The Association of Transgelin-2, Metallothionein-2 and Ezrin With Asthma

The Association of Transgelin-2, Metallothionein-2 and Ezrin With Asthma: A Case-control Study

Asthma is one of the most common chronic respiratory diseases. Previous study found a series of differentially expressed genes and proteins (transgelin-2, metallothionein-2, ezrin) in asthmatic rat. The aim of the study is to investigate the changes and associations of these gene with asthma in human.

Study Overview

• Status: Recruiting
• Conditions: Asthma
• Intervention / Treatment: Diagnostic test: No intervention

Detailed Description

This study will investigate the changes and associations in asthma. In this project, the investigators will explore the changes of gene expression of transgelin-2, metallothionein-2 and ezrin in asthma and investigate their correlation with current diagnosis markers of asthma, including pulmonary function, fractional exhaled nitric oxide,eosinophil counts,immunoglobulin E, interleukin-5, etc.
