Colonic mucus is a key element of colonic barrier as it is located at the frontier between luminal microflora and colonic mucosa itself. Colonic mucus is mainly composed of high molecular weight glycoproteins called mucins that can be either secreted or membrane-linked. The expression of various colonic mucins is altered in colorectal cancers or inflammations. The aim of this review is to highlight the crucial role played by colonic mucins in the maintenance of colonic barrier integrity, both because they are part of the protective mucus layer, and because they individually exert specific functions involved in epithelial barrier, like cell growth and differentiation, immunomodulation, signal transduction or cell adhesion.

Increasing evidence suggests that dysbiosis of gut microbiota exacerbates chronic kidney disease (CKD) progression. Curcumin (CUR) has been reported to alleviate renal fibrosis in animal models of CKD. However, the relationship between CUR and gut microbiome in CKD remains unclear.

Oral antibiotic treatment is well known to be one of the main factors affecting gut microbiota composition by altering bacterial diversity. It decreases the abundance of butyrate-producing bacteria such as Lachnospiraceae and Ruminococcaceae, while increasing abundance of Enterobacteriaceae. The recovery time of commensal bacteria post-antibiotic treatment varies among individuals, and often, complete recovery is not achieved.

Despite the WHO recommendations in favor of breastfeeding, most infants receive infant formulas (IFs), which are complex matrices involving numerous ingredients and processing steps. Our aim was to understand the impact of the quality of the protein ingredient in IFs on gut microbiota and physiology, blood metabolites and brain gene expression. Three IFs were produced using whey proteins (WPs) from cheese whey (IF-A) or ideal whey (IFs-C and -D) and caseins, either in a micellar form (IFs-A and -C) or partly in a non-micellar form (IF-D).

Colitis-associated colorectal cancer (CAC), a serious complication of ulcerative colitis (UC), is associated with a poor prognosis. The vitamin D receptor (VDR) is recognized for its protective role in UC and CAC through the maintenance of intestinal barrier integrity and the regulation of inflammation. This study demonstrates a significant reduction in mA-related genes, particularly methyltransferase like 14 (METTL14), in UC and CAC patients and identifies an association between METTL14 and VDR.
