Researchers at the Salk Institute have developed a new glioblastoma mouse model that closely resembles human brain tumors. The model uses modified viruses to shuttle cancer-causing oncogenes into adult mice, allowing scientists to study the development and progression of glioblastoma.
Researchers have discovered genetic markers associated with risk for ulcerative colitis, bringing them closer to understanding the biological pathways involved in the disease. The study's findings may lead to the development of new treatments specifically targeting these pathways.
Researchers at MIT have created a highly efficient method for pairing and fusing cells, which should facilitate the study of genetic reprogramming in hybrids. This innovation, led by Joel Voldman and Rudolf Jaenisch, improves upon existing cell fusion techniques by increasing the success rate to around 50%.
