Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Using tissue samples obtained from a previous study, the effect of naproxen on the gene expression profiles of antral mucosal tissue will be assessed. We hypothesize that there will be distinct changes in the gene expression profiles of samples taken from individuals treated with naproxen versus samples taken from individuals treated with placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will use microarray technology to quantify the transcriptome-wide changes in gene expression in said-samples.
