Fig. 1From: Clinicopathological implications of Tiam1 overexpression in invasive ductal carcinoma of the breastIHC staining of Tiam1 protein in breast cancer tissues. a Lack of Tiam1 protein staining in normal breast tissues. b Tiam1 protein was showed weakly positive in DCIS tissues. c Diffuse and strong positive expression of Tiam1 protein staining in breast cancer cells with LN metastasis (Luminal B). d Tiam1 was weakly positive in breast cancers with LN metastasis (Luminal B). e Lack of Tiam1 protein staining in breast cancers without metastasis (triple negative). f Tiam1 protein staining localized some nuclear staining was also observed in the metastatic breast cancers with lymphatic vessel invasion (triple negative).
