Cellular ‘cruise control’ system safeguards RNA levels in Rett syndrome nerve cells

Cis-acting elements in the 3ʹUTR are highly associated with half-life changes. a Random forest classifier for prediction of mRNA sequence features relevant for half-life fold-change in human NEURTT and in…

Stress Rapidly Increases Biological Age, but Recovery Turns Back the Clock

Summary: Stress can cause rapid and transient increases in biological age, which can be reversed upon recovery, according to a new study. Using DNA methylation clocks, researchers found that stress…

Omomyc induces growth arrest in melanoma human cell lines in vitro. (A) Growth inhibition by transgenic Omomyc at 10 d by Crystal Violet staining. (B) Early effect of Omomyc on…

Turning Gray: Stuck Stem Cells Turn Hair Gray

Summary: A new study sheds light on why we tend to go gray as we age. Researchers found melanocyte stem cells get stuck as we grow older, losing the ability…

A New Peptide May Hold Potential as an Alzheimer’s Treatment

Summary: Researchers say a peptide that blocks the hyperactive version of the CDK5 enzyme reduces neurodegeneration and DNA damage in mouse models of Alzheimer’s disease. Animals treated with the peptide…
