Abstract
This work reports highly selective phosphopeptide enrichment using amorphous TiO2 nanotubes (TiO2NTs) and the same material decorated with superparamagnetic Fe3O4 nanoparticles (TiO2NTs@Fe3O4NPs). TiO2NTs and TiO2NTs@Fe3O4NPs materials were applied for phosphopeptide enrichment both from a simple peptide mixture (tryptic digest of bovine serum albumin and α-casein) and from a complex peptide mixture (tryptic digest of Jurkat T cell lysate). The obtained enrichment efficiency and selectivity for phosphopeptides of TiO2NTs and TiO2NTs@Fe3O4NPs were increased to 28.7 and 25.3%, respectively, as compared to those of the well-established TiO2 microspheres. The enrichment protocol was extended for a second elution step facilitating the identification of additional phosphopeptides. It further turned out that both types of amorphous TiO2 nanotubes provide qualitatively new physicochemical features that are clearly advantageous for highly selective phosphopeptide enrichment. This has been confirmed experimentally resulting in substantial reduction of non-phosphorylated peptides in the enriched samples. In addition, TiO2NTs@Fe3O4NPs combine high selectivity and ease of handling due to the superparamagnetic character of the material. The presented materials and performances are further promising for applications toward a whole range of other types of biomolecules to be treated in a similar fashion.

Abstract
Metal oxide affinity chromatography (MOAC) is one of the most commonly used techniques for selective isolation phosphoproteins and phosphopeptides. This technique is capable of capturing the phosphorylated biomolecules through the affinity of the phosphoryl group for metal oxides/hydroxides. Fly-ash (FA), a by-product of coal-combustion power plants, is primarily composed of oxides of silicon and metals, among which iron and titanium. A number of studies have demonstrated the potential of these metal oxides for phosphoprotein and phosphopeptide enrichment. FA is annually produced over hundred million tons worldwide and generally considered as hazardous waste. It is thus of great importance to enhance its utilization. Here we present the first demonstration of the utility of FA as a low-cost MOAC material for the enrichment of phosphoproteins. With an FA-microcolumn, phosphoproteins can be successfully sequestered from other proteins. FA-microcolumns are shown to be simple, cheap and selective devices for phosphoprotein enrichment from a small volume of mixtures.

Radio-sensitizing effects of VE-821 and beyond: Distinct phosphoproteomic and metabolomic changes after ATR inhibition in irradiated MOLT-4 cells. PLoS One 2018; 13:e0199349.

Abstract
Current anti-cancer strategy takes advantage of tumour specific abnormalities in DNA damage response to radio- or chemo-therapy. Inhibition of the ATR/Chk1 pathway has been shown to be synthetically lethal in cells with high levels of oncogene-induced replication stress and in p53- or ATM- deficient cells. In the presented study, we aimed to elucidate molecular mechanisms underlying radiosensitization of T-lymphocyte leukemic MOLT-4 cells by VE-821, a higly potent and specific inhibitor of ATR. We combined multiple approaches: cell biology techniques to reveal the inhibitor-induced phenotypes, and quantitative proteomics, phosphoproteomics, and metabolomics to comprehensively describe drug-induced changes in irradiated cells. VE-821 radiosensitized MOLT-4 cells, and furthermore 10 μM VE-821 significantly affected proliferation of sham-irradiated MOLT-4 cells. We detected 623 differentially regulated phosphorylation sites. We revealed changes not only in DDR-related pathways and kinases, but also in pathways and kinases involved in maintaining cellular metabolism. Notably, we found downregulation of mTOR, the main regulator of cellular metabolism, which was most likely caused by an off-target effect of the inhibitor, and we propose that mTOR inhibition could be one of the factors contributing to the phenotype observed after treating MOLT-4 cells with 10 μM VE-821. In the metabolomic analysis, 206 intermediary metabolites were detected. The data indicated that VE-821 potentiated metabolic disruption induced by irradiation and affected the response to irradiation-induced oxidative stress. Upon irradiation, recovery of damaged deoxynucleotides might be affected by VE-821, hampering DNA repair by their deficiency. Taken together, this is the first study describing a complex scenario of cellular events that might be ATR-dependent or triggered by ATR inhibition in irradiated MOLT-4 cells. Data are available via ProteomeXchange with identifier PXD008925.

Abstract
Phosphorylation is one of the most important post-translational modifications in proteins. Their essential roles in the regulation of cellular processes and alteration of protein-protein interaction networks have been actively studied. However, phosphorylated proteins are present at low abundance in cells, and ionization of the modified peptides is often suppressed by the more abundant species in mass spectrometry. Effective enrichment techniques are needed to remove the unmodified peptides and concentrate the phosphorylated ones before their identification and quantification. Herein, we prepared ZrO2 nanofibers by electrospinning, a straightforward and easy fabrication technique, and applied them to enrich phosphorylated peptides and proteins. The fibers showed good size homogeneity and porosity and could specifically bind to the phosphorylated peptides and proteins, allowing their separation from the unmodified analogues when present in either simple protein digests or highly complex cell lysates. The enrichment performance was superior to that of the commercially available nanoparticles. Moreover, modifying the solution pH could lead to selective adsorption of proteins with different pI values, suggesting the fibers' potential applicability in charge-based protein fractionation. Our results support that the electrospun ZrO2 nanofibers can serve as a versatile tool for protein analysis with great ease in preparation and handling.

Radiosensitization of human leukemic HL-60 cells by ATR kinase inhibitor (VE-821): phosphoproteomic analysis. Int J Mol Sci 2014; 15:12007-26. [PMID: 25003641 PMCID: PMC4139827 DOI: 10.3390/ijms150712007] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2014] [Revised: 04/18/2014] [Accepted: 04/28/2014] [Indexed: 01/18/2023] Open
Abstract
DNA damaging agents such as ionizing radiation or chemotherapy are frequently used in oncology. DNA damage response (DDR)-triggered by radiation-induced double strand breaks-is orchestrated mainly by three Phosphatidylinositol 3-kinase-related kinases (PIKKs): Ataxia teleangiectasia mutated (ATM), DNA-dependent protein kinase (DNA-PK) and ATM and Rad3-related kinase (ATR). Their activation promotes cell-cycle arrest and facilitates DNA damage repair, resulting in radioresistance. Recently developed specific ATR inhibitor, VE-821 (3-amino-6-(4-(methylsulfonyl)phenyl)-N-phenylpyrazine-2-carboxamide), has been reported to have a significant radio- and chemo-sensitizing effect delimited to cancer cells (largely p53-deficient) without affecting normal cells. In this study, we employed SILAC-based quantitative phosphoproteomics to describe the mechanism of the radiosensitizing effect of VE-821 in human promyelocytic leukemic cells HL-60 (p53-negative). Hydrophilic interaction liquid chromatography (HILIC)-prefractionation with TiO2-enrichment and nano-liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis revealed 9834 phosphorylation sites. Proteins with differentially up-/down-regulated phosphorylation were mostly localized in the nucleus and were involved in cellular processes such as DDR, all phases of the cell cycle, and cell division. Moreover, sequence motif analysis revealed significant changes in the activities of kinases involved in these processes. Taken together, our data indicates that ATR kinase has multiple roles in response to DNA damage throughout the cell cycle and that its inhibitor VE-821 is a potent radiosensitizing agent for p53-negative HL-60 cells.
