Circadian Rhythm Disrupts Gut Barrier in Cancer

Research from the University of California, Irvine has revealed how disruption of the circadian clock, the body's internal, 24-hour biological pacemaker, may accelerate the progression of colorectal cancer by affecting the gut microbiome and intestinal barrier function. This discovery offers new avenues for prevention and treatment strategies.

AI-Driven Insights into Lasso Peptide Biosynthesis

Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tested models for how these peptides are made and demonstrated how this information might be used to advance lasso peptide-based drugs into the clinic.

Harnessing the Power of Beneficial Bacteria to Fight Enterobacteriaceae

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enterobacteriaceae are a common cause of these infections and have few treatment options. Fecal microbiota transplants have shown promise to curb some of these infections, but their composition varies between batches and they aren't always successful.
