Gene Expression in Blood may Hold Clues About Chronic Fatigue Syndrome

...ant because it is the process by which a genes DNA sequence is converted into the proteins that ultimately determine the manifestations of disease. Researchers studied the expression of 30,000 genes in the blood, testing each person between four and five times over a 12-month period. The study found that ...

Amorous African Fish Exchange Electric Pulses While Mating

...vior of the fish. Wong, who described the whole sequence as "electrical duetting", said both males and females seemed to make specific "sounds" before, during, and after mating. The signals aren't actually songs, because the fish sense them electrically rather than acoustically, Wong added. Early bio...

Advancement in Gene Associated With Colon Cancer

...ving rapidly since the publication of the complete sequence of the human genome in 2003. Says Gruber, The mystery of the relationship between our genetic code and disease is now starting to become clear, and many scientists are turning to the same chapter to find important clues to colorectal cancer. He and h...

New Target for Muscular Dystrophy Drug Therapy Discovered

...roduction," explains Dr. Khurana. Since the gene sequence of utrophin is over 80 per cent identical to that of dystrophin, it may substitute for dystrophin in muscle cells, says researchers. Dr. Khurana, however, wants to ensure first whether repressing ERF reduces muscle deterioration in mice or not. ...

Genes Influence the Ability to Listen Two Things at a Time

...e direction a sound is coming from, the timing and sequence of a sound, and whether a sound is a voice we need to listen to or background noise we should ignore. Most people dont even realize they possess these skills, much less how adept they are at them. Auditory processing skills play a role in a childs ...

Weizmann Researchers Developed Control Switch for Protein Activity

...a short segment of amino acids into the amino acid sequence making up the protein. This segment is capable of binding strongly and selectively to a particular chemical drug, which affects the activity level of the engineered protein by increasing or reducing it. When the drug is no longer applied, or when it ...
