Original Article



Aberrant expression of miRNAs is crucial in several tissues tumorigenesis including thyroid. Recent studies demonstrated that miR-650 plays different role depending on the cancer type. Herein, we investigated the role of miR-650 in thyroid carcinoma.


The expression of miR-650 was analyzed in human thyroid tissues by q-RT-PCR. Anaplastic (8505C, CAL62, SW1736) and papillary (TPC-1) thyroid cancer cell lines were used to dissect the role of miR-650 on malignant hallmarks of transformation. Label-free proteomic analysis was exploited to unravel the targets of miR-650, while luciferase reporter assay and functional experiments were performed to confirm a selected target. Spearman’s rank correlation test was used to assess the association between miR-650 and its target in human thyroid cancer tissues.


miR-650 is over-expressed in anaplastic (ATC) thyroid carcinoma where it enhances cell migration and invasion. Proteomic label-free and bioinformatics analysis revealed that the serine-threonine protein phosphatase 2 catalytic subunit alpha (PPP2CA) is a target of miR-650; these finding were confirmed by luciferase assay. Restoration of PPP2CA mRNA, deprived of its 3′UTR, is able to revert the malignant phenotype induced by miR-650 in HEK-293 cells. Importantly, PPP2CA is down-regulated in ATC tissues and is inversely correlated with miR-650.


miR-650 displayed oncogenic activity in ATC cells through targeting PPP2CA phosphatase. These results suggest that miR-650/PPP2CA axis could be modulated to interfere with motile ability of thyroid carcinoma cells.
