Functional PAK-2 knockout and replacement with a caspase cleavage-deficient mutant in mice reveals differential requirements of full-length PAK-2 and caspase-activated PAK-2p34.

p21-Activated protein kinase 2 (PAK-2) has both anti- and pro-apoptotic functions depending on its mechanism of activation. Activation of full-length PAK-2 by the monomeric GTPases Cdc42 or Rac stimulates cell survival, whereas caspase activation of PAK-2 to the PAK-2p34 fragment is involved in the apoptotic response. In this study we use functional knockout of PAK-2 and gene replacement with the caspase cleavage-deficient PAK-2D212N mutant to differentiate the biological functions of full-length PAK-2 and caspase-activated PAK-2p34.

The practice of clinical research in accredited marriage and family therapy programs.

This study aims to explore the prevalence of clinic-based research among accredited marriage and family therapy (MFT) programs and reveal rationales explaining why academic settings may or may not be conducting clinical research. Findings of this project are the result of electronic-mail surveys completed by 26 accredited MFT programs. Approximately one-half of the respondents reported currently conducting clinic-based research.
