摘要

Abstract

Vitamin D receptor (VDR) executes the main biological functions of its ligand vitamin D. VDR/vitamin D plays critical roles in regulating host immunity

maintaining barrier functions

and shaping gut microbiome. Reduction of intestinal VDR has been reported in various diseases

including inflammatory diseases and colon cancer. However

it is always challenging to get biopsies to test the pathologic changes of VDR in intestine. In the current study

we reported a simple and sensitive quantitative PCR (qPCR) method to detect reduction of intestinal VDR using fecal samples. We validated this method in several experimental models

such as colitis

bacterial infection

and aging. We further correlated the qPCR data of VDR with the protein level of VDR in colon or serum 25 (OH)D

in mice with different VDR status (VDR

+/+

VDR

+/-

and VDR

−/−

). Our data indicate that the qPCR method to test VDR using fecal samples could detect the expression level of intestinal VDR in various diseases. Our study highlights the feasibility

sensitivity

and simplicity of a molecular method to study the status of VDR as a biomarker.
