LMNA and familial dilated cardiomyopathy: Immunofluorescence staining against the cell membrane with WGA (red), specific antibodies against progerin (green, arrows) and nuclei (DAPI, blue) also revealed an increased expression of progerin protein in cell nuclei of DCM hearts (bright blue, merged image, arrows, Fig 4B), whereas healthy donor hearts did not reveal sustained progerin expression (Fig 4B, first line).
