Abstract

Endometrial carcinoma (EC) is one of the most common gynecologic malignancy, but molecular mechanisms of the development and progression of EC remain unclear. Here we showed that the expression of DICER1 was negatively associated with the level of histone methylation, histone acetylation and PRC2 components SUZ12 and EZH2 in EC cells. In addition, knockdown of DICER1 significantly downregulated miR-200b and let-7i, which may then regulate their targets SUZ12 and EZH2. Furthermore, knockdown of DICER1 remarkably suppressed the expression of epithelial cell marker E-cadherin, induced the expression of mesenchymal cell marker Vimentin, and promoted the invasion of EC cells. In conclusion, our data suggest that DICER1 suppresses SUZ12 and EZH2 via affecting their upstream miRNA synthesis, and inhibits epithelial-mesenchymal transition(EMT) and invasion of EC cells via histone modification.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
