High glucose decreased Suv39h1 levels via PI3K in mesangial cells.
High glucose and chaetocin decreased histone H3K9me3 levels at the promoters of fibronectin and p21WAF1 genes.
Suv39h1 overexpression attenuated high glucose-induced cell hypertrophy and expressions of fibronectin and p21WAF1 genes while attenuating HG-suppressed histone H3K9me3 levels at the promoters of fibronectin and p21WAF1 genes.
