Abstract:
miR-20a is an important member of the miR-17-92 cluster, and its real function in cervical cancer cells is unknown. Our study demonstrated that miR-20a was upregulated in cervical cancer tissues. Overexpression of miR-20a in cervical cancer-derived cell lines, HeLa and C-33A, enhanced long-term cellular proliferation, migration and invasion, whereas inhibition of miR-20a suppressed those functions. We also confirmed that oncogenic TNKS2 is directly upregulated by miR-20a. Furthermore, suppression of TNKS2 expression could inhibit colony formation, migration and invasion of cervical cancer cells. Therefore, we concluded that miR-20a can promote migration and invasion of cervical cancer cells through the upregulation of TNKS2.

Role of Myosin in Cell Migration
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
