Selective genetic deletion of cacna1c in the mouse prefrontal cortex

The image illustrates the elimination of Cav1.2 protein, encoded by the cacna1c gene, in the mouse prefrontal cortex (PFC) using adenoassociated viral (AAV) vector-expressing Cre recombinase (AAV-Cre). Cacna1c was focally eliminated in the PFC via bilateral stereotactic delivery of AAV-Cre (right panel) into the PFC of floxed cacna1c mice.1 AAV-expressing green fluorescent protein (AAV-GFP) was used as a control, as shown in the left panel. Double immunohistochemical analysis was used to visualize GFP (green; top left image) and Cav1.2 (red; bottom left image) protein using anti-GFP and anti-Cav1.2 (ref. 2) antibodies, respectively. The larger left image displays co-localization of GFP and Cav1.2 (blue arrows), indicating that AAV-GFP did not alter levels of Cav1.2.

 The right panel shows loss of Cav1.2 protein selectively in the PFC after delivery of AAV-Cre. As AAV-Cre also expresses GFP, viral spread can be readily visualized through immunohistochemical detection of GFP (green; top right image). Co-labeling with anti-Cav1.2 antibody identifies Cav1.2 protein (red; bottom right image). The larger image in the right panel shows the absence of Cav1.2 labeling in regions expressing GFP (green), indicating focal deletion of cacna1c by AAV-Cre. c.c., corpus callosum.
