Figure 1From: Depletion of the actin bundling protein SM22/transgelin increases actin dynamics and enhances the tumourigenic phenotypes of cellsExpression and localization of transgelin family proteins in REF52 cells. A, western blot analysis of SM22, NP25 and NP22 levels in various cell lines as indicated (S3T3 = Swiss 3T3). REF52 cells were chosen for further analysis due to their amenable phenotype and the expression of only SM22α. B-G, REF52 cells stained with Alexa 488 phalloidin (red in merge) to reveal F-actin containing structures (B, E), and stained for endogenous SM22α (C), or expressing SM22α-GFP (F) green in merges. Merged images (D, G) all show strong co-localization between endogenous and exogenous SM22 proteins and F-actin stress fibres. Nucleus counterstained with DAPI (blue).Back to article page
