Fig. 4: Expression level of PTEN and Pdcd4 miR-21 target proteins.

A Western blots of PTEN in HeLa and IGROV1 cells lysates, treated or not with Fol-NCs for 48 h. B Western blot of Pdcd4 on lysates from HeLa cells treated or not with Fol-NCs for 72 h. Densitometric analysis of three different experiments are shown on the right panels. Values are expressed as mean ± S.E.M. Statistical significance: *P < 0.05 and ***P < 0.001 (Student’s t-test).
