Abstract
The flexible and controlled synthesis of metal-organic framework (MOF)-derived hybrid nanostructures is of great significance in fine tuning of their enrichment performance in large-scale and in-depth phosphoproteome analysis. Herein, a magnetic guanidyl-functionalized MOF hybrid coating with multiaffinity sites, denoted as Fe3O4@G-ZIF-8, was fast fabricated via a one-pot epitaxial growth strategy for the first time and applied for selective and highly efficient enrichment of global phosphopeptides. The intrinsic unsaturated metal sites of ZIF-8 endow the surface-mounted MOF coatings with immobilized metal ion affinity chromatography interaction with multiphosphorylated peptides. The oriented anchoring of bifunctional guanidineacetic acid on the magnetic MOF nanospheres provides additional affinity sites (guanidyl groups) for specific recognition of phosphopeptides by "salt bridge" interaction, as well as active site carboxyl groups for the coordination with the metal ions. The as-prepared Fe3O4@G-ZIF-8 exhibits large surface area (382.5 m2 g-1), good superparamagnetic property (41.6 emu g-1) and stability, and size-exclusion effect (1.73 nm), which can serve as a specific adsorbent for global phosphopeptide analysis with satisfactory selectivity, great detection sensitivity (1 fmol), and rapid magnetic separation. Moreover, the successful application of Fe3O4@G-ZIF-8 for selective capture of both multi- and mono-phosphopeptides from human saliva and serum demonstrated the great potential of magnetic surface-mounted MOF coatings in effective identification of low-abundance phosphopeptides by matrix-assisted laser desorption ionization time-of-flight mass spectrometry from complicated biological matrices.

Abstract
Casein phosphopeptide (CPP) has been widely used as micronutrient supplementation for certain populations. However, its solubility performance is far from satisfying. In this work, instant CPP powders with micropore structures were fabricated by supercritical fluid-assisted atomization (SAA) using supercritical CO2 fluid (SC-CO2) as an atomizing agent. The effects of the processing parameters (temperature, time, and pressure) on SC-CO2 absorption rate and dissolution rate were systematically evaluated and studied. The viscosity of the CPP solution increased with increased pressure of SC-CO2 as pressure increased its solubility. The processing conditions are optimized as follows: 40 °C, 40 min, and 8.27 MPa, with an SC-CO2 absorption rate of about 8 wt.%. The dissolution time of the SAA-CPP powders was significantly decreased from 1800 s to 54 s at room temperature, due to the micropore structures and almost 10 times increase in the specific surface area of SAA-CPP. The bioactivities of the instant SAA-CPP, especially the calcium-binding capacity, were also evaluated and showed no observable difference. Among the four CPPs prepared in different ways in this work, SAA-CPP had better dissolution performance. The results show that SAA technology is a promising way to prepare instant polypeptide powders.

Poult Sci 2021; 100:527-536.

Abstract
Phosvitin (PV) from egg yolk is an excellent substrate for the production of phosphopeptides, which have a strong calcium chelating capacity and promoting calcium absorption and bone mineralization. This study investigated the effect of PV hydrolysates produced using a effective preparation method (high temperature (121°C) and mild pressure (0.1 MPa), HTMP) or HTMP pretreatment and trypsin hydrolysis combination (HTMP-PV18) on the physiology of an osteoblast MC3T3-E1 cells line. The proliferation, apoptosis, and differentiation of MC3T3-E1 cells were analyzed using the CCK-8, flow cytometry, and RT-PCR reactions, respectively. Both the HTMP-PV and HTMP-PV18 increased the proliferation, and inhibited the apoptosis of MC3T3-E1 cells significantly. The HTMP-PV increased the proliferation of MC3T3-E1 cells by 147.12 ± 2.11% and the HTMP-PV18 by 136.43 ± 4.51%. In addition, the HTMP-PV and HTMP-PV18 effectively promoted the expression of genes related to the OPG/RANKL signaling channel during cell differentiation. This indicated that both the HTMP-PV and HTMP-PV18 have the potential to promote bone mineralization by improving the proliferation and differentiation of osteoblastic cells.

Abstract
In our continuous searching for natural active polysaccharides with immunomodulatory activity, an arabinofuranan (AQP70-3) was isolated and purified from the fruits of Akebia quinata (Houtt.) Decne. by using ion-exchange chromatography and gel permeation chromatography for the first time. AQP70-3 contained both α-l-Araf and β-l-Araf, and the absolute molecular weight was 1.06 × 104 g/mol. The backbone of AQP70-3 comprised →5)-α-l-Araf-(1→, →3,5)-α-l-Araf-(1→, and →2,5)-α-l-Araf-(1→, with branches of →1)-β-l-Arafand →3)-α-l-Araf-(1→ residues. Biological assay suggested that AQP70-3 can stimulate phagocytic activity and promote the levels of nitric oxide (NO), interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α) of RAW264.7 cells. Furthermore, AQP70-3 was found to increase the production of reactive oxygen species (ROS) and NO in zebrafish embryo model.

Abstract
The effect of high-temperature and mild-pressure (HTMP) pretreatment on the enzymatic hydrolysis of phosvitin and the structural characteristics of the phosphopeptides produced were analyzed using tandem mass spectrometry. The HTMP pretreatment hydrolyzed phosvitin at random sites and helped the subsequent enzyme hydrolysis of the peptides produced. With the HTMP pretreatment alone, 154 peptides were produced, while the use of trypsin, Protex 6L, and Multifect 14L in combination with the pretreatment produced 252, 280, and 164 peptides, respectively. The use of two enzyme combinations (trypsin + Protex 6L and trypsin + Multifect 14L) helped the hydrolysis further. The number of phosphopeptides produced increased when the modifications within the same amino acid sequences were considered. This study indicated that HTMP pretreatment was a breakthrough method to improve the enzymatic hydrolysis of phosvitin that enabled an easy production of phosvitin phosphopeptides for their subsequent functional characterizations.
