Clones on task serve greater good, evolutionary study shows

...children. In Arabadopsiss case, the solid Family A produces more children or flowers, than the erratic Family B.As it turns out, and perhaps not surprisingly, those genotypes that tended in general to vary more, tended to not produce as many flowers (and thus were less likely to reproduce successfully), Dwor...

Diverse genetic abnormalities lead to NF-κB activation in multiple myeloma

... is a cancer of the plasma cell, a blood cell that produces antibodies to help the body fight off infections. Previous research implicates abnormal activation of the NF-κB signaling pathway as a key event in MM pathology. NF-κB target genes are known to be involved in cell proliferation and cell sur...

Interaction of just 2 genes governs coloration patterns in mice

...is the combination of mutations in both genes that produces a mouse very light in color. "Thus, two different types of mutations in two different genes each contribute to the light coloration of beach mice," Hoekstra says. "This work represents a first step into understanding how unique patterns of fur colo...

Genetic variation helps to understand predisposition to schizophrenia

... variations in a DNA sequence close to a gene that produces a protein called Neuregulin 1 were associated with schizophrenia, but how the Neuregulin 1 gene was affected remained unknown. In 2006, Law and colleagues found that one of these DNA variations is associated with increased expression of a novel ty...

1 of deep ocean's most turbulent areas has big impact on climate

...e studys co-principal investigator, because mixing produces the overall balance of water temperatures that helps control the strength of the Gulf Stream -- the strong, warm ocean current that starts in the Gulf of Mexico, flows along the U.S. east coast to Canada and on to Europe, and plays a crucial climate ...

Evolution is driven by gene regulation

... difference must be in the way regulation of genes produces their protein products. Comparing gene regulation across similar organisms has been difficult because the nucleotide sequence of DNA regulatory regions, or promoters, are more variable than the sequences of their corresponding protein-coding regio...

UCLA scientists produce functioning neurons from human embryonic stem cells

...u should use a human embryonic stem cell line that produces the neurons from that region of the brain to get the most accurate results from your study. Huntingtons disease, for example, is a forebrain disease, so the neurons should be differentiated from a cell line that is biased to produce neurons from the ...

UCF research links proteins, stem cells and potential Alzheimer's treatment

...unts of the amyloid-precursor protein (APP), which produces a component of the plaques, a hallmark of Alzheimers, prevent stem cells from becoming neurons. The research team treated Alzheimers-model mice producing human APP with phenserine, which is known to reduce the amount of APP in the brain. The APP l...

Genetic analysis finds greater threat in frog-killing fungus

...n Queensland, Australia. "If, in fact, this fungus produces resistant spores, people could be unwittingly transferring this pathogen around the world from dirt on our shoes or car tires. But spores could also hitchhike on the feathers of birds for quick transport across mountain ranges." Moreover, if resist...

Phase II study of therapeutic vaccine shows efficacy in patients with metastatic colorectal cancer

... The idea is that the modified virus enters cells, produces the tumor protein and stimulates the immune system, said lead study author Richard Harrop, Ph.D., vice president of clinical immunology at Oxford BioMedica. To give a vaccine alongside chemotherapy might seem counterintuitive, since chemotherapy can ...

Einstein researchers' prototype vaccine could provide improved protection against tuberculosis

...live, attenuated M. tuberculosis strain that still produces a strong immunological response that protects people. TB bacteria invade human cells and then--successfully evading a persons immune response--lurk inside cells and multiply. A key evasion strategy involves preventing their host cells from undergoi...

...is gene is activated in any way, the reporter gene produces an easily detectable protein, such as green fluorescent protein (GFP). The scientists are then able to 'read' this 'report' and learn about the specific events that are occurring and in what regions. The light given off by these proteins is scatter...

It sets a solid foundation for self-powering implantable and wireless nanodevices...

'Preconditioning' helps protect brain's blood vessels from stroke

...certain enzymes that produce NO. This process also produces destructive, oxidative byproducts called free radicals. According to the new study, NO combines with these free radicals to produce low levels of another molecule, called peroxynitrite. "At higher levels, peroxynitrite is a very dangerous chemic...

New clue into how diet and exercise enhance longevity

...f the Irs2 gene in mice reduces brain growth and produces diabetes due to pancreatic beta cell failure. However, in the new study, when the researchers knocked out only one copy of the gene, they found the mice lived 18 percent longer than normal mice. Because reducing insulin-like signaling in the neurons...

New proteomics research promises to revolutionize biomedical discovery

...ower to build a proteomics discovery pipeline that produces only relevant, useful information (as Google is also efficient to map useful links for a Web search, leaving out most irrelevant information). Given the success seen thus far, Dr. Coulombe may well be on the right road to achieve his long-term object...

Researchers discover gene responsible for Restless Legs Syndrome

...land. Restless legs syndrome is a condition that produces an intense, often irresistible urge to move the legs and is a major cause of insomnia and sleep disruption. RLS affects approximately 10 percent of the U.S. population and about one percent of school-aged children. The discovery provides strong new e...

This chemical substance is essential in making the memory work correctly. The nucleus basalis magnocellularis equivalent in humans is the nu...
