Inhibitor of κB (IκB) β (IκBβ) represents one of the major primary regulators of NF-κB in mammals. In contrast to the defined regulatory interplay between NF-κB and IκBα, much less is known about the biological function of IκBβ. To elucidate the physiological role of IκBβ in NF-κB signaling in vivo, we generated IκBβ-deficient mice.

Epidemiological and experimental data demonstrate, that inflammation contributes significantly to pancreatic carcinogenesis. IL1beta, a pleiotropic cytokine produced by inflammatory cells and tumor cells, promotes cancer progression. Single nucleotide polymorphisms (SNPs) of the IL1beta promoter were found to be associated with an increased risk for certain cancers.

The integrated stress response (ISR) integrates a broad range of environmental and endogenous stress signals to the phosphorylation of the alpha-subunit of eukaryotic translation initiation factor 2 (eIF2 alpha). Although intense or prolonged activation of this pathway is known to induce apoptosis, the molecular mechanisms coupling stress-induced eIF2 alpha phosphorylation to the cell death machinery have remained incompletely understood. In this study, we characterized apoptosis initiation in response to classical activators of the ISR (tunicamycin, UVC, elevated osmotic pressure, arsenite).
