Proteomics of treatment of Arabidopsis thaliana with peptides

ABSTRACT: Plants were treated with a cPEP for luciferase (PEP Luc) or a scrambled version of this peptide (4 biological replicates each). Leaves were snap frozen in liquid nitrogen and grounded into powder. The powder was resuspended in tris 50 mM and 5% SDS, sonicated and centrifuged at 14,000 g for 10 min. A BCA protein assay was performed to estimate protein concentration in each sample. 50 ug of proteins were then loaded on a 12% Tris-glycine gel. Proteins were concentrated into one band and in gel digestion was performed as previously described (PMID: 25561571). 500 ng were then injected on a Thermofisher Exploris 480.

The current agriculture main challenge is to maintain food production while facing multiple threats such as increasing world population, temperature increase, lack of agrochemicals due to health issues and uprising of weeds resistant to herbicides. Developing novel, alternative, and safe methods is hence of paramount importance. Here, we show that complementary peptides (cPEPs) from any gene can be designed to target specifically plant coding genes. External application of synthetic peptides inc ...[more]

Project description:Glioblastoma stem cells (TS-543) were harvested and cross-linked with 1% formaldehyde for 10 mins at room temperature. The cells were lysed using SDS Lysis buffer for ChIP (1% SDS, 10 mM EDTA, 50 mM Tris-HCl pH 8). The lysate was then sonicated for 25 cycles at 30% amplitude (15 s ON and 45 s OFF). The sonicated samples were then diluted in ChIP dilution buffer (0.01% SDS, 1% Triton-X-100, 1.2 mM EDTA, 16.7 mM Tris–HCl pH 8, 167 mM NaCl) and used for the immunoprecipitation with H3K27ac (Abcam, Ab4729), H2AZ (Active motive, cat#39113) and H3K27ac (Abcam cat#ab8580). After an over-night incubation with antibody, the bound DNA was washed sequentially with low salt wash buffer (0.1% SDS, 1% Triton X 100, 2 mM EDTA, 20 mM Tris–HCl pH 8, 150 mM NaCl), high salt wash buffer (0.1% SDS, 1% Triton X-100, 2 mM EDTA, 20 mM Tris–HCl pH 8, 500 mM NaCl), LiCl wash buffer (0.25 M LiCl, 1% NP40, 1%deoxycholate, 1 mM EDTA, 10 mM Tris–HCl pH 8) and TE wash buffer (10 mM Tris–HCl pH 8, 1 mM EDTA) to remove non-specific sequences and eluted in the elution buffer (84 mg NaHCO3, 1 ml 10% SDS, 9 ml H2O). Then the samples were reverse cross-linked using NaCl at 65°C overnight. The eluted DNA was purified and used for library preparation. Library preparation was performed as previously described as described in Bowman et al. BMC Genomics 2013. Briefly, end repair with NEBNext End Repair enzyme (NEB, E6050) and clean-up with 2.4x volume AMPure XP beads (Beckman Coulter, A63880). A-tailing with Klenow Fragment (NEB, M0212) and purified with 2.4x volume AMPure XP beads. Adapter ligation reactions contained annealed universal adapter and T4 rapid ligase (NEB, B0202) and clean-up with 1.8x volume AMPure XP beads. Chromatin was amplified using KAPA Real-time Library Amplification Kit (KAPABIOSYSTEMS, KK2701) with universal primer and barcoded primer. Amplified chromatin was purified with QIAquick Gel Extraction Kit (Qiagen) and sequenced paired-end with Illumina NextSeq 500.

Project description:U2OS osteosarcoma cells were cultured in Dulbecco's modified Eagle's medium (DMEM, Gibco) and Raji B-cells in RPMI 1640 medium (Gibco) supplemented with 10% fetal calf serum (FCS, Bio&Sell), 2 mM L-glutamine (Gibco), 100 U/mL penicillin (Gibco), and 100 µg/mL streptomycin (Gibco) at 37°C at 8% or 5% CO2, respectively. Chromatin immunoprecipitation for ChIP-seq: Cells were crosslinked using a formaldehyde containing solution (10mM NaCl, 0,1mM EDTA pH 8, 0,05mM EGTA pH 8, 5mM HEPES pH 7.8 and 1% formaldehyde) for 10 minutes at 20°C, the reaction was quenched by the addition of glycin to a final concentration of 250uM for 5 minutes. Crosslinked cells were collected and washed twice with PBS before snap freezing in liquid nitrogen and storage at -80°C until subsequent use. Prior to sonication, the crosslinked cells were resuspended in lysis buffer (50mM Hepes pH 7.5, 140mM NaCl, 1mM EDTA pH 8, 10% glycerol, 0.75% NP-40, 0.25% Triton X-100, 1X protease inhibitor cocktail) at 4°C for 20 minutes. Nuclei were collected by centrifugation and washed in a second buffer (200mM NaCl, 1mM EDTA pH 8, 0.5mM EGTA pH 8, 10mM Tris pH 8, 1X protease inhibitor cocktail) for 10 minutes at 4°C then collected by centrifugation and resuspended in the shearing buffer (1mM EDTA pH 8, 0.5mM EGTA pH 8, 10mM Tris pH 8, 100mM NaCl, 0.1% Na-Deoxycholate, 0.5% N-lauroylsarcosine, 1X protease inhibitor cocktail). Sonication was carried out in a Bioruptor Pico ultrasounds water bath (Diagenode B01060001) for 30 cycles of 30 sec ON and 30 sec OFF pulses in 4°C water. Sonicated extracts were centrifuged at high speed in the presence of 0,1% of Triton X-100 and snap frozen in liquid nitrogen then stored at -80°C until subsequent use. Prior to ChIP, the ZNF768 mAb was coupled to protein-G coated magnetic beads (Dynabeads, life technologies) by incubation in 0,5% BSA PBS overnight at 4°C. Pre-coated beads were then washed and incubated with the sonicated chromatin extracts, the ChIP was carried out overnight at 4°C on a rotating wheel. The equivalent of 10 × 107 cells sonicated extract was used for each ZNF ChIP experiment for both cell lines. After incubation, the beads were washed 7 times with Wash buffer (50mM Hepes pH 7.6, 500mM LiCl, 1mM EDTA pH 8, 1% NP-40, 0.7% Na-Deoxycholate, 1X protease inhibitor cocktail) followed by one wash with TE-NaCl buffer (10mM Tris pH 8 and 1mM EDTA pH 8, 50mM NaCl). Immunoprecipitated chromatine was eluted by two sequential incubations with 100µl Elution buffer (50mM Tris pH 8, 10mM EDTA pH 8, 1% SDS) at 65°C for 15 minutes. The two eluates were pooled and incubated at 65°C for 12 hours to reverse-crosslink the chromatin followed by treatment with RNase A (0.2µg/mL) at 37°C for two hours and Proteinase K (0.2µg/mL) at 55°C for two hours. The DNA was isolated by phenol:chloroform: isoamylalcohol (25:24:1 pH 8) extranction followed by Qiaquick PCR Purification (Qiagen, Germany) and quantified with Qubit DS DNA HS Assay (ThermoFisher Scientific, USA). At least 1ng of ChIP DNA was used to prepare sequencing library with Illumina ChIP Sample Library Prep Kit (Illumina, USA) with a few optimizations to the protocol. The ChIP DNA was size selected using Ampure beads (Life technologies) to enrich for fragments < 400Bp prior to end-repair, 3’end adenylation and adapter ligation. Library fragments were then directly amplified by 10 cycles of PCR.
