2021-01-01 · Proteomics offers an effective tool to monitor the molecular pathways that govern cellular metabolism. Over the last few years, the non-gel-based isobaric tags for relative and absolute quantification (iTRAQ) proteomics method has been widely applied for proteomics analyses because of its high throughput, strong sensitivity, and outstanding accuracy ( Xia et al., 2017 ; Li et al., 2016 ). In the present study, we utilized iTRAQ-based quantitative proteomics to analyze the protein alterations in Streptococcus pneumoniae in response to SNH treatment. Numerous proteins related to the production of reactive oxygen species (ROS) were found to be up-regulated by SNH, suggesting that ROS pathways may be involved as analyzed via bioinformatics. The use of proteomics to identify key proteins associated with abortion can provide insight into the mechanisms of ERSA. In this study, we found 78 differentially expressed proteins using iTRAQ, and bioinformatics analysis demonstrated that these proteins were implicated in several biological processes and molecular functions. iTRAQ-based Proteomics Analysis iTRAQ, using isobaric reagents to label peptides, is ideally suited for comparing normal, diseased, and drug-treated samples, time course studies, biological replicates and provides relative quantitation information.
2020-02-10 · To date, proteomic methods are widely considered important tools for determining host cellular responses to virus infection and provide valuable information to better understand the cellular mechanisms underlying viral pathogenesis. iTRAQ combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis has become a powerful quantitative proteomic approach due to its remarkable advantages over traditional proteomic methods, such as its high-throughput setup, high

For more details on NPTEL visit http://nptel.iit Speaking of iTRAQ (Isobaric Tag for Relative and Absolute Quantitation) and TMT (Tandem Mass Tag), many of us may think that they are two different quantitative proteomics techniques, but in fact… 2020-07-21 · In conclusion, iTRAQ-based proteomics analysis identified 79 proteins that interact with FASN. Four proteins (FSCN1, SIPA1, SPTBN1 or CD59) closely associated with tumor metastasis interacted with FASN and exhibited decreased expression in response to FASN silencing.
These techniques use multiplexed isobaric mass tags to label peptide digest mixtures.

Analysis of differentially expressed proteins involved in autoimmune cirrhosis and normal serum by iTRAQ proteomics. Proteomics Clin Appl. 2019;13(3):e1700153. Isobaric Tag for Relative Absolute Quantitation (iTRAQ) and Tandem Mass Tags (TMT) are two similar quantitative proteomic techniques developed by AB SCIEX and Thermo Fisher, respectively. The most distinctive advantage of these two techniques is that they can label up to 10 different samples and compare the relative proteomic change through LC-MS/MS analysis. Comprehensive comparisons of quantitative proteomics techniques are rare in the literature, yet they are crucially important for optimal selection of approaches and methodologies that are ideal for a given proteomics initiative.
Zhang K, Pan X, Zheng J, et al. Comparative tissue proteomics analysis of thoracic aortic dissection with hypertension using the iTRAQ technique. A quantitative proteomics approach using an isobaric chemical labeling reagent, iTRAQ, to identify the proteome regulated by SLs in Arabidopsis seedlings is presented. It was found that SLs regulate the expression of about three dozen proteins that have not been previously assigned to SL pathways. iTRAQ iTRAQ technology coupled with 1D or 2D LC-MS/MS for multiplexing 4-8 samples simultaneously in a single experiment is available.
