Mus musculus |
Characteristics |
cell line: NIH-3T3 cell type: Fibroblasts chip antibody: Menin
|
Growth protocol |
Cells were maintained in Dulbecco's Modified Eagle Medium (DMEM, Gibco) supplemented with 10% fetal calf serum (ATCC) and Penicillin-Streptomycin. Cells were harvested four days after being treated with Menin-MLL inhibitor in this same media composition.

Extraction protocol |
Cross-linking ChIP in mouse NIH-3T3 cells was performed with 10-20x107 cells per immunoprecipitation. After drug (or vehicle) treatment, cells were collected, washed once with ice-cold PBS, and flash-frozen. Cells were resuspended in ice-cold PBS and cross-linked using 1% paraformaldehyde (PFA) (Electron Microscopy Sciences) for 5 minutes at room temperature with gentle rotation. Unreacted PFA was quenched with glycine (final concentration 125mM) for 5 minutes at room temperature with gentle rotation. Cells were washed once with ice-cold PBS and pelleted by centrifugation (800g for 5 minutes). To obtain a soluble chromatin extract, cells were resuspended in 1mL of LB1 (50mM HEPES pH 7.5, 140mM NaCl, 1mM EDTA, 10% glycerol, 0.5% NP-40, 0.25% Triton X-100, 1X complete protease inhibitor cocktail) and incubated at 4°C for 10 minutes while rotating. Samples were centrifuged (1400g for 5 minutes), resuspended in 1mL of LB2 (10mM Tris-HCl pH 8.0, 200mM NaCl, 1mM EDTA, 0.5mM EGTA, 1X complete protease inhibitor cocktail), and incubated at 4°C for 10 minutes while rotating. Finally, samples were centrifuged (1400g for 5 minutes) and resuspended in 1mL of LB3 (10mM Tris-HCl pH 8.0, 100mM NaCl, 1mM EDTA, 0.5mM EGTA, 0.1% sodium deoxycholate, 0.5% N- Lauroylsarcosine, 1X complete protease inhibitor cocktail). Samples were homogenized by passing 7-8 times through a 28-gauge needle and Triton X-100 was added to a final concentration of 1%. Chromatin extracts were sonicated for 14 minutes using a Covaris E220 focused ultrasonicator. Lysates were centrifuged at maximum speed for 10 minutes at 4°C and 5% of supernatant was saved as input DNA. Beads were prepared by incubating in 0.5% BSA in PBS and antibodies overnight (100μL of Dynabeads Protein A or Protein G (Invitrogen) plus 20μL of antibody). NEBNext Ultra II DNA

Data processing |
ChIP-seq reads are aligned using Rsubread’s align method and predicted fragment lengths calculated by the ChIPQC R Bioconductor package. Normalized, fragment extended signal bigWigs are created using the rtracklayer R Bioconductor package. Peak calls are made in MACS2 software.
