The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

Scripps Research scientists have discovered how some tumors endure DNA damage, revealing a potential new way to target them. The DNA inside our cells is constantly exposed to damage, and one of the ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

The tight wrapping of genomic DNA around nucleosomes in the cell nucleus makes it unavailable for gene expression. A team of Ludwig-Maximilians-Universitaet (LMU) in Munich now describes a mechanism ...

Cedars-Sinai researchers have created TY1, an experimental RNA-based drug that helps the body repair damaged DNA and restore injured tissue. The idea came from studying tiny molecular “messages” ...

Two studies provide a radically new picture of how bacterial cells continually repair damaged sections (lesions) in their DNA. Two studies provide a radically new picture of how bacterial cells ...

A Florida State University College of Medicine researcher has made a discovery that alters our understanding of how the body’s DNA repair process works and may lead to new chemotherapy treatments for ...

Researchers are reporting new technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known.

BUFFALO, N.Y. — Radiation therapy, a common treatment for some oral cancers, can leave a patient’s salivary glands so damaged that even talking is difficult. Meanwhile, diseases such as Sjogren’s, ...

Biochemistry is the study of the chemicals and chemistry of living organisms. Biochemists study biomolecules (such as proteins, RNA, DNA, sugars, and lipids), their applications and interactions in ...
