It has reported that microRNAs such as miR-103/10753, long non-coding RNAs such as lncRNA DUXAP854, circular RNAs such as circ-ITCH55, anti-tumor drugs such as β-elemene56, and signaling pathways such as NF-κB57 are able to target PTEN in BCa cells, effecting the cell survival, proliferation, migration, invasion, apoptosis and chemoresistance of BCa. Here, PTEN is linked to neoplasm.
