Identified main genetic variants involved in response to HIV

...larly in a gene encoding a protein which seemingly participates in viral replication, and is also located in chromosome 6. Genetic variants associated to genes encoding HLA-B and HLA-C molecular systems would explain up to 15% of viral load variation among patients, whereas the third genetic variation would exp...

Common cancer gene sends death order to tiny killer

...it of genetic code, a microRNA called miR-34a that participates in p53's uncanny ability to kill cells likely to become malignant because of damaged genes in their nuclei. MicroRNAs are small chains of ribonucleic acid (RNA) made by the same machinery that produces other types of RNA in the cell, such as the mess...

Research suggests beta agonists may alter the immune system

...of type 2 T cells, a type of white blood cell that participates in immune system defense mechanisms. In certain diseases such as asthma and lupus, an over-reactive type 2 T cell response occurs and is believed to contribute to the disease. "Inhaled beta-agonists are very effective in opening up airways and allo...

Technique offers new view of dynamic biological landscape

...ibition." Knowing the interactions a target gene participates in could also enable clinicians to predict the variability of effects of a drug among different people. Understanding such interactions could also give pharmaceutical researchers clues to the magnitude of possible side effects of drugs under developm...

Researchers discover new form of cancer gene regulation

... fate. Once the messenger RNA leaves the cell, it participates in a process called translation, during which the cellular machinery makes a protein by linking amino acids together according to the plan described in the messenger RNA and thereby based on the information from the DNA sequence of the gene. Ianna...

New molecule may aid in production of biofuels and fungi-resistant plants

...gradation. The discovery of this new protein that participates in chitin degradation has many potential applications. For example, transgenic plants that expresses both chitinases and CBP21 would be able to combat fungi by degrading chitin in their cell walls. And, a better understanding of natural chitin turnov...

'License to kill' enables powerful immune attack cells in mice

...looking for a way to see if the human version also participates in some kind of licensing process." The group's research was made possible by a unique mouse line created by Ted H. Hansen, Ph.D., professor of pathology and immunology and of genetics. Mice normally have many different versions of the MHC molecule,...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

... the National Institutes of Health. The ONPRC also participates in the voluntary accreditation program overseen by the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC). ...

New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids

...g to autoreactive T cell activation and, possibly, participates in the pathogenesis of some autoimmune diseases, such as MS and GBS, in which the anti-GSL T cell response may be important," writes Dr. De Libero. The authors suggest that although the autoreactive T cells may play a useful role in promoting the imm...

Discovery of New Dopamine Action May Yield Alternative Psychiatric Drugs

...estin 2 not only controls desensitization but also participates in slow synaptic transmission here by acting as a scaffold for signaling molecules in response to dopamine receptor activation," Caron said. "The observations also provide an alternative pathway by which dopamine receptor activation leads to the exp...

UCSD researchers maintain stem cells without contaminated animal feeder layers

...to three molecules, with activin A, a protein that participates in cellular growth and differentiation, as well as hormone secretion, finally shown in additional testing to maintain the undifferentiated state. The study's first author, Gillian M. Beattie, M.S., UCSD Department of Pediatrics and the Whittier Inst...
