Exosomal circGDI2 regulated SCAI expression through sponging miR-424-5p. (A) Correlation between circGDI2 expression and SCAI mRNA level in OSCC tissues using the Spearman test. CAL-27 and SCC-15 cells (Recipient cells) were transfected with miR-424-5p mimic or miR-NC mimic and then treated with 30 µg/mL of the exosomes from pcDNA-NC- or pcDNA-circGDI2-transfected Donor cells, followed by the measurement of SCAI mRNA expression by qRT-PCR (B and C), SCAI protein level by Western blot (D and E). Blots were representative of n = 6. *P < 0.05.
Abbreviations: pcDNA-NC-exo, exosomes derived from OSCC cells transfected with pcDNA; pcDNA-circGDI2-exo, exosomes derived from OSCC cells transfected with pcDNA-circGDI2.
