... exogenous insults (e.g. excitotoxins, stroke) is promoted by an extracellular cascade involving the serine protease tissue plasminogen activator (tPA). However, whether it is through necrotic or apoptotic mechanisms that this excitotoxic cell death occurs has remained contested. We describe the attenuation...

... of some early markers of differentiation, tissue-type plasminogen activator (tPA), AFP and keratins 8 and 19 is inhibited, whilst brachyury and myosin are increased, in clones containing kinase-negative mutant EGFR. After an extended period of differentiation, the cell types present in mutant and control...

... cells in the gastric region subjacent to the tentacles. Treatment with the protein kinase C activator 12- O -tetradecanoylphorbol-13-acetate (TPA) causes a rapid increase in the level of ks1 mRNA in head-specific epithelial cells and also induces ectopic ks1 expression in cells of the gastric region...

..., acetylcholine receptor and, in the case of limb cells, fusion into multinucleated myotubes. When the tumour promoter 12- O -tetradecanoyl phorbol 13-acetate (TPA) was added to these cultures, it caused differential effects, depending upon the age of the embryo from which cells were isolated. In cultures...
