Myeloid PDLIM2 repression as a common mechanism of infection susceptibility in lung diseases.

ABSTRACT:

Introduction

The PDZ-LIM domain-containing protein PDLIM2 serves as a unique tumor suppressor and immune modulator. Its repression in either lung epithelial or myeloid cells has been shown to promote lung cancer and therapy resistance. However, whether PDLIM2 plays a broader role in other lung diseases remains unclear.

Methods

Gene expression data on human samples were exploited to investigate if PDLIM2 is repressed in the lung of patients with chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD/idiopathic pulmonary fibrosis (IPF). PDLIM2 conditional knockout (KO) mice and wild type (WT) control mice were intratracheally instilled with the bacterial endotoxin lipopolysaccharide (LPS) to induce acute lung injury (ALI), a murine model of human acute
