The cytochrome P450 mixed function oxidase enzymes are the major catalysts involved in drug metabolism. There are many forms of P450. CYP2E1 metabolizes many toxicologically important compounds including ethanol and is active in generating reactive oxygen species. Since several of the contributions in the common theme series "Role of CYP2E1 and Oxidative/Nitrosative Stress in the Hepatotoxic Actions of Alcohol" discuss CYP2E1, this methodology review describes assays on how CYP2E1 catalytic activity and its induction by ethanol and other inducers can be measured using substrate probes such as the oxidation of para-nitrophenol to para-nitrocatechol and the oxidation of ethanol to acetaldehyde. Approaches to validate that a particular reaction e.g. oxidation of a drug or toxin is catalyzed by CYP2E1 or that induction of that reaction is due to induction of CYP2E1 are important and specific examples using inhibitors of CYP2E1, anti-CYP2E1 IgG or CYP2E1 knockout and knockin mice will be discussed.

Numerous studies reported about potential effects of L-carnosine in regulation of tumor growth and metabolism. We evaluated the effects of different concentrations of L-carnosine from supplement on mitochondrial respiratory chain complexes of human embryo lung fibroblasts (MRC-5) and human breast cancer cells (MCF-7), with different energy pathways. Also, we analyzed the proliferation index and expression of various markers of oxidative stress.

Background And Aims: Alcoholic liver disease (ALD) is the leading cause of death among alcohol-related diseases, yet its pathogenesis remains incompletely understood. This article employs data mining methods to conduct an indepth study of articles on ALD published in the past three decades, aiming to elucidate the pathogenesis of ALD.
Methods: Firstly, articles related to the pathogenesis of ALD were retrieved from the Web of Science (WOS) database.

Indoxyl sulfate (IS) has been implicated in the pathogenesis of cardiovascular diseases. IS is converted from indole, a metabolite of dietary tryptophan through the action of gut microbial tryptophanase, by two hepatic enzymes: CYP2E1 and SULT1A1. We hypothesized that the effect of tryptophan intake on IS production might differ from person to person.

The death rate due to liver cancer approaches 2 million annually, the majority is attributed to fibrosis. Currently, there is no efficient, safe, non-toxic, and anti-fibrotic drug available, suggesting room for better drug discovery. The current study aims to evaluate the anti-fibrotic role of reserpine, an alkaloid plant compound against CCl-induced liver fibrosis.
