{"doi":"10.1101/2022.12.15.520649","title":"Red Algae-Derived Mineral Intervention to Counter Pro-inflammatory Activity in Human Colon Organoids","abstract":"ABSTRACT Human colon organoids were maintained in culture medium alone or exposed to lipopolysaccharide with a combination of three pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-1β and interferon-γ [LPS-cytokines]) to mimic the environment in the inflamed colon. Untreated organoids and those exposed to LPS-cytokines were concomitantly treated with a multimineral product that has previously been shown to improve barrier structure/function. The organoids were subjected to proteomic analysis to obtain a broad view of the protein changes induced by these interventions. In parallel, confocal fluorescence microscopy and trans-epithelial electrical resistance measurements were used to assess barrier structure/function. The LPS-cytokines altered expression of multiple proteins that influence innate immunity and promote inflammation. Most of these were unaffected by the multi-mineral intervention, though a subset of inflammation-related proteins including fibrinogen-β and -γ chains, phospholipase A2 and SPARC was down-regulated in the presence of the multi-mineral intervention; another subset of proteins with anti-inflammatory, antioxidant or antimicrobial activity was up-regulated by multi-mineral treatment. When used alone, the multi-mineral intervention strongly up-regulated proteins that contribute to barrier formation and tissue strength. Concomitant treatment with LPS-cytokines did not inhibit barrier formation in response to the multimineral intervention. Altogether, the findings suggest that mineral intervention may provide a novel approach to combating inflammation in the colon by improving barrier structure/function as well as by directly altering expression of pro-inflammatory proteins.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2022,"id":313699,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9528,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":474221,"name":"Shannon D.
