The Role of the LINC01376/miR-15b-3p_R-1/FGF2 Axis in A549 and H1299 Cells EMT Induced by LMW-PAHs.

ABSTRACT: Low-molecular-weight polycyclic aromatic hydrocarbons (LMW-PAHs), such as the 400 μM mixture of phenanthrene and fluorene used in this study, are prevalent environmental pollutants. Induction of epithelial-mesenchymal transition (EMT) by LMW-PAHs promote cell invasion and migration and contribute to disease pathogenesis. Long non-coding RNAs (lncRNAs) regulate gene expression by acting as competing endogenous RNAs (ceRNAs) that sequester microRNAs (miRNAs), a mechanism important for modulating EMT. Previously, regulation of the PI3K/AKT pathway and EMT in A549 cells are shown to occur through the hsa_circ_0039929/miR-15b-3p_R-1/FGF2 axis. Here, the functional role of the related LINC01376/miR-15b-3p_R-1/FGF2 axis in LMW-PAH-induced EMT was examined in A549 and H1299 cells. The miR-15b-3p_R
