Immunohistochemical detection of filamin A (FLNA) in somatotropinomas. Representative images of FLNA immunohistochemical scores in somatotropinomas at 400X magnification: (A) Score-0: no membrane or cytoplasmic immunoreactivity; (B) Score 1: low membrane and cytoplasmic immunoreactivity; score 2: moderate membrane and cytoplasmic immunoreactivity; Score 3: high membrane and cytoplasmic immunoreactivity. Scale bar: 100 µm. In addition, negative (E) and positive (F) controls of the IHC validation are represented using a FFPE-uterus sample. (G) Correlation between FLNA IHC-staining and mRNA levels).
