Table 1 IHC analysis of Vav3 expression in breast cancer specimens.

From: Vav3 oncogene activates estrogen receptor and its overexpression may be involved in human breast cancer

Differentiation Staining intensity Intensity (>1)
  Negative 1–2 3–4  
Well to moderate 8 22 5 27/35
Poor 0 2 6 8/8
Normal breast tissue 8 0 0 0/8
Normal vs. tumor p < 0.0001
Well to moderate vs poor differentiation p > 0.05
  1. Differences in the IHC staining of surgical specimens of human breast cancer were analyzed with the chi-square test.
