Nanofluidics sorts DNA for cancer research

(Phys.org) -- Cornell nanotechnology researchers have devised a new tool to study epigenetic changes in DNA that can cause cancer and other diseases: a nanoscale fluidic device that sorts and collects DNA, one molecule at ...

New details about gene regulation explained

(Phys.org) -- When genetic information is read from the genetic blueprint DNA, RNA polymerase II translates it into RNA molecules. The C-terminal domain, abbreviated as CTD, is an important area of the polymerase molecule. ...

Study reveals how ribosomes override their blockades

Ribosomes are "protein factories" in the cells of all living things. They produce proteins based on existing genetic codes stored on special nucleic acid molecules. These molecules, also called messenger RNA (mRNA) due to ...

Researchers use light to switch on gene expression

Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater ...

Research team gives drug dropouts a second chance

(Phys.org) -- A cross-disciplinary team of researchers at the University of Maryland has designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3000 times. Their ...

Small molecules for neural stem cells

European scientists used chemical genetics to discover molecules that could serve as future regenerative medicines to treat neurological and neurodegenerative diseases.

Powerful systems biology

An international team of researchers headed by ETH-Zurich scientists has demonstrated for the first time how to extract testable hypotheses from a vast amount of different measurement data for cells that are about to change. ...
