Salk scientists get to the root of plant cell fate

... polarity," he says. "But they have a very similar toolbox of genes to set up some aspects of their body plan." However, a critical difference between plants and animals in terms of polarity development is how much more tolerant plants are of manipulation. Long says, "In animals, early cell divisions are ve...

Interfering RNA silences genes in 'slippery' immune cells

...hort supply. We expect our technique to expand the toolbox for scientists doing research in immunology." RNA interference (RNAi), which naturally occurs in cells, is a process in which brief RNA sequences, called small interfering RNA (siRNA) block signals from a particular gene. This process, called gene s...

St. Jude study shows genes play an unexpected role in their own activation

...etermines which set of co-factor tools from CREB’s toolbox it will respond to.” In order to activate a gene, CREB must first get “tagged” by a molecule called phosphate. CREB then recruits a co-factor called CBP/p300 to the gene by binding to this protein at a site called KIX. Previously, scientists thou...
