The study in vivo assessed the effect of pinostrobin on the histology, immunohistochemistry, and biochemical parameters of thioacetamide (TAA) induced liver cirrhosis in Sprague Dawley rats. The rats were noticeably gavaged with two doses of pinostrobin (30 mg/kg and 60 mg/kg) with TAA and exhibited a substantial decrease in the liver index and hepatocyte propagation with much minor cell injury. These groups meaningfully down-regulated the proliferation of cellular nucleus antigen (PCNA) and alpha-smooth muscle actin (α-SMA). The liver homogenate displayed augmented antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) activities escorted with reducing in malondialdehyde (MDA) level. The serum level of bilirubin, total protein, albumin, and liver enzymes (ALP, ALT, and AST) returned to normal and was similar to that of normal control and silymarin with TAA-treated groups. pinostrobin-fed groups also decreased the level of Tumor necrosis factor-alpha (TNF-α), Interleukin-6 (IL-6), and increased the level of Interleukin-10 (IL-10). Acute toxicity with a higher dose of 500 mg/kg of pinostrobin did not manifest any toxicological signs in rats. The hepatoprotective effect of pinostrobin could be due to potentially inhibited the progression of liver cirrhosis, down-regulation of PCNA and α-SMA proliferation, prevented oxidation of hepatocytes, improved SOD and CAT enzymes, condensed MDA, repairs of liver biomarkers, reduced cellular inflammation and modulation of inflammatory cytokines.
