Researchers created mice lacking SHIP gene to understand how bone forms and breaks down in diseases like JPD. The study reveals that mice with deficient SHIP develop osteoclasts similar to those found in humans with JPD, leading to severely osteoporotic conditions.
A physical map of the mouse genome provides detailed organization and context to the draft sequence, aiding in gene discovery and understanding health and disease. This mapping effort also enables researchers to access specific regions of DNA for further study.
The Karnal bunt pathogen faces challenges in reproducing over long distances, leading to declining small populations instead of growth. Researchers found that a critical mass is needed for the population to function well and invade new areas.
