Functional Assessment of MGO Nanoparticle Supplementation in an Acute Liver Injury Rat Model

Abstract

Magnesium supplements have been effective for modulating process of bile resistance, decrease oxidative stress and systemic inflammation. Current study was designed to functionally evaluate the MgO nanoparticle supplementation in an acute liver injury rat model. The animals were randomly divided into five groups. All groups were administrated with CCl4 to induce hepatic injury except of negative control group which received only vehicle. CCl4 administration is followed by MgO nanoparticles in the concentration of 150 and 300 mg/kg in low dose and high dose treated group respectively except of standard control group. After 21 days of treatment, the animals were sacrificed to collect blood and liver samples. Serum levels of bilirubin, AST, ALT and ALP were determined. Liver sample was also subjected to RNA isolation by Trizol method followed by the cDNA synthesis and Real Time PCR. In addition, lipid profile was also assessed. The data obtained was analyzed by one way analysis of variance (ANOVA). The results showed that levels of bilirubin, AST, ALT and ALP were significantly elevated in positive control group while MgO treated groups, somehow, had normal ranges of these enzymes. Furthermore, the qPCR results showed that the expression of Farnesoid X receptor (FXR), transcriptional regulator of the bile salt export pump (BSEP) and sodium taurocholate cotransporting polypeptide (NTCP), is reduced in positive control group, while nanoparticles treated groups had normal expression of these genes. In conclusion, our data showed that MgO nanoparticles possess hepatoprotective activity against hepatic injury.
