Chronic kidney disease (CKD) is a global health problem, and novel therapies to treat CKD are urgently needed. Here, we show that inhibition of G0/G1 switch 2 (G0s2) ameliorates renal inflammation in a mouse model of CKD. Renal expression of chemokine (C-C motif) ligand 2 (Ccl2) was increased in response to p65 activation in the kidneys of wild-type 5/6 nephrectomy (5/6Nx) mice. Moreover, 5/6Nx Clk/Clk mice, which carry homozygous mutations in the gene encoding circadian locomotor output cycles kaput (CLOCK), did not exhibit aggravation of apoptosis or induction of F4/80-positive cells. The renal expression of G0s2 in wild-type 5/6Nx mice was important for the transactivation of Ccl2 by p65. These pathologies were ameliorated by G0s2 knockdown. Furthermore, a novel small-molecule inhibitor of G0s2 expression was identified by high-throughput chemical screening, and the inhibitor suppressed renal inflammation in 5/6Nx mice. These findings indicated that G0s2 inhibitors may have applications in the treatment of CKD. Chronic renal inflammation in CKD was ameliorated by clock mutation. G0s2 was important for the anti-inflammatory effects of clock mutation. A novel small-molecule inhibitor of G0s2 ameliorated renal inflammation in CKD. Matsunaga et al. found that G0/G1 switch 2 (G0s2) was important for renal inflammation and that a novel small-molecule inhibitor of G0s2 ameliorated renal dysfunction in chronic renal disease (CKD). G0s2 enhanced p65-mediated transcription. Moreover, renal inflammation was regulated by G0s2/Stat5 through the molecular clock mechanism. Finally, G0s2 knockdown or inhibition ameliorated renal dysfunction in CKD.
