Effect of Retinoic Acid on the Growth of Subcutaneously Injected C1300 Neuroblastoma and on the Survival of the Host A / J Mice
Hee Boong Park, Byeong Jun, Seung Hoon Choi
Deficiency of vitamin A and/or its precursors has been associated with increased cancer risk in animals and humans. Therapeutic trials of vitamin A and related compounds(retinoids) have demonstrated activities in several cancerous and precancerous conditions. We measured the effects of a retinoic acid on the growth of subcutaneously injected C1300 neuroblastoma and on the survival of the host A/J mice. The fifty A/J mice were inoculated with 10' of C- 1300 neuroblastoma cell in the right back. They were divided into five groups. One group received saline as a control. Two groups recieved 2 mg/kg and 5 mg/kg of retinoic acid. The other two groups recieved low dose(50 mg/kg and 100 mg/kg) cysclophosphamide. Tumor volume and survival were assessed. The survivals were significantly increased(p<0.05) in three groups, mice recieved 5 mg/kg of retinoic acid, 50 mg/kg and 100 mg/kg of cyclophosphamide. Tumor volumes of the mice treated with 5 mg/kg of retinoic acid were significantly lower than the control group(p<0.05). Retinoic acid suppressed the growth of neuroblastoma, it increased the survival of the treated mice if adequate doses were used.
Key words: Retinoic acid, Neuroblastoma and cyclophosphamide
