Study examines how DNA damage is repaired by antioxidant enzymes

A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products ...

Chip simulates metabolism of medicine in human body

(PhysOrg.com) -- A tiny electrochemical cell, developed by researchers of the MESA+ Institute for Nanotechnology, The Netherlands, is able to mimick the behaviour of medicine inside a human body. This chip is presented in ...

A new, sustainable source for a promising cancer killer

Plants produce all types of curious chemicals. Some deter predators. Some smell wonderful. Some even have medicinal value. One of these hidden gems is (–)-jerantinine A (JA), a molecule with remarkable anticancer properties, ...

Cells control energy metabolism via hedgehog signalling pathway

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna ...

A protein provides stress relief for cells

German researchers have shown a new mechanism via which cells defend themselves against stress. Dr. Kathrin Thedieck and Birgit Holzwarth from the Institute of Biology III and the Cluster of Excellence BIOSS Centre for Biological ...

Neutrons seek to stop cancer from hijacking a metabolic highway

After a highly lauded research campaign that successfully redesigned a hepatitis C drug into one of the leading drug treatments for COVID-19, scientists at the Department of Energy's Oak Ridge National Laboratory are now ...
