Periostin is a secreted protein that is highly expressed in glioblastoma cells as
compared to normal brain tissue, and is therefore considered as a potential
biomarker in therapeutic modalities. Its contribution in the cancer cells
invasive phenotype is, however, poorly understood. This work investigates the
role of periostin in U-87 MG glioblastoma cell invasion, cell migration and in
Transforming Growth Factor ? (TGF-?)-induced epithelial-mesenchymal transition
(EMT). Periostin gene silencing, using small interfering RNA, decreased
TGF-?-induced mesenchymal marker expression of fibronectin and vimentin, partly
through reduced Smad2, Akt and Fak phosphorylation as well as U-87 MG cell
invasion and migration. The effects of anthocyanidins, the most abundant
diet-derived flavonoids, were examined on periostin-mediated downstream signaling
pathways. Anthocyanidins were found to decrease periostin expression whether
added under pre-, co- or post-treatment conditions along with TGF-?, and altered
the Akt and Fak signaling pathways. These effects were similar to Galunisertib
(LY2157299), a small molecule inhibitor of the TGF-? receptor I kinase. Taken
together, our data demonstrate that periostin acts as a central element in
TGF-?-induced EMT, which can be prevented by diet-derived anthocyanidins.
