| Detail Description: | Here, we provide evidence that miR-509-5p, which is downregulated in a subset of newly diagnosed cervical cancer and hepatocellular carcinoma tissues compared with the adjacent nontumor tissue, can be activated by p53 through binding the promoter of miR-509-5p and it suppresses the growth and invasion/migration of cervical cancer and hepatoma cells by regulating apoptosis and the G1/S-phase transition of cell cycle. Furthermore, Mdm2 was identified to be a target of miR-509-5p by targeting its 3'-UTR. Restoration of Mdm2 abrogated the cell phenotypes induced by miR-509-5p. Moreover, ectopic expression of miR-509-5p in HeLa and QGY-7703 cells repressed the expression of Mdm2, subsequently enhancing its p53-activating effects. These results suggest that miR-509-5p is a new regulator of Mdm2/p53 pathway and may play a key role in cancer development. |
The 'First Node' or 'Second Node' option represents the sub-network of interacting entry with the first or second interaction node,
the 'Both the Nodes' option represents the sub-network of interacting entry with both of interaction nodes.
The 'First Neighbour' represents the sub-network of direct interacting with the center node,
the 'Second Neighbour' represents the sub-network of direct or second step interacting with the center node.
Interaction sub-network based on the two nodes of this interaction may help the researchers represents all interacting partners immediately.
