Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture.
The goal of every dividing cell is to accurately segregate its genome into two genetically identical daughter cells. However, this process often goes awry and may be responsible for a new class of chromosomal abnormalities found in cancers and congenital disorders, UT Southwestern Medical Center scientists report in a new study. The discovery, published in Nature, sheds light on how cancer cells rapidly evolve genomic changes that fuel their proliferation.
In medicine and science, the term “pathogenesis” describes the origin and development of disease. There is not, however, a broadly accepted term to describe the other half of the equation: the process of healing and recovery.

Cell membrane protrusions called blebs that typically signify the end of life for healthy cells do the opposite for melanoma cells, activating processes in these cells that help them to survive and spread, a UT Southwestern study suggests.
Virginia Tech professor Robert Gourdie says teamwork is an important element in the process of discovery, and it involves many teams full of talented, curious, and lively people.
