Figure 3From: Hypoxia-inducible factor 1 alpha expression increases during colorectal carcinogenesis and tumor progression Cytosolic (A-C) and nuclear (D and E) HIF-1α expression profiles detected in colorectal carcinomas. With respect to the cytoplasmic expression intensity weak (A), moderate (B) and strong (C) immunoreactivity was detected. With respect to the nuclear expression intensity weak (D) and strong (E) immunoreactivity was seen.Back to article page
