Abstract
Exosomes, which can be used to investigate various disease processes, are novel disease markers that have been extensively studied in recent years. In this work, zirconium-rich porphyrin-based porous organic polymers (Imi-Pops-Zr) were synthesized by a facile and low-cost strategy for specific enrichment and isolation of phosphorylated peptides and exosomes. The proposed material demonstrates a low detection limit (0.5 fmol), a high selectivity (bovine serum albumin (BSA): β-casein = 1000:1), and a loading capability of 100 mg/g for phosphopeptides. For complex practical samples, after enrichment with Imi-Pops-Zr, 4 characteristic phosphopeptides from human serum, 20 and 12 phosphopeptides from human saliva and defatted milk were detected, respectively. Besides, 74 phosphorylated peptides with 67 phosphorylation sites belonging to 61 phosphoproteins and 67 phosphorylated peptides with 63 phosphorylation sites belonging to 65 phosphoproteins were detected from the serum of normal controls and uremic patients, respectively. Biological processes, cellular components and molecular functions revealed that interleukin-6, tumor necrosis factor, high density lipoprotein and proteases binding may be associated with uremia. Furthermore, Imi-Pops-Zr was successfully used to enrich and isolate exosomes from human serum. The experimental results show that Imi-Pops-Zr has promising application in the specific enrichment of phosphorylated peptides and exosomes in complex bio-samples.

Abstract
A green strategy was developed to prepare carbonaceous spheres rich in phosphoric acid groups on the surface with D-Glucose 6-phosphate sodium salt (called G6PNa2) as a sole carbon source through one-step hydrothermal carbonization method. The method is simple and facile and meets the standards of green chemistry as water is the sole solvent employed. Following the hydrothermal carbonization synthesis, the carbonaceous spheres were further functionalized with Ti4+. The main factors including reaction temperature, reaction time, and concentration of G6PNa2 were systematically studied in order to obtain the desirable morphology and the optimum phosphopeptides enrichment, for the resulting Ti4+ functionalized carbonaceous spheres (CS-Ti4+). The performance evaluation of the CS-Ti4+ prepared under the optimum conditions demonstrated excellent selectivity (1:1000), low detection limit (1 fmol) and high recovery rate (85%) towards phosphopeptides. Furthermore, 24 low-abundance phosphopeptides were captured from human saliva using CS-Ti4+, indicating its great potential in mass spectrometry-based phosphoproteome studies.

Abstract
Understanding the cellular processes is central to comprehend disease conditions and is also true for cancer research. Proteomic studies provide significant insight into cancer mechanisms and aid in the diagnosis and prognosis of the disease. Phosphoproteome is one of the most studied complements of the whole proteome given its importance in the understanding of cellular processes such as signaling and regulations. Over the last decade, several new methods have been developed for phosphoproteome analysis. A significant amount of these efforts pertains to cancer research. The current use of powerful analytical instruments in phosphoproteomic approaches has paved the way for deeper and sensitive investigations. However, these methods and techniques need further improvements to deal with challenges posed by the complexity of samples and scarcity of phosphoproteins in the whole proteome, throughput and reproducibility. This review aims to provide a comprehensive summary of the variety of steps used in phosphoproteomic methods applied in cancer research including the enrichment and fractionation strategies. This will allow researchers to evaluate and choose a better combination of steps for their phosphoproteome studies.

Abstract
Extracellular vesicles (EVs) are attracting increasing interest with their intriguing role in intercellular communications. Protein phosphorylation in EVs is of great importance for understanding intercellular signaling processes. However, the study of EV phosphoproteomics is impeded by their relatively low amount in limited clinical sample volumes, and it is necessary to have a sensitive and efficient enrichment method for EV phosphopeptides. Herein, a novel Ti(IV)-functionalized and glass fiber-supported hybrid monolithic spin tip, termed PhosTip, was prepared for enriching phosphopeptides from urinary EVs. Glass fiber as the stationary phase positions the hybrid monolith in a standard pipet tip and prevents the monolith from distortion during experiments. The preparation procedure for the new PhosTip is simple and time-saving. The hybrid monolithic PhosTip provides excellent enrichment efficiency of low-abundance phosphopeptides from cell digests and urinary EVs with minimum contamination and sample loss. Using the PhosTip, we demonstrate that 5373 and 336 unique phosphopeptides were identified from 100 and 1 μg of cell lysates, while 3919 and 217 unique phosphopeptides were successfully identified from 10 and 1 mL of urinary samples, respectively. The PhosTip was finally applied to enrich phosphopeptides in urine EVs from prostate cancer patients and healthy controls and quantify 118 up-regulated proteins with phosphosites in prostate cancer samples. These results demonstrated that the PhosTip could be a simple and convenient tool for enriching phosphopeptides from clinical samples and for broader applications in biomarker discovery.

Abstract
Pingyangmycin (PYM) and boanmycin (BAM), two individual components of bleomycin (bleomycin A5 and bleomycin A6), are glycopeptide antitumor antibiotics. An efficient procedure for the preparation of PYM and BAM from Streptomyces verticillus var. pingyangensis fermentation broth using macroporous cation-exchange (MCE) resin followed by medium-pressure preparative liquid chromatography (MPLC) based on monodisperse poly(styrene-co-divinylbenzene) (p(st-dvb)) microspheres was investigated in this paper. Nine frequently used MCE resins were screened by static adsorption and desorption to enrich PYM and BAM fromthe fermentation broth, and D157 resin was found to be the most effective. After one run of column-based dynamic adsorption and desorption, the contents of PYM and BAM were increased by factors of 13.8 and 12.1 with recovery yields of 84.21% and 81.47%, respectively. The enriched samples were subjected to MPLC with columns prepacked with the PolyRP 10-300 microspheres. The operational parameters of the MPLC, including the stationary phase and mobile phase compositions, sample/stationary phase ratio, sample loading scale and flow rate, were screened and optimized. The results showed that the separation and purification for PYM and BAM by MPLC were dramatically improved with a mobile phase modifier of 0.15 mol/L ammonium chloride aqueoussolution, a flow rate of 10 mL/min and a sample/stationary phase ratio of 1.0:100 (m/v, g/mL), and PYM and BAM with purities of more than 98.65% and 99.12% were obtained, respectively. The total recoveries of PYM and BAM reached 75.38% and 70.31%. The separation and purification method is simple, efficient, energy-saving, environmentally friendly and suitable for the large-scale preparation of high-purity PYM and BAM from Streptomyces verticillus var. pingyangensis fermentation broth.

Abstract
In this study, a titanium ion (Ti4+) functionalized polydopamine coated ferroferric oxide (Fe3O4@PDA@Ti4+) core-shell magnetic particle was prepared for the selective extraction of nucleotides. Firstly, different metal ions including Ti4+, Zr4+, Fe3+, Al3+, Cu2+, Zn2+, Ni2+ and Mg2+ were respectively immobilized onto Fe3O4@PDA particles and their extraction efficiency for five nucleotides [cytidine-5'-monophosphate (CMP), uridine-5'-monophosphate (UMP), guanosine-5'-monophosphate (GMP), thymidine-5'-monophosphate (TMP) and adenosine-5'-monophosphate (AMP)] were compared. Among these prepared materials, Fe3O4@PDA@Ti4+, which exhibited the highest extraction efficiency for nucleotides, was further characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy. After being optimized of the extraction parameters including adsorbent amounts, extraction time, extraction temperature, type and concentration of the eluent, the prepared Fe3O4@PDA@Ti4+ magnetic particles were successfully applied for the selective extraction and determination of CMP, UMP, GMP, TMP and AMP in Cordyceps and Lentinus edodes. Good linearity (varying from 0.063 to 19.000 μg/mL, R2 > 0.999) and low limit of detection (LODs) (ranging between 0.0047 and 0.0141 μg/mL) for target analytes were achieved. These results demonstrated that the synthesized material in this study had potential for selective extraction of phosphorylated small molecular compounds in complicated matrix.

Abstract
Hierarchically porous monoliths as a key feature of biological materials have been applied in enrichment and separation. In this work, a metal immobilized hierarchically porous organosilica hybrid monolith was synthesized by hydrolysis and condensation of tetraethoxysilane (TEOS) and diethoxyphosphorylethyl-triethoxysilane (DPTS) under alkaline environment. Phosphonate ester groups were firstly introduced by the employment of DPTS as functional monomer, and then acidified to phosphonic acids. The surface area of optimal monolith could reach to 1170 m2/g, which simultaneously contained micropores and mesopores (4 nm) obtained from nitrogen sorption measurement. Meanwhile, mercury intrusion porosimetry (MIP) further demonstrated that macropores (1-3 μm) existed in monoliths. Followed by chelating with titanium ion (Ti4+), the hierarchically porous organosilica hybrid monoliths could be applied as IMAC materials. This synthesized process was easy-operating and time-saving, and avoided the tedious and complex process of traditional Ti4+-IMAC materials. Furthermore, the Ti4+-IMAC monoliths exhibited high adsorption capacity for pyridoxal 5'-phosphate (82.6 mg/g). The 3282 unique phosphopeptides could be identified from 100 μg of HeLa digests after enrichment with the monolith, exhibiting excellent enrichment performance of low-abundance phosphopeptides.

Abstract
Analysis of phosphoproteins always faces the challenge of low stoichiometry, which demands highly selective and efficient enrichment in the initial sample preparation. Here we report our synthesis of the novel titanium (IV) ion immobilized adenosine triphosphate functionalized silica nanoparticles (Ti4+-ATP-NPs) for efficient enrichment of intact phosphoproteins. The average diameter of Ti4+-ATP-NPs was about 128 nm with good dispersibility and the saturated adsorption capacity for β-casein was 1046.5 mg/g. In addition, Ti4+-ATP-NPs exhibited high specificity and selectivity in enriching phosphoproteins from both standard protein mixtures and complex biological samples (non-fat milk, chicken egg white and mouse heart tissue extract) as demonstrated by SDS-PAGE.

Abstract
Novel unilamellar and homogeneous titanate nanosheets were prepared by anchoring (3-aminopropyl)triethoxysilane (APTES) and chelating copper ions, also know by the short form Cu-APTES-TiNSs. The nanosheets were uniform two-dimensional lamellas/monolayers with a thickness of 1.9 nm, and they were further characterized by atomic force microscopy, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectra, X-ray diffraction, X-ray photoelectron spectroscopy, inductively coupled plasma mass spectrometry, and N2 adsorption-desorption. The copper-decorated titanate nanosheets possess a copper content of 4.28 ± 0.14% and exhibit a favorable selectivity to the adsorption of hemoglobin, with a considerable capacity of 5314.2 mg g-1. The adsorbed hemoglobin is easily collected with a recovery rate of 91.3% by using 0.5% w/v sodium dodecyl sulfate as an eluent. Circular dichroism spectra confirmed that virtually no conformational alteration is observed for hemoglobin. Cu-APTES-TiNSs are further applied for the selective adsorption of hemoglobin from the human whole blood.
