The SERPINB4 gene mutation identified in twin patients with Crohn’s disease impaires the intestinal epithelial cell functions by Xiao-Mei Ouyang, Jun-Hui Lin, Ying Lin, Xian-Ling Zhao, Ya‐Ni Huo, Lai-Ying Liang, Yong-Dong Huang, Gui-Jing Xie, Peng Mi, Zhen-Yu Ye, Bayasi Guleng

“…Transcriptome sequencing revealed that the expression of genes encoding proinflammatory proteins (IL1B, IL6, IL17, IL24, CCL2, and CXCR2) and key proteins in the immune response (S100A9, MMP3, and MYC) was significantly upregulated during SERPINB4 mutant-induced apoptosis. Thus, the heterozygous SERPINB4 gene mutation causes the dysfunction of IECs, which would disrupt the intestinal epithelial barrier and contribute to the development of intestinal inflammation. …”

Debowski, Tiankuo Yang, Yalin Shen, Hans-Olof Nilsson, Stuart M. Haslam, Barbara Mulloy, Anne Dell, Keith A. Stubbs, Wolfgang Fischer, Rainer Haas, Hong Tang, Barry J. Marshall, Mohammed Benghezal

“…As LPS is a unique component of virtually all Gram-negative bacteria, our data suggest that when observing protein electrophoretic mobility shifts between wild-type and LPS mutant strains or between subcellular fractionation samples, the influence of LPS on protein electrophoretic migration should be considered first, rather than interpreting it as potential protein glycosylation that is dependent upon LPS biosynthetic pathway.…”
