Fig. 4From: Alpinia oxyphylla Miq. fruit extract activates IGFR-PI3K/Akt signaling to induce Schwann cell proliferation and sciatic nerve regenerationAOF extract induces the expression of proteins involved in the cell cycle in a dose-dependent manner. RSC96 cells were stimulated with AOF for 24 h. The protein expressions of cell cycle regulatory proteins were determined by western blot analysis. Treatment with AOF upregulated cyclinD1, cyclinE and cyclinA in a dose-dependent manner. α-tubulin was used as a loading controlBack to article page
