will help researchers understand the onset and progression of these diseases as well as help them find a cure for cancer. ...
Features of replication suggest viruses have common themes, vulnerabilities
...es use to reproduce have common attributes. Such a discovery
is important because it reveals a common viral theme that may be vulnerable to disruption and could lead to the development of drugs to treat many different kinds of viral infections, much like antibiotics are used to attack different kinds of bacter...
New, more direct pathways from outside the cell-to-cell nuclei discovered

means that "one less step is needed for extracellular material to get into the nucleus, and so it is...
Circadian clock controls plant growth hormone
...in the plant, UC Davis researchers have found. The discovery
explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms. Auxin tells shoots to grow away from the ground and toward light and wa...
deCODE discovers cause of major subtype of glaucoma

of two common single letter variations (SNPs) in t...n upcoming print edition of the journal. This discovery
is remarkable and important because the genetics has led us directly to what appears to be the sole ...
OHSU turns mouse into factory for human liver cells
...commercial sector, said market demand for Grompe's discovery
is high. OHSU has filed a patent application on the technology and, in cooperation with Grompe, has spun it off into a Portland-based start-up company named Yecuris through the university's Springboard Program. "Yecuris is a viable start-up company...

...ly how the cancer will respond to treatment.' This discovery
may, in the future, aid in the development of drugs to prevent or reduce the production of the unwanted protein, and thus prevent metastasis in breast or other cancers. ...
Almac Diagnostics announces pioneering genetic research on ductal carcinoma in situ
... novel technology is helping researchers to reduce discovery
timelines, accelerate the validation process and ultimately deliver clinical applications in this disease setting. said Paul Harkin, BSc, PhD, Professor of Molecular Oncology at the Centre for Cancer Research and Cell Biology, Queens University, Belf...
Inflammation may cause preterm labor and fetal deaths
...ponse to bacteria and produced healthy pups. This discovery
led Han and her colleagues to attempt to block the inflammatory process by using synthetic TLR4 antagonist that prevented the receptor from sensing the bacteria. Fusobacterium nucleatum, a common oral pathogen also found in the amniotic fluid of p...
In limiting life span, study finds booming bacteria innocent
...teria had no effect on life span, they found. That discovery
led the researchers to conclude that, at least under optimal laboratory conditions, Drosophila can tolerate a significant number of bacteria and mount a strong innate immune response against them without cutting their 65-day lives any shorter. Ther...
Penn researchers discover how key protein stops inflammation
...toid arthritis. The novelty of our study is the discovery
that Bcl-3 acting on gene expression has a profound effect on inflammation, says Ruaidhri Carmody, PhD, Senior Research Investigator in the Department of Pathology and Laboratory Medicine and first author of the Science paper. By mimicking Bcl-3 acti...
UCLA scientists produce functioning neurons from human embryonic stem cells

in Suns study showed that two embryonic stem cells lines derived in similar manners, and therefore expected to behave similarly when differentiating, did not. Using the same techniques to prod the two embryonic stem cells lines to differentiate, Sun ...
Not all embryonic stem cell lines are created equal

that a variation in a serotonin-related gene could affect response to citalopram was not entirely surprising, since the serotonin system is known to be involved in depression. Citalopram targets this system. But GRIK4 makes a protein that acts as a r...
