Notch — the protein that can help determine cell fate — maintains a stable population of basal cells in the prostate through a positive feedback loop system with another key protein — TGF beta (transforming growth factor beta), said Baylor College of Medicine researchers in the journal Cell Stem Cell. "When basal cell homeostasis (or maintenance of a stable population) is disrupted, it may be part of the process that initiates prostate cancer," said Dr. Li Xin, assistant...

Scientists Learn How To Unlock The Destiny Of A Cell
2012-11-01 10:47:17

University of California - Santa Barbara Scientists have discovered that breaking a biological signaling system in an embryo allows them to change the destiny of a cell. The findings could lead to new ways of making replacement organs. The discovery was made in the laboratory of Joel H. Rothman, a professor in the Department of Molecular, Cellular, and Developmental Biology at UC Santa Barbara. The studies were reported in the interdisciplinary journal Genes and Development, and were...

Results may help improve drugs for neurological disorders Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs). "The knowledge of how the peptide binds to its receptor should help scientists design...

redOrbit Staff & Wire Reports - Your Universe Online Groundbreaking research into how the protein receptors of cells detect and respond to external signals -- work that could lead to the development of better drugs to combat cancer and diabetes -- has earned two US scientists the 2012 Nobel Prize in Chemistry. Sixty-nine year old Robert Lefkowitz, a professor at Duke University Medical Center, and 57-year-old Brian Kobilka, a professor at Stanford University School of Medicine, were...
