Selectively manipulating protein modifications
Protein activity is strictly regulated. Incorrect or poor protein regulation can lead to uncontrolled growth and thus cancer or chronic inflammation. Members of the Institute of Veterinary Biochemistry and Molecular Biology ...

Assembling the transcriptome of a noxious weed: New resources for studying how plants invade
In order to build and maintain cells, DNA is copied into ribonucleic acid (RNA) molecules, also called transcripts. Transcripts are often like a recipe for making proteins, and a collection of all the transcripts in a cell ...

Life's tiniest architects pinpointed
If a genome is the blueprint for life, then the chief architects are tiny slices of genetic material that orchestrate how we are assembled and function, Yale School of Medicine researchers report Feb. 21 in the journal Developmental ...

Histone modification controls development: Researchers demonstrate that chemical tags on histones regulate gene activity
Every gene in the nucleus of an animal or plant cell is packaged into a beads-on-a-string like structure called nucleosomes: the DNA of the gene forms the string and a complex of proteins called histones forms the beads around ...

Protein paves the way for correct stem cell differentiation
A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. If the regulation is lost, specialized ...

Mathematician models the spread—and prevention—of crime as a wave
(Phys.org)—Crime can happen anywhere, but it usually doesn't. Researchers have noticed that criminal activity seems to be concentrated in self-perpetuating hotspots. Crime leads to more crime. Then, from these epicenters, ...

Stem cells: Tuning the death sentence
In this week's issue of Science Signaling (22 January, 2013), Danen and colleagues of the Division of Toxicology of LACDR report novel insights into the question how stem cells decide to commit suicide when their DNA is damaged.
