Official title

Chitinases and TGFB in Human Asthma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to find out the roles of two specific gene families (the chitinase gene family and the TGFB family). We hypothesize that chitinases and TGFb pathway genes will be differentially expressed in the airways of non-asthmatic subjects and subjects with asthma. We further hypothesize that genetic variants in CHIT1, AMCase, and TGFb pathway genes that show associations with asthma and related phenotypes will change the expression and/or function of the protein of these genes in the airway in several ways, including the transcript numbers for full length genes and splice variants and, for the chitinase genes, the levels of chitinase activity in airway secretions.
