The fusion gene SLC34A2-ROS1 (solute carrier family 34 member 2 and ROS proto-oncogene 1) plays an important role in non-small cell lung cancer (NSCLC) progression.
Dysregulation of SLC34A2 (NaPi2b) in tumors has attracted wide attention, but its expression and function in non-small cell lung cancer remains unclear.
Hence, our data for the first time delineated that unusual expression of SLC34A2 was modulated by miR-410, and miR-410 might positivelycontribute to the tumorigenesis and development of NSCLC by down-regulating SLC34A2 and activating Wnt/β-catenin signaling pathway.
The expressed ROS1-SLC34A2 and CCDC6-RET gene fusions from the NSCLC cell lines HCC78 and LC-2/ad, respectively, were accurately detected by the novel assay.
We selected NSCLC cell lines--A549 (KRAS G12S), NCI-H3255 (EGFR L858R), NCI-H3122 (EML4-ALK E13;A20), and HCC78 (SLC34A2-ROS1)-to evaluate the antiproliferative effects of submicromolar concentrations of the multitargeted TKIs imatinib, sorafenib, erlotinib, and crizotinib.
