title: Retinoic acid receptor-beta mRNA expression during chemoprevention of hamster cheek pouch carcinogenesis by garlic.
abstract: The effect of aqueous garlic (Allium sativum Linn.) on retinoic acid receptor beta (RARbeta) mRNA expression was investigated in male Syrian hamsters during 12-dimethyl enz[a]anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis. RARbeta mRNA expression was analysed by slot blotted hybridization with radiolabelled RAR-beta probe. In DMBA-induced HBP tumours, decreased expression of RARbeta mRNA was observed. Administration of garlic (250mg/kg body weight) to animals painted with DMBA restored RARbeta mRNA expression to normal pattern suggesting that this may be one of the mechanisms by which garlic exerts its chemopreventive effects.
