D6R inhibits anchorage-independent growth in SW1990 and PaTu8988 cells. A colony-forming assay revealed a significantly lower number of colonies formed in D6R treated cells compared with untreated cells for the two cell lines, revealing that D6R inhibited SW1990 and PaTu8988 cell anchorage-independent growth. *P<0.05 vs. the D6R-free group. D6R, hexa-D-arginine.
