Summary: Two oat genes orthologous to a barley gene associated with resistance to Fusarium were identified and characterized. These genes showed high inducibility by DON and Fusarium infection. Heterologous expression of these genes in yeast conferred resistance to multiple trichothecene mycotoxins. Recombinant enzymes derived from these genes were able to convert DON into DON-3-O-glucoside.

Summary: UDP-glycosyltransferases (UGTs) are important enzymes in biotransformation, controlling the levels and distribution of signaling molecules and the metabolism of various chemicals. The UGT superfamily includes UGT1, UGT2, UGT3, and UGT8 families. UGTs play a role in tumor cell metabolism, affecting cancer development and prognosis. This review summarizes the roles of UGT enzyme families in tumor function, metabolism, and regulatory mechanisms, including their inhibitors and inducers. The function of UGTs in lipid metabolism, drug metabolism, and hormone metabolism in tumor cells is highlighted.

Summary: The UDP-glycosyltransferase (UGT) superfamily plays a critical role in the metabolism of anticancer drugs and pro/anti-cancer molecules. A comprehensive analysis of 10,069 tumors from 33 different types of cancers revealed widespread somatic mutations in UGT genes, which may impact the ability of cancer cells to metabolize drugs and endobiotics involved in cancer signaling pathways.

Summary: Drug-drug interactions (DDIs) involving glucuronidated drugs have been historically overlooked but are clinically significant and can result in altered exposure of these drugs. This review examines the mechanisms, scope, and aetiology of these DDIs, including the inhibition and induction of UDPglucuronosyltransferase (UGT) enzymes and the potential involvement of drug transporters. It highlights the common occurrence and importance of UGT induction as a DDI mechanism and the need for dose individualisation due to clinically relevant DDIs. Comprehensive reaction phenotyping studies and rigorous assessment of new chemical entities with significant glucuronidation are recommended for early-stage drug development.

Summary: The study discovered the presence of native 2,4-dihydroxybenzoic acid (2,4-DHBA) and its glycosylated form in tea plants, and found that their accumulation is induced by salicylic acid (SA) application and Ps. camelliae-sinensis (Pcs) infection. The regulation of 2,4-DHBA glycosylation positively affects disease resistance in tea plants.

Summary: UDP-glucosyltransferase can be coupled with sucrose synthase to construct a two-enzyme UDP recycling system for glucosylation of natural products. However, sucrose hydrolysis leads to the accumulation of fructose as a byproduct, which decreases the atom economy of sucrose and suppresses in situ UDP recycling. In this study, a polyphosphate-dependent glucokinase was demonstrated to convert fructose to fructose-6-phosphate independent of expensive ATP for the first time. Then the glucokinase was introduced into the UDP recycling system to construct a modified three-enzyme UDP recycling system, which showed enhanced glucosylation efficiency of triterpenoids by fructose phosphorylation to accelerate sucrose hydrolysis and UDP recycling. Finally, by further introducing a phosphofructokinase into the UDP recycling system, we transformed fructose-6-phosphate into fructose-1,6-diphosphate, demonstrating that the UDP recycling system can be coupled with extra enzymes to obtain final products with high added-value without compromising the glycosylation efficiency.

Summary: Inflammatory bowel disease (IBD) is a chronic inflammatory disease characterized by excessive activation of T cells. This study investigated the involvement of glycosphingolipids (GSLs) in IBD. The results showed that decreased expression of UDPglucose ceramide glucosyltransferase (UGCG), a GSLs synthase, was associated with IBD. Decreased UGCG led to worsened colitis and lower levels of regulatory T cells (Treg). Additionally, treatment with glucosylceramide (GlcCer) nanoparticles showed potential efficacy in preventing DSS-induced colitis, suggesting GlcCer in T cells as a therapeutic target for IBD patients.

Summary: This study found that UGCG gene is significantly upregulated in venous malformation patients, and UGCG may be involved in the pathogenesis of venous malformation by promoting the proliferation, migration, and tube formation of vascular endothelial cells. In addition, UGCG regulates the AKT/mTOR signaling pathway, which might be a potential mechanism underlying venous malformation.

Summary: Salicylic acid (SA) plays a crucial role in regulating disease resistance in plants, including rice. A newly identified UDP-glucosyltransferase gene, UGT74J1, was found to control SA homeostasis in rice. Mutants of UGT74J1 exhibited increased resistance against rice blast while showing stunted growth phenotypes, providing valuable insights into SA-mediated immunity in rice.

Summary: The study identified and analyzed a total of 107 UGTs in the L. polystachyus transcriptome, including four candidate genes involved in phlorizin synthesis and three candidate genes involved in trilobatin synthesis. The functions of these candidate genes were expressed and validated in vitro, and the results showed differences in activity and catalytic efficiency. The molecular docking analysis suggested that these differences may be caused by variations in the efficiency of the LpUGT proteins in catalyzing sugar donor protonation.

Summary: The gastrointestinal side effects of donepezil are common in patients, occurring in 20-30% of cases. Experimental studies in pigs showed that intestinal injury and prolonged transit time led to higher plasma concentrations of donepezil, highlighting the importance of dose adjustment in patients with underlying gastrointestinal diseases. Additionally, donepezil had a negative impact on gastric myoelectric activity, especially when combined with intestinal injury, which may explain the dyspepsia associated with the medication in humans.

Summary: The control of strongylid infections in horses has become challenging due to anthelmintic resistance. This study in the Czech Republic evaluated the efficacy of different anthelmintics and found total failure of fenbendazole and reduced efficacy of pyrantel embonate. Ivermectin and moxidectin exhibited excellent efficacy. The findings highlight the need for advanced parasite control approaches to slow the spread of anthelmintic resistance.

Summary: Our study investigated the effects of feeding sainfoin pellets on ruminal fermentation and microbiome, hematological profile, and abomasal histopathology in lambs infected with gastrointestinal nematodes. The results showed that lambs fed sainfoin had lower populations of specific bacteria in the rumen and lower methane concentrations. There was also an increase in the abundance of a specific bacteria species. In addition, the infection of gastrointestinal nematodes affected the number of red blood cells in the lambs and led to more damaged abomasal glands.
