(A) Western blots using total protein extract from N08-74 (control, TRIM3 expressed and Vector Control) and 13113 (control, TRIM3 expressed and Vector Control) shows that full-length NOTCH1 and active NOTCH1 (NICD) remain unchanged in their expression levels following the expression of TRIM3. (B,C,D,E,E1) Immunocytochemistry data shows TRIM3 expression enhances the nuclear localization of NICD in N08-74 glioma cells. (F,G) Western blot of NICD from cytosolic and nuclear extract supports the immunocytochemical data, showing that TRIM3 expression reduces NICD localization within the nucleus. R = 3 replicates. Scale bar: 5 um (B,C,D,E). VC = Vector Control.
