siTPR_tot_rep4 |
| Sample type |
SRA |
| |
|
| Source name |
WCE, siTPR cells, rep4
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: MCF-7 cell line
|
| Growth protocol |
MCF7 cells (ATCC) were grown in DMEM (Gibco) containing 10% fetal bovine serum and Penicillin-Streptomycin mixture (1%) at 37°C in a humidified incubator with 5% CO2. For export factor knockdown, cells were transfected with 10nM siRNA pool targeting indicated genes or with a control pool (Dharmacon) using Lipofectamin 3000 reagent (L3000001, Thermo Fisher). For double knockdowns, 5nM of each pool were used for a total mix of 10nM. Cells were collected for cytosolic and nuclear fractionation 72h post-transfection for all export factor depletion assays, except for siNXF1 and siALY+UAP56, where we collected the cells 48h post-transfection.

| Extracted molecule |
polyA RNA |
| Extraction protocol |
Cells were washed in cold PBS and detached from plates by 10mM EDTA, a fraction was transferred to a new tube and RNA was extracted with TRIREAGENT (MRC) to obtain WCE. Remaining cells were washed in cold PBS, resuspended in 180µl RLN buffer (50mM Tris•Cl pH8, 140mM NaCl, 1.5mM MgCl2, 10mM EDTA, 1mM DTT, 0.5% NP-40, 10U/ml RNAse inhibitor), and incubated on ice for 5 min. The extract was centrifuged for 5min at 300g in a cold centrifuge, the supernatant was transferred to a new tube and centrifuged again for 1min at 500g in a cold centrifuge. The supernatant (cytoplasmic fraction) was transferred to a new tube and RNA was extracted using TRIREAGENT. The nuclear pellet was washed once in 180µl RLN buffer, resuspended in 1ml of buffer S1 (250mM Sucrose, 10mM MgCl2, 10U/ml RNAse inhibitor), layered over 3ml of buffer S3 (880mM Sucrose, 0.5mM MgCl2, 10U/ml RNAse inhibitor), and centrifuged for 10min at 2800g in a cold centrifuge. The supernatant was removed and RNA was extracted from the nuclear pellet using TRIREAGENT.
