24h; however, high expression levels of Bcl-x(L) and Bcl-2 might overcome the proapoptosis signaling at 72 h in IL-6(-/-) mice. Cisplatin interleukin 6 Mus musculus
8 These results indicated that local and systemic elevation of IL-6 contributes to the development of CDDP-induced ARF and that IL-6 produced in renal tubular cells prevents progression of ARF at the early stage. Cisplatin interleukin 6 Mus musculus
9 IL-6 deficiency accelerates CDDP-induced ARF but not development of systemic injury. Cisplatin interleukin 6 Mus musculus
