Hidden influenza virus protein found

...hen the scientists examined the gene encoding this peptide more closely, they noticed it was suspiciously long for mere junk.Wondering if this molecule might be a bonafide protein, Dr. Yewdell’s team decided to see how much of it was created in cells infected with the flu virus. If it were junk, there should...

Slowing Down The Progression Of Alzheimer’s Disease

...appears to prevent the aggregation of beta-amyloid peptide Abeta (1-40) in vitro, dissolving the dense fibres that form in the brain over time. Researchers believe that this data provides the molecular basis for explaining the beneficial effect of Colostrinin in patients with mild and moderate Alzheimer's di...

Controlled Gene Expressions Can Cure Many Diseases

...irst, they developed a synthetic molecule called a peptide nucleic acid, or PNA, which physically binds to DNA and blocks enzymes from copying, or transcribing, the DNA into messenger RNA. More importantly, the researchers also employed RNA itself as a silencing agent. The researchers designed their RNA to...
