- Dietary simple sugars alter microbial ecology in the gut and promote colitis in mice
High-sugar diet promotes the growth of mucolytic bacteria, leading to reduction of the mucus layer and predisposition to colitis in mice.
- Mohawk is a transcription factor that promotes meniscus cell phenotype and tissue repair and reduces osteoarthritis severity
Mohawk is enriched in meniscal tissue and promotes meniscus cell phenotype, enhances repair, and protects against cartilage destruction in mice.

About The Cover

ONLINE COVER Low Sugar for a Healthy Gut. This image shows mucin (green) and intestinal bacteria (red) in a section of colon tissue from a mouse fed a high-sugar diet. A Western diet, characterized by elevated sugar content, is associated with higher incidence of inflammatory bowel disease (IBD). Studying the link between sugar and IBD, Khan et al. fed mice either a standard diet or a high-sugar diet before inducing colonic inflammation. Animals fed a high-sugar diet developed more severe disease due to alterations in the gut microbiome. High-sugar diet promoted the growth of mucus-degrading bacteria that facilitated intestinal barrier damage. The results suggest that sugar might play a major role in triggering IBD.
