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).

Novel computational method quantifies the coordination level between different genes

Although all humans share similar changes during aging such as gray hair, wrinkles, and a general decline in function, aging is considered to be the result of a cellular wear-and-tear process due to accumulated random damage, such as genetic mutations or DNA structural damage.

Computational method reveals a new hallmark of aging

While all human beings share changes during aging, like wrinkles, gray hair, and a general drop in function, aging is assumed to be the outcome of a cellular process.

Pancreatic cancer cells avert starvation by signaling to nerves, shows study

Pancreatic cancer cells avert starvation by signaling to nerves, which grow into dense tumors and secrete nutrients. This is the finding of a study with experiments in cancer cells, mice, and human tissue samples published online on November 2 in Cell.

Study reveals proteins that enable SINEUPs to increase protein production

Scientists from an international group led by the RIKEN Center for Integrative Medical Sciences and Yokohama City University have discovered that a pair of proteins play a key role in allowing an important type of functional non-coding RNA, known as SINEUPs, to act to promote their target messenger RNA.

Gut microbes mitigate radiation exposure, repair GI tract

A new study by scientists at UNC Lineberger Comprehensive Cancer Center and colleagues published Oct. 30, 2020, in Science, showed that mice exposed to potentially lethal levels of total body radiation were protected from radiation damage if they had specific types of bacteria in their gut.
