An Ode to the Brain

In honor of the Society for Neuroscience’s 2012 meeting being held this coming week in New Orleans, we present you with an Ode to the Brain.

A virus a day keeps the pimples away

 :: Posted by American Biotechnologist on 09-25-2012

Scientists have isolated and studied the genomes of 11 viruses, known as phage, that can infect and kill the acne-causing bacterium Propionibacterium acnes, potentially paving the way for topical therapies that use viruses or viral products to treat this vexing skin condition. Their results are reported in the September 25 issue of mBio®, the online open-access journal of the American Society for Microbiology.

“There are two fairly obvious potential directions that could exploit this kind of research,” says Graham Hatfull of the University of Pittsburgh, an author of the study. “The first is the possibility of using the phages directly as a therapy for acne. The second is the opportunity to use phage-derived components for their activities.”

New Molecular Tool for Prognosis and Treatment of Brain Tumors

 :: Posted by American Biotechnologist on 01-17-2012

In a paper recently published in BMC Medical Genomics, scientists from Sandra L Rodriguez-Zas’ lab at the University of Illinois have identified a cohort of biomarkers that help predict survivability of patients who are afflicted with the aggressive malignant Glioblastoma multiforme brain tumor. The study also found that survivability varies between different genetic profiles and that factors such as race, gender and therapy may have a significant impact upon the survival and quality of life of individuals afflicted by glioblastoma multiforme.

Why our brains are more unique in our childhood and old age

 :: Posted by American Biotechnologist on 10-27-2011

Despite vast differences in the genetic code across individuals and ethnicities, the human brain shows a “consistent molecular architecture,” say researchers supported by the National Institutes of Health. The finding is from a pair of studies that have created databases revealing when and where genes turn on and off in multiple brain regions through development.

“Our study shows how 650,000 common genetic variations that make each of us a unique person may influence the ebb and flow of 24,000 genes in the most distinctly human part of our brain as we grow and age,” explained Joel Kleinman, M.D., Ph.D., of the National Institute of Mental Health (NIMH) Clinical Brain Disorders Branch.

Kleinman and NIMH grantee Nenad Sestan, M.D., Ph.D. of Yale University, New Haven, Conn., led the sister studies in the Oct. 27, 2011 issue of the journal Nature.
