dc.description.abstract | Lipopolysaccharide (LPS) is associated with chronic intestinal inflammation and promotes intestinal cancer progression in the gut. While the interplay between LPS and intestinal immune cells has been well characterized, little is known about LPS and intestinal epithelium interactions. In this study, we explored the differential effect of LPS on proliferation and the transcriptome in 3D enteroids/colonoids obtained from dogs with naturally occurring gastrointestinal (GI) diseases, such as Inflammatory Bowel Disease (IBD) and GI mast cell tumor. The study objective was to analyze LPS-induced modulation of signaling pathways involving the intestinal epithelia and critical to colorectal cancer development in the context of IBD or a tumor microenvironment. While LPS incubation resulted in a pro-cancer gene expression pattern and stimulated proliferation of IBD enteroids and colonoids, down-regulation of several cancer-associated genes like CRYZL1, Gpatch4, SLC7A1, ATP13A2, and ZNF358 was also observed in tumor enteroids. Genes participating in porphyrin metabolism (CP), thiamine and purine metabolism (TAP2, EEF1A1), arachidonic acid, and glutathione metabolism (GPX1) exhibited a similar pattern of altered expression between IBD enteroids and IBD colonoids following LPS stimulation. In contrast, genes involved in anion transport, transcription and translation, apoptotic processes, and regulation of adaptive immune responses showed opposite expression patterns between IBD enteroids and colonoids following LPS treatment. In brief, the cross-talk between LPS/TLR4 signal transduction pathway and several metabolic pathways, such as fatty acid degradation and biosynthesis, and purine, thiamine, arachidonic acid, and glutathione metabolism, may be important in driving chronic intestinal inflammation and intestinal carcinogenesis. | |
