Project description:This study sought to evaluate the diffferential gene expression of human Eosinophilic Esophagitis (EoE) patients compared to control patients. Abstract from associated publication: Eosinophilic Esophagitis (EoE) is a chronic allergic disease characterized by progressive inflammation of the esophageal mucosa. While the transcriptome of EoE has been reported, few studies have examined the genetics among both adult and pediatric EoE populations. Here, we use microarray analysis to interrogate gene expression using esophageal biopsies from EoE and Control subjects with a wide age distribution. Analysis of differential gene expression and prediction of impaired pathways was compared using conventional transcriptome analysis programs and an artificial intelligence-based ADVAITA program. Principal Components Analysis revealed samples cluster by disease status (EoE and Control) irrespective of clinical features like sex, age, and disease severity. Global transcriptomic analysis revealed differential expression of several genes previously reported in EoE (CCL26, CPA3, POSTN, CTSC, ANO1, CRISP3, SPINK7). In addition, we identified differential expression of several genes from the MUC and SPRR families, which has not been previously reported. Our findings suggest their involvement in impaired barrier integrity and loss of epidermal cell differentiation in EoE patients. These findings present two new gene families that are differentially expressed in EoE patients in both adult and pediatric populations, which presents an opportunity for a future therapeutic targets that would be useful in a large demographic of patients.

Project description:To uncover molecular drivers of Eosinophilic Esophagitis (EoE), a global proteome screen of the esophageal biopsies from individuals with and without EoE was performed.
Project description:Significant recent progress has been made with understanding eosinophilic gastrointestinal disorders (EGIDs) yet most studies have focused on eosinophilic esophagitis (EoE). Herein, we aimed to provide fundamental information about the molecular characteristics of eosinophilic gastritis (EG).
