Prostate cancer is one of the most common malignant neoplasms in men. Because of the increase in the number of cases as well as development of cancers resistant to conventional therapy, identification of the new molecular targets for the treatment and prevention is of great importance. For this purpose, many studies are aimed on revealing of molecular mechanisms of prostate cancer development. In this process, dietary lipids and environmental xenobiotics are largely involved and are considered as risk factors. A wide range of endogenous (cholesterol, polyunsaturated fatty acids, etc.) and exogenous (pollutants, drugs) compounds are metabolized in the human organism by cytochrome P450. From other hand, these compounds may alter cytochrome P450 expression levels, especially in prostate, which, in turn, affects cell metabolism. Cytochrome P450 is a member of signaling pathways, regulating cell cycle, apoptosis, invasion and adhesion. Hence, cytochrome P450 most probably plays the important role in initiation and progression of prostate cancer. Based on that, cytochrome P450 enzymes are considered as potential targets for the targeted therapy and prevention, and might serve as specific markers of malignant growth.

Biocatalytic oxyfunctionalization of unsaturated fatty acids to oxygenated chemicals via hydroxy fatty acids.
Biotechnol Adv

The selective oxyfunctionalization of unsaturated fatty acids is difficult in chemical reactions, whereas regio- and stereoselective oxyfunctionalization is often performed in biocatalytic synthesis. Fatty acid oxygenases, including hydratases, lipoxygenases, dioxygenases, diol synthases, cytochrome P450 monooxygenases, peroxygenases, and 12-hydroxylases, are used to convert C16 and C18 unsaturated fatty acids to diverse regio- and stereoselective mono-, di-, and trihydroxy fatty acids via selective oxyfunctionalization. The formed hydroxy fatty acids or hydroperoxy fatty acids are metabolized to industrially important oxygenated chemicals such as lactones, green leaf volatiles, and bioplastic monomers, including ω-hydroxy fatty acids, α,ω-dicarboxylic acids, and fatty alcohols, by biocatalysts.

Current studies found that the peritumoral tissue of hepatocellular carcinoma (HCC) may be different from normal liver tissue based on proteomics, and related to progression, recurrence and metastasis of HCC. Our previous study proposed "peritumor microenvironment (PME)" to summarize the influence of peritumor tissue on occurrence and progression of HCC. Peritumor CYP2E1 activity was significantly elevated in HCC, and related to occurrence and progression of HCC.

Co-metabolism with appropriate carbon sources has been demonstrated to effectively enhance the removal of ubiquitous recalcitrant micropollutant by microalgae. However, the specific impacts of carbon sources on the co-metabolism of antibiotics by microalgae remain insufficiently explored. In this study, transcriptomics, gene network analysis, extracellular polymeric substances (EPS), and enzymatic activity involved in co-metabolic pathways of norfloxacin (NFX), were systematically evaluated to investigate the underlying biological mechanisms involved in NFX co-metabolism by Chlorella pyrenoidosa.

Calcidiol (25(OH)VD) and calcitriol (1α,25(OH)VD) are active vitamin D with high medicinal value, which can maintain calcium and phosphorus balance and treat vitamin D deficiency. Microbial synthesis is an important method to produce high-value-added compounds. It can produce active vitamin D through the hydroxylation reaction of P450, which can reduce the traditional chemical synthesis steps, and greatly improve the production efficiency and economic benefits.

The bagrada bug, Bagrada hilaris (Burmeister), is an emerging agricultural pest in the Americas, threatening agricultural production in the southwestern United States, Mexico and Chile, as well as in the Old World (including Africa, South Asia and, more recently, Mediterranean areas of Europe). Substantive transcriptomic sequence resources for this damaging species would be beneficial towards understanding its capacity for developing insecticide resistance, identifying viruses that may be present throughout its population and identifying genes differentially expressed across life stages that could be exploited for biomolecular pesticide formulations. This study establishes B.
