Fig. 3: MiR-21-silencing activity in HeLa and IGROV1 cells of Fol-miR21-NCs compared to Fol-scr-NCs.

qPCR analysis of miR-21 expression level is reported for HeLa (A) and IGROV1 (B) cells incubated with Fol-NCs for different time intervals. Values are expressed as mean ± S.E.M. of three different independent experiments. Statistical significance: *P < 0.05, **P < 0.01, and ***P < 0.001 (Student’s t-test). Values below detection limit (•).
