Abstract

To examine whether there was an association between epithelial neutrophil activating peptide 78 (ENA-78), interferon-inducible protein 10 (IP-10), vascular endothelial growth factor (VEGF) polymorphism and Chinese patients with idiopathic pulmonary fibrosis (IPF). Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were performed to analyze the gene polymorphisms of ENA-78 (-156G/C), IP-10 (-1596C/T) and VEGF (+405G/C) in 60 IPF patients and 60 controls with trauma or bone fracture matched in age, gender and smoking status. The distribution of carrying GC + CC genotype frequency (20.0%) and C allele frequency (12.7%) for ENA-78 in IPF patients was significantly higher than that in healthy controls [6.7% (P = 0.032) and 3.3% (P = 0.008), respectively], the relative risk of suffering from IPF of -156C allele gene carrier significantly increased (OR = 4.23, 95%CI: 1.35-13.20). The distribution of carrying CT + TT genotype frequency (10.0%) and T allele frequency (5.8%) for IP-10 in IPF patients was significantly lower than that in healthy controls [26.7% (P = 0.018) and 14.2% (P = 0.031), respectively], the relative risk of suffering from IPF of -1596T allele gene carrier decreased (OR = 0.38, 95%CI...Continue Reading
