Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(12), P. 4852 - 4862

Inappropriate application of pesticides not only causes sub-lethal effects on ecosystem service providers but also reduces crop yield and quality. As a xenobiotic signal molecule, may interact with transduction receptors in crops, resulting oxidative damage even metabolic perturbations. We discovered that three neonicotinoid insecticides (NIs), namely, imidacloprid, thiamethoxam, clothianidin, at 0.06-0.12 kg ai/ha significantly inhibited the auxin pathway rice leaves, thereby reducing intracellular (IAA) content. Molecular simulation further confirmed NIs occupied binding site where transporter-like proteins 1 (LAX11) 2 (LAX12), which Thr253 Asn66 LAX11, as well Thr244 Asn57 LAX12, were bound to nitroguanidine via H-bonds. Meanwhile, LAX11 LAX12 interacted aromatic Moreover, phenylpropanoid biosynthesis was disturbed because pathway. Notably, peroxidase-coding genes downregulated maximum value greater than 10-fold, decreased antioxidant metabolites flavone (37.82%) lignin content (20.15%). Ultimately, biomass reduced by up 25.41% due decline IAA capacity. This study deeply explored molecular mechanism perturbations crops stressed pesticides, thus providing scientific basis for pesticide environmental risk assessment agricultural product safety.

DNA Methyltransferases: From Evolution to Clinical Applications

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(16), P. 8994 - 8994

Published: Aug. 12, 2022

DNA methylation is an epigenetic mark that living beings have used in different environments. The MTases family catalyzes methylation. This process conserved from archaea to eukaryotes, fertilization every stage of development, and the early stages cancer metastasis. DNMTs has been classified into DNMT1, DNMT2, DNMT3. Each DNMT duplicated or deleted, having consequences on structure cellular function, resulting a evolutionary reaction are five kingdoms life: bacteria, protists, fungi, plants, animals. importance whether methylate not historical adaptation mammals discovered complex regulatory mechanisms develop another padlock genomic insurance stability. control expression involved diversity cell phenotypes associated with pathologies transcription deregulation. work focused methyltransferases, their biology, functions, new inhibitory reported. We also discuss approaches inhibit DNMTs, use non-coding RNAs nucleoside chemical compounds recent studies, biological, clinical, industry research.

The role of UDP-glycosyltransferases in xenobioticresistance

Drug Metabolism Reviews, Journal Year: 2022, Volume and Issue: 54(3), P. 282 - 298

Published: May 28, 2022

Uridine diphosphate sugar-utilizing glycosyltransferases (UGTs) are an enzyme superfamily that catalyzes glycosyl residues transfer from activated nucleotide sugars to acceptor molecules. In addition various endogenous compounds, numerous xenobiotics substrates of UGTs. As the glycosides formed generally less active/toxic and more hydrophilic than aglycones, UGTs effectively protect organisms potentially harmful xenobiotics. Therefore, increased UGT expression and/or activity improve protection organism may contribute development individuals become resistant certain While function in resistance human cancer cells chemotherapy is now well known, other have attracted much attention. This review was designed fill this knowledge gap by presenting complex information about role xenobiotic-resistance organisms. summarization evaluation available reveals play important defense against not only humans, but countless such as parasites, insects, plants. Moreover, many recent studies clearly show participation nematodes anthelmintics, insects insecticides, weeds herbicides humans drugs (not those used therapy also treatment epilepsy, psychiatric disorders, hypertension, hypercholesterolemia, HIV infection). Nevertheless, although contribution xenobiotic diverse has obvious, pieces remain missing, for example with regard mechanisms regulation.

Erythromycin (ERY) is a typical macrolide antibiotic with large production and extensive use on global scale. Detection of ERY in both freshwaters coaster seawaters, as well relatively high ecotoxicity have been documented. Notably, hormesis has reported several freshwater algae under stress, where growth was promoted at lower exposures but inhibited higher treatment levels. On the contrary, there limited information toxicity marine algae, hampering risk assessment waters. The presence may challenge current concept dose-response adopted chemical assessment. Whether how exposure to can induce dose-dependent remain virtually unknown, especially environmentally relevant concentrations. present study used model diatom Thalassiosira weissflogii (T. weissflogii) reveal its toxicological responses different biological levels decipher underlying mechanisms.

Carboxylesterase and Cytochrome P450 Confer Metabolic Resistance Simultaneously to Azoxystrobin and Some Other Fungicides in Botrytis cinerea

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(17), P. 9680 - 9690

Published: April 18, 2024

Plant pathogens have frequently shown multidrug resistance (MDR) in the field, often linked to efflux and sometimes metabolism of fungicides. To investigate potential role metabolic B. cinerea strains showing MDR, azoxystrobin-sensitive strain B05.10 -resistant Bc242 were treated with azoxystrobin. The degradation half-life azoxystrobin (9.63 days) was shorter than that (28.88 days). Azoxystrobin acid, identified as a metabolite, exhibited significantly lower inhibition rates on colony conidia (9.34 11.98%, respectively) higher expression levels 34 cytochrome P450s (P450s) 11 carboxylesterase genes (CarEs) compared according RNA-seq analysis. P450 Bcin_02g01260 Bcin_12g06380, along CarEs Bcin_12g06360 Saccharomyces cerevisiae, resulted reduced sensitivity various fungicides, including azoxystrobin, kresoxim-methyl, pyraclostrobin, trifloxystrobin, iprodione, carbendazim. Thus, mechanism MDR is mediated by CarE genes.
