Suppression of PPARγ expression by CDKAL1 contributes to the anti-adipogenic action of CDKAL1. (a,b) Time course of gene expression levels of early adipogenic regulators, C/EBPβ and C/EBPδ (a) and late regulators, PPARγ and C/EBPα (b) during adipocyte differentiation of 3T3-L1 cells expressing CDKAL1 (n = 3). (c,d) Effect of PPARγ agonist pioglitazone on lipid accumulation (c) and gene expression (d) in differentiated 3T3-L1 cells expressing CDKAL1 (n = 3). (e,f) Effect of coexpression of PPARγ on lipid accumulation (e) and gene expression (f) in differentiated 3T3-L1 cells expressing CDKAL1 (n = 3, **p < 0.005, ***p < 0.0005 vs control group by Dunnett’s test).
