| Research Abstract |
GOLPH3 was originally identified by proteomic analyses of Golgi proteins localized in the trans-Golgi network. Recently, it was reported that GOLPH3 is up-regulated in various types of malignancies. In order to explore the function of GOLPH3 and its isoform, GOLPH3L, in the pathogenesis of rhabdomyosarcoma, we investigated the expression and knockdown effects of GOLPH3/GOLPH3L in human rhabdomyosarcoma. Western blot analysis and real-time PCR revealed that human rhabdomyosarcoma cell lines and biopsy specimens exhibited an increased expression of GOLPH3/GOLPH3L. GOLPH3/GOLPH3L knockdown by siRNA prevented the proliferation of human rhabdomyosarcoma cell lines. In addition, double-knockdown of GOLPH3/GOLPH3L also prevented the proliferation of rhabdomyosarcoma cell lines. Our findings improve the understanding of rhabdomyosarcoma pathogenesis and suggest that the knockdown of GOLPH3/GOLPH3L may be an effective treatment for rhabdomyosarcoma.
