Figure 10. Hypothetical mechanism of luteolin mediation of neurite outgrowth in PC12 cells.

Figure 10

Luteolin induces the up-regulation of miR-132, which may serve as a mediator for neurite outgrowth through the activation of cAMP/PKA- and ERK-dependent CREB signaling pathways in PC12 cells. In addition, ERK- or PKC-dependent but CREB/miR-132-independent pathways may also partially contribute to the mediation of neurite outgrowth by luteolin in PC12 cells.
