Abstract:
AIM:To study the action of nucleoside diphosphate kinase A(NDPK-A)on the growth of S_ 180,H_ 22,Lewis and H460.METHODS:S_ 180 or H_ 22 cell(5?106)were inoculate subcutaneously into the right armpit of 85 Kunming mice,which were randomized into 8 groups.Lewis lung carcinoma cells(2?105)were inoculate subcutaneously into the right armpit of 85 C57BL/6 mice,which were randomized as Kunming mice.From the 2nd day,the treated groups were given different dose of rhNDPK-A once a day for 8 days(for S_ 180 or H_ 22 by iv)or for 10 days(for Lewis by ip),and the control group was given physiological saline only.H460 tissue pieces about 1.5 mm?1.5 mm?1.5 mm each were inoculated subcutaneously into the armpit of 38 Balb/c/neu mice.After the volume of xenograft become 100 mm?100 mm?100 mm,the nude mice were randomized into 5 groups and given different dose of rhNDPK-A once a day for 17 days.2 days after above treatments,the mice were killed and dissected.The knubs were peeled off and weighted.RESULTS:The growth of S_ 180,H_ 22 and H460 were inhibited by rhNDPK and the growth of H_ 22 was inhibited by rhNDPK at dose of 20 mg/kg combined with cisplatin(0.5 mg/kg).But the growth of Lewis lung cancer was not inhibited.CONCLUSION:rhNDPK-A inhibited the growth of S_ 180,H_ 22 and H460.rhNDPK-A(20 mg/kg)potentiated the antitumor action of cisplatin on H_ 22.
