Hsa_circ_0000190 Promotes NSCLC Cell Resistance to Cisplatin via the Modulation of the miR-1253/IL-6 Axis

Figure 1

DDP-resistant NSCLC tissues and cells lines exhibit hsa_circ_0000190 upregulation. (a) Hsa_circ_0000190 levels were assessed via qPCR in NSCLC tumor tissues harvested from DDP-resistant (n = 73) and DDP-sensitive (n = 63) patients. (b) Hsa_circ_0000190 levels were analyzed in NSCLC cell lines, DDP-resistant NSCLC cell lines, and control HBE1 cells via qPCR. (c) The closed covalent loop nature of hsa_circ_0000190 was evaluated through treatment with RNase R, using the linear CNIH4 transcript as a control. (d) Actinomycin D treatment was used to inhibit transcription in order to evaluate hsa_circ_0000190 stability, using the linear CNIH4 transcript as a control. (e) A PARIS™ Kit Protein and RNA Isolation system was used to evaluate the subcellular localization of hsa_circ_0000190. .
