Rotaviruses infect cells by binding to specific cell surface molecules including gangliosides, heat shock protein cognate protein 70 (Hsc70), and some integrins. The characterization of cell surface receptors defining viral tropism is crucial for inhibiting entry into the normal cells or the cancer cells. In the present work, several tumor cell-adapted rotavirus isolates were tested for their interaction with some heat shock proteins (HSPs) present in the U-937 cells, derived from a human pleural effusion (histiocytic lymphoma monocyte). This interaction was examined by virus overlay protein-binding (VOPB), immunochemistry, immuno-dot blot assays, and flow cytometry. The results indicated that the rotavirus isolates studied were able to infect U937 cells by interacting with Hsp90, Hsp70, Hsp60, Hsp40, Hsc70, protein disulfide isomerase (PDI), and integrin β3, which are implicated in cellular proliferation, differentiation, and cancer development. Interestingly, these cellular proteins were found to be associated in lipid microdomains (rafts), facilitating in this way eventual sequential interactions of the rotavirus particles with the cell surface receptors. The rotavirus tropism for U937 cells through the use of these cell surface proteins made this rotavirus isolates an attractive target for the development of oncolytic strategies in the context of alternative and complementary treatment of cancer.
Hypertensive mediated heart disease is the consequence of anatomical and functional changes in cardiovascular system. The benefits on left ventricular (LV) diastolic impairment and remodeling of hypertension treatment are well established.

To evaluate LV structure, systolic and diastolic function of treated hypertensive patients on a medium to long term follow-up.

Prospectively observational cohort study. Hypertensive patients over 18 years, ultrasound evaluation of LV structure and diastolic and systolic function, follow-up at least once a year. Diastolic function assessed following recommendations of the American Society of Echocardiography and the European Association of Cardiovascular Imaging.

285 patients, mean follow up of 1731 ± 952 days. Sample mean age 56.3 ± 12.5 years, 166 patients (58.3%) were males. Baseline blood pressure 147.8 ± 19/86.8 ± 11 mm Hg, 5 years blood pressure 134.4 ± 15.7/79 ± 9 mm Hg (p < 0.005 SBP and p < 0.01 DBP). Baseline fixed dose combinations 115 patients (40.4%), follow-up 53.1% (p < 0.05). LV remodeling was detected in 88 patients (30.9%) vs. 30.1% at 5 years (p = NS). The frequency of an E/e' ratio > 14 was reduced from 38 patients (13.3%) to 3.6% (p < 0.001), e' septal velocity < 7 cm/sec or e' lateral velocity < 10 cm/sec was reduced from 38.6% (110 patients) to 19.3% (p < 0.001). Baseline normal diastolic function was detected in 85.6% (244 patients) and 94% at the end of the follow-up (p < 0.02).

In this observational cohort followed by a mean of 5 years, the main benefit of hypertension treatment was the prevention or regression of diastolic dysfunction.

Considering the complexity of the highly multiplexed spectral data, sophisticated workflows have been developed to obtain peptides quantification. Here we describe an open-source and easy-to-use workflow to obtain a quantitative matrix from multiple DIA runs. This workflow requires as prior information an "assay library," which contains the MS coordinates of peptides. It consists of OpenSWATH, pyProphet, and DIAlignR software. For the ease of installation and to isolate operating system-related dependency, docker-based containerization is utilized in this workflow.Data clustering facilitates the identification of biologically relevant molecular features in quantitative proteomics experiments with thousands of measurements over multiple conditions. It finds groups of proteins or peptides with similar quantitative behavior across multiple experimental conditions. This co-regulatory behavior suggests that the proteins of such a group share their functional behavior and thus often can be mapped to the same biological processes and molecular subnetworks.While usual clustering approaches dismiss the variance of the measured proteins, VSClust combines statistical testing with pattern recognition into a common algorithm. Here, we show how to use the VSClust web service on a large proteomics data set and present further tools to assess the quantitative behavior of protein complexes.Public databases featuring original, raw data from "Omics" experiments enable researchers to perform meta-analyses by combining either the raw data or the summarized results of several independent studies. In proteomics, high-throughput protein expression data is measured by diverse techniques such as mass spectrometry, 2-D gel electrophoresis or protein arrays yielding data of different scales. Therefore, direct data merging can be problematic, and combining the summarized data of the individual studies can be advantageous. A special form of meta-analysis is network meta-analysis, where studies with different settings of experimental groups can be combined. However, all studies must be linked by one experimental group that has to appear in each study. Usually that is the control group. Then, a study network is formed and indirect statistical inferences can also be made between study groups that appear not in each of the studies.In this chapter, we describe the working principle of and available software for network meta-analysis. The applicability to high-throughput protein expression data is demonstrated in an example from breast cancer research. We also describe the special challenges when applying this method.In mass spectrometry-based proteomics, relative quantitative approaches enable differential protein abundance analysis. Isobaric labeling strategies, such as tandem mass tags (TMT), provide simultaneous quantification of several samples (e.g., up to 16 using 16plex TMTpro) owing to its multiplexing capability. This technology improves sample throughput and thereby minimizes both measurement time and overall experimental variation. Phospho(enol)pyruvic acid monopotassium concentration However, TMT-based MS data processing and statistical analysis are probably the crucial parts of this pipeline to obtain reliable, plausible, and significantly quantified results. Here, we provide a step-by-step guide to the analysis and evaluation of TMT quantitative proteomics data.
