**2.6 Ivermectin-related lncRNAs verified with qRT-PCR**

TRizol® Reagent (Invitrogen, CA, USA) was used to extract total RNAs of cells TOV21G and A2780 treated with different concentration of ivermectin (0 μM, 10 μM, 20 μM, and 30 μM). The extracted total RNAs was reversely transcribed into cDNAs for qRT-PCR analysis of each lncRNA expression, including KIF9-AS1, HCG15, PDCD4-AS1, ZNRF3-AS1, ZNF674-AS1, LINC00565, SOS1-IT1, WWTR1- AS1, PLCH1-AS1, LINC00517, SNHG3, STARD13-IT1, AL109767.1, HOXC-AS3, LEMD1-AS1, and LBX2-AS1. Beta-actin was set as internal control for qRT-PCR analysis. The detailed procedure was described previously [4].
