Experimental details

Immunofluorescence analysis of KCNQ3 was performed using 70% confluent log phase RSC-96 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with KCNQ3 Rabbit Polyclonal Antibody (Product # PA1-930) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing membranous localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

Experimental details

Deletion of Afg3l2 in adult forebrain neurons causes tau hyperphosphorylation and activation of PKA and ERK 1/2 kinases Brain coronal sections of Afg3l2 forebrain neuronal specific knockout ( Afg3l2 fl/fl ; CamKIIalpha-Cre positive; NKO ) and littermate control ( Afg3l2 fl/fl ; CamKIIalpha-Cre negative, WT ) at 8 weeks of age were stained with Nissl solution. Pronounced neuronal degeneration is observed in the cerebral cortex and hippocampus. AT8 immunohistochemistry staining of adjacent sections from (A) shows accumulation of hyperphosphorylated tau in neuronal cell bodies in both cerebral cortex and hippocampus of Afg3l2 NKO . Western blot analysis of hippocampus and cerebral cortex lysates from Afg3l2 NKO and WT littermates using the indicated antibodies detects increased phosphorylation of tau. Western blot analysis of hippocampus and cerebral cortex lysates from Afg3l2 NKO and WT littermates using the indicated antibodies show activation of PKA and ERK1/2 kinases.
