Growth delay experiments performed on DB-1 human melanoma xenografts in nude mice treated with 7.5 mg/kg LPAM. Mice were treated on Day 0 as follows: Control (sham i.p. tris/glycine buffer + sham i.v. PBS), LND, LPAM, LND + LPAM. Values shown are means ± SEM for n = 4 animals, Control and LND groups; n = 3 animals, LPAM and LND + LPAM groups. When not shown, error bars are less than symbol size.
