Aging has been associated with a progressive decline of proteostasis, but how this process affects proteome composition remains largely unexplored. Here, we profiled more than 5,000 proteins along the lifespan of the nematode C. elegans. We find that one-third of proteins change in abundance at least 2-fold during aging, resulting in a severe proteome imbalance. These changes are reduced in the long-lived daf-2 mutant but are enhanced in the short-lived daf-16 mutant. While ribosomal proteins de ...[more]

Unstressed HeLa cells and ELAVL1/HuR knock down conditions: polyA RNA-Seq, small RNA-Seq, and PAR-CLIP

Project description:Post-transcriptional gene regulation relies on hundreds of RNA binding proteins (RBPs) but the function of most RBPs is unknown. The human RBP HuR/ELAVL1 is a conserved mRNA stability regulator. We used PAR-CLIP, a method based on RNA-protein crosslinking, to identify transcriptome wide ~26,000 HuR binding sites. These sites were on average highly conserved, enriched for HuR binding motifs and mainly located in 3' untranslated regions. Surprisingly, many sites were intronic, implicating HuR in splicing. Upon HuR knock down, mRNA levels and protein synthesis of thousands of target genes was down regulated, validating functionality. HuR and miRNA binding sites tended to reside nearby but generally did not overlap. Additionally, HuR knock down triggered strong and specific up regulation of miR-7. In summary, we identified thousands of direct and functional HuR targets, found a human miRNA controlled by HuR, and propose a role for HuR in splicing. PolyA mRNA was extracted from anti HuR siRNA treated and mock transfected HeLa cells to identify changes in mRNA expression and splicing. 2x100 paired end sequencing was performed according to the protocol on the Illumina HiSeq. PARCLIP was performed as in Hafner et. Al 2010 but with an antibody against endogenous HuR (3A2, Santa Cruz, sc-5261) in unstressed HeLa cells. We used, independently, 4-thiouridine (4SU) and 6-thioguanosine (6SG) to assess a possible nucleotide bias. As our proteomics measurements required labeling of cells in a special medium we also performed PAR-CLIP on cells grown in SILAC medium. Altogether we performed three PAR-CLIP experiments: 4SU labeling in standard DMEM medium, 4SU labeling in SILAC medium (as a replicate) and 6SG labeling in SILAC medium. Small RNA was extracted from anti HuR siRNA treated and mock transfected HeLa cells to identify changes in mRNA expression. Sequencing was performed on Illumina GAII using the standard sRNA 36cycle protocol.

Quantitative phosphoproteomic analysis reveals reciprocal activation of receptor tyrosine kinases between cancer epithelial cells and their interacting stromal fibroblast cells

Project description:Communication and interaction between carcinoma associated fibroblast (CAF) cells and tumor epithelium cells plays a critical role in cancer initiation and progression. However, a mechanistic understanding of how CAFs communicate with tumor cells to promote their proliferation and invasion is far from complete. In this study, we employed a SILAC labeling based co-culture system coupled with mass spectrometry analysis to identify and quantify the early phospho-signaling transductions induced by the crosstalk between CAFs and tumor cells. We performed three-state SILAC labeling for MDA-MB-231 and 82T. 9 million light labeled 82-L cells were co-cultured with medium labeled MDA-MB-231-M cells for 30 minutes. 9 million heavy labeled 82T-H cells were individually cultured in heavy SILAC media with for 30 minutes. Both individually cultured and co-cultured cells were quickly harvested with 9 M urea lysis buffer and mixed together. Mixed lysates were sonicated, reduced, alkylated and digested by trypsin. Tryptic peptides were desalted using SepPak C18 cartridge and followed by phosphotyrosine peptide enrichment using immunoaffinity purification with pY100 antibody. The enriched phosphopeptides were analyzed using a reverse-phase liquid chromatography system interfaced with an LTQ-Orbitrap Velos mass spectrometer. The Proteome Discoverer (v2.0; Thermo Fisher Scientific) suite was used for quantitation and database searches. The tandem mass spectrometry data were searched using SEQUEST search algorithm against a Human RefSeq database supplemented with frequently observed contaminants. The probability of phosphorylation sites was determined from the PhosphoRS algorithm.

Dynamic profiling of the protein life cycle in response to pathogens (protein)

Project description:Protein expression is regulated by production and degradation of mRNAs and proteins, but their specific relationships remain unknown. We combine measurements of protein production and degradation and mRNA dynamics to build a quantitative genomic model of the differential regulation of gene expression in LPS stimulated mouse dendritic cells. Changes in mRNA abundance play a dominant role in determining most dynamic fold changes in protein levels. Conversely, the preexisting proteome of proteins performing basic cellular functions is remodeled primarily through changes in protein production or degradation, accounting for over half of the absolute change in protein molecules in the cell. Thus, the proteome is regulated by transcriptional induction of novel cellular functions and remodeling of preexisting functions through the protein life cycle. Mouse primary dendritic cells were treated with LPS or mock stimulus and profiled over a 12-hour time course. Cells were grown in M-labeled SILAC media, which was replaced with H-labeled SILAC media at time 0. Aliquots were taken at 0, 0.5, 1, 2, 3, 4, 5, 6, 9, and 12 hours post-stimulation and added to equal volumes of a master mix of unlabeled (L) cells for the purpose of normalization. RNA-Seq was performed at 0, 1, 2, 4, 6, 9, and 12 hours post-stimulation.

Evaluation of computational tools using serial mixtures of human plasma and vegetable juice (part-I)

Project description:Mass spectrometry-based metabolomics is developed rapidly in the past few decades. There are few major vendors for LC-MS platform instruments, for example, Thermo ScientificTM LTQ Orbitrap Velos and Agilent 6510 Q-TOF mass spectrometer were used for metabolomics research. The data acquired cross different platform are rarely compared other than the comparison of the instrument itself on resolution, mass accuracy, sensitivity, dynamic range, scan speed etc., which is largely due to the foundation and principle of the instrument design. Other than this, there are many choice for data preprocessing, i.e., the data acquired from the same platform may have been processed with different feature extraction software tools. The discrepancy for the feature detections with different software will lead to the variation of the down-stream statistics analysis and metabolomics pathway interpretation. In addition, the impact of the LC-MS platform and data preprocessing software tools on the quantitative capabilities is also an interesting topic. In this research, XCMS, mzMine 2.37 and apLCMS are three tools used for the feature extraction of data acquired with Thermo ScientificTM LTQ Orbitrap Velos and Agilent 6510 Q-TOF LC-MS platform by serial dilution experiment. The quantification capability is estimated at the same time based on the linearity, accuracy, and precision

Phosphoproteomic analysis of breast epithelial cells with isogenic knockin of PIK3CA mutations

Project description:The PIK3CA gene is frequently mutated in human cancers. To study the signaling mechanisms responsible for cell growth and invasion phenotypes induced by mutant PIK3CA molecules, we carried out a SILAC-based quantitative phosphoproteomic analysis of MCF10A, a spontaneously immortalized normal mammary epithelial cell line, and two MCF10A knockin cell lines containing different activating mutations of the PIK3CA gene. MCF10A and PIK3CA mutation knock in cells were propagated in DMEM/F12 SILAC media deficient in both L-lysine and L-arginine and supplemented with light lysine (K) and arginine (R) for light, 2H4-K and 13C6-R for medium state and 13C615N2-K and 13C615N4-R for heavy state labeling. Cell lysates were prepared in urea lysis buffer containing 20 mM HEPES pH 8.0, 9 M urea, 1 mM sodium orthovanadate, 2.5 mM sodium pyrophosphate, 1 mM ß-glycerophosphate and 5mM sodium fluoride. The lysates were reduced, alkylated and digested by trypsin. Tryptic peptides were desalted by C18 reverse phase column and followed by strong cation exchange (SCX) fractionation. Fractionated peptides were subjected to TiO2-based phosphopeptide enrichment. LC-MS/MS analysis of enriched phosphopeptides was carried out using a reverse-phase liquid chromatography system interfaced with an LTQ-Orbitrap Velos mass spectrometer. Proteome Discoverer (v 1.3) suite was used for quantitation and database searches. The tandem mass spectrometry data were searched using Mascot (2.2.0) and SEQUEST search algorithms against a Human RefSeq database supplemented with frequently observed contaminants.
