Fig. 7: The circ-HMGA2/miR-1236-3p/ZEB1/EMT axis regulates LUAD cell metastasis.

Circ-HMGA2 is highly expressed in lung adenocarcinoma and acts as a sponge of miR-1236-3P to promote the expression of ZEB1. ZEB1 acts as a transcription factor of EMT, promoting the progression of EMT and the metastasis of lung adenocarcinoma.
