SOX2 and neoplasm: YAP1 expression is elevated and correlates with tumor staging and an increase in Hippo target genesSuppression of YAP promotes differentiation, and decreases cell proliferation and tumor growthYAP is a direct target of SOX2 in osteoprogenitors and YAP1 expression is altered by SOX2 abundanceOS transgenic mice with upregulated Hedgehog signaling display high YAP1 expressionThe long non-coding RNA H19 is aberrantly induced by YAP1 overexpression
