The active constituent profile in Cape gooseberry (Physalis peruvianaL.) juice was determined by GC-MS. Quercetin and kaempferol were active components in the juice. In this study we have evaluated its potential protective effect on hepatic injury and fibrosis induced by carbon tetrachloride (CCl4). Twenty-eight rats divided into 4 groups: Group I served as control group, and Group II received weekly i.p. injection of 2 mL CCl4/kg bwt for 12 weeks. Group III were supplemented with Physalis juice via the drinking water. The animals of Group IV received Physalis juice as Group III and also were intraperitoneally injected weekly with 2 mL CCl4/kg bwt for 12 weeks. Hepatoprotective effect was evaluated by improvement in liver enzymes serum levels, reduction in collagen areas, downregulation in expression of the fibrotic marker MMP-9, reduction in the peroxidative marker malonaldehyde and the inflammatory marker nitric oxide, and restoration of the activity of antioxidant enzymatic and nonenzymatic systems, namely, glutathione content, superoxide dismutase, catalase, glutathione-S-transferase, glutathione peroxidase, and glutathione reductase activities. The results show that the potential hepatoprotective effects ofPhysalis peruvianamay be due to physalis acts by promotion of processes that restore hepatolobular architecture and through the inhibition of oxidative stress pathway.

A well-known natural ingredient found in several medicinal plants, berberine (Ber), has been shown to have anticancer properties against a range of malignancies. The limited solubility and bioavailability of berberine can be addressed using Ber-loaded nanoparticles. In this study, we compared the in vitro cytotoxic effects of both Ber-loaded silver nanoparticles (Ber-AgNPs) and Ber-loaded selenium nanoparticles (Ber-SeNPs) in the human liver cancer cell line (HepG2) and mouse normal liver cells (BNL). The IC50 values in HepG2 for berberine, Ber-AgNPs, Ber-SeNPs, and cisplatin were 26.69, 1.16, 0.04, and 0.33 µg/mL, respectively. Our results show that Ber and its Ag and Se nanoparticles exerted a good antitumor effect against HepG2 cells by inducing apoptosis via upregulating p53, Bax, cytosolic cytochrome C levels, and caspase-3 activity, and the down-regulation of Bcl-2 levels. Similarly, incubation with Ber and both Ber-NPs (Ag and Se) led to a significant dose-dependent elevation in inflammatory markers’ (TNF-α, NF-κB, and COX-2) levels compared to the control group. In addition, it led to the arrest of the G1 cell cycle by depleting the expression of cyclin D1 and CDK-2 mRNA. Furthermore, Ber and both Ber-NPs (Ag and Se) caused a significant dose-dependent increase in LDH activity in HepG2 cells. Furthermore, our findings offer evidence that Ber and its nanoparticles intensified oxidative stress in HepG2 cells. Furthermore, the migration rate of cells subjected to berberine and its nanoforms was notably decreased compared to that of control cells. It can be inferred that Ber nanoparticles exhibited superior anticancer efficacy against HepG2 compared to unprocessed Ber, perhaps due to their improved solubility and bioavailability. Furthermore, Ber-SeNPs exhibited greater efficacy than Ber-AgNPs, possibly as a result of the inherent anticancer characteristics of selenium.

Plant derived phytochemical therapy is a bright candidate for treatment of diabetes and its associated complications. Ocimum baslicum is used as an anti-diabetic traditional medicine. Hence, the present study investigated the effect of Hail Ocimum extract (HOE) and its total flavonoids (HOETF) against hepatorenal damage in experimental diabetes induced by high-fat diet (HFD) and injection of streptozotocin (STZ) in rats. Diabetic animals were co-treated daily with HOE, HOETF or metformin (MET) as a standard anti-diabetic drug for four weeks. Compared to controls, HFD/STZ-treatment lead to significant increases in fasting blood glucose, insulin and HOMA-IR levels. Furthermore, diabetic rats had elevated hepatic (ALT and ALP) and kidney functions (urea and creatinine) biomarkers together with disturbed lipid profile and decreased PPAR-γ gene expression. Higher levels of hepatic and renal LPO and NO paralleled with lower levels of GSH and activities of antioxidant enzymes (SOD, CAT, GPx and GR) after HFD/STZ treatment. Additionally, noteworthy inflammatory and apoptotic responses were evident in both organs of diabetic rats as witnessed by augmented levels of TNF-α, IL-1b and Bax levels with declined levels of Bcl-2. Moreover, histological examination of hepatic, renal and pancreatic tissues validated the biochemical findings. On contrary, co-treatment of diabetic animals with HOE or HOETF could decrease glucose and insulin levels together with improvement of lipid markers and alleviation of hepatorenal dysfunction, oxidative injury, inflammatory and apoptotic events. Conclusively, HOE or HOETF could be a promising complementary therapeutic option for the management of diabetic hepatorenal complication owing to their antioxidant, anti-inflammatory; anti-apoptotic properties.
