Mutant mouse provides insights into breast cancer

...y in some form or another," said John Schimenti, a genetics professor in Cornell's Departments of Biomedical Sciences, and Molecular Biology and Genetics and the paper's senior author. "Our research demonstrated that genomic instability is probably leading to these cancers." Schimenti and colleagues found t...

LSU professor discovers new species

...said Austin. He used the cutting-edge molecular genetics lab at the LSUMNS to decipher the genetic code of the lizards. "We sequenced the DNA of this new species and several other closely related species in order to help our diagnosis," he said. "Using DNA to help describe new species is becoming one of th...

Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals

...dy c-author Jonathan Pritchard, professor of human genetics who led the University of Chicago team that analyzed the sequencing data. "If we can compare humans and Neanderthals genomes, then we can possibly identify what the key genetic changes were during that final stage of human evolution." Another autho...

U of S Vaccine and Infectious Disease Organization team discovers key step in flu virus replication

...lling pathways. To do this, they are using reverse genetics technology, where researchers begin with a gene and figure out its function. These studies will allow the team to identify the genes that enable the virus to cause disease, laying the groundwork for antiviral drug development. "Increasingly, n...

Newly discovered behavior in cancer cells signals dangerous metastasis

...Garcia-Blanco, M.D., Ph.D., professor of molecular genetics and microbiology. The researchers will publish their findings in the Sept. 19, 2006, issue of the journal Proceedings of the National Academy of Sciences, now available on line. The research was funded by the National Cancer Institute. Until now, s...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...ne that can't be predicted by current knowledge of genetics and physiology. "It appears from our study that dopamine acts as an interface between stress, pain and emotions, or between physical and emotional events, and that it's activated with both positive and negative stimuli," says senior author Jon-Ka...

A new male-specific gene in algae unveils an origin of male and female

By studying the genetics of two closely related species of green algae that practice different forms of sexual reproduction, researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells. The findings...

Fruit fly aggression studies have relevance to humans, animals

... Researchers in the North Carolina Sate University genetics department have identified a suite of genes that affect aggression in the fruit fly Drosophila melanogaster, pointing to new mechanisms that could contribute to abnormal aggression in humans and other animals. The study, led by doctoral student Ale...

Blue eyes -- A clue to paternity

...ion of paternity, based on eye color. The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. If both parents have brown eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. The brow...
