Complex gene interactions account for autism risk

...sm, there remains no single gene with a consistent connection to the disease, Pericak-Vance said. Multiple lines of evidence, including alterations in levels of GABA and GABA receptors in patients with autism, have implicated the brain mechanism in the disease. Furthermore, there is evidence that GABA plays a ...

Asian immigrants in NYC not receiving HIV education at religious institutions

...immigrants for whom a temple or mosque is the only connection with a formal support system and therefore a potentially critical source of life-saving health information, said lead author John J. Chin, Ph.D., Senior Research Associate in the Academy Division of Health Policy. "Religious institutions in Asian im...

'License to kill' enables powerful immune attack cells in mice

... licensing." Their results include another ironic connection to the world of cinema spies: the molecular details of the process feature a player who is comparable to a double agent. Scientists have known for some time that natural killer cells have inhibitory receptors on their surfaces. The natural killer ce...

Color perception is not in the eye of the beholder: It's in the brain

... tests on the original volunteers showed no simple connection among certain genes and the number and diversity of color cones, but Williams is continuing to search for the responsible combination of genes. ...

A 'dimmer switch' for genes

...as in the case of cancer, grow out of control. The connection between factors such as Ets-1 and a number of cancers prompted the study of how it works. One way proteins are controlled occurs after a cell creates a protein. Graves illustrates this process by comparing protein structure with beads on a string. "...

Newly recognized gene mutation may reduce seeds, resurrect plants

... (RST1), has revealed a previously unknown genetic connection between lipid development and embryo development in plants, said Matthew Jenks, lead author of the study and a Purdue plant physiologist. Lipids play a role in preventing plant dehydration in forming cells' membranes, in molecular signaling and in e...

Molecular Partners Required For Appropriate Neuronal Gene Repression

...tudying another mouse model in my lab, we made the connection between heightened levels of HA -- specifically a high-molecular weight version of HA -- and myelin loss in an MS-like disease in mice. We also identified the cells that were making the HA and determined that HA accumulation was linked to an overabun...

"I think what it will show is that the replanting that almost everybody does in (tropical regions) is an extremely inefficient ...

Scientists create digital bacteria to forge advances in biomedical research

...goal in single-cell biology today: to document the connection between internal biochemical fluctuations and cellular behavior. "The belief is that these fluctuations are going to be reflected in the behavior of the cell as shown experimentally by John Spudich and Daniel Koshland in 1976," Emonet said. They may ...

Rodent social behavior encoded in junk DNA

...m spectrum disorders are characterized, a stronger connection may emerge. Far from being junk, the repetitive DNA sequences, which are highly prone to mutate rapidly, may ultimately exert their influence through complex interactions with other genes to produce individual differences and social diversity, accor...

Physical and functional interaction of key cell growth molecules linked to cancer

... malignancies, there has previously been no direct connection made between EGFR and the iNOS/NO pathway. The researchers conclude that the complex formed by EGFR and STAT3 can directly regulate gene expression and provides a new transcriptional mechanism that may play a significant role in human cancers, trans...
