  • * The molecular weight of FVPA1 is approximately 1.8 × 10^4 Da, determined through advanced chromatography techniques, and its structural details were uncovered using various analytical methods.
  • * Laboratory tests show that FVPA1 can notably improve the activity of natural killer cells against K562 tumor cells, suggesting its potential in cancer treatment or prevention.

Article Abstract

FVPA1, a novel polysaccharide, has been isolated from fruiting bodies of the culinary-medicinal mushroom Flammulina velutipes, a historically popular, widely cultivated and consumed functional food with an attractive taste, beneficial nutraceutical properties such as antitumor and immunomodulatory effects, and a number of essential biological activities. The average molecular weight was estimated to be ~1.8 × 104 Da based on high-performance size exclusion chromatography. Sugar analyses, methylation analyses, and 1H, 13C, and 2-dimensional nuclear magnetic resonance spectroscopy revealed the following structure of the repeating units of the FVPA1 polysaccharide Identification of this structure would conceivably lead to better understanding of the nutraceutical functions of this very important edible fungus. Bioactivity tests in vitro indicated that FVPA1 could significantly enhance natural killer cell activity against K562 tumor cells.

Introduction: Oxidative stress, triggered by an imbalance between reactive oxygen species (ROS) production and cellular antioxidant defense mechanisms, is implicated in various pathological conditions. Plant-derived polysaccharides have gained significant attention as potential natural antioxidants due to their biocompatibility, biodegradability, and structural versatility.

Methods: This study focuses on the purification, structural characterization, and antioxidant activities of a novel pectin polysaccharide (HFPS) isolated from the flowers of Linn.

Lactoferrin protein (LF) is a natural protein with certain emulsifying ability, but is sensitive to be affected by environmental factors and has poor oxidative stability to be used as emulsifier. In this study, the emulsifying ability of LF was significantly improved after conjugation with Rosa roxburghii Tratt fruit polysaccharides (RTFP), and the emulsion stability mechanism of LF-RTFP conjugates (L-R) were elucidated through the utilization of CLSM (confocal laser scanning microscopy), interfacial tension, apparent viscosity, and protein adsorption rate. The emulsion stabilized by L-R showed the smaller particle size (17.

Intestinal barrier damage causes an imbalance in the intestinal flora and microbial environment, promoting a variety of gastrointestinal diseases. This study aimed to explore the mechanism by which adipose-derived stem cells (ADSCs) repair intestinal barrier damage. The human colon adenocarcinoma cell line Caco-2 and rats were treated with lipopolysaccharide (LPS) to establish in vitro and in vivo models, respectively, of intestinal barrier damage.

Three chondroitin sulfate (CS) analogues with predominant subtypes (A, C, and E) were prepared from engineered K4 combined with regioselective sulfation. CS with the designed sulfates as the main components was characterized by nuclear magnetic resonance spectroscopy, elementary analysis, and disaccharide analysis. CS prepared from the native or degraded capsular polysaccharide had molecular weights of 1.
