Mapping of Mouse Intestine Sheds Light on Immune Control and Adaptability

The intestine maintains a delicate balance in the body, absorbing nutrients and water while maintaining a healthy relationship with the gut microbiome, but this equilibrium is disrupted in parts of the intestine in conditions such as celiac disease, ulcerative colitis, and Crohn's disease.

Chromosome Abnormalities Found in Healthy Women’s Breast Cells

A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question conventional thinking on the genetic origins of breast cancer, which could influence early cancer detection methods.
