Preparation of gallic acid-loaded chitosan nanoparticles and their chemoprotective effects on N-ethyl-N-nitrosourea-induced hepatotoxicity and mortality in rats.

N-ethyl-N-nitrosourea (ENU) as n-nitrosamine and alkylating agent, ubiquitous within living cells and in the environment can act as a full carcinogen and induce tumor formation in various tissues such as liver. In this study, gallic acid-loaded chitosan nanoparticles (GANPs) were synthesized and evaluated for their chemopreventive effect against ENU-induced hepatotoxicity and mortality in rats. Twenty-four male Wistar rats were divided into four groups including: control, ENU (single doses of 50 mg/kg via intraperitoneal injection), GA + ENU and GANPs + ENU.

Pre-mating exposure with hesperidin protects N-ethyl-N-nitrosourea-induced neurotoxicity and congenital abnormalities in next generation of mice as a model of glioma.

Chemical carcinogen-induced oxidative stress has a key role in cell signaling linked to the development of cancer. Oxidative stress leads to oxidative damage to cellular membranes, proteins, chromosomes and genetic material. It is thought that compounds like hesperidin with high antioxidant and anticancer potential can reduce development of cancer induced by chemical carcinogens via neutralizing their oxidative damages.

Vitamin D ameliorates celecoxib cardiotoxicity in a doxorubicin heart failure rat model via enhancement of the antioxidant defense and minimizing mitochondrial dysfunction.

Recent evidence suggests the mechanistic role of mitochondria and oxidative stress in the development of celecoxib-induced cardiotoxicity. On the other, it has reported the positive effects of vitamin D on oxidative stress and the maintenance of mitochondrial functions. This current study examined the cardiac effects of celecoxib, doxorubicin, vitamin D, and a combination of them in rats.

Evaluation of in vitro effects of ifosfamide drug on mitochondrial functions using isolated mitochondria obtained from vital organs.

Mitochondrial toxicity has been shown to contribute to a variety of organ toxicities such as, brain, heart, kidney, and liver. Ifosfamide (IFO) as an anticancer drug, is associated with increased risk of neurotoxicity, cardiotoxicity nephrotoxicity, hepatotoxicity, and hemorrhagic cystitis. The aim of this study was to evaluate the direct effect of IFO on isolated mitochondria obtained from the rat brain, heart, kidney, and liver.

Chrysin ameliorates aluminum phosphide-induced oxidative stress and mitochondrial damages in rat cardiomyocytes and isolated mitochondria.

Apart from the anticancer, antioxidant, anti-inflammatory effects, and inhibition of aromatase, chrysin is involved in the protection of cardiovascular disorders. Cardiovascular complications are the main cause of death induced by aluminum phosphide (AlP) which is related to oxidative stress and mitochondrial damages. For this purpose, we investigated the effect of chrysin as an antioxidant and mitochondrial protective agent against AlP-induced toxicity in isolated cardiomyocytes and mitochondria obtained from rat heart ventricular.

Calcitriol Reduces Adverse Effects of Diclofenac on Mitochondrial Function in Isolated Rat Heart Mitochondria.

The safety of diclofenac (DIC) use in clinical practice has been questioned because of adverse cardiovascular effects. Previous studies have indicated that DIC cause mitochondrial dysfunction and oxidative stress in heart mitochondria. The aim of this study was to investigate the protective effect of calcitriol against the mitochondrial toxicity potency of diclofenac in heart rat mitochondria.
