Naringenin is a bioflavonoid drug potentially for the treatment of HCV infection. has antioxidant and chelating effects in the liver. Naringenin significantly suppressed UVB-induced extracellular signal-regulated kinase 2 (ERK2) activity and subsequently attenuated UVB-induced phosphorylation of p90(RSK) by competitively binding with ATP. Naringenin exerts potent anti-photoaging effects by suppressing ERK2 activity and decreasing FRA1 stability, followed by down-regulation of AP-1 transactivation and MMP-1 expression. Naringenin blocks TGF-β1 trafficking from the trans-Golgi network by suppressing PKC activity, resulting in a reduction of TGF-β1 secretion from breast cancer cells.
