lncRNA CASC2 Enhances 131I Sensitivity in Papillary Thyroid Cancer by Sponging miR-155
Figure 2
Continuous exposure to 131I induces tolerance of papillary thyroid cancer cells. (a, b) TPC-1 and IHH-4 cells were treated with 131I, and 131I-resistant cells (res-TPC-1 and res-IHH-4) were obtained after 8 generations. The IC50 of 131I was analyzed by MTT assay. (c, d) Flow cytometry was conducted to measure cell apoptosis in TPC-1, res-TPC-1, IHH-4, and res-IHH-4 cells after treatment of the indicated dose of 131I for 12 h. and ; NS: not significant.
