Objective To explore the regulatory network of dysregulated microRNAs and mRNAs and related signaling pathways in peripheral mononuclear cells(PBMCs)of cigarette smokers.Methods The peripheral venous blood was taken from20 healthy non-smokers and 17 healthy smokers.The miRNA and mRNA expression profile of PBMCs was examined by miRNA and mRNA array.The regulatory relationship between dysregulated miRNAs and mRNAs was predicted and the signaling pathways were enriched.Results Compared with the healthy non-smo...
