To identify microRNAs (miRNAs, miRs) with potential roles in lung fibrogenesis, we performed genome-wide profiling of miRNA expression in lung tissues from a silica-induced mouse model of pulmonary fibrosis using microarrays. Seventeen miRNAs were selected for validation via qRT-PCR based on the fold changes between the silica and the control group. The(More)
Coal workers’ pneumoconiosis (CWP) is characterized by fibrosing nodular lesions that eventually develop into progressive pulmonary fibrosis. Genetic variations have been recognized to be involved in the multi-factorial susceptibility to CWP, and MUC5B is a candidate lung fibrosis susceptibility gene. In the present study, we investigated possible genetic(More)
Coal workers' pneumoconiosis (CWP) has been associated with abnormalities in the extracellular matrix remodeling, as well as aberrant matrix metalloproteinases (MMPs) in lung tissues. We investigated the association of three functional polymorphisms in MMP gene promoters (MMP1 rs1799750, MMP2 rs2285053 and MMP3 rs522616) with the risk of CWP. A total of 693(More)
BACKGROUND Glucocorticoid-induced tumor necrosis factor (TNF) receptor-related protein (GITR) mainly affects the functions of effector T cells and regulatory T cells thus it may influence various diseases. Coal workers' pneumoconiosis (CWP) is a serious occupational disease worldwide. In the present study, we examined the association between the functional(More)
BACKGROUND The SPARC is a crucial matricellular protein and may influence the course of various diseases like tumor metastasis and fibrosis. In the present study, we investigated the association between the potential functional polymorphisms in SPARC and coal workers' pneumoconiosis (CWP) risk in a Chinese population. METHODS Five potentially functional(More)
BACKGROUND The interleukin 17A (IL-17A) which is located on chromosome 6p and has been linked to chronic inflammation, is an important candidate gene conferring coal workers' pneumoconiosis (CWP). The purpose of this study was to investigate the genetic association between single nucleotide polymorphisms (SNPs) of IL-17A and CWP in a Chinese population. (More)
BACKGROUND Pneumoconiosis is a serious occupational disease worldwide, which is characterized by irreversible and diffuse lung fibrotic lesions. Laminin beta 1(LAMB1) is widely expressed in tissues and it is crucial for both lung morphogenesis and physiological function. In this study, we explored the association between LAMB1 rs4320486 and risk of(More)
BACKGROUND The matrix metalloproteinase-7 (MMP-7) and osteopontin (OPN) are both multifunctional proteins with roles in inflammation, cell proliferation, tissue remodeling and so on, implicated in the pathogenesis of numerous conditions including pulmonary fibrosis. In this study, we investigated the associations between the potential functional(More)
OBJECTIVE To explore whether the tagging single nucleotide polymorphisms (SNPs) within EPHX1 gene were involved in the genetic susceptibility to coal worker's pneumoconiosis (CWP) by case-control study. METHODS This study consisted of 697 CWP patients and 694 controls. All the subjects were Han Chinese, underground coal miners and recruited from coal(More)
