Researchers reveal DNA repair mechanism

Posted by in categories: biotech/medical, genetics, health

A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA.

Published online May 16 in the journal Cell, the report describes the behind a DNA repair pathway that counters the mistaken inclusion of a certain type of molecular building block, ribonucleotides, into genetic codes. Such mistakes are frequent in code-copying process in bacteria and other organisms. Given that ribonucleotide misincorporation can result in detrimental DNA code changes (mutations) and DNA breaks, all organisms have evolved to have a DNA repair pathway called ribonucleotide excision repair (RER) that quickly fixes such errors.

Last year a team led by Evgeny Nudler, Ph.D., the Julie Wilson Anderson Professor in the Department of Biochemistry and Molecular Pharmacology at NYU Langone Health, published two analyses of DNA repair in living E. coli cells. They found that most of the repair of certain types of DNA damage (bulky lesions), such as those caused by UV irradiation, can occur because damaged code sections have first been identified by a called RNA . RNA polymerase motors down the DNA chain, reading the code of DNA “letters” as it transcribes instructions into RNA molecules, which then direct protein building.

Insight into brain’s waste clearing system may shed light on brain diseases

Posted by in categories: biotech/medical, engineering, neuroscience

Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke.

A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has found a non-invasive and non-pharmaceutical method to influence glymphatic transport using , opening the opportunity to use the method to further study diseases and . Results of the work are published in the Proceedings of the National Academy of Sciences on May 15.

Hong Chen, associate professor of biomedical engineering in McKelvey Engineering and of in the School of Medicine, and her team, including Dezhuang (Summer) Ye, a postdoctoral research associate, and Si (Stacie) Chen, a former postdoctoral research associate, found the first direct evidence that focused , combined with circulating microbubbles—a technique they call FUSMB—could mechanically enhance glymphatic transport in the mouse brain.
