Based on the optimization of the upstream SD regions and culture medium, the yield of the strain EDW11 reached a high level during microbial lycopene production until now.
arsenic trioxide (aTo) is a frontline chemotherapy drug used in the therapy of acute promyelocytic leukemia. However, the clinical use of aTo is hindered by its cardiotoxicity. The present study aimed to observe the potential effects and underlying mechanisms of tannic acid (Ta) against aTo-induced cardiotoxicity. Male rats were intraperitoneally injected with aTo (5 mg/kg/day) to induce cardiotoxicity. Ta (20 and 40 mg/kg/day) was administered to evaluate its cardioprotective efficacy against ATO-induced heart injury in rats. administration of aTo resulted in pathological damage in the heart and increased oxidative stress as well as levels of serum cardiac biomarkers creatine kinase and lactate dehydrogenase and the inflammatory marker NF-κB (p65). conversely, Ta markedly reversed this phenomenon. additionally, Ta treatment caused a notable decrease in the expression levels of cleaved caspase-3/caspase-3, Bax, p53 and Bad, while increasing Bcl-2 expression levels. notably, the application of Ta decreased the expression levels of cytochrome c, second mitochondria-derived activator of caspases and high-temperature requirement a2, which are apoptosis mitochondrial-associated proteins. The present findings indicated that Ta protected against aTo-induced cardiotoxicity, which may be associated with oxidative stress, inflammation and mitochondrial apoptosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
