pH-sensitive chitosan/sodium alginate/calcium chloride hydrogel beads for potential oral delivery of rice bran bioactive peptides.

Although rice bran active peptide (RBAP) has potent antioxidant properties, its practical applications have been limited by its low bioavailability. In this study, we hypothesized that pH-responsive hydrogels prepared from the ionic gelation between chitosan and alginate could be a promising delivery system of short-chain peptides, like RBAP, for protecting them from chemical degradation during digestion and improving their functionality. The hydrogel beads retained RBAP in the gastric environment due to strong interactions between two biopolymers and RBAP, followed by a sustained release of more than 70 % peptide in the intestinal condition, thus improving its gastrointestinal stability.

Single-Cell Secretome Profiling Enabled by Selective Enrichment and NanoLC-MS/MS Analysis.

Recent advances in single-cell proteomics enable the direct profiling of thousands of proteins from a single mammalian cell. However, due to the bottlenecks in detecting low-abundance secreted proteins and extracellular vesicle (EV) proteins (collectively referred to as the secretome) against a background of high-abundance proteins in serum-containing culture medium, the comprehensive investigation of the secretome at the single-cell level using nanoLC-MS/MS still remains challenging. Herein, we report a novel single-cell secretome profiling (SCSP) method by integrating the metabolic labeling of newly synthesized proteins, click chemistry-based enrichment, and in situ digestion of the labeled secretome in an alkyne-functionalized capillary micro-reactor, followed by nanoLC-MS/MS analysis.
