Scientists unravel how DNA damage may trigger lupus erythematosus

Summer, sun and the sea - a dream vacation for most - can turn sour for those affected by lupus erythematosus. For them, absorption of the UV-light component in sunlight may cause florid inflammation and redness of the skin. Scientists of the University Hospital Bonn, Germany have now discovered which signaling pathway of the innate immune system promotes autoimmune symptoms following sun-induced DNA damage.

Scientists present novel method to visualize how nuclear protein mobility changes following DNA damage

Understanding the cellular response to DNA strand breaks is crucial to decipher the mechanisms maintaining the integrity of our genome. In eukaryotic cells, the molecular events triggered by DNA damage are strongly influenced by the local chromatin environment surrounding the lesion. The ensuing DNA repair process, in turn, impacts on chromatin structure. In order to understand how these two fundamental processes are mutually connected, both chromatin rearrangements induced by DNA damage as well as DNA repair activity have to be visualized in living cells.

Quickly clearing out damaged proteins may help prevent neurodegenerative disorders: Study

Recycling is not only good for the environment, it's good for the brain. A study using rat cells indicates that quickly clearing out defective proteins in the brain may prevent loss of brain cells.

Newly developed approach could benefit basic medical research and help detect H2S in environment

University of Oregon chemists have developed a selective probe that detects hydrogen sulfide (H2S) levels as low as 190 nanomolar (10 parts per billion) in biological samples.

Researchers uncover DNA damage checkpoint used by cells to monitor oxidatively damaged DNA

In current health lore, antioxidants are all the rage, as "everybody knows" that reducing the amount of "reactive oxygen species" -- cell-damaging molecules that are byproducts of cellular metabolism -- is critical to staying healthy. What everyone doesn't know is that our bodies already have a complex set of processes built into our cells that handle these harmful byproducts of living and repair the damage they cause.

Hebrew University student develops drug formulations to treat illnesses through skin applications

New, more efficient drug formulations designed to treat illnesses through skin applications -- thus avoiding serious side effects associated with oral drug-taking -- have been developed by a student at the Hebrew University of Jerusalem.

Study suggests modulation of "enhancer-directed RNAs" can alter gene expression in living cells

In a pair of distinct but complementary papers, researchers at the University of California, San Diego School of Medicine and colleagues illuminate the functional importance of a relatively new class of RNA molecules.

New TGT method helps detect and measure mechanics of single-molecule interaction

Cells in the human body do not function in isolation. Living cells rely on communication with their environment-neighboring cells and the surrounding matrix-to activate a wide range of cellular functions, including reproduction of new cells, differentiation of stem cells into distinct cell types, cell adhesion, and migration of white blood cells to fight bodily infections.
