Researchers reconstruct parts of the genome of a common mammalian ancestor

... work. According to Rasmus Nielsen, a geneticist at Cornell University who is familiar with the work, the paper is guaranteed to turn heads. "Previously it was thought that we would never really know what our ancestors looked like at the genetic level, but now it appears that we'll be able to tell,...

Scientists uncover clues to the mystery of 'gene deserts'

...ng diseases." JGI Director Eddy Rubin, a geneticist and physician who led the earlier studies indicating the presence of both functioning and non-functioning gene deserts, agreed: "If you're a gene hunter looking for genetic clues to diseases," he said, "it might be a good idea to steer clear of regio...

Chicken genome analysis unlocks secrets of mammalian and bird evolution

The researchers identified part of the molecular pathway that may help explain this reduction in mature macrophages: Cells carry a...

New genetic mutation linked to Parkinson's disease

... patients is pretty dramatic," said Dr. Nichols, a geneticist at the Cincinnati medical center. The LRRK2 gene, which is on a region of chromosome 12 called PARK8, is one of five Parkinson's disease genes in which mutations have been identified. LRRK2 was isolated by Andrew Singleton, Ph.D., of the National Ins...

"More important, because the Pokemon protein plays such a crucial role in the formation of cancer, it could prove to be an effective target for new drug therapies." Pokemon works by contro...

Hypertension risk in African-Americans linked to genetics, Stanford study finds

The study by Risch, Xiaofeng Zhu, PhD, at Loyola University Medical Center, and other colleagues is published in the Jan. 23 online issue of Nature Genetics. The study examined people...

Children's taste sensitivity and food choices influenced by taste gene

...ns of AA children. According to study co-author, geneticist Danielle Reed, PhD, "The children most sensitive to PROP liked sweet more, but the reason for this relationship is not known. This difference could be due to taste receptor biology or it could be because those who are most bitter sensitive use more...

HHMI professor, 138 undergraduates identify essential genes in eye formation

...hich is Banerjee's research focus. "The only way a geneticist can ask that question is to mutate that gene and see what happens to the eye," Banerjee explained. "The problem is, if you mutate that gene, the fly is dead as an embryo. What has to be done, he said, is to "make the eye mutant without making the res...

Scientists will discuss remarkable advances in whale research at the annual meeting of AAAS

...arctic minke whales. It turns out that New Zealand geneticist Scott Baker conducted an independent analysis of minke whale DNA using both the D loop gene and another mitochondrial gene called cytochrome b. ''We wanted to see if cytochrome b-a different gene with much nicer mutational characteristics than D loop...

The findings may have implications for other diseases as well. "Chromosome 22q11.2 deletion syndrome is one of a number of con...

Researchers trace evolution to relatively simple genetic changes

...new animal types evolve in nature," said molecular geneticist David M. Kingsley, a Howard Hughes Medical Institute investigator at the Stanford University School of Medicine. "People have been interested in whether a few genes are involved, or whether changes in many different genes are required to produce majo...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

... the efficacy of the treatment," said Duke medical geneticist Dwight Koeberl, M.D., senior author of the study. "By restricting the expression of introduced genes to muscle, the immune response can be prevented or attenuated." The muscle-targeted gene therapy might therefore apply to other forms of muscular dys...

Friedman, M.D., Ph.D., a molecular geneticist whose discovery of the hormone leptin and its role in regulating body weight has changed our understanding of the causes of human obesity, has received two prestigious awards for this work: the Gairdner Foundation International Award and the Passano ...

Reducing specific gene levels makes breast cancer cells more responsive to ionizing radiation

...Chase postdoctoral researcher in the laboratory of geneticist Andrew K. Godwin, Ph.D., and the study's lead author. Working with breast-cancer cell line MCF-7, the Fox Chase scientists reduced BRCC36 expression by 80 percent. They then exposed the cells to radiation, similar to that used in breast cancer treat...
