Atopic Dermatitis, Psoriasis and healthy control RNA-seq cohort


ABSTRACT: To gain a deeper understanding of the pathophysiology of AD, we conducted a large-scale transcriptomic study of AD with deeply-sequenced RNA-seq samples using long (125b) paired-end reads. By integrating deep sequencing-based skin transcriptome profiling with systems biology analysis, we are able to provide deep characterization for the expression signatures for AD, and by including psoriasis samples in the analysis, we can reveal the distinct molecular features of uninvolved and lesional skin of AD that have not been previously described. Overall design: We performed high-depth sequencing of 147 skin transcriptomes obtained from a carefully matched and tightly defined cohort of 27 AD patients, 28 PSO patients, and 38 healthy controls, whom were recruited within an ongoing investigator-initiated clinical study to identify shared and distinct disease mechanisms of AD and Psoriasis.

Atopic dermatitis (AD) affects up to 20% of children and adults worldwide. To gain a deeper understanding of the pathophysiology of AD, we conducted a large-scale transcriptomic study of AD with deeply sequenced RNA-sequencing samples using long (126-bp) paired-end reads. In addition to the comparisons against previous transcriptomic studies, we conducted in-depth analysis to obtain a high-resolution view of the global architecture of the AD transcriptome and contrasted it with that of psoriasis  ...[more]
