In the rats that roam New York City’s streets and tunnels, scientists have found a virus that resembles hepatitis C. They have used it to create the first animal model of the human disease, a breakthrough that potentially could yield a much-needed vaccine.
Allis has received the March of Dimes Prize in Developmental Biology. The award, given to investigators whose research offers hope for the prevention and treatment of birth defects and other infant diseases, honors Allis for his groundbreaking work on gene regulation.
Scientists have long seen parallels between healing wounds and growing tumors. In studying the molecular changes that occur within both, a research team has discovered a new cancer-fuelling mechanism that potentially could inform drug development.
Researchers have identified a molecule that guides the formation of eggs and sperm by preventing a host of factors related to cell death and inflammation from killing the precursors to these cells. Their findings reveal new knowledge about how a mutation in this molecule leads to male sterility.
Some viruses can insert their genetic material into the genome of their host, creating a genetic fossil record. Researchers have uncovered how our ancestors may have wiped out one such virus around 11 million years ago.
The centromere region of chromosomes retains the same DNA from one generation to the next. Scientists have gained new insights into how it avoids being scrambled in normal cells, and how it becomes unstable in cancer.
Scientists have discovered a common mutation that might explain why some people have trouble going to sleep at night and getting up early. The gene alteration slows the internal biological clock that regulates our sleeping patterns.
