Mechanism of regulation of WAVE1-induced actin nucleation by Rac1 and Nck.

abstract：:Many homeobox genes are clustered in a linear array along a chromosome, reflecting their ordered expression along the anterior-posterior axis of the embryo. Expression patterns as well as grafting, ectopic expression and loss-of-function experiments suggest that the Hox genes encode a combinatorial system of positiona...

abstract：:The tumour suppressor p53 is required to induce programmed cell death (apoptosis) by DNA-damaging agents. As p53 is a transcriptional activator that mediates gene induction after DNA damage, it has been proposed to be a genetic switch that activates apoptosis-mediator genes. Here we evaluate the role of p53 in DNA-dam...
