Common cancer gene sends death order to tiny killer

... colleagues in Hopkins's department of medicine to put miR-34a into colon cancer cells. Doing this killed cells that contained p53, but fewer were killed in cells lacking p53, further suggesting that this microRNA gets its kill orders from p53. When researchers examined pancreatic cancer cells known t...

The insect vector always bites twice

...ected, vectors or non-vectors, were separated then put into contact with the serum of individual subjects, infected or uninfected, exposed to bites. Comparison of salivary protein immunogenic profiles obtained showed that they differ depending on the infection status of the subjects (exposed uninfected/i...

Studies to find better ways to preserve human eggs, ovarian tissue under way

In mice, drug protects against diabetes and atherosclerosis

...he drug or an inert substance. One set of mice was put on a high-fat "western" diet at five weeks of age; half received the inhibitor drug. A second group of animals ate the western diet for eight weeks, at which time they developed severe atherosclerosis. Then they were started on the drug to determine ...

Breakthrough developments in rheumatoid arthritis reported

...eases like rheumatoid arthritis, PTPN22 appears to put people at higher risk of a wayward T-cell response. The group has since gone on to use modern genetic methods to search for single nucleotide polymorphisms, or SNPs, to identify players that have fallen under the radar of older methods. The grou...

St. Jude study shows genes play an unexpected role in their own activation

...ing it and which signaling molecule caused cAMP to put CREB to work,” Brindle said. “It is another clue to how CREB might activate the genes for enzymes that make glucose in the liver, while activating different genes in the brain that are key to learning and forming memories.” A long-term implication...

'Smart' mice teach scientists about learning process, brain disorders

...said. "It’s been shown that it can be done, but we put the system together and actually applied it." Normally, Cdk5 works with another enzyme to break up a molecule called NR2B, which is found in nerve-cell membranes and stimulates the cell to fire when a nerve-cell-signaling molecule, or neurotransmi...

'Personality-gene' makes songbirds curious

... towards each of two unknown objects that had been put in its cage. One such novel object was a pink panther (see figure 2). The results from the group of selected birds were confirmed with data from free-living, unselected great tits. In the forest-living birds, the scientists also found a significa...

An ancient bathtub ring of mammoth fossils

...ific Northwest National Laboratory geologists have put out a call for teeth tusks, femurs and any and all other parts of extinct mammoths left by massive Ice Age floods in southeastern Washington. The fossils, in some cases whole skeletons of Mammathus columbi, the Columbian mammoth, were deposited in t...

Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...initiatives of our time. To recognize that what we put into our environment has potential pandemic effects on pregnancy outcome and possibly on child development is a momentous observation, which hopefully will help transform the way humanity cares for its world," said James Lemons, M.D., Hugh McK.

In their report, the authors note that the Sonso community had experienced a significant population increase in the ten years prior to the infanticide observations (42 individuals in 1996 to...

Chemical maps hint at drug's effects on schizophrenia
