Interferon regulatory factor‐1 is prerequisite to the constitutive expression and IFN‐γ‐induced upregulation of B7‐H1 (CD274)
9 Jan 2006
Abstract excerpt
Majority of cancer cells upregulate co-inhibitory molecule B7-H1 which confers resistance to anti-tumor immunity, allowing cancers to escape from host immune surveillance. We addressed the molecular mechanism underlying the regulation of cancer-associated B7-H1 expression in response to interferon-gamma (IFN-gamma). Using promoter constructs in luciferase assay, the region between 202 and 320 bp from the...
