| Title |
MCTX-C9-ALS-1_MeRIP |
| Sample type |
SRA |
| |
|
| Source name |
human post-mortem motor cortex
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: human post-mortem motor cortex
genotype: fALS
|
| Growth protocol |
iPSCs were maintained in mTeSR media on Matrigel, following the Cedars-Sinai Standard Operating Procedure (SOP, https://www.cedars-sinai.edu/content/dam/cedars-sinai/research/documents/biomanufacturing/complete-ipsc-culturing-protocol-rev-4-2020.pdf). iPSCs were differentiated into spinal neurons using the direct induced motor neuron protocol. All cells were maintained at 37°C with 5% CO2.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from cells using TRIzol (Thermo Fisher). Ribosomal RNAs were further depleted from total RNA by RiboMinus Eukaryote Kit v2 (Thermo Fisher Scientific). m6A-immunoprecipitation (m6A-IP) was performed using the EpiMark N6-Methyladenosine Enrichment Kit (New England Biolabs) following the manufacturer’s protocols.
Library preparation was performed using the SMARTer Stranded Total RNA-Seq Kit v2 (Takara).

| Data processing |
Raw reads were trimmed with Trimmomatic-0.39, then aligned to human genome and transcriptome (hg38) using HISAT (version 2.1.0) with ‘--rna-strandness RF’ parameters.
Mapped reads were separated by strands with samtools (version 1.9) and m6A peaks on each strand were called using MACS (version 2) with parameter ‘-nomodel, --keep-dup 5, -g 2.052e9, --tsize 60 -extsize 150’ separately.
Assembly: hg38
Supplementary files format and content: Tab-delimited peak locations together with peak summit, pvalue and qvalue reported by MACS2 for each sample.
