The Essential Oil from Acori Tatarinowii Rhizome (the Dried Rhizome of Acorus tatarinowii Schott) Prevents Hydrogen Peroxide-Induced Cell Injury in PC12 Cells: A Signaling Triggered by CREB/PGC-1α Activation

Figure 7

Activation of CREB was involved in the cytoprotective effects of ATEO in PC12 cells. To further elucidate the molecular mechanism underlying ATEO-induced PGC-1α expression and cytoprotection is CREB-dependent, the phosphorylation level of CREB (a), protein level of PGC-1α (b), mRNA level of anti-oxidant proteins (c) and MTT assay (d) were assessed in H89 (5 μM) pretreated-PC12 cells, as earlier mentioned. ATEO (15 μg/mL) was used in the study. β-actin served as an internal control. Data are expressed as mean ± SEM, where n = 3. , ATEO-treated vs. (H89 + ATEO)-treated group; , H2O2-treated ATEO vs. H2O2-treated (H89 + ATEO) group.
