The goal is to determine how many double-strand breaks (DSBs) in which both strands of the DNA double helix are severed occur per gray of radiation.

The protein produced by HTR2A acts as a receptor on brain cells for the chemical messenger serotonin, one of several neurotransmitters that enable the cells to communicate with each other. The discovery that a variation in a serotonin-related gene could affect response t...Phase II study of therapeutic vaccine shows efficacy in patients with metastatic colorectal cancer
... protein is rarely found in normal tissues, but is produced at high levels by a wide range of human cancers, including colorectal, renal, gastric and ovarian. The production of 5T4 has been associated with cancer metastasis and poor prognosis for patients. Typically, the immune system doesnt pay attention ...Handicapping tuberculosis may be the way to a better vaccine
...investigator William R. Jacobs and colleagues have produced a genetically altered strain of tuberculosis (TB) that elicits a stronger immune response than the current vaccine, bacillus Calmette-Gurin (BCG). The new vaccine improves survival of infected animals and may help put scientists on track to replace B...New grants bolster efforts to generate faster and cheaper tools for DNA sequencing
