We examined the expression of HIF1α, STAT3, and C/EBPβ in tumor cell line (SCCL-MT1 or USC-HN2)-induced CD33+ or (MCF7 breast or NCI-H60 small cell lung carcinoma) CD11b+ human suppressor cells compared with medium only controls by qRT-PCR techniques (data from six unique donors, two independent experiments) (Figure 8A) and immunohistochemistry (Figure 8B). The gene discussed is STAT3; the disease is neoplasm.
