miR-30a-3p plays a tumor suppressor role in NSCLC with Osimertinib resistance. A Successful establishment of miR-30a-3p overexpression and knockdown cellular models: miR-30a-3p mimic and inhibitor and subsequently stably transfected them into PC9/OR and HCC827/OR cells, respectively. The transfection efficiency was assessed by RT-qPCR. B Cell counting kit-8 (CCK8) assay was conducted to determine the IC50 value of Osimertinib. C Soft agar colony assay was employed to assess colony formation ability. D Transwell chamber assay was performed to analyze cell invasion ability. F and Annexin V-FITC/PI assay was performed to investigate cell apoptosis. *P < 0.05, **P < 0.01. Osimertinib Sensitive; OR: Osimertinib Resistance. circ_100696: circ_PPAPDC1A
