Abstract/OtherAbstract:
Enhanced expression of valosin-containing protein (VCP) correlates with invasion and metastasis of cancers. To clarify the transcription mechanism of VCP, human and mouse genomic sequence was compared, revealing a 260 bp DNA sequence in the 5'-flanking region of VCP gene to be highly conserved between the two, in which binding motif of E74-like factor 2/new Ets-related factor (ELF2/NERF) was identified. Chromatin immunoprecipitation assay showed binding of ELF2/NERF to the 5'-flanking region of VCP gene. Knock-down of ELF2/NERF by siRNA decreased expression level of VCP. Viability of cells under tumor necrosis factor-alpha treatment significantly reduced in ELF2/NERF-knock-down breast cancer cell line. Immunohistochemical analysis on clinical breast cancer specimens showed a correlation of nuclear ELF2/NERF expression with VCP expression and proliferative activity of cells shown by Ki-67 immunohistochemistry. These findings indicate that ELF2/NERF promotes VCP transcription and that ELF2/NERF-VCP pathway might be important for cell survival and proliferation under cytokine stress.
