Co-Adjuvancy of Solasodine & CoQ10 Against High Fat Diet-Induced Insulin Resistance Rats Via Modulating IRS-I and PPAR-γ Proteins Expression

Insulin resistance (IR) is a condition in which target cells become insensitive to normal Insulin concentrations in order to deliver glucose. The goal of this study was to see if solasodine combined with coenzyme Q10 could help rats with Insulin resistance caused by a high-fat diet (HFD) by regulating the expression of IRS-I and PPAR-γ proteins.One of the six groups (n=6) got a conventional diet for 16 weeks as a control (normal), the HFD was given to the other five groups for 16 weeks, which further classified as-one group as HFD control while Others treated with pioglitazone (10 mg/kg), coenzyme Q10 (50 mg/kg), solasodine (50 mg/kg) and combination of solasodine and coenzyme Q10i.e. SDQ10 (total 50 mg/kg) for the last 4 weeks orally once daily. Blood and tissue samples were collected by the end of study period for the biochemical and histological studies. As a result, HFD fed rats exhibited a significant increase in food and energy intake, body mass index, kidney and pancreas weight, fasting glucose, glycosylated haemoglobin, Insulin level, liver Enzyme ALT and AST and decrease antioxidant activity of superoxide dismutase and catalase. HFD received Animals also produced a lower level of p-IRS1 and PPAR-y protein expression in western blot analysis. SDQ10 in combination successfully restored the above-mentioned complexity of Insulin resistance caused by aHFD. Besides, increasesthe antioxidant activity of superoxide dismutase and catalase and normalized the architecture of kidney, pancreas and adipose tissue as well astreatment with SDQ10 raised the level of p-IRS1 and PPAR-y protein in liver tissue. As a result, supplementing with solasodine and coenzyme Q10 reversed the effect of the HFD on p-IRS1 and PPAR-y protein in liver tissue while also alleviating Insulin resistance symptoms.
