    Article Snippet: .. 28 In parallel, to assess the role of CREB in the molecular effects of galanin, vectors containing wild-type CREB, and two mutated variants of CREB (CREB133 and kCREB) were transiently transfected into MCCL using the nucleofector kit for primary epithelial cells and electroporated using the Amaxa Nucleofector II Device (Lonza, Walkersville, MD) before plating. .. Overexpression of CREB was assessed by immunoblotting using a total CREB antibody with β-actin used as a loading control, as described, 28 and CREB activity was assessed using the phospho-CREB DNA binding assay (Cayman Chemicals) after stimulation for 6 hours with 100 nmol/L Gal 1-29 or 10 μmol/L forskolin as a positive control.

An average of three independent experiments is shown. Error bars show ± SEM. ( D ) Western blots of ParC5 shNT, shδ110, and shδ680 cells immunoblotted with the indicated antibodies. ( E ) Densitometry of Western blots shown in D; expression of each protein of interest (POI) was normalized to the actin control. ( F ) ParC5 cells were transiently transfected with empty vector (pEV) or pPKCδFLAG for 48 hrs. Cells were then collected and immunoblotted with the indicated antibodies (First and second blots were probed with antibodies against PKCδ and FLAG-tag respectively). Note that panels D and F show two different experiments separated by lines, each normalized to their own β-actin loading control. ( G ) Densitometry of Western blots shown in F; expression of each POI was normalized to the actin control. Data are from three independent biological replicates and shown as mean ± SEM. Statistics represent two-way ANOVA with Dunnett’s multiple comparisons and Sidak’s multiple comparisons for (G) to the corresponding control (black bars). * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001.
