Sample GSM4504170 Query DataSets for GSM4504170
Status Public on Aug 11, 2020
Title NC1-Input
Sample type SRA
 
Source name HCCLM3 cells
Organism Homo sapiens
Characteristics cell line: HCCLM3 cells
cell type: hepatocellular carcinoma
genotype/variation: ALKBH5 -normal
merip antibody: none
Treatment protocol HCCLM3 cells were transfected with lentiviruses expressing Flag-ALKBH5 (OE groups) or empty vector (NC groups) (MOI=30). They were then filtrated using 3-5 μg/ml puromycin for more than one week until the efficiency was examined by qPCR and immunoblot analysis.
Growth protocol HCCLM3 cells were incubated at 37°C in 5% CO2 incubator with the humidified environment. And they were cultured with Minimum Essential Media (MEM) which were routinely supplemented with 10% fetal bovine serum (FBS).
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with TRIzol reagent.
mRNA was enriched from total RNA with Poly(A) mRNA Magnetic Isolation Module(NEB#E7490) before fragmented chemically to ~150 nts long size, 10% fragmented mRNA was saved as Input sample while the rest part was subjected to IP using anti-m6A antibodies(Synaptic system#202 003). After stringent washing, bound RNA was eluted by competition with N6-methyladenosine (Sigma-Aldrich#M2780) as IP samples. IP and input library construction was carried out simultaneously with VAHTS Total RNA-seq (H/M/R) Library Prep Kit for Illumina (Box2&3, Vazyme#NR603). Qualities of each library were validated using an Agilent 2100 Bioanalyzer, and successful libraries of sample pairs (input and IP) were sequenced on illumina Novaseq sequencer with PE150 strategy.
MeRIP-seq
 
Library strategy RIP-Seq
Library source transcriptomic
Library selection other
Instrument model Illumina HiSeq 4000
 
Data processing Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence.
For meRIP seq, after removal of rRNA and tRNA, sequenced reads were mapped to hg19 using hisat2-align-s (v2.0.5). PCR duplicates were further removed with Picard (v2.16.0) and high quality mapped reads were extracted by samtools view (v0.1.09) “-q 30”. Differenct Regions enriched in the meRIP RNA samples over input RNA samples were identified as m6A peaks using exomePeak(v2.6.0) peak-caller.
Genome_build: hg19
Supplementary_files_format_and_content: Supplementary_files_format_and_content: bed files were generated using exomePeak.
