Long noncoding RNAs as Tumorigenic Drivers and Therapeutic Targets)
Abstract Objective: Osimertinib can selectively inhibit both epidermal growth factor receptor (EGFR) sensitizing and T790M gatekeeper mutations, and has shown remarkable therapeutic effects in patients with lung adenocarcinoma. However, almost all patients inevitably develop drug resistance. Herein, we sought to
clarify the roles of exosomal lncRNA H19 in modulating osimertinib resistance, focusing on the PI3K-PTEN-Akt signaling axis.
Methods: Functional assays, including cell viability assay, colony formation, cell apoptosis and xenograft mouse, employed in evaluate the effects of exosomal lncRNA H19 on cell growth and apoptosis. RNA quantitation and western blot were adopted to demonstrate the regulatory roles of…
