Abstract

Particulate matter (PM) is an environmental pollutant that has been associated with an increased risk for lung cancer. PM exposure induces cellular alterations and the deregulation of cell signaling pathways. However other mechanisms such as microRNAs deregulation, might be involved in the development and progression of some types of epithelial cancer. The aim of this work was to evaluate miRNA expression in epithelial lung cells after exposure to PM10 and to identify the possible gene targets of deregulated miRNAs. We measured the expression of 2538 miRNAs using a microarray platform after 72 h of PM10 exposure; the potential biological function was inferred with bioinformatics analysis and we validated the relative expression of 10 selected miRNAs with real-time PCR. We found that the expression of 74 miRNAs was significantly changed: 45 miRNAs were downregulated and were involved in proliferation, cell cycle, cytoskeleton modification and autophagy; meanwhile, 29 miRNAs related to apoptosis, DNA damage repair and xenobiotic metabolism were upregulated.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
