Recent genetic screens of fly mutants and molecular analysis have revealed that the Hippo (Hpo) pathway controls both cell proliferation and cell death. Deregulation of its human counterpart (the MST pathway) has been implicated in human cancers. However, how this pathway is linked with the known tumor suppressor network remains to be established. RUNX3 functions as a tumor suppressor of gastric cancer, lung cancer, bladder cancer, and colon cancer. Here, we show that RUNX3 is a principal and evolutionarily conserved component of the MST pathway. SAV1/WW45 facilitates the close association between MST2 and RUNX3. MST2, in turn, stimulates the SAV1-RUNX3 interaction. In addition, we show that siRNA-mediated RUNX3 knockdown abolishes MST/Hpo-mediated cell death. By establishing that RUNX3 is an endpoint effector of the MST pathway and that RUNX3 is capable of inducing cell death in cooperation with MST and SAV1, we define an evolutionarily conserved novel regulatory mechanism loop for tumor suppression in human cancers.

Studies reported that miR-590-3p was involved in human cancer progression. However, its roles of oncogene or anti-oncogene in malignancies still remain elusive. This study was aimed to investigate the effect of miR-590-3p on the cell proliferation and metastasis via Hippo pathway in colorectal cancer (CRC). In our study, miR-590-3p was demonstrated highly expressed in CRC tissues, compared with adjacent normal tissues (P<0.05). In addition, miR-590-3p was positively associated with TNM stage and distant metastasis. Survival analysis showed that high miR-590-3p was related with poor overall survival rate. Then, over-expressed miR-590-3p was demonstrated to promote proliferation, invasion and migration of colon caner cells. What's more, MST1, LATS1 and SAV1 mRNA were showed lowly expressed and YAP1 expression in mRNA and protein levels were highly expressed in CRC tissues, compared with adjacent normal tissues (all P<0.05). miR-590-3p expression was negatively associated with LATS1 and SAV1 mRNA respectively and positively related with YAP1 mRNA in CRC tissues, meanwhile, there was no relationship between miR-590-3p and MST1 mRNA. Furthermore, over-expressing miR-590-3p inhibited expressions of LATS1 and SAV1, promoted YAP1 expression and didn't effect MST1 expression in colon cancer cells. And luciferase assay showed that miR-590-3p over-expression inhibited the luciferase activity of LATS1 and SAV1 3'UTR, meanwhile it had no effect on the mutated form of these two plasmids. Taken together, these data suggest that highly-expressed miR-590-3p promotes biological effect of proliferation and metastasis via targeting Hippo pathway, and predicts worse clinical outcomes of CRC patients.
