Immunofluorescence studies performed in different types of human cells, including primary dermal fibroblasts (HDFs), embryonic kidney HEK‐293T cells, and breast adenocarcinoma MDA‐MB‐231 cells, revealed a co‐localization between lamin A and GFP–Smurf2, in particular at the nuclear envelope (Figure 1c,d, upper panels, and Figure S1a,b). The gene discussed is SMURF2; the disease is breast adenocarcinoma.
