RESUMEN

Dipeptidyl peptidase-4 inhibitor (DPP-4 inhibitor) such as sitagliptin has been presented as antidiabetic drugs and has numerous restorative advantages over different diseases; however, its defensive role against aflatoxin b1 (AFB1) liver toxicity has not been previously examined. Wistar rats (65 weeks, male) were utilized in the investigation. Animals were divided into five different groups (n = 10): control; AFB1; AFB1 + Sita (50); AFB1 + Sita (100); and Sita (100). Sitagliptin significantly (*p ≤ .05, **p ≤ .01, and ***p ≤ .001) altered the levels of various serum liver enzymes (lactate dehydrogenase, alkaline phosphate, aspartate aminotransferase, and alanine aminotransferase). It decreased the concentration of an oxidative stress marker, that is, malondialdehyde and increased the level of antioxidant enzymes such as reduced glutathione, catalase, superoxide dismutase, and glutathione peroxidase in AFB1-administered rats. It also improved the Nrf2 expression and HO-1 level in AFB1-intoxicated rats. This investigation discusses innovative evidence on the protective role of sitagliptin against AFB1-induced hepatotoxicity in rats.

RESUMEN

Hepatocellular carcinoma is the most common liver cancer among different types of cancers. Cordyceps Militaris mushroom species traditionally used as an alternative medicine in china for centuries. Gold nanoparticles plays vital role in the development of the anticancer drugs. In our research, we investigated the gold nanoparticles with C. Militaris on the hepatocellular carcinoma HepG2 cells. The synthesized gold nanoparticles stability and integrity was studied at different time intervals. The gold nanoparticles potentially halt the growth of the HepG2 cells at the IC50 concentration between 10 µg and 12.5 µg/ml. The HR-TEM and XRD revealed the size and shape of the synthesized gold nanoparticles. The size of the gold nanoparticles was about 15 20 nm and the shape of gold nanoparticles was face-center-cubic structure. The FT-IR results proved that the gold nanoparticles contain hydroxyl and alkynes groups. The gold nanoparticles extract develops ROS and cause damage to the mitochondrial membrane potential in the hepatocellular carcinoma HepG2 cells. The gold nanoparticles extract tends to initiate the apoptosis by activating the Bax, Bid, caspases and inhibits the activation anti-apoptotic bcl-2 in the HepG2 cells. Our results concluded that the gold nanoparticles with C. Militaris would be an efficient chemotherapeutic drug against the hepatocellular carcinoma cells.
