New role for NG2/MPG in apoptosis and antitumour drug resistance
By activating a 3b1 integrin and downstream PI3k/Akt signaling pathway, NG2/MPG was found to promote tumor resistance to antitumour drugs such as doxorubicin, etoposide and carboplatin. Thus, NG2 should represent an effective therapeutic target in several cancer types.
