Urine metabonomics reveals early biomarkers in diabetic cognitive dysfunction

10.1021/acs.jproteome.7b00168

2017-07-19

Recently, increasing attention has been paid to diabetic encephalopathy which is one of frequent diabetic complications and affects nearly 30% diabetics. Since cognitive dysfunction from diabetic encephalopathy might develop irreversible dementia, early diagn...

First time view on human metabolome changes after a single intake of 3,4 methylenedioxymethamphetamine (MDMA) in healthy placebo-controlled subjects

10.1021/acs.jproteome.7b00294

2017-07-19

3,4-methylenedioxymethamphetamine (MDMA; ‘ecstasy’) is widely consumed recreationally. Currently little is known about its effects on the human metabolome. Mapping biochemical changes after drug exposure can complement traditional approaches by revealing pote...

Global Phosphoproteomic Analysis of Insulin/Akt/mTORC1/S6K Signaling in Rat Hepatocytes

10.1021/acs.jproteome.7b00140

2017-07-19

Insulin resistance is a hallmark of type 2 diabetes. Although multiple genetic and physiological factors interact to cause insulin resistance, deregulated signaling by phosphorylation is a common underlying mechanism. In particular, the specific phosphorylati...

Characterization of the Extracellular Matrix of Normal and Diseased Tissues Using Proteomics

10.1021/acs.jproteome.7b00191

2017-07-19

The extracellular matrix (ECM) is a complex meshwork of insoluble fibrillar proteins and signaling factors interacting together to provide architectural and instructional cues to the surrounding cells. Alterations in ECM organization or composition and excess...

Targeted Feature Detection for Data-Dependent Shotgun Proteomics

10.1021/acs.jproteome.7b00248

2017-07-19

Label-free quantification of shotgun LC–MS/MS data is the prevailing approach in quantitative proteomics but remains computationally nontrivial. The central data analysis step is the detection of peptide-specific signal patterns, called features. Peptide quan...

Proteomics Profiling of Exosomes from Primary Mouse Osteoblasts under Proliferation versus Mineralization Conditions and Characterization of Their Uptake into Prostate Cancer Cells

10.1021/acs.jproteome.6b00981

2017-07-18

Osteoblasts communicate both with normal cells in the bone marrow and with tumor cells that metastasized to bone. Here we show that osteoblasts release exosomes, we termed osteosomes, which may be a novel mechanism by which osteoblasts communicate with cells ...

A Human Tyrosine Phosphatase Interactome Mapped by Proteomic Profiling

10.1021/acs.jproteome.7b00065

2017-07-18

Tyrosine phosphatases play a critical role in many cellular processes and pathogenesis, yet comprehensive analysis of their functional interacting proteins in the cell is limited. By utilizing a proteomic approach, here we present an interaction network of 81...

Selective Affinity Enrichment of Nitrotyrosine-Containing Peptides for Quantitative Analysis in Complex Samples

10.1021/acs.jproteome.7b00275

2017-07-17

Protein tyrosine nitration by oxidative and nitrate stress is important in the pathogenesis of many inflammatory or aging-related diseases. Mass spectrometry analysis of protein nitrotyrosine is very challenging because the non-nitrated peptides suppress the ...

Comprehensive Proteomic Analysis of PGC7-Interacting Proteins

10.1021/acs.jproteome.6b00883

2017-07-16

Primordial germ cell 7 (PGC7), a maternal factor essential for early development, plays a critical role in the regulation of DNA methylation, transcriptional repression, chromatin condensation, and cell division and the maintenance of cell pluripotentiality. ...

Quantitative Proteomics Reveals Potential Crosstalk between a Small RNA CoaR and a Two-Component Regulator Slr1037 in Synechocystis sp. PCC6803

10.1021/acs.jproteome.7b00243

2017-07-14

Bacterial small RNAs (sRNAs) and two-component systems (TCSs) were two vital regulatory mechanisms employed by microorganisms to respond to environmental changes and stresses. As a promising “autotrophic cell factory”, photosynthetic cyanobacteria have attrac...
