Human gastric cancer SNU 484 cells express mutant p16, which migrates slower than the wild-type p16. We constructed an expression vector containing human p16 cDNA to evaluate the cytotoxic effects of exogenous p16 expression on SNU 484 cell proliferation and to explore the potential use of p16 in cancer gene therapy. The stable transfectant expressing(More)
Neural crest cells constitute a multipotent cell population that gives rise to diverse cell lineages. The neural crest arising from the postotic hindbrain is known as the 'cardiac' neural crest, and contributes to the great vessels and outflow tract endocardial cushions, but the neural crest contribution to structures within the heart remains largely(More)
Most gnathostomata craniofacial structures derive from pharyngeal arches (PAs), which are colonized by cranial neural crest cells (CNCCs). The anteroposterior and dorsoventral identities of CNCCs are defined by the combinatorial expression of Hox and Dlx genes. The mechanisms associating characteristic Hox/Dlx expression patterns with the topology and(More)

Endothelin-1 (Edn1), originally identified as a vasoconstrictor peptide, is involved in the development of cranial/cardiac neural crest-derived tissues and organs. In craniofacial development, Edn1 binds to Endothelin type-A receptor (Ednra) to induce homeobox genes Dlx5/Dlx6 and determines the mandibular identity in the first pharyngeal arch. However, it(More)
Ceramide generated from sphingomyelin in response to ionizing radiation has been implicated as a second messenger to induce cellular proapoptotic signals. Both ceramide and its metabolic inhibitor, N, N-dimethyl-D-erythro-sphingosine (DMS), might lead to sustained ceramide accumulation in cells more efficiently, thereby sensitizing them to(More)
BACKGROUND In the 1990s the primary focus of medicine was shifted to disease prevention. Accordingly, it became the responsibility of primary-care physicians to educate and counsel the general population not only on disease prevention specifically but health promotion generally as well. Moreover, it was, and is still today, considered important that(More)
