NOTCH1 and non-small cell lung carcinoma: To test whether PVT1 regulates invasion of NSCLC cells throughactivation of NOTCH1 signaling and epithelial-mesenchymal transition (EMT), expression ofYAP1, NOTCH1, NICD and HES1 were assessed in A549 and H1299 cells after YAP1 knockdownwith or without PVT1 overexpression co-transfection.
