Special Issue Information

Dear Colleagues,

Carbohydrate, lipid and protein metabolism is an essential and complex biochemical reaction in the organism. With the help of enzymes, the three kinds of macronutrients involved varieties of digestion and absorption, synthesis and decomposition. The process of material processed into the body's needs guarantees the regular operation of the physiological function and is of great significance for health. Abnormal carbohydrate, lipid and protein metabolism profiles and changes can profoundly affect cell function, the immune system, antioxidant defenses, and inflammatory responses. The advent of new tools and information technologies have made it feasible to analyze entire glycomics, lipidomics, proteomics and metabolomics in biofluids and tissues. The determination of individual macronutrient characteristics (composition and abundance) in biosamples could be a powerful tool that can be used to understand the mechanisms of carbohydrate, lipid and protein-based diseases. The mechanisms that link carbohydrate, lipid and protein metabolism and metabolic syndrome have been studied, but remain not fully understood. We kindly invite investigators to contribute both original research and review articles that are in accordance with this Special Issue, which focuses on the role and mechanisms of carbohydrate, lipid and protein metabolism associate with related diseases, including obesity, diabetes, non-alcoholic fatty liver disease (NAFLD/NASH), atherosclerosis, hypertension, and coronary artery diseases. Subtopics that are also of interest include, but are not limited to, the followings:

  • The importance and application of carbohydrate, lipid and protein lipids in health and disease;
  • Carbohydrate, lipid and protein as diagnostic and prognostic biomarkers of disease;
  • Carbohydrate, lipid and protein in systems biology and metabolic networks;
  • New advances in carbohydrate, lipid and protein analysis and metabolomics.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.

A vital bioactive component of marine resources is Holothuria leucospilota polysaccharides (HLP). This study examined whether HLP could regulate intestinal flora to treat loperamide-induced constipation. Constipated mice showed signs of prolonged defecation (up by 60.79 min) and a reduced number of bowel movements and pellet water content (decreased by 12.375 and 11.77%, respectively). The results showed that HLP treatment reduced these symptoms, reversed the changes in related protein expression levels in the colon, and regulated the levels of active peptides associated with the gastrointestinal tract in constipated mice, which significantly improved water-electrolyte metabolism and enhanced gastrointestinal motility. Meanwhile, it was found that intestinal barrier damage was reduced and the inflammatory response was inhibited through histopathology and immunohistochemistry. As a means to further relieve constipation symptoms, treatment with low, medium, and high HLP concentrations increased the total short-chain fatty acid (SCFA) content in the intestine of constipated mice by 62.60 μg/g, 138.91 μg/g, and 126.51 μg/g, respectively. Moreover, an analysis of the intestinal flora’s gene for 16S rRNA suggested that the intestinal microbiota was improved through HLP treatment, which is relevant to the motivation for the production of SCFAs. In summary, it was demonstrated that HLP reduced loperamide-induced constipation in mice. Full article
