FIGURE 2.

circ_SEPT9 does not influence SEPT9 mRNA and protein level. A‐D, The relative RNA level of circ_SEPT9 was detected by qRT‐PCR in SCC‐15, HSC‐3, UM1 and SCC‐9. E, The relative RNA level of linear SEPT9 was detected by qRT‐PCR in SCC‐15. F, The relative expression of linear SEPT9 was detected by qRT‐PCR in UM1. G, Western blot was used to detect SEPT9 protein level in SCC‐15 NC and si‐circ_SEPT9 cells. H, Western blot was used to detect SEPT9 protein level in UM1 vector and circ_SEPT9 cells
