The human genome is contained within the nucleus of cells. The genome is well protected, but many things can cause DNA damage, including aging, some drugs, and environmental factors like UV rays or ...

Damage to the genetic material of mitochondria – the mitochondrial DNA or mtDNA for short – can lead to diseases such as Parkinson's, Alzheimer's, amyotrophic lateral sclerosis (ALS), cardiovascular ...

Ribonucleic acids (RNAs) are single-stranded molecules that play an essential role in the cells of all living organisms. As "transcripts" of our genes, mRNAs, for example, are involved in the ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

Sermorelin, a synthetic analog of growth hormone–releasing hormone (GHRH 1–29), has long attracted scientific interest due to ...

Partial recovery after ischemic stroke is possible, but the mechanisms involved in this process remain unclear. Researchers identified a whole new pathway promoting brain repair. They discovered ...

Much like humans generate mountains of garbage, our cells are constantly discarding proteins that are damaged or no longer needed. The cellular waste disposal system called the proteasome is best ...

Each injury means a little more as individuals age -- more impact and more healing time. A group of scientists and dermatologists are now looking at the role sweat glands play in how aging skin ...
