RNA-seq approach to study the specific effects of SREBF1-depleting antisense oligonucleotide (ASO) reagent in human melanoma cells.
Purpose: Detailed exploration of de novo Fatty Acid Synthesis (DNFA) transcription regulation and clinical relevance in melanomas. This study was designed to achieve the following goals: 1) determine the impact of SREBP1 depletion on gene expression in metastatic melanoma cells; 2) determine the specificity of ASO and other reagents inhibiting SREBF1 mRNA.  Method: RNA-Seq was performed after culture with control and various SREBF1-depleting agents, including pooled siRNAs and individual ASOs, in HT-144 cells.  Results: using STAR, we mapped about 2 X 4 million pair-end sequence reads per sample to the human genome (build GRCh38.94) and identified around 2 million annotated transcripts per sample. Overall design: 6 RNA samples (4 technical replicates for each biological sample) were sequenced (paired-end) on a NextSeq® 500 sequencer (Illumina). RNA sequence alignment was performed on the 24 pairs of FASTQ files from the sequence results.
