A $2.3 million network will investigate molecular mechanisms of rare diseases in yeast, worms, flies, fish, mice and humans. The goal is to understand disease mechanisms and identify therapeutic pathways for treatment.
A Tel Aviv University study found that reptiles with reduced reproductive rates and plant-rich diets lived longer than those with faster growth and early reproduction. Herbivorous reptiles consumed fewer calories and took a more leisurely pace, leading to increased longevity.
A new study reveals that long-used field inventory plots are not representative of tropical forests, leading to biased results. Advanced three-dimensional forest mapping techniques provide a more accurate understanding of forest structures and systems on large geographic scales.
A new study identifies Ewing sarcoma-associated transcript 1 (EWSAT1) as a critical target of the EWS-FLI1 fusion protein, contributing to cancer cell growth and repression of key genes. This finding supports the notion that long noncoding RNAs can drive cancer development and highlights an important mediator in Ewing Sarcoma.
Researchers at UT Southwestern Medical Center have identified over 3,000 new gene mutations involved in certain kidney cancers. The study reveals how these mutations transform a normal kidney cell into a cancer cell through the interaction of two genes, VHL and BAP1.
B cells use a unique migration strategy in the bone marrow that allows them to exit slowly and be passively swept out by blood flow. The researchers found that the absence of CXCR4 significantly slows down B cell movement, highlighting the importance of this protein in regulating immune cell egress.
