    Skp2 targeting suppresses tumorigenesis by Arf-p53-independent cellular senescence (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-03-20
    Description: Cellular senescence has been recently shown to have an important role in opposing tumour initiation and promotion. Senescence induced by oncogenes or by loss of tumour suppressor genes is thought to critically depend on induction of the p19(Arf)-p53 pathway. The Skp2 E3-ubiquitin ligase can act as a proto-oncogene and its aberrant overexpression is frequently observed in human cancers. Here we show that although Skp2 inactivation on its own does not induce cellular senescence, aberrant proto-oncogenic signals as well as inactivation of tumour suppressor genes do trigger a potent, tumour-suppressive senescence response in mice and cells devoid of Skp2. Notably, Skp2 inactivation and oncogenic-stress-driven senescence neither elicit activation of the p19(Arf)-p53 pathway nor DNA damage, but instead depend on Atf4, p27 and p21. We further demonstrate that genetic Skp2 inactivation evokes cellular senescence even in oncogenic conditions in which the p19(Arf)-p53 response is impaired, whereas a Skp2-SCF complex inhibitor can trigger cellular senescence in p53/Pten-deficient cells and tumour regression in preclinical studies. Our findings therefore provide proof-of-principle evidence that pharmacological inhibition of Skp2 may represent a general approach for cancer prevention and therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2928066/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2928066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Hui-Kuan -- Chen, Zhenbang -- Wang, Guocan -- Nardella, Caterina -- Lee, Szu-Wei -- Chan, Chia-Hsin -- Yang, Wei-Lei -- Wang, Jing -- Egia, Ainara -- Nakayama, Keiichi I -- Cordon-Cardo, Carlos -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- R01 CA082328/CA/NCI NIH HHS/ -- R01 CA082328-13/CA/NCI NIH HHS/ -- R01 MD004038/MD/NIMHD NIH HHS/ -- England -- Nature. 2010 Mar 18;464(7287):374-9. doi: 10.1038/nature08815.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Biology and Genetics Program, Sloan-Kettering Institute, Memorial Sloan-Kettering Cancer Center, 1275 York Avenue, New York, New York 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20237562" target="_blank"〉PubMed〈/a〉

    The E3 ligase TRAF6 regulates Akt ubiquitination and activation (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-08-29
    Description: Akt signaling plays a central role in many biological functions, such as cell proliferation and apoptosis. Because Akt (also known as protein kinase B) resides primarily in the cytosol, it is not known how these signaling molecules are recruited to the plasma membrane and subsequently activated by growth factor stimuli. We found that the protein kinase Akt undergoes lysine-63 chain ubiquitination, which is important for Akt membrane localization and phosphorylation. TRAF6 was found to be a direct E3 ligase for Akt and was essential for Akt ubiquitination, membrane recruitment, and phosphorylation upon growth-factor stimulation. The human cancer-associated Akt mutant displayed an increase in Akt ubiquitination, in turn contributing to the enhancement of Akt membrane localization and phosphorylation. Thus, Akt ubiquitination is an important step for oncogenic Akt activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008763/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008763/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Wei-Lei -- Wang, Jing -- Chan, Chia-Hsin -- Lee, Szu-Wei -- Campos, Alejandro D -- Lamothe, Betty -- Hur, Lana -- Grabiner, Brian C -- Lin, Xin -- Darnay, Bryant G -- Lin, Hui-Kuan -- R01 CA149321/CA/NCI NIH HHS/ -- R01 CA149321-02/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 28;325(5944):1134-8. doi: 10.1126/science.1175065.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Oncology, The University of Texas M.

    PML regulates apoptosis at endoplasmic reticulum by modulating calcium release (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-30
    Description: The promyelocytic leukemia (PML) tumor suppressor is a pleiotropic modulator of apoptosis. However, the molecular basis for such a diverse proapoptotic role is currently unknown. We show that extranuclear Pml was specifically enriched at the endoplasmic reticulum (ER) and at the mitochondria-associated membranes, signaling domains involved in ER-to-mitochondria calcium ion (Ca(2+)) transport and in induction of apoptosis. We found Pml in complexes of large molecular size with the inositol 1,4,5-trisphosphate receptor (IP(3)R), protein kinase Akt, and protein phosphatase 2a (PP2a). Pml was essential for Akt- and PP2a-dependent modulation of IP(3)R phosphorylation and in turn for IP(3)R-mediated Ca(2+) release from ER. Our findings provide a mechanistic explanation for the pleiotropic role of Pml in apoptosis and identify a pharmacological target for the modulation of Ca(2+) signals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3017677/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3017677/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giorgi, Carlotta -- Ito, Keisuke -- Lin, Hui-Kuan -- Santangelo, Clara -- Wieckowski, Mariusz R -- Lebiedzinska, Magdalena -- Bononi, Angela -- Bonora, Massimo -- Duszynski, Jerzy -- Bernardi, Rosa -- Rizzuto, Rosario -- Tacchetti, Carlo -- Pinton, Paolo -- Pandolfi, Pier Paolo -- GGP05284/Telethon/Italy -- K99 CA139009/CA/NCI NIH HHS/ -- K99 CA139009-01A1/CA/NCI NIH HHS/ -- K99 CA139009-02/CA/NCI NIH HHS/ -- R01 CA071692/CA/NCI NIH HHS/ -- R01 CA071692-04S1/CA/NCI NIH HHS/ -- R01 CA102142/CA/NCI NIH HHS/ -- R01 CA102142-07/CA/NCI NIH HHS/ -- R01 CA142874/CA/NCI NIH HHS/ -- R01 CA142874-01/CA/NCI NIH HHS/ -- R01 CA142874-02/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Nov 26;330(6008):1247-51. doi: 10.1126/science.1189157.
