From: NQO1 protein expression predicts poor prognosis of non-small cell lung cancers
IHC staining for NQO1 protein expression in lung tissues. (A) NQO1 protein was negative in normal lung tissues. (B) NQO1 protein was showed diffuse and strong positive staining in cytopalsm of lung SCC cells with LN metastasis. (C) NQO1 was weakly positive in lung SCC without LN metastasis. (D) Diffuse and strong positive NQO1 protein signal in lung adenocarcinoma. (E & F) NQO1 protein staining is negative or weakly positive in lung adenocarcinoma. (Original magnification, 200× in A-F).
