Abstract
BACKGROUND Nasal polyposis, a chronic inflammatory disease affecting the upper airways, is a valuable and accessible model to investigate the mechanisms underlying chronic inflammation. The main objective of this study was to investigate a potential involvement of the unfolded protein response (UPR) in the context of oxidative stress and inflammation in nasal epithelial cells from nasal polyps (NP). METHODS Epithelial cells from NP (n = 20) and normal mucosa (Controls, n = 15) in primary culture were analyzed by global proteomic approach and cell biology techniques for the glucose-regulated protein 78 (GRP78), the spliced X-box-binding protein 1 (sXBP-1), the glucose-regulated protein 94 (GRP94), and the calreticulin (immunoblot, mass spectrometry, immunocytochemistry). RESULTS Proteomics analysis of human nasal epithelial cells in culture revealed the activation of the unfolded protein response in NP. Systematic cell biology and biochemical analysis of two markers (GRP78, sXBP-1) in the presence and absence of oxidative stress in NP showed a susceptibility of the unfolded protein response to oxidative stress compared to controls at least partially linked to an abnormal redox state of the protein disulfide-isomerase 4. This unfolded protein response was correlated with mitochondrial depolarization and secretion of interleukin 8 (IL-8) and leukotriene B4 (LTB4) and was prevented by mitochondrial antioxidant. CONCLUSIONS We show the existence of UPR in nasal epithelial cells that is linked to oxidative stress leading to IL-8 and LTB4 secretions. These mechanisms may participate in chronic inflammation in nasal polyposis.

Abstract
A host-vector system for inducible secretion during the logarithmic growth phase in Bacillus subtilis has been developed. The B. subtilis levansucrase gene promoter and the region encoding its signal sequence have been used. The endoglucanase A of Clostridium thermocellum was used as a model protein to test the efficiency of the system. Effective inducible secretion of the endoglucanase A was observed when either the levansucrase signal sequence or its own signal sequence was used. Expression of the endoglucanase A in different genetic backgrounds of B. subtilis showed that its regulation was similar to that of levansucrase, and high enzyme activity was recovered from the culture supernatant of a hyperproducing B. subtilis sacU(Hy) strain. The molecular weight of 46,000 estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis for the secreted endoglucanase A is compatible with the calculated molecular weight of the mature polypeptide.
