Sample GSM4203374 Query DataSets for GSM4203374
Status Public on Jun 29, 2020
Title hMSCs MoS2 1
Sample type SRA
Source name Mesenchymal stem cells
Organism Homo sapiens
Characteristics cell type: Bone marrow derived mesenchymal stem cells
Treatment protocol hMSCs were cultured and treated with/without low-intensity NIR exposure and/or exfoliated MoS2 (25 µg/mL, 48 h).
Growth protocol hMSCs were cultured under normal media conditions consisting of α-minimal essential media (alpha-MEM, Hyclone, GE Sciences) with 16.5% fetal bovine serum (Atlanta Biologicals, USA) and 1% penicillin/streptomycin (100 U/100 µg/mL, Gibco). After every 2-3 days, half of culture media was exchanged for fresh media. Cells were passaged with 0.5% trypsin-EDTA upon reaching confluency of ~70% and seeded at ~2500 cells/cm2. All experiments were completed with cell populations under P5.
Extracted molecule total RNA
Extraction protocol At the end of 7 days of culture, total RNA was extracted (High Pure RNA Isolation, Roche Life Sciences), and then converted into cDNA (>1 μg).
RNA libraries were prepared for sequencing using standard Illumina protocols
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
Description MoS2 treatment
Data processing Sequence cluster identification, quality prefiltering, base calling and uncertainty assessment were done in real time using Illumina's NCS 1.0.2 and RFV 1.0.2 software with default parameter settings. Sequencer .cbcl basecall files were demultiplexed and formatted into .fastq files using bcl2fastq 2 2.19.0 script
Sequenced reads were trimmed for adaptor sequence and aligned by STAR aligner
Fragments Per Kilobase of exon per Megabase of library size (FPKM) were calculated. In short, exons from all isoforms of a gene were merged to create one meta-transcript. The number of reads falling in the exons (excluding 5UTR and 3UTR) of this meta-transcript were counted and normalized by the size of the meta-transcript and by the size of the library (only reads mapping to annotated regions of the genome were used for the total libraray size).
