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 ...

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 ...

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 ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...

In specialized chambers throughout leading medical centers worldwide, patients breathe pure oxygen at pressures significantly higher than normal atmospheric conditions. This treatment, known as ...

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 ...

Like jewels in a vault, our precious genetic material is stored in the nucleus of a cell--sequestered away from potentially damaging cellular components and toxins so that no harm can come to it. Yet ...

Each cell in our body experiences up to tens of thousands of DNA-damaging events per day, primarily from routine cellular maintenance or exposure to toxins in our environment. Despite the high ...
