...we evaluated merlin protein expression in different human ovarian carcinoma cell lines...merlin level was...lowest in cells where PF-271 prevented anchorage-independent cell growth (HEY and OVCAR8)...A dramatic reduction in the number of HEY and OVCAR8 cells was observed at 0.1 μM PF-271 after 72 h (Fig. 1A, p<0.001)...These results show that HEY and OVCAR8 cells are highly sensitive to PF-271-mediated growth inhibition...
