...in the 22 092 cells, PTEN was not expressed and AKT phosphorylation was elevated (Figure (Figure4A).4A)...Accordingly, PD184352 and MK2206 synergised to inhibit the growth of 22 092 cells in long-term proliferation assays (Figure (Figure4D),4D), and when the cells were grown in suspension (Figure (Figure44E).
