Adapting fish defenses to block human infections: Antimicrobial peptide of fish gills inspire clean surfaces

Adapting fish defenses to block human infections: Antimicrobial peptide of fish gills inspire clean surfaces

ScienceDaily (Nov. 29, 2012) — An undergraduate research team analyzes peptides from fish gills to engineer antimicrobial surfaces for food preparation and medical devices. Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses against waterborne pathogens, including antimicrobial peptides located in their gills Continue reading

Chromatin remodeling: Activating ACL1 with a little help from ‘friends’

ScienceDaily (Nov. 29, 2012) — Chromatin remodeling — the packaging and unpackaging of genomic DNA and its associated proteins — regulates a host of fundamental cellular processes including gene transcription, DNA repair, programmed cell death as well as cell fate. In their latest study, scientists at the Stowers Institute for Medical Research are continuing to unravel the finicky details of how these architectural alterations are controlled Continue reading

Hepatitis C treatment’s side effects can now be studied in the lab

ScienceDaily (Nov. 16, 2012) — The adverse side effects of certain hepatitis C medications can now be replicated and observed in Petri dishes and test tubes, thanks to a research team led by Craig Cameron, the Paul Berg Professor of Biochemistry and Molecular Biology at Penn State University. “The new method not only will help us to understand the recent failures of hepatitis C antiviral drugs in some patients in clinical trials,” said Cameron.
