Researchers report new gene test for isolated cleft lip and palate

...efts arise during fetal development from a dynamic interplay of genes, diet, and environmental factors, and current research tools are just beginning to cut through the complexity. Though the condition is usually correctable with several surgeries, families undergo tremendous emotional and economic hardship du...

Researchers report new gene test for isolated cleft lip and palate

...lopment from a dynamic and still poorly understood interplay of genes, diet, and environmental factors, and current research tools cannot adequately cut through the complexity. One productive inroad has been to isolate genes linked to "syndromic" cleft lip and palate, hoping some might also play a role in ca...

UCSD researchers are first to demonstrate molecular link between inflammation and cancer

...r Center. "In response to chronic infection, the interplay between immune cells and the epithelial cells of the intestinal tract, which become genetically transformed to give rise to malignant cells by the carcinogen, results in increased tumor growth and suppression of apoptosis, whose role is to reduce can...

Yale scientists visualize details of how hepatitis C unwinds RNA

...composition of the HCV replication complex and the interplay between its constituent proteins. Comparative studies will be done on other viruses and in other systems where helicase function is critical." These novel features were revealed using a new type of combinatorial enzymology that allows the behavior of...

Carnegie Mellon neuroscientist develops tool to image brain function at the cellular level

...e changes are hypothesized to be part of a dynamic interplay between forces that maintain neural firing within an optimal range and those that strengthen particular connections between cells, thought to underlie learning," Barth said. The fosGFP mouse is a broadly applicable tool for many neuroscientists, acco...

Study reveals evolution on the (butterfly) wing

...wing patterns dramatically exemplify the intricate interplay between genes and the environment -- as the patterns evolve to give butterflies advantages in evading predators and attracting mates. In a paper in the July 13, 2004, issue of Current Biology, biologists Robert Reed and Michael Serfas add a new piece...

UC Riverside researchers discover new way to identify cell growth

...l cycle. So any advance in recognizing the complex interplay of proteins that control and regulate the cell cycle has relevance for the diagnosis and treatment of cancer. Sauer said that he and his colleagues have celebrated the result of a long research effort. "We had a very nice bottle of Champagne. Yes, t...

Artificial light-dark cycles expose circadian clocks at odds with each other

... night hours, and that enabled them to look at the interplay of two genes in the rats' brain clocks. One gene, called Per1, is active during the day and the other, Bmal1, is active at night. The scientists found that when a rat behaved as expected, its suprachiasmatic nucleus contained Per1 during light perio...

Wisconsin chemists find a new chink in TB's armor

...lso gives it a new biological role. Detailing the interplay between vitamin B2 and the enzyme provides a blueprint for inhibitors of the enzymes that keep the bacterium's cell walls intact. As a result, Kiessling's group has effectively identified a target for drug manufactures interested in developing new an...
