Web3 mrt. 2024 · Background. Medulloblastoma (MB) is the most common malignant pediatric brain tumor, and can be stratified into four major subgroups 1,2.One of these subgroups, Group 3, is often characterized by MYC amplification and arises in the presence of a functional ARF/p53 suppressor pathway 3.Group 3 tumors are considered very high risk … Web8 sep. 2004 · ARF effectively blocked the induction of c-Myc target genes and colocalizes with c-Myc in the nucleoplasm, so we wanted to determine whether ARF protein …

WebCDKN2A loss and p53 mutations are rare in MYC-driven Group 3 medulloblastomas (MBs). Here the authors generated a transgenic mouse model of Group 3 MB by MYC overexpression and show that MYC suppresses ARF to drive tumorigenesis.

WebThe Arf-Mdm2-p53 tumor suppressor pathway is activated by sustained hyperproliferative signals emanating from oncoproteins such as Myc. A recent study reveals a novel level of feedback control, whereby induced p19 Arf binds to Myc and blocks cell proliferation by selectively impairing its transactivation functions. Main text Web3 okt. 2012 · Oncogene activation such as that of c-Myc induces the stabilization of ARF by impairing the binding of ULF to ARF (Chen et al., 2010). Thus transcription-independent mechanisms are critically involved in ARF regulation during response to oncogenic stress. Here we report that the N-Myc and STATs interactor (NMI) is a novel ARF-interacting …
Web10 jan. 2003 · Western blot analyses of cells induced to express CTCF-sense message showed efficient induction of CTCF along with increased levels of ARF, a finding consistent with the demonstration of ARF as a … ARF expression is regulated by oncogenic signaling. Aberrant mitogenic stimulation, such as by MYC or Ras (protein), will increase its expression, as will an amplification of mutated p53 or Mdm2, or p53 loss. ARF can also be induced by enforced E2F expression. Although E2F expression is … Meer weergeven p14ARF (also called ARF tumor suppressor, ARF, p14 ) is an alternate reading frame protein product of the CDKN2A locus (i.e. INK4a/ARF locus). p14ARF is induced in response to elevated Meer weergeven Until recently, the two known effects of ARF were growth inhibition by NPM interactions and apoptosis induction by Mdm2 interactions.
