The KH-type splicing regulatory protein (KSRP) promotes the decay of AU-rich element (ARE) containing mRNAs. Although KSRP is expressed in the developing and mature nervous system, very little is known about its role in regulating gene expression in the brain. In this study, we utilized in vitro binding and decay studies to examine whether KSRP regulates the stability of the GAP-43 transcript, ...

BACKGROUND AND PURPOSE An objective of therapeutic intervention after cerebral ischemia is to promote improved functional outcome. Improved outcome may be associated with a reduction of the volume of cerebral infarction and the promotion of cerebral plasticity. In the developing brain, neuronal growth is concomitant with expression of particular proteins, including microtubule-associated protei...

Suppression of gap-junctional communication by various protein kinases, growth factors, and oncogenes frequently correlates with enhanced mitogenesis. The oncogene v -src appears to cause acute closure of gap junction channels. Tyr265 in the COOH-terminal tail of connexin 43 (Cx43) has been implicated as a potential target of v -src , although v -src action has also been associated with changes...
