(A) Association between transcript and protein (1+, 2+, and 3+) expression levels; (B) Correlation between transcript expression level and amplification (2–5 copies and >10 copies or large clusters); (C) CISH, IHC and qRT-PCR results in 37 samples of breast cancer. The samples are indicated in dark circles. The transcript expression values by qRT-PCR are indicated in a log scale. Bars indicate the median value. P values are shown.
