Genomic Analysis Uncovers New Targets for HIV Vaccine

...M, N.C. – An international team of researchers has identified three gene variants in the DNA of 486 people infec...etroviral treatment. The three polymorphisms were identified after all the blood samples of the selected patients were screened for more than 555,000. Additiona...

Scratch no more: Gene for itch sensation discovered

...on University School of Medicine in St. Louis have identified the first gene for the itch sensation in the centr...has been somewhat neglected. "Many genes have been identified in the pain pathway," says Chen, associate professor of anesthesiology, psychiatry and molecular bio...

Identified main genetic variants involved in response to HIV

...estroys cells infected by HIV. This study has also identified a third genetic variation involved in immune damage of patients, particularly 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 a...

Common cancer gene sends death order to tiny killer

...une 8 issue of Molecular Cell. The research team identified a tiny bit 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 ...

Researchers discover inherited mutation for leukemia

...of cells before they become cancerous. Researchers identified the mutation by testing a family in which the fath...says. The family examined in this research was identified by collaborator Henry Lynch at Creighton University. The researchers are now studying the chemic...

Old memory traces in brain may trigger chronic pain

...at Northwestern’s Feinberg School of Medicine, has identified a drug that controls persistent nerve pain by targeting the part of the brain that experiences the emotional suffering of pain. The drug is D-Cycloserine, which has been used to treat phobic behavior over the past decade. In animal studies, D-Cy...

Discovery in orange cauliflower may lead to more nutritious crops

...ritional advantages. Now, Cornell researchers have identified the genetic mutation behind the unusual hue. The finding may lead to more nutritious staple crops, including maize, potato, rice, sorghum and wheat. The genetic mutation recently isolated by Cornell plant geneticist Li Li and colleagues -- and desc...

New bacterium discovered -- related to cause of trench fever

...chalimae, is also closely related to the bacterium identified about 10 years ago as the cause of cat scratch dis... Before 1990, no Bartonella infections had been identified in the U.S. The new discovery is the sixth species identified that can infect humans, said Jane Koeh...

Study shows big power of small RNAs, not just proteins, in halting cancer

...ughes Medical Investigator (HHMI) Greg Hannon have identified a family of micro RNAs (miRNAs) that enable a critical tumor suppressor network, called the p53 pathway, to fight cancer growth. “At CSHL, we are moving simultaneously on several fronts to understand the p53 pathway because damage to this pathway is...

Brain holds clues to bipolar disorder

...lar disorder. Using neuroimaging, Dr. Phillips has identified patterns of abnormalities in the neural systems that underlie emotional processing and cognitive control unique to the bipolar brain. Such abnormalities are valuable biomarkers for the illness and have the potential to help clinicians diagnose bipola...

Stroke study sheds light on left-right brain divide

...brains have been damaged by a stroke. The research identified the role of the right side of the brain in noticing and correcting errors. The research focused on damage to the frontal lobes, the front part of the brain which is known to be responsible for aspects of language, decision making and learning. The t...

Breakthrough developments in rheumatoid arthritis reported

'Lucky 13' as new gene discovery offers further hope for childhood blindness

... with experts from other centres around the world, identified the gene, which is essential to photoreceptors in the eye, the cells that "see" light. The finding, the thirteenth gene to be linked to Leber’s congenital amaurosis (LCA), comes at a time of hope for the people born with the disorder. Scientists at...

Newly discovered antibody may be body's natural defense against Alzheimer's

...yterian Hospital/Weill Cornell Medical Center have identified naturally occurring antibodies in human blood that may help to defend against this form of dementia as well as other neurodegenerative diseases. The newly found antibodies selectively target aggregates of beta amyloid proteins called "oligomers" th...

Researchers shed light on mechanism of action used by anti-cancer drug

...ter’s cancer cell biology program, VCU researchers identified a mechanism by which sorafenib inhibits protein translation, and which may be involved in reducing expression of pro-survival factors, such as Mcl-1, and other proteins. The findings were published online in the journal Molecular and Cellular Biology...

Massive herds of animals found to still exist in Southern Sudan

...kob migration in Boma National Park. The team also identified a key zone of semi-arid habitat supporting several species, which will be proposed as a new protected area. (OVER) In an effort to protect this newly discovered natural resource, WCS has signed cooperation agreements with both GoSS and its Mini...

Study shows lizard moms dress their children for success

...rying to hide in the grass, for example. Lancaster identified two pathways by which an extra dose of estradiol from the mother can help to resolve this problem. In one pathway, females increased the amount of estradiol to their eggs when their mate had a yellow throat. The hormone induced a barred back patte...

CT scan reveals ancient long-necked gliding reptile

... all of the bones. Because this fossil has been identified and named from CT scan, one benefit is that the bones themselves have not been destroyed or even moved. Exact positioning of the bones removes any doubts about joint connections and position. Also, both the fossil specimens and the image data from th...

Genetic factors are linked to fever following smallpox vaccination

...y’s response to viral infections. The new study identified a total of eight haplotypes in four different genes that were associated with altered susceptibility to fever after vaccination. It is the first study to show that fever after smallpox vaccination is associated with specific gene clusters in the inte...

Herpes virus hijacks DNA repair process

...hington University School of Medicine in St. Louis identified a protein that can trick the mouse cell into turning on the DNA damage response. They also showed that Epstein-Barr virus, a human herpes virus, has a similar protein. Scientists found that blocking murine herpes virus from activating the DNA damage ...
