A host’s genes likely influence the spread of antibiotic resistance

February 16, 2020 dna 0
New findings in mSphere suggest that the genetic makeup of the host organism can influence the transfer of plasmids. By identifying the host factors that facilitate or stop plasmid transfer, the researchers hope to identify new ways to stop the spread of antibiotic resistance, which kills tens of thousands of people every year in the United States alone.

Genetic screen offers new drug targets for Huntington’s disease

February 15, 2020 dna 0
Using a genetic screen that was previously impossible in the mammalian brain, neuroscientists have identified hundreds of genes that are necessary for neuron survival. They also used the approach to identify genes that contribute to the toxic effects of mutant protein that causes Huntington’s disease.
