| Title |
d5_Acetate_H3K27ac |
| Sample type |
SRA |
| |
|
| Source name |
d5 1mM_Glucose + 5mM Acetate
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6
tissue: spleens and peripheral lymph nodes
cell type: CD8 T cells
days of glucose restriction: 1
genotype: OT-I
chip antibody: anti-H3K27ac (Diagenode, catalog number C15410196)
|
| Treatment protocol |
After 3 days, cells were switched to 1 mM glucose for 1 or 5 days (referred to as d5 and d9 respectively). 1 day before analysis, cells maintained in 1 mM glucose were treated with or without 5 mM sodium acetate (Sigma). Starting from day 2, and every day, cultured cells were harvested, washed, counted and plated at a concentration of 10^6 cells/ml in fresh medium with rhIL-2.
|
| Growth protocol |
OVA peptide-specific T cells were isolated from spleens and peripheral lymph nodes of OT-I transgenic mice and activated with the ovalbumin peptide SIINFEKL (OVA257-264, 100 ng/ml, New England Peptide). T cells were cultured in RPMI 1640, added with 10% heat-inactivated fetal bovine serum (Gibco, lot n. 1640960), glutamine (4 mM), penicillin/streptomycin (1%), β-mercaptoethanol (55 μM) and glucose (concentrations indicated in the text). Cells were grown at 37° C, in 5% CO2, atmospheric O2, in a humidified incubator. Briefly, cells were activated on day 0 with OVA257-264, with rhIL-2 (100 U/ml, Peprotech) in medium containing 25 mM glucose.

| Extraction protocol |
Fixed cell pellets (1% paraformaldehyde, 10 minutes, RT) were processed for multiplex RELACS (Arrigoni et al., 2018) and sequenced by the staff at the Deep-sequencing Facility at the Max-Planck-Institute for Immunobiology and Epigenetics.
