Sample GSM8541008 Query DataSets for GSM8541008
Status Public on Nov 13, 2024
Title hAFSC-iPSC-Cardiomyocyte-lac bio_rep3
Sample type SRA
 
Source name Amniotic fluid stem cell
Organism Homo sapiens
Characteristics tissue: Amniotic fluid stem cell
cell line: AFSC-iPSC
cell type: Amniotic fluid stem cell-induced pluripotent stem cell
genotype: wild-type
treatment: Glucose-Depleted and Lactate-Supplemented Conditions
Treatment protocol The hPSCs were differentiated followed the well-established 14 days protocol by Burridge et al (2014). On day 0, the RPMI-1640 medium contains B27 minus insulin supplement (Thermo; 1895201) and Wnt activator Chir99021 (5 µM; Stemcell Technology; 72054). On Day 2, medium was changed to RPMI-1640 supplemented with B27 minus insulin. On day 3, addition of Wnt inhibitor IWR-1 (5 µM; Sigma; I0161) to the medium. On day 7, addition of insulin (B27 supplement; Thermo; 17504044) to induce cardiomyocyte formation. The medium was changed every 2 days untill the completion of the 14 days protocol.
Growth protocol All hPSCs include hiPSCs and hESC were cultured on Matrigel matrix (Corning; 354230) pre-coated cell culture dish in Stemflex medium (Thermo; A3349401). Addition of ROCK inhibitor Y27632 (10uM; Cayman; 10005583) allows cells to attach.
Extracted molecule polyA RNA
Extraction protocol Total RNA was purifed with Direct-zol RNA MiniPrep kit (Zymo) and treated with DNAse I followed manufactorers instruction. Purify the poly(A) RNA sample by Dynabeads mRNA DIRECT purification kit (Thermo) with twice purification process, followed by bisulfite conversion reaction with three cycles of 70℃ 10minutes and 64℃ 45 minutes by EZ RNA methylation kit (Zymo).
The bisulfite treated mRNA samples librarires were generated with NEBNext Ultra II Directional RNA Library Prep Kit for Illumina (New England Biolabs)

Data processing The raw fastq file were merge into one R1 and one R2 file by Concatenate datasets tool on Galaxy web platform.
Use Trim Galore! tool remove reads with Q score less than 20 and the adaptor seqeunces. With the followed arguments: for read 1 ‘-j 1 -e 0.1 -q 20 -O 1 -a AGATCGGAAGAGCACACGTCTGAACTCCAGTCAC’ and read 2 ‘-j 1 -e 0.1 -q 20 -O 1 -a AGATCGGAAGAGCGTCGTGTAGGGAAAGAGTGTAGATCTCGGTGGTCGCCGTATCATT’
The trimmed and quality reads were aligned to human reference genome GRCh38 (Release-100 from Ensembl website) with gene transfer format (GTF) by meRanGh align, and with arguments of maximum mismatch ratio set at 0.1 (‘-mmr 0.1’).
The SAM files were then proceed to meRanCall with arguments ‘-rl 150 -md 5 -ei 0.1 -cr 99 -fdr 0.05 -mcov 10 -mr 0.05’ to identifiy m5C sites
The gene annotaion of m5C sites were retrieved by meRanAnnotate with arguments of ‘-f 'gene' -g Homo_sapiens.GRCh38.100.gff3‘
Assembly: hg38
Supplementary files format and content: excel file with m5C sites commonly present in preplicates
Supplementary files format and content: excel file with differential gene expression data between groups
Supplementary files format and content: tab-delimited txt files of HTseq-count reads counts of each sample
