Sample GSM7890456 Query DataSets for GSM7890456
Status Public on Nov 27, 2023
Title AG12851 with hTERT and ex527 replicate 1
Sample type SRA
 
Source name Skin
Organism Homo sapiens
Characteristics tissue: Skin
cell line: AG12851
cell type: Human skin fibroblast
treatment: AG12851 with hTERT and ex527
Biomaterial provider Coriell Cell Repositories https://catalog.coriell.org/0/Sections/Search/Sample_Detail.aspx?Ref=AG12851
Treatment protocol Fibroblast cells were immortalized by human Telomerase Reverse Transcriptase protein (hTERT). Cells were then cultured on a cover glass and treated with and without EX527 (1uM for 48hr). The SIRT1 gene was deleted from the cancer cell lines using CRISPR-Cas9 targeting exon1.
Growth protocol Fibroblasts were grown in MEM medium, 15% FBS
Extracted molecule genomic DNA
Extraction protocol DNA from cell cultures was isolated, size fractionated and subject to exonuclease digestion as described in Aladjem et al., Science 281, 1005, 1998. and Wang et al., Molecular and Cellular Biology 24:3373-86, 2004. For ChipSeq, DNA molecules were enriched using antibodies against proteins of interest.
Samples were eluted, and then purified by Monarch PCR & DNA Cleanup Kit (NEBT1030S). 100 ng of NS samples were used to generate the library. The kits used for the library were NEBNext Ultra II DNA Library Prep Kit for Illumina (NEB, E7805S) and NEBNext Multiplex Oligos for Il-lumina (Index Primers Set 1 and Set 2) (NEB, E7335S and E7500S).
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NovaSeq 6000
 
Data processing BAM files were filtered using alignmentSieve to remove reads shorter than 40bp
For nascent strand peak calling the MACS2 algorithm was used.
Nascent strand reads were called by comparison to genomic DNA.
Peaks were filtered to accept the top 40% by q-value based on the raw output
Assembly: T2T
Supplementary files format and content: Bed file format of replication origin peaks
Supplementary files format and content: BigWig file format of replication origin locations
Library strategy: NS-seq
