A code of mono-phosphorylation modulates the function of RB

ABSTRACT: The data were acquired by performing multiplexed proteomics with TMT10-plex reagents using both and Orbitrap Fusion and an Orbitrap Lumos mass spectrometer and applying an SPS-supported LC-MS2/MS3 method. Samples were anti-FLAG immunoprecipitates of RB phospho-isoforms from human RPE1 cells.

Project description:Mass spectrometry-based proteomics was applied to unravel Erk signaling in mouse embryonic stem cells (ESCs). A previously described engineered ESCs system for Erk induction via a drug-inducible cRAF-ErT2 fusion (Hamilton, W. B. & Brickman, J. M., Cell Rep 2014) was used in two different setups measuring the phosphoproteome in an 11-plex tandem mass tag (TMT)-based approach as described below. Fgf4 stimulation and MEK inhibition: ESCs were stimulated with Fgf4 (40 nM, recombinant, mouse, 5 minutes) following pretreatment (30 minutes) with either DMSO (1:10000) or MEK inhibition (MEKi: 1 microM PD0325901): The experimental treatment conditions and TMT11-plex labeling are specified below: 126: DMSO, unstimulated control replicate 1 127N: DMSO, unstimulated control replicate 2 127C: DMSO, unstimulated control replicate 3 128N: DMSO + Fgf4 replicate 1 128C: DMSO + Fgf4 replicate 2 129N: DMSO + Fgf4 replicate 3 129C: MEKi + Fgf4 replicate 1 130N: MEKi + Fgf4 replicate 2 130C: MEKi + Fgf4 replicate 3 131N: MEKi replicate 1 131C: MEKi replicate 2 Analog sensitive Erk2 setup: In the ESC system the ERK2-/- ESCs (Hamilton et al., PloS ONE, 2013) were engineered to stably express an inducible cRAF-ErT2 fusion protein expressed from the same transgene as a FLAG-tagged analogue sensitive Erk2Q103A. Erk1 was subsequently removed by CRISPR-Cas9 mutagenesis using sgRNAs flanking exon 2. Cells were pre-treated for 30 minutes with either the ATP-mimetic compound 1-NM-PP1 (2 microM) (Endo et al., Biochem Biophys Res Commun 2006), the Mek1 inhibitor PD0325901 (1 microM), or DMSO (0.01%), followed by induction or not of the cRAF-ErT2 fusion by (Z)-4-Hydroxytamoxifen (4OHT) (250 nM) for 2 hours as indicated. The experimental treatment conditions and TMT11-plex labeling are specified below: 126: DMSO pretreatment, non-induced control, replicate 1 127N: DMSO pretreatment, non-induced control, replicate 2 127C: DMSO pretreatment, non-induced control, replicate 3 128N: DMSO pretreatment, 4OHT-induction, replicate 1 128C: DMSO pretreatment, 4OHT-induction, replicate 2 129N: DMSO pretreatment, 4OHT-induction, replicate 3 129C: PP1 pretreatment, 4OHT-induction, replicate 1 130N: PP1 pretreatment, 4OHT-induction, replicate 2 130C: PP1 pretreatment, 4OHT-induction, replicate 3 131N: MEKi pretreatment, 4OHT-induction, replicate 1 131C: MEKi pretreatment, 4OHT-induction, replicate 2

Project description:The small molecule YC-1 was identified as identified as a selectively active agent against subsets of the two major live cancer subtypes, intrahepatic cholangiocarcinoma and hepatocellular carcinoma. Response to YC-1 is dependent on the expression of the sulfotransferase SULT1A1, which activates YC-1 through sulfonation. The contributions of mass spectrometry to the study were: (i) identifying SULT1A1 as the key player in YC-1 response through observing the protein in a cell line with acquired resistance to the small molecule treatment, (ii) corroborating the role of SULT1A1 in the YC-1 activity by correlating protein expression profiles and drug responses across 37 biliary cancer cell lines, (iii) showing that SULT1A1 expression was associated with IDH mutations, FGFR2 fusion, and BAP1 loss in vivo studying patient-derived xenograft (PDX) models, and (iv) identifying protein targets in a protein enrichment experiment with an immobilized drug. (i) and (ii): Cell line samples from datasets (i) and (ii) were analyzed together in a set of 12 TMT sets (ShiBardeesy_CellLines_TMT1 to TMT12) using TMT11-barcoding. The samples were analyzed on an Orbitrap Lumos mass spectrometer using the SPS-MS3 method. Prior to analysis, samples were fractionated offline using high pH reversed chromatography (12 fractions per TMT set). Across all TMT sets, channel 131c was used as the bridge channel (pooled digests of all samples). Samples were labeled as follows (rep = replicate: (i) Cell lines samples with acquired resistance to YC-1 treatment: ShiBardeesy_CellLines_TMT1: RBE_rep_1 (126), RBE YC1 Resistant 6_rep_1 (129c).
