Sample GSM4061957 Query DataSets for GSM4061957
Status Public on Dec 01, 2020
Title HeLa_WT_RRBS
Sample type SRA
 
Source name HeLa
Organism Homo sapiens
Characteristics cell line: HeLa
genotype/variation: wild type
Treatment protocol No treatment.
Growth protocol Human cervical cancer cell line (HeLa) was maintained in DMEM medium (Gibco) containing 10% fetal calf serum (Gemini), 100 U/mL penicillin and 100μg/mL streptomycin (Milipore). Human colon cancer cells (HCT116) was maintained in McCoy’s 5A medium (Gibco) containing 10% fetal calf serum (Gemini), 100 U/mL penicillin and 100μg/mL streptomycin (Milipore). The cultured cells were maintained at 37 °C in a humidified incubator with 5% CO2.
Extracted molecule genomic DNA
Extraction protocol To prepare genomic DNA for RRBS analysis, cells were resuspended with cell lysis buffer (10mM Tris pH 7.5, 10 mM EDTA, 10 mM NaCl, 0.5% sarcosyl, 0.1 mg/mL RNase (CWBIO)) and incubated at 37°C overnight. Then, protease K was added to a final concentration of 0.2 mg/mL and incubated at 65°C for 24 hr. Genomic DNA was extracted by phenol/chloroform and ethanol precipitated. The DNA were dissolve in ddH2O.Total RNA for RNA-seq analysis was extracted from cells using RNAiso Plus Reagent (Takara) according to the manufacturer’s instructions.

Data processing RRBS reads were mapped to human genome hg38 by bismark (v0.19.0) . Only unique mapped reads were kept and CpGs with >= 5 reads mapped were used for further analysis. Paired-end 2 replicates RNA-seq reads for HeLa wild type and LSH KO cells were mapped to hg38 by STAR (v2.4.0d) and then quantified by Cuffdiff (v2.2.1) . Differentially expressed genes (DEGs) were required p-value<=1e-2 and fold change >=2 as reported by Cuffdiff.
Supplementary_files_format_and_content: The RRBS processed data were the output of bismark tab-delimited text file for each sample. For RNA-seq data the cuffdiff output differential expressed genes with name of gene_exp.diff were used.
