We studi ed the difTerential elTect of vitamins A, C, U. and E on normal human 이 al keratinocyte(NHOK) , HPV-16 E6E7 immor talized human oral keratinocyte(1HOK) , Oncogene transfected HPV-16 immortalized ce1ls(OTOK) , and two ol'al sq ua mous cell line(HNSCC30‘ HNSCC31) according to carcinogenesis stage. The vitamin effect was evaluated by morphology. ce ll viabi lity. a nd orgnaotypic culture Vitamin A has a greater negative effect on growth for all NHOK IHOK HNSCC. es pec ially N-Ras t rans fected IHOK, Vitamin D & E revealed no significant cell activity on NHOK lHOK, ad OTOK Vitamin C was found increased cell viability to IHOK and OTOK 1n primary oral squmaous cell ca rcino ma (HN30 ). vitam in 0 and C showing increased cell growth , but vitamin E showing no effect 1n metastatic oral squamous cell ca rcinoma(HN31), vitamin C has prol iferative effect , but vitamin 0 & E has anti-proliferative effect Vitamin A t reated normal a nd ma lignant ce1ls by organotypic cu lt ure. showed reduction of epithelial layer and in vasion to connective tissue. , especia lly in 1HOK & oncogene-transfected 1HOK, 1n conclusion. three-dimensional culture sys tem may be useful as a model to acess the efficiency of agents such as a1l trans retinoic acid can preventing progression of these premaligant lesion to maligant oral carcinoma(ch emopreventive agent) .
