CASP2 knockdown protects DRGN and DRG glia from apoptosis induced by serum withdrawal.

<p><b><i>A</i></b>, Western blot and <b><i>B</i></b>, subsequent densitometry to show CASP2 and CASP3 protein levels after knockdown with relevant siRNA. <b><i>C</i></b>, and <b><i>D</i></b>, Immunocytochemistry to demonstrate CASP2 and CASP3 knockdown in DRGN and satellite cells by relevant siRNA, respectively. <b><i>E</i></b>, Quantification of DRGN and <b><i>F</i></b>, DRG glia survival after siRNA-mediated knockdown of CASP2 and CASP3. Scale bars in <i>C</i> and <i>D</i> = 50 µm.
