Special Issue Information

Dear Colleagues,

With the development of science and technology, as well as the in-depth investigation of food chemicals and biological functions, more attention has been paid to the role of food in health promotion. Most acute and chronic diseases in humans are related to long-term unhealthy diets; therefore, studying the health-promoting effects of the bioactive ingredients of functional foods is of great significance. Using analytical chemistry, molecular biology, cell biology, histopathology and other technologies to study the interaction of functional food ingredients with organism biomacromolecules, gut microbiota, etc., can help us to further explore the mechanisms of active ingredients in the treatment and prevention of diseases (such as cancer, obesity, diabetes and cardiovascular disease) and in health promotion. Constructing targeted delivery systems to improve the bioavailability of functional food ingredients can also reveal the interaction mechanisms and health-promoting effects that occur with the organism at the molecular level, allowing precise nutritional intervention to be achieved.

Sea cucumber peptides have been proven to exhibit a variety of biological activities. Ulcerative colitis (UC) is a chronic disease characterized by diffuse inflammation of the mucosa of the rectum and colon with increasing incidence and long duration, and is difficult to cure. The effect of sea cucumber peptide on UC is currently unknown. In this study, 1.5% dextran sulfate sodium (DSS) was added to the drinking water of mice to induce a UC model, and the daily doses of sea cucumber peptide (SP) solution of 200 mg/kg·BW, 500 mg/kg·BW, and 1000 mg/kg·BW were given to UC mice to detect the relieving effect of SP. The results showed that SP can reduce the disease activity index (DAI) of UC mice induced by DSS and can alleviate colon shortening, intestinal tissue damage, and the loss of intestinal tight junction proteins (Claudin-1, Occludin). SP decreased the spleen index, pro-inflammatory factors (IL-1β, IL-6, TNF-α), and myeloperoxidase (MPO) levels in UC mice. SP can alleviate the imbalance of gut microbiota in UC mice, increase the abundance of the Lachnospiraceae NK4A136 group, Prevotellaceae UCG-001, and Ligilactobacillus, and reduce the abundance of Bacteroides and the Eubacterium rum group, as well as alleviating the decrease in short-chain fatty acid (SCFA) content in the feces of UC mice. Notably, SP inhibited miR-155 expression in the colon tissue of UC mice and increased its target protein, suppressor of cytokine signaling 1 (SOCS1), which acts as an inflammatory inhibitor. In summary, the ameliorative effect of SP on UC may be achieved by improving the imbalance of gut microbiota and regulating the miR-155/SOCS1 axis. This study provides a new idea for developing SP as a nutritional supplement to maintain intestinal health. Full article
