New Technique for Tracking Gene Regulators

...becausethe scientists know that each of these tags lies within, at most, 500to 1,500 bases of a CREB-binding site, they are able to search theregion around the specific locations for CREB binding sequences orgenes that might be regulated by CREB.Using this technique, the scientists have identified some 6,...

Nano-Probes Allow an Inside Look at Cell Nuclei

...ence Livermore National Laboratory. Their success lies in specially prepared crystalline semiconductors composed of a few hundred or thousand atoms that emit different colors of light when illuminated by a laser. Because these fluorescent probes are stable and nontoxic, they have the ability to remain in...

Breakthrough method in nanoparticle synthesis paves the way for new pharmaceutical and biomedical applications

...tant application of these nanoporous nanoparticles lies in the production of pure chiral drugs, which make up over one-third of all pharmaceutical drugs currently sold worldwide. Chiral drugs are comprised of “left-handed?and “right-handed?molecules, both of which are mirror images of each other. Only one...

Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leukemia Prognosis

... in order to save lives." The importance of Mcl-1 lies in the differing roles it plays in health and disease. "On one hand, this protein keeps HSCs and progenitor cells alive and multiplying so the body can maintain its needed supply of blood cells," he said. "However, Mcl-1 also prevents the abnormal w...

...hing?pressure. Scientists say precious information lies in discovering how organisms have adapted and evolved to such conditions. Bartlett and his colleagues probed the genetic makeup of Photobacterium profundum, a bacterium that copes with pressures of 4,000 pounds per square inch. The researchers grow ...

Tendency to hair loss inherited from the mother

...s is inherited. The gene for the androgen receptor lies on the x chromosome. Men always inherit the x chromosome from their mother. In many cases men therefore take after their grandfather on their mother's side rather than their father. However, this defect is not simply caused by one gene: "We have indi...

Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

...e found that the cause of chronic sinus infections lies in the nasal mucus -- the snot -- not in the nasal and sinus tissue targeted by standard treatment. The findings will be published in the August issue of Journal of Allergy and Clinical Immunology and are available online . "This strikingly teaches...

New study: Sexually transmitted disease treatment can be effectively administered by sex partners

...ss of patient-delivered partner treatment probably lies in the fact that, with the more traditional methods, patients just had to admit to their partners that there was a problem. With the new method, the patients can offer their partners a solution. "The patients really like the empowerment of being able...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

...rapies for debilitating neurodegenerative diseases lies in our understanding of how new neurons are created and integrated into mature brain tissue," Zhou said. "This protein is an attractive drug target for either boosting neuron-forming processes or stem cell-based therapies for diseases like Alzheimer'...

Amirikian has improved on past methods by developing a theoretical framework requiring only two-dimensional drawings of arbors. Such drawings are already available in the neuroscience literature for many types of n...

Bioinformatics reveals new gene regulation system

...ription recognize and bind to this sequence, which lies just outside of the gene. Repressor signals commonly work by allowing other proteins to bind on top of the promoter sequence and physically block promoters. Therefore, the duo predicted that the NrdR-box functioned as a repressor sequence. Next, the...
