Abstract PR-06: Upregulation of microRNA-21 (miR-21) in human bronchial epithelial cells chronically exposed to 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) plus nicotine and modulation of these effects by diindolylmethane

Abstract: MicroRNAs (miRNAs) represent a class of naturally occurring small noncoding RNA molecules that regulate genes by either inducing mRNA degradation or inhibiting translation. The expression of miRNAs is deregulated in several cancers, including lung cancer. However, most studies have been carried out using full-blown cancer tissues and the regulation of miRNAs during early-stage tumorigenesis is unknown. In the present study, we used an in vitro model of lung tumorigenesis to assess the effect of chronic treatme… Show more
