Connexin 32 and luteolin play protective roles in non-alcoholic steatohepatitis development and its related hepatocarcinogenesis in rats

Abstract: Non-alcoholic steatohepatitis (NASH) has the potential to lead to the development of cirrhosis and hepatocellular carcinoma (HCC). Connexin (Cx) 32, a hepatocyte gap-junction protein, plays a preventive role in hepatocarcinogenesis. However, the precise contribution of Cx32 in the development of NASH has not been established. In this study, we aimed to clarify the role of Cx32 and the chemopreventive effect of luteolin, an antioxidant flavonoid, on the progression of NASH and NASH-related hepatocarcinogenesis.… Show more

“…Multiple prior investigations have demonstrated the critical role of Cx32 gap junctions in establishing injury in various models of liver disease 11, 12, 13. In particular, recent data have highlighted that perturbations in Cx32 are associated with the development of NAFLD in dietary animal models 14, 15, 16, 17…”

“…Sabe-se que os hemicanais das conexinas Cx32 e Cx43 desempenham papéis chaves na apoptose hepática (VINKEN et al, 2010;VINKEN, 2012 Sagawa et al (2015), relatou um efeito protetor da Cx32 na progressão da EHNA em ratos submetidos à dieta deficiente em colina e metionina.…”

“…A partir da classificação histopatológica proposta por Kleiner et al (2005),os cortes histológicosdo fígado de animais WT e Cx32-KO foram avaliados e não foram observadas diferenças significativas em nenhum dos parâmetros semi-quantitativos analisados. De maneira similar, Sagawa et al (2015) demonstraram que ratos transgênicos dominantes negativos para Cx32 (Cx32-Tg), submetidos à injeção única de DEN (200mg/kg) e 2 semanas de dieta deficiente em colina e metionina, apresentaram esteatose na mesma intensidade dos animais WT, porém, apenas os animais Cx32-Tg apresentaram infiltrado inflamatório. Após 12 semanas de dieta, os autores relataram intensa esteatose em ambos os grupos, porém maior quantidade de infiltrado inflamatório, células balonizadas e, consequentemente, índice NAS nos animais Cx32-Tg.…”
