Researchers use RNAi libraries to identify regulators of apoptosis and chemoresistance

...ts have not been able to establish a direct causal link between these alterations and human cancer growth. Determining whether these mutations have the potential themselves to induce cancer or simply play a supporting role also has been difficult. To determine the impact of genetic alterations associated...

UIC researchers show protein routes messages in nerve cells

...ate receptors, but there's never previously been a link found to the cytoskeleton," said Featherstone. "This work finally ties the receptors to the cell framework to provide a complete picture." Confirmation of these mechanisms in a mammal such as a mouse or a rat can help researchers understand how nerv...

Insight into our sight: A new view on the evolution of the eye lens

... the evolution of the lens, there was a regulatory link between two tiers of genes: those that would later become responsible for controlling lens development, and those that would help give the lens its special physical properties. This combination of genes appears to have then been co-opted in an early ...

No small feat: First ever gene therapy success for muscular dystrophy achieved

Monkeys understand numbers across senses

...o sounds or visual images, we're using language to link these different sets from different modalities. And the question has been whether an animal without that kind of language based representation can still notice or represent these commonalities." According to Jordan, their research team is planning f...

New understanding of jet lag

...otransmitter GABA (gamma-aminobutyric acid) as the link between the two clock parts that eventually pulls them back into synchronization, according to co-investigator Gene D. Block, professor of biology at the University of Virginia. Block likens GABA to a weak rubber band linking pendulums swinging at d...

Errors in the measurement of global warming corrected

... in darkness. "Even though models predict a close link between atmospheric and surface temperatures, there has been a large difference in the actual measurements," said Steven C. Sherwood, associate professor of geology and geophysics at Yale, and lead author. "This has muddied the interpretation of repo...

Study: Plants use dual defense system to fight pathogens

Researchers have uncovered the link between two biochemical pathways that plants use to defend themselves against pathogens ?pathways that scientists have long believed worked independently of each other. Knowing how these pathways of immunity work may one day help researchers breed p...

Making plant cells work like miniature factories

...d of genomics gives scientists genetic roadmaps to link certain genes to diseases. The subsequent study of proteins produced by certain genes spawned the field of proteomics. Now, a group of researchers at the U.S. Department of Energy's Ames Laboratory at Iowa State University will use $1.02 million in ...

Freeze-dried mats of microbes awaken in Antarctic streambed

...nels under study feature intermittent streams that link glaciers to frozen lakes on the valley floor, she said. The streambeds contain photosynthetic microbes known as cyanobacteria, which collectively occur as thin, rubbery mat-like structures that can spread several meters across the streambed surface. ...

Genetic link confirmed between Polynesians and indigenous Taiwanese

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...plications, Frank sees the parasite as a primitive link to modern eukaryotes and its ribosome as a source of potential insights into the evolution of more complex organisms. "Ribosomes perform the translation of genetic information into protein in all organisms," Frank said. "The principle is always the ...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

...search by Back and other scientists had revealed a link between the white matter brain damage associated with premature birth and damage to immature cells in the brain and spinal cord, called oligodendrocyte progenitors. These precursor cells give rise to all of the mature oligodendrocytes that make myeli...

Schizophrenia is a common form of severe mental illness characterized by thought disorder, halluc...

Study hints at role of stem cell genes in testicular, breast cancers

...roviding some of the first molecular evidence of a link between embryonic stem cells and cancer. The finding, reported in the November issue of Cancer, suggests that the genes may play a role in the development of tumors or serve as valuable markers of tumor progression, the researchers say. As such, the...
