Fig. 4: circRNA_104670 promotes apoptosis and inhibits the proliferation of NP cells.

a–c Cell flow cytometry was carried out to explore the NP cell viability at 2 and 4 weeks after the si-miRNAs were co-transfected into NP cells. The plots shown on the button left indicate normal NP cells, the plots shown on the bottom right indicate early apoptotic NP cells, the plots shown on the top right indicate late apoptotic NP cells and the plots shown on the top left indicate necrotic NP cells. d An MTT assay was performed in NP cells at 0, 24, 48, and 72 h after transfections. *p < 0.05; **p < 0.01
