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

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 ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune ...

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 ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published today as a Reviewed Preprint in eLife, is described by the editors as a ...

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.

Biochemistry plays an important role in the treatment of disease. Biochemistry incorporates elements of pharmacology, pathology, cell biology, and physiology to explain both the basis and proposed ...

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, ...
