Title |
RNAseq - LS180 cells, SOX9_dox_pos_rep1 |
Sample type |
SRA |
|
|
Source name |
LS180
|
Organism |
Homo sapiens |
Characteristics |
cell type: Colorectal Cancer cells cell line: LS180 doxycycline induction: + expression: Doxycycline induced overexpression of V5-tagged wildtype SOX9
|
Treatment protocol |
GFP, SOX9 and mutant SOX9 was induced by doxycycline (0.5 µg/ml) for 24h. Each experiment was performed in duplicates.
|
Growth protocol |
LS180 cell line was obtained from Millipore Sigma and cultured in DMEM + 2mM Glutamine + 15% Fetal Bovine Serum (FBS) + 1% (P/S).
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was extracted using RNeasy Mini kit (Qiagen) according to the manufacture`s instruction. Matured mRNA fraction was captured and enriched via oligo(dT) beads, then mRNAs were fragmented randomly in fragmentation buffer and the first-strand cDNA is synthesized using random hexamer primers and M-MuLV Reverse Transcriptase (RNase H-). The second strand was subsequently generated by dNTPs, DNA polymerase I and RNase H. Double-stranded cDNA molecules were purified by AMPure XP beads and overhanging ends are repaired to blunt ends by exonuclease/polymerase. After 5’ phosphorylation and 3’ adenylation, the cDNAs were ligated with P5/P7 sequencing adapters, then size selection (insert fragment of preferentially 150~200 bp in length) and library purification was performed using AMPure XP system (Beckman Coulter, Beverly, USA). The final library was created by amplification and subsequent AMPure XP beads purification. RNA-Seq was performed using 150-bp paired-end sequencing chemistry (Illumina) at Novogene core facility.

Data processing |
Illumina Casava1.7 software used for basecalling. Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to hg38 whole genome using STAR 2.7.0a A gene count matrix was obtained using featureCounts on bam files Genome_build: hg38 Supplementary_files_format_and_content: featureCounts_HT115.txt Supplementary_files_format_and_content: normalized_counts.xls
