Effects of exogenous thymosin β4 on carbon tetrachloride-induced liver injury and fibrosis

Abstract The present study investigated the effects of exogenous thymosin β4 (TB4) on carbon tetrachloride (CCl4)-induced acute liver injury and fibrosis in rodent animals. Results showed that both in mice and rats CCl4 rendered significant increases in serum alanine aminotransferase and aspartate a...
