Organic Cation Transporter I and Na+/taurocholate Co ?Transporting Polypeptide are Involved in Retrorsine? and Senecionine?Induced Hepatotoxicity in HepaRG cells
ConclusionOur results confirm previous findings of active transport mechanisms of PAs into hepatocytes and highlight the importance of toxicokinetic studies for the risk assessment of PAs.

Modulation of Atg5 Expression by Globular Adiponectin Contributes to Autophagy Flux and Suppression of Ethanol-Induced Cell Death in Liver Cells.
Abstract Globular adiponectin (gAcrp) protects liver cells from ethanol-induced apoptosis via induction of autophagy. However, the underlying mechanisms are unknown. The present study aims to investigate the potential role of autophagy-related protein 5 (Atg5), an essential Atg for the elongation of autophagosomes, in suppression of ethanol-induced cytotoxicity by gAcrp. Here, we demonstrated that suppression of Atg5 expression by ethanol was restored by pretreatment with gAcrp both in primary rat hepatocytes and human hepatoma cell line (HepG2). Moreover, ethanol-induced accumulation of p62 (sequestosome1), a mar...

Galangin inhibits proliferation of hepatocellular carcinoma cells by inducing endoplasmic reticulum stress.
Abstract Prolonged endoplasmic reticulum (ER) stress may activate apoptotic pathways in cancer cells. It is suggested that ER stress has the potential of enhancing tumor death in cancer therapy. Galangin, a flavonol derived from Alpinia officinarum Hance, has been shown to suppress the proliferation of hepatocellular carcinoma cells (HCC). The aim of this study was to determine whether galangin was able to induce ER stress in HepG2, Hep3B and PLC/PRF/5 cells. The proliferation of HCC was tested by MTT method. Intracellular Ca(2+) levels were measured with Fluo3-AM.The proteins levels of GRP94, GRP78 and CHOP were ...
