1 SNHG14 confers gefitinib resistance in non-small cell lung cancer by up-regulating ABCB1 via sponging miR-206-3p. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
2 The present study aims to investigate the functions of SNHG14 in gefitinib resistance and gain insight into the underlying molecular mechanisms. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
3 In the present study, we found that SNHG14 expression was elevated and miR-206-3p expression was decreased in gefitinib-resistant NSCLC tumor tissues and cells. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
4 Functionally, SNHG14 overexpression increased gefitinib resistance by promoting cell viability, lowering apoptosis and enhancing colony forming ability, while SNHG14 knockdown reduced gefitinib resistance in NSCLC cells. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
5 Functionally, SNHG14 overexpression increased gefitinib resistance by promoting cell viability, lowering apoptosis and enhancing colony forming ability, while SNHG14 knockdown reduced gefitinib resistance in NSCLC cells. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
6 Moreover, depletion of SNHG14 enhanced the sensitivity of NSCLC cells to gefitinib in vivo. Gefitinib small nucleolar RNA host gene 14 Homo sapiens
7 Together, SNHG14 confers gefitinib resistance in NSCLC by regulating miR-206-3p/ABCB1 pathway, contributing to a better understanding of SNHG14 in acquired resistance and elucidating a candidate target to improve treatment response of NSCLC patients.
