Next Generation Sequencing Facilitates Quantitative Analysis of UVB(20mJ/cm2 and 40mJ/cm2) exposed and untreated HaCaT keratinocytes Transcriptomes

Purpose: To compare the transcriptomes of UVB (20mJ/cm2 and 40mJ/cm2) exposed and untreated HaCaT keratinocytes by RNA-Seq analysis, trying to find differences in gene expression between UVB exposed and untreated of keratinocytes and then elucidate the candidate genes that may play important roles in the differentiation of UVB-induced damage in keratinocytes. Methods: HaCaT keratinocytes were subjected to 20mJ/cm2 and 40mJ/cm2 UVB irradiation. Results: To better understand the effects of UVB (20 mJ/cm2), mRNA-sequecing (n=3) were completed by Novogene Inc. A total 891 differentially expressed genes (DEGs) were identified between UV group and control group with 604 down-regulated and 287 up-regulated. A total of 4036 differentially expressed genes (DEGs) which compared with untreated group were identified by RNA-Seq, which provided abundant data for further analysis. Overall design: HaCaT mRNA profiles of UVB(20mJ/cm2 and 40mJ/cm2) and untreated group were generated by deep sequencing, in triplicate, using Illumina xten.
