Hyperlipidemia and hyperglycemia have been implicated in diabetes mellitus (DM) leading to complications such as nephropathy. Medicinal plants like Mormodica charantia (MC) have been used in the treatment of DM over the years but little is known about their mechanisms of action. This study used biotechnology tools to investigate and compare the effects of M. charantia silver nanoparticles (MCSNPs) with M. charantia extract on expressions of genes linked with nephrotoxicity, lipid and glucose metabolisms using reverse-transcriptase polymerase chain reaction (RT-PCR) in streptozotocin-induced diabetic rats. The genes investigated include kidney injury molecule-1 (KIM-1), 3-hydroxyl, 3-methyl glutaryl_coA reductase (HMG-CoA reductase), peroxisome proliferator-activated receptor alpha and gamma (PPARα and PPARγ). Synthesis of MCSNPs was done using 1 mM concentration of aqueous silver nitrate solution at ratio 1:9 (v/v). Experimental rats were induced intraperitoneally with streptozotocin (65 mg/kg) and divided into six groups viz: diabetic control; normal control; silver nitrate (10 mg/kg); MCSNPs (50 mg/kg); Metformin (100 mg/kg) and M. charantia fraction (100 mg/kg). Sacrifice was done after 12 days of treatment and RT-PCR was then used to investigate gene expressions in liver and kidney tissues of the rats. The expression of HMG-CoA reductase gene was significantly upregulated (p<0.05) upon treatment with 50 mg/kg MCSNPs relative to the diabetic untreated group. M. charantia extracts and MCSNPs significantly upregulate (p<0.05) the expressions of PPAR-α and PPAR-γ compared to the diabetic control. Also, a significant (p<0.05) down-regulation of KIM-1 mRNA expression was observed in MCSNPs- treated group, relative to the diabetes untreated group. M. charantia silver nanoparticles could be a potent antidiabetic agent due to its potential to modulate genes associated with lipid metabolism and nephrotoxicity.

Previous studies have demonstrated that cholesterol synthesis is increased twofold in the small intestines of rats with streptozotocin-induced diabetes. The purpose of the present study was to determine the effect of adding glucose or fructose to standard rat chow on cholesterol synthesis in control and diabetic rats. In control rats a 25% glucose or fructose diet fed for 21 days markedly inhibited hepatic cholesterol synthesis in the liver. In contrast, in diabetic animals only fructose inhibited hepatic cholesterol synthesis. In both control and diabetic animals the addition of these simple sugars to the diet did not markedly alter extrahepatic cholesterol synthesis. The enhancement of small intestinal cholesterol synthesis observed in diabetic animals was present regardless of the dietary manipulations. Further studies demonstrated that the addition of smaller concentrations of fructose (10%) to standard rat chow decreased hepatic cholesterol synthesis in both control and diabetic rats. Similarly the addition of fructose to the diet of control and diabetics for a period as short as 2 days was also sufficient to inhibit hepatic cholesterol synthesis. In both control and diabetic animals, fructose feeding decreased hepatic 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase activity but did not alter the percentage of HMG-CoA reductase in the active form. Finally, the intestinal hypertrophy and stimulation of intestinal cholesterogenesis that are characteristic of streptozotocin-induced diabetes occurred when either glucose or fructose was the sole caloric source.

Pitavastatin is a drug from the group of HMG-CoA reductase inhibitors, which has good lipid-lowering efficacy and has no significant effect on the risk of diabetes mellitus. This drug is non significantly metabolized by the P450 cytochrome system, which minimizes the risk of possible drug-drug interactions. Peptide organic anionic transporter inhibitors also may affect the efficacy and safety of the drug. This review summarizes the data on the problems of drug interactions of pitavastatin.
