Vasohibin-2 (VASH2) is a homolog of VASH1, an endothelium-derived angiogenesis
inhibitor. Vasohibin-2 is mainly expressed in cancer cells, and has been
implicated in the progression of cancer by inducing angiogenesis and tumor
growth. Although VASH2 has been recently reported to be involved in
epithelial-mesenchymal transition (EMT), its precise roles are obscure. The aim
of the present study was to clarify the role of VASH2 in the EMT of cancer cells
in relation to transforming growth factor-? (TGF-?) signaling, which is a major
stimulator of EMT. Decreased expression of VASH2 in ovarian cancer cells
significantly repressed the expression of TGF-? type I receptor, namely activin
receptor-like kinase 5. Transforming growth factor-?1-induced phosphorylation of
Smad2 and Smad3 was markedly decreased in VASH2 knockdown cells while the
expression of Smad2 and Smad3 was unchanged. Accordingly, the responses to TGF-?1
shown by promoter assay and plasminogen activator inhibitor type 1 expression
were significantly attenuated in VASH2 knockdown cells. Furthermore, knockdown of
VASH2 in cancer cells abrogated the TGF-?1-induced reduced expression of
epithelial markers including E-cadherin, and the elevated expression of
mesenchymal markers including fibronectin, ZEB2, and Snail2, suggesting that
endogenous VASH2 is required for TGF-?1-induced EMT. In accordance with these
results, the effects of TGF-?1 on cell morphology, migration, invasion, and MMP2
expression were also abrogated when VASH2 was knocked down. These results
indicate that VASH2 played a significant role in the EMT by modulating the TGF-?
signaling. We propose that VASH2 would be a novel molecular target for the
prevention of EMT in cancers.
