Microbes affect drug responses, but mechanisms remain elusive. Two papers in Cell exploit C. elegans to infer anticancer drug mechanisms. Through high-throughput screens of drug-microbe-host interactions, García-González et al. (2017) and Scott et al. (2017) determine that bacterial metabolism underpins fluoropyrimidine cytotoxicity, providing a paradigm for unraveling bacterial mechanisms in drug...
In short bowel syndrome, luminal factors influence adaptation in which the truncated intestine increases villus lengths and crypt depths to increase nutrient absorption. No study has evaluated the effect of adaptation within the distal intestine after intestinal separation. We evaluated multiple conditions, including Igf1r inhibition, in proximal and distal segments after intestinal resection to evaluate...
The intestinal microbiota influence neurodevelopment, modulate behavior, and contribute to neurological disorders. However, a functional link between gut bacteria and neurodegenerative diseases remains unexplored. Synucleinopathies are characterized by aggregation of the protein α-synuclein (αSyn), often resulting in motor dysfunction as exemplified by Parkinson’s disease (PD). Using mice that overexpress...
The pediatric intestinal microbiome is impacted by many factors, including age, diet, antibiotics, and environment. We hypothesized that in operative patients, alterations to antibiotics and mechanoluminal stimulation would demonstrate measurable changes in the intestinal microbiome and that microbial diversity would be reduced without normal mechanoluminal stimulation and with prolonged antibiotic...
