DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

The loss of epigenetic information accelerates the aging process

A new study in the journal Cell aimed to determine whether epigenetic changes are a cause of mammalian aging.

Researchers unveil new methods for DNA mosaic recognition

As humans, we each have trillions of cells. And each cell has a nucleus with individual genetic information –DNA – that can mutate to create an abnormality.

Scientists use paleogenomics to trace 10,000 years of human immune system evolution

Scientists from the Institut Pasteur, Université Paris Cité, the CNRS and the Collège de France have used paleogenomics to trace 10,000 years of human immune system evolution.

Machine learning tools help unravel why human accelerated regions evolved so quickly

Humans and chimpanzees differ in only one percent of their DNA. Human accelerated regions (HARs) are parts of the genome with an unexpected amount of these differences.

Study shows the importance of social support in buffering genetic depression risk

Reaching out to support a person when they're under stress is always a good idea. But a new study suggests that support could be especially important for someone whose genetic makeup makes them more likely to develop depression.

Comprehensive atlas of protein kinases could help scientists decipher many cellular signaling pathways

One of the most important classes of human enzymes are protein kinases -; signaling molecules that regulate nearly all cellular activities, including growth, cell division, and metabolism.

Bacteria play specific roles in cancer

In a recent article published in the journal Immunity, the authors discussed the findings from a 2022 study by Galeano Niño et al., which reported that microbiota associated with tumors form micro-niches and play a role in epithelial and immune mediations of cancer.

Study reveals why older male fruit flies are more likely to pass mutations onto their offspring

The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers.

Unique mass spectrometry-based approach to study specific changes in DNA after replication

A new method to study specific changes in DNA after replication has been published as a technical report in Nature Cell Biology.

Using lipid nanoparticles and messenger RNA to treat blindness associated with rare genetic condition

Oregon State University College of Pharmacy scientists have demonstrated in animal models the possibility of using lipid nanoparticles and messenger RNA, the technology underpinning COVID-19 vaccines, to treat blindness associated with a rare genetic condition.

Green tea may protect against telomere shortening due to biological aging

A new study in Scientific Reports aimed to analyze the association between cross-section and longitudinal LTL changes with the consumption of soft drinks, coffee, and tea among middle-aged and older Korean men and women for six years. It also assessed any changes in the association results according to a difference in sex and age groups.

New genetic test could guide the treatment of ovarian cancer

Researchers have developed an optimized genetic test for ovarian cancer, which helps accurately target an effective but expensive medication.

Study identifies LAP1 as a master regulator of nuclear envelope remodeling during melanoma progression

Researchers discovered that the elevated expression of LAP1, an inner nuclear membrane protein, helps metastatic melanoma cells surmount the physical challenges presented by tissue structure and the microenvironment during metastasis.
