title: [Effect of RII on the biological properties of human nasopharyngeal carcinoma cell lines].
abstract: N(4-hydroxycarbophenyl) retinamide (RII) is a new synthetic analog of retinoids with low toxicity. Its effect on the biological properties associated with tumor malignant behavior of human nasopharyngeal carcinoma cell lines (HNCs), including CNE-2Z parent cell lines and their variants L2, H2, L4 was studied. RII (10(-5) mol/L) caused detectable morphologic differentiation of HNCs. It inhibited growth of HNCs in vitro and decreased ability of these cells to penetrate matrigel-coated filters by using a reconstituted basement membrane invasion assay. These results suggested that RII might be a kind of useful anticancer drug.
