Sample GSM7102586 Query DataSets for GSM7102586
Status Public on May 29, 2024
Title L3 animals with dat-1_NanoDam control, replicate 1
Sample type SRA
Source name Dopaminergic Neurons
Organism Caenorhabditis elegans
Characteristics tissue: Dopaminergic Neurons
sample type: Specific expression of Dam in target tissue
strain: TV27654
genotype: bmd261
developmental stage: L3
Growth protocol Animals grown for 3 generations on Dam- bacteria (E. coli ER2925 from NEB) were bleach synchronized and L1s were grown at 25C until the L3 stage (24h after putting L1s on food). Approximately 5000 synchronized worms were harvested, washed with M9, then snap frozen in liquid nitrogen and stored at -80C.
Extracted molecule genomic DNA
Extraction protocol gDNA was harvested using a Qiagen DNeasy Tissue and Blood kit (#69504) with no deviations from standard protocols.
DamID amplicons were obtained as previously described (Gomez-Saldivar et al., 2021) using 4 initial PCR cycles followed by 19 additional cycles. DamID amplicons were directly barcoded through blunt end ligation and sequenced using Oxford Nanopore library reagents (LSK-109, NBD-104, NBD-114)

Instrument model MinION
Description MinION Mk1C
Data processing Nanopore sequences were basecalled and demultiplexed using guppy 3.6 onboard a MinION Mk1C device, only base calling reads with a Q score higher than 8.
Fastq files were combined together using the UNIX command 'cat' and mapped to the ce10 genome using minimap2 with the options '-ax map-ont' to output .sam files.
SAM files were sorted and converted to bam using samtools.
Sorted .bam files and a file mapping all GATC sequences in C. elegans were fed into damidseq_pipeline (Marshall and Brand, 2015) to obtain bedgraph files.
Bedgraphs were analyzed for peaks using find_peaks (Owen Marshall).
Assembly: ce10
Supplementary files format and content: .bedgraphs represent the comparisons between the NanoDam alone control vs. NanoDam binding to a transcription factor
Supplementary files format and content: .gff files represent the called peaks after analysis of the .bedgraph files
