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.

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.
