A gene's first 'kiss' sets off that affair known as puberty

... on by a molecule that is produced by a gene aptly named KiSS-1. The couple ?a biochemical equivalent to Adam and Eve ?makes its sudden appearance in a region of the brain called the hypothalamus just as puberty begins, according to a study published in this week's online edition of the Proceedings of the...

Newly-discovered class of genes determines ?and restricts ?stem cell fate

...breaks on differentiation," says Epstein. "We have named them pangenes, after the Greek god Pan and Peter Pan, who were able to orchestrate complex events while never growing old." Epstein thinks that this concept may also be important for understanding the cell of origin for a number of tumors. Pax3 is k...

Scientists detect probable genetic cause of some Parkinson's disease cases

...tly discovered LRRK2, a gene thatencodes a protein named dardarin by the researchers from the Basqueword dardara, which means tremor, a major symptom of Parkinson'sdisease. It was isolated on a region of chromosome 12 called PARK8 byinvestigators who studied five families with a history of Parkinson'sdisea...

U of M researcher examines newly emerging deadly disease

...innesota have identified a newly emerging illness, named staphylococcal purpura fulminans. The disease begins as a respiratory tract infection, which then is infected by Staphylococcus aureus. The infection then moves to the lungs, making superantigens (bacterial toxins that activate large numbers of T cel...

Leukemia Drug Breakthrough Study In New England Journal Of Medicine

... of the MDS patients with a chromosome abnormality named 5q minus syndrome became transfusion independent. The defective 5q chromosome abnormality may be linked to other serious cancers, including leukemias and small cell lung cancer. In another finding of the same study, all the patients with the 5q dele...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

...ted to stop allergic reactions. The investigators named the chimeric molecule GFD, or gamma Feline domesticus, for its human and feline parts, explains principal investigator Andrew Saxon, M.D., of UCLA. The cat allergen end of GFD binds to antibodies on the surface of the cell. The human end of GFD links...

In the sea slug's defense against lobsters, confusion is key

...e activation of a feeding pathway, the researchers named this novel chemical defense "phagomimicry." The stickiness of the slug's secretions appears to contribute to long-lasting effects on the target despite the aqueous environment, enhancing the effectiveness of the slug's defense. Cynthia E. Kicklighte...

Researchers trace evolution to relatively simple genetic changes

...The gene they identified is called Eda, originally named after a human genetic disorder associated with the ectodysplasin pathway, an important part of the embryonic development process. The human disorder, one of the earliest ones studied, is called ectodermal dysplasia. "It's a famous old syndrome," Kin...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

Scientists document complex genomic events leading to the birth of new genes

...nning approximately 10% of human chromosome 2, was named RGP (for RanBP2-like, GRIP domain-containing proteins). By analyzing the gene order around the RanBP2 and GCC2 genes, Bork's team was able to reconstruct the genomic rearrangements leading to the formation of the ancestral RGP locus. These events in...

Wisconsin researchers identify sleep gene

...rough a series of tests, the short-sleeping flies, named minisleep (mns), were found to perform normally and did not appear to be impaired by sleep deprivation. The mns flies, however, did have shorter life spans. Following the testing, the researchers noticed shaking in the flies' legs as the insects rec...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...P project began in 2003 when a solar-powered robot named Hyperion, also developed at Carnegie Mellon, was taken to the Atacama as a research test bed. Scientists conducted experiments with Hyperion to determine the optimum design, software and instrumentation for a robot that would be used in more extensiv...

New winter hulless barley has high protein

"Similar to wheat in appearance, ulless barley is significantly higher in starch content ...

Increased risk of osteoporosis associated with gene that one in five people have

...eral Research and is available online. The gene, named CYP1A1, makes an abundant enzyme that detoxifies foreign substances and also breaks down estrogen as a normal part of maintaining proper estrogen balance. Within the general population, several variations of the CYP1A1 gene exist, and the variants di...

A puzzle piece found in unraveling the wiring of the brain

...t fly, Drs. Sunil Mehta and Hiesinger found a gene named sec15 that is required for nerve cells to make appropriate choices of targets on which to act. The Sec15 protein is part of a protein complex (the exocyst) which is known to be required for secretion (or exocytosis) of vesicular compartments in yeas...
