Pathogenesis of inflammatory bowel disease: transcription factors in the spotlight.

1998

See article on page 477 Dysregulated cytokine production by mucosal lymphocytes and macrophages has been implicated in the pathogenesis of both Crohn’s disease and ulcerative colitis, the two major forms of human inflammatory bowel disease (IBD).1 Over the past few years, various murine models of chronic intestinal inflammation resembling IBD have been discovered which have provided important clues as to the nature of this dysregulation and to its possible treatment with cytokines.2 Thus, in studies of several of the models most closely resembling Crohn’s disease it has been shown that production of large amounts of Th1-type cytokines—for example, interferon γ, by T cells is a major and ess…

Oncolytic targeting of renal cell carcinoma via encephalomyocarditis virus

2010

Apoptosis is a fundamental host defence mechanism against invading microbes. Inactivation of NF-kappaB attenuates encephalomyocarditis virus (EMCV) virulence by triggering rapid apoptosis of infected cells, thereby pre-emptively limiting viral replication. Recent evidence has shown that hypoxia-inducible factor (HIF) increases NF-kappaB-mediated anti-apoptotic response in clear-cell renal cell carcinoma (CCRCC) that commonly exhibit hyperactivation of HIF due to the loss of its principal negative regulator, von Hippel-Lindau (VHL) tumour suppressor protein. Here, we show that EMCV challenge induces a strong NF-kappaB-dependent gene expression profile concomitant with a lack of interferon-me…
