Curcumin can suppress hepatic stellate cell (HSC) activation and modulate liver inflammatory injury by upregulation of PPARγ, which can increase apoptosis or decrease cyclin D1 and proliferation to inhibit angiogenesis/cell growth, and also can cause a reduction in TGF-β signaling and extracellular matrix in regard to inhibition of HSC activation and liver fibrosis [22]. The gene discussed is TGFB1; the disease is Hepatic fibrosis.
