A review on the use of extracellular vesicles for the delivery of drugs and biological therapeutics.

Introduction: Exosomes, a type of extracellular vesicles, are effective tools for delivering small-molecule drugs and biological therapeutics into cells and tissues. Surface modifications with targeting ligands ensure precise delivery to specific cells, minimizing accumulation in healthy organs and reducing the side effects. This is a rapidly growing area in drug delivery research and this review aims to comprehensively discuss the recent advances in the field.

Dietary phytochemical and metabolic disease prevention: Focus on plant proteins.

Plant-based functional foods have attracted increasing research interest to validate their use in preventing metabolic disease. Since it is increasingly recognized that inflammation, oxidative stress, and circadian rhythm play vital roles in various metabolic diseases, including diabetes, obesity and non-alcoholic liver disease, plant proteins, protein hydrolysates, and food extracts that intervene in these biological processes are promising dietary supplements to prevent metabolic diseases. Here, we reviewed the recent research on plant-based foods used for metabolic disease prevention and provided new perspectives regarding the current study gaps and future directions in this field.

Irinotecan decreases intestinal UDP-glucuronosyltransferase (UGT) 1A1 via TLR4/MyD88 pathway prior to the onset of diarrhea.

Irinotecan is a first-line treatment for colorectal cancer and the prodrug of 7-ethyl-10-hydroxy-camptothecin (SN-38). However, its fatal gastrointestinal (GI) toxicity raises serious concern. In liver, irinotecan generates its inactive metabolite, SN-38G via UDP-glucuronosyltransferase (UGT)1A1.

Neratinib causes non-recoverable gut injury and reduces intestinal cytochrome P450 3A enzyme in mice.

Neratinib is a pan-HER tyrosine kinase inhibitor newly approved by FDA in 2017 to treat HER2-positive breast cancer, but the phase III trial of neratinib showed that 96% of the patients taking neratinib experienced diarrhea. So far very few mechanistic studies explore neratinib-induced gastrointestinal (GI) toxicity. Hereby, we performed toxicity studies in mice to characterize the potential mechanism underlying this adverse effect.
