title: [Functional genomics of nasopharyngeal carcinoma susceptibility/suppressor gene].
abstract: There is obvious allele disequilibrium in nasopharyngeal carcinoma at chromosome 3p, 9p, 6q, 11q, 13q and 14q. Nasopharyngeal carcinoma (NPC) susceptibility/suppressor gene candidates were obtained by molecular biology methods,such as cDNA representational difference ana-lysis. The functional research of NPC susceptibility/ suppressor gene candidates indicated: (1) The increased expression of Cx contributed to obstacles of gap junctional intercellular communication (GJIC), and resulted an aberration of GJIC; (2) BRD7, a transcript factor, was associated with cell cycle regulation; (3) NAG7,an estrogen receptor repressor, inhibited the invasive potential of human NPC cells by regulating ERalpha expression and the H-ras/p-c-Raf and JNK/AP-1/MMP1 signaling pathways; (4) NGX6, a metastasis-associated protein, can negative-regulate EGF/Ras/MAPK signaling transduction pathway, and interact with ezrin protein to inhibit invasion and metastasis of NPC cells; (5) SPLUNC1, a secreted protein, can inhibit the bacterium clone formation, and is an innate immune molecule. These data will lay an important foundation for the NPC mechanism.
