Transcription factor (TF) modules interact to regulate key biological processes and cell-state transitions in normal physiology and disease. Understanding these modules and how they evolve over time can be accomplished by constructing gene regulatory networks (GRNs). To identify context-specific TF subnetworks, we developed ChEA-KG, which generates enriched TF regulatory subnetworks for input gene sets. ChEA-KG is based on a GRN connecting 1559 human TFs via 131 181 signed and directed edges...

Researchers discovered that leucine, a nutrient found in protein-rich foods, can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. The breakthrough uncovers a powerful new link between diet and cellular energy — with possible implications for cancer and metabolic disease treatments.

A hearing would air questions about James O’Neill’s qualifications to lead the agency

MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged intestinal tissue after radiation exposure. Researchers say the discovery could eventually lead to new dietary therapies for cancer patients suffering from treatment-related gut damage.

Jeffery Taubenberger’s departure from a leadership position caps year of upheaval at National Institute of Allergy and Infectious Diseases

A better understanding of battles between bacteria and viruses could inspire new medicines

Odd phenomenon first seen in plants could explain puzzling disease inheritance patterns

Women may be especially sensitive to the effects of common dementia risk factors, according to a new UC San Diego study of over 17,000 adults. Researchers say tailoring prevention strategies specifically for women could be key to reducing Alzheimer’s risk.
