Liver tissue malfunction is a severe worldwide health concern that arises from various chronic liver conditions. The goal of this investigation was to look into the anti-fibrotic effect of apigenin (APG), an antioxidant found in various plants, versus thioacetamide (TAA)-triggered hepatic scarring in rats and the potential mechanisms behind it.

TAA was administered thrice weekly (100 mg/kg, i.p.) for two weeks to produce hepatic scarring. APG was administered after TAA for 14 days (5 or 10 mg/kg, orally). Thereafter, hepatic liver enzymes, inflammatory markers, fibrotic indicators, and histopathological changes were evaluated.

TAA increased the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), reduced albumin and total protein, elevated hepatic level of lipid peroxidation, focal adhesion kinase (FAK), hypoxia-inducible factor-1α (HIF-1α), and inflammatory cytokines, decreased interleukin-10 (IL-10), reduced hepatic expression of peroxisome proliferator-activated receptor gamma (PPARγ) and nuclear factor-erythroid factor 2-related factor 2 (Nrf2), and elevated serine-threonine protein kinase (AKT) expression. Furthermore, TAA increased hepatic contents of collagen I, connective tissue growth factor (CTGF), hydroxyproline, and alpha-smooth muscle actin. On the other hand, APG evaded these changes and mitigated the harmful effects of TAA in a dose-dependent way. Histopathological and immunohistochemical observations reinforced these biochemical outcomes.

APG can potentially alleviate liver fibrosis mediated via FAK and HIF1 inhibiting signaling pathways.

Apricot (Prunus armeniaca L.) has been widely used for the treatment of several disorders such as liver diseases, but the hepatoprotective and anticancer activities of its seeds were not studied before. In this study, we evaluated the pharmacological effects of apricot seeds extracts and amygdalin on prevention of liver damage and treatment of hepatocellular carcinoma.

Amygdalin contents of apricot seeds in ethanolic extracts were determined using high performance liquid chromatography (HPLC) then, the ethanolic apricot seeds extract and amygdalin were evaluated for its hepatoprotective activity against carbon tetrachloride-induced hepatotoxicity and anticancer activity against N-nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis.

The amount of amygdalin was 5.72 g and 10.22 g/100 g extract for 70% and 99.9% ethanolic apricot seeds extracts, respectively. Pretreatment of the rats with 70% and 99.9% ethanolic apricot seeds extracts (100 mg/kg), amygdalin and silymarin (50 mg/kg) prevented elevation in liver function parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) caused by carbon tetrachloride injection with significant increase in albumin, total proteins, and no effect on total direct bilirubin when compared to those in hepatotoxic group. Both extracts also showed anticancer activity against hepatocellular carcinoma via diminishing the elevated serum levels of AST, ALT, ALP, total, direct bilirubin, albumin, total proteins, alpha-fetoprotein, malondialdehyde (MDA) and nitric oxide (NO) and elevating the decreased hepatic reduced glutathione (GSH) level when compared with NDEA- intoxicated group.

Apricot seeds possess hepatoprotective and anticancer activities that justify its traditional use, and its potential for the treatment of liver diseases including hepatocellular carcinoma.
