| Title |
MCF7_MR74_input_rep1 |
| Sample type |
SRA |
| |
|
| Source name |
MCF7
|
| Organism |
Homo sapiens |
| Characteristics |
sample type: human cell line, plasmid with mouse sequence
cell line: MCF7
cell type: human breast cancer
treatment: Plasmid transfection with an insert described in the 'description'. Insert sequences are in TableS1.xlsx.
|
| Treatment protocol |
Transfections were done with JetPrime (Polyplus) reagent, according to the supplier’s instructions. Typically, the cells were seeded in 6-cm dishes (Corning) and on the next day transfected with 1-2µg of plasmids. The cells were harvested after additional 24 hours by scraping and subjected to RNA extraction.
|
| Growth protocol |
MCF7 cells (ATCC) were maintained in DMEM (GIBCO) supplemented with 10% FBS and 1% Penicillin and Streptomycin.
|
| Extracted molecule |
polyA RNA |
| Extraction protocol |
RNA was extracted with BIO TRI RNA reagent (Bio-lab)
RNA was poly-A selected with oligo dT-beads (Dynabeads® mRNA DIRECT™ Kit life tech) and subjected to m6Aseq2 according to Dierks et al, 2021 Nature Methods.

| Description |
MCF7 cells transfected with MR74 with intron, m6A input sample, replicate 1, part of experiment 3
|
| Data processing |
Reads were mapped to hg19 genome assembly and the transfected plasmid sequences with STAR/2.7.9a (Dobin et al., 2013). Per-base read coverages were obtained with txtools (https://github.com/AngelCampos/txtools)
hg19 and the transfected plasmid (See TableS1 for sequence)
R data table (rds) file output from txtools https://github.com/AngelCampos/txtools. In addition, the TableS1.xlsx excel file contains the tranfected plasmid sequences.
