Abstract. Deciphering the complexity and heterogeneity of cancer, benefits from integration of proteomic level data into systems biology efforts.
Nasopharyngeal carcinoma (NPC) is a highly prevalent disease in Southeast Asia. The disease is typically diagnosed in the later stages, and chemotherapy
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.

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. iTRAQ enables relative and absolute quantitation of proteins and peptides by labelling samples with isotope encoded reporter ions.

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 recent years, proteomics analyses of serum, liver, kidney, and bone exposed to fluoride have been reported (Sun et al., 2018; Wei et al., 2016, 2018). Isobaric tag for relative and absolute quantization (iTRAQ) is a mature technique widely used in proteomics which can quantify proteins based on peptide labeling and allows the identification and quantification of peptides and proteins from various samples within broad dynamic ranges of protein abundance [ 6 A coupled iTRAQ/LC–MS/MS-based approach has been applied as a powerful sensitive proteomics tool for concurrently quantifying proteins in 4- or 8-plex samples during the discovery of disease biomarkers . However, to the best of our knowledge, there is no consequential study on the use of iTRAQ-based approaches in the identification of serum ITRAQ-based quantitative proteomics reveals the first proteome profiles of piglets infected with porcine circovirus type 3 HaijunJianga LiWeia DanWanga JingWanga ShanshanZhua RuipingSheb TianlongLiub JijingTianb RongQuana LeiHoua ZixuanLia JunChua JiyongZhouc YuxinGuoa YanyangXia Huiqi Songa FengYuana JueLiua In this study, we have explored the immune response of the hepatopancreas from L. vannamei fed with trans-vp28 gene Synechocystis sp. PCC6803 using iTRAQ-based proteomics. A total of 214 differentially expressed proteins (DEPs) were identified, of which 143 were up-regulated and 71 were down-regulated.

Today we will talk about quantitative proteomics and discuss about iTRAQ and TMT techniques. The quantitative proteomics aims to answer various questions including the identification of … 2020-12-19 Isobaric tags for relative and absolute quantitation (iTRAQ) is an isobaric labeling method used in quantitative proteomics by tandem mass spectrometry to determine the amount of proteins from different sources in a single experiment. iTRAQ (Multiplexed Isobaric Tagging Technology for Relative Quantitation) iTRAQ is a technique that utilizes a multiplexed isobaric chemical tagging reagent which allows multiplexing of two to eight protein samples and produces identical MS/MS sequencing ions for all eight versions of the same derivatized tryptic peptide.
