microRNA‐148a‐3p inhibited the proliferation and epithelial–mesenchymal transition progression of non‐small‐cell lung cancer via modulating Ras/MAPK/Erk signaling

Son of sevenless (SOS) is one of the guanine nucleotide exchange factors that can regulate the mitogen‐activated protein kinase/extracellular signal regulated kinase signal pathway via controlling the activation of Ras. microRNAs are key regulon of gene expression and would be treated as tumor biomarkers or therapeutic targets. In this study, we find that miR‐148a‐3p acts as a tumor‐suppressor in the development and progression of non‐small‐cell...
