Figure 7. Berberine and cinnamaldehyde together suppressed A549 cell autophagy.

Berberine and cinnamaldehyde together aborted berberine- or cinnamaldehyde-induced cell autophagy under 10% serum culture conditions (n = 3) (A). Combination therapy suppressed autophagy under 2% serum culture condition (n = 3) (B). Cells in the AO staining group were in the early stage of culture medium replacement. Cells in the LC3-B staining group were harvested at a late cell culture stage. *P < 0.05, **P < 0.01 vs control.
