A crucial reaction in harnessing renewable carbon from lignin is -demethylation. We demonstrate the selective -demethylation of syringol and guaiacol using different cytochrome P450 enzymes. These can efficiently use hydrogen peroxide which, when compared to nicotinamide cofactor-dependent monooxygenases and synthetic methods, allows for cheap and clean -demethylation of lignin-derived aromatics.

Sitobion miscanthi is a wheat aphid species that can damage seriously agricultural production. The effective management of wheat aphids has depended on chemical insecticides. However, their wide application led to severe resistance of wheat aphids to some insecticides, and cytochrome P450 as a detoxifying enzyme plays a crucial role in the insecticide resistance.

Widespread anthelmintic resistance has complicated the management of parasitic nematodes. Resistance to the benzimidazole (BZ) drug class is nearly ubiquitous in many species and is associated with mutations in beta-tubulin genes. However, mutations in beta-tubulin alone do not fully explain all BZ resistance.

Obesity exacerbates the risk and aggressiveness of many types of cancer. Adipose tissue (AT) represents a prevalent component of the tumor microenvironment (TME) and contributes to cancer development and progression. Reciprocal communication between cancer and adipose cells leads to the generation of cancer-associated adipocytes (CAAs), which in turn foster tumor invasiveness by producing paracrine metabolites, adipocytokines, and growth factors.

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.

Lactacystin is an irreversible proteasome inhibitor isolated from Streptomyces lactacystinicus. Despite its importance for its biological activity, the biosynthesis of lactacystin remains unknown. In this study, we identified the lactacystin biosynthetic gene cluster by gene disruption and heterologous expression experiments.
