Bulk RNA-Seq of actinic keratoses. Bulk RNA-Seq of actinic keratoses

RNA-Seq was performed on 8 actinic keratoses (AK) to identify differentially expressed genes in AK vs normal skin and cutaneous squamous cell carcinoma Overall design: Total RNA was then isolated from actinic keratoses using QIAshredder (Qiagen) and Trizol (ThermoFisher) followed by DNA removal with the TURBO DNA-free ki t (Ambion) according to the manufacturer’s instructions. RNA integrity was verified using an Agilent 2100 Bioanalyzer. RNA-Seq libraries were prepared with the mRNA Seq Sample Prep K it (Illumina, Inc.) as recommended by the manufacturer. 101 bp paired-end sequencing reads were obtained using the Illumina HiSeq platform.
