MIT device draws cells close -- but not too close -- together

...pment, during which the local cellular environment dictates development of major organs over time, and cancer, in which supporting cells are thought to play a role in tumor formation. ...

Neural stem cell gene plays crucial role in eye development

...es that the degree to which SOX2 gene is disrupted dictates the severity of this condition. "We found that even a reduction in normal SOX2 levels causes problems in these mice and this mimics the problems seen in humans," said Pevny. The scientist pointed out that the problem in eye development in these mi...

Tool developed to silence genes in specific tissues using RNAi

...Wilkinson says. "It is a transcription factor that dictates both the formation of the testes in the embryo, and the function of the testes after birth." Researchers worldwide have been trying to harness the power of RNAi since it was discovered in 1998. RNAi rocked the world of science because of the vast im...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units

...udent Ran Miao will discuss how component identity dictates device properties. He will present the paper, "Synthesis and properties of mixed-metal Ru-Pt complexes: Coupling light absorbers to reactive metal centers" (INOR 105) at 3:30 p.m., Sunday, March 26, at the Georgia World Congress Center room B408.

HIV inserts into human genome using a DNA-associated protein

...y demonstrates the first piece of a mechanism that dictates where HIV integration takes place. Previous studies at other institutions showed that LEDGF binds tightly to HIV integrase, the enzyme that's important for the integration reaction. Now, Penn researchers showed in this study that the way LEDGF binds ...

Beyond genes: Lipid helps cell wall protein fold into proper shape

...ane protein's genetically determined sequence that dictates how it folds so that it can function properly. Its lipid environment also plays a role," Dowhan said. "People used to assume that specific lipids made no difference." In the JBC paper, Dowhan and colleagues looked at how a protein called GabP, which...

Fluorescing lab worms signal longer life spans

...en, heterogeneous, but now quantifiable state that dictates the ability of an organism to deal with the rigors of living," the team wrote in Nature Genetics. An automated "worm sorter" equipped with a laser scanner to swiftly detect fluorescence levels in the nematodes and a pneumatic device that separates t...

High fidelity keeps human DNA assembly line humming

...ic material that holds the blueprint for life. DNA dictates orders to RNA to make proteins, which give a cell its identity. Mistakes in RNA synthesis can lead to cancer or can support the life cycle of an invading virus. Researchers consider control of RNA synthesis to be a huge issue in human health. It is a...
