A network of substrates of the E3 ubiquitin ligases MDM2 and HUWE1 control apoptosis independently of p53.
(Sci Signal, 2013-05-07)In the intrinsic pathway of apoptosis, cell-damaging signals promote the release of cytochrome c from mitochondria, triggering activation of the Apaf-1 and caspase-9 apoptosome. The ubiquitin E3 ligase MDM2 decreases the ... -
Association between the ERCC5 Asp1104His polymorphism and cancer risk: a meta-analysis.
(PloS one, 2012-01)BACKGROUND: Excision repair cross complementing group 5 (ERCC5 or XPG) plays an important role in regulating DNA excision repair, removal of bulky lesions caused by environmental chemicals or UV light. Mutations in this ... -
Association of combined p73 and p53 genetic variants with tumor HPV16-positive oropharyngeal cancer.
(PloS one, 2012-01)p53 and p73 interact with human papillomavirus (HPV) E6 and E7 oncoproteins. The interplay between p53 and p73 and HPV16 may lead to deregulation of cell cycle and apoptosis, through which inflammation/immune responses control ... -
beta-arrestin-1 competitively inhibits insulin-induced ubiquitination and degradation of insulin receptor substrate 1.
(Mol Cell Biol, 2004-10)beta-arrestin-1 is an adaptor protein that mediates agonist-dependent internalization and desensitization of G-protein-coupled receptors (GPCRs) and also participates in the process of heterologous desensitization between ... -
Control of cyclin B1 localization through regulated binding of the nuclear export factor CRM1.
(Genes Dev, 1998-07-15)Activation of the Cyclin B/Cdc2 kinase complex triggers entry into mitosis in all eukaryotic cells. Cyclin B1 localization changes dramatically during the cell cycle, precipitously transiting from the cytoplasm to the nucleus ... -
Evaluation of an epithelial plasticity biomarker panel in men with localized prostate cancer.
(Prostate Cancer Prostatic Dis, 2016-03)BACKGROUND: Given the potential importance of epithelial plasticity (EP) to cancer metastasis, we sought to investigate biomarkers related to EP in men with localized prostate cancer (PC) for the association with time to ... -
Frequent ATRX, CIC, FUBP1 and IDH1 mutations refine the classification of malignant gliomas.
(Oncotarget, 2012-07)Mutations in the critical chromatin modifier ATRX and mutations in CIC and FUBP1, which are potent regulators of cell growth, have been discovered in specific subtypes of gliomas, the most common type of primary malignant ... -
Functional Variants in Notch Pathway Genes NCOR2, NCSTN, and MAML2 Predict Survival of Patients with Cutaneous Melanoma.
(Cancer Epidemiol Biomarkers Prev, 2015-07)BACKGROUND: The Notch signaling pathway is constitutively activated in human cutaneous melanoma to promote growth and aggressive metastatic potential of primary melanoma cells. Therefore, genetic variants in Notch pathway ... -
Genetic variants of GADD45A, GADD45B and MAPK14 predict platinum-based chemotherapy-induced toxicities in Chinese patients with non-small cell lung cancer.
(Oncotarget, 2016-05)The JNK and P38α pathways play a crucial role in tissue homeostasis, apoptosis and autophagy under genotoxic stresses, but it is unclear whether single nucleotide polymorphisms (SNPs) of genes in these pathways play a role ... -
How the kinetochore couples microtubule force and centromere stretch to move chromosomes.
(Nature cell biology, 2016-04)The Ndc80 complex (Ndc80, Nuf2, Spc24 and Spc25) is a highly conserved kinetochore protein essential for end-on anchorage to spindle microtubule plus ends and for force generation coupled to plus-end polymerization ... -
Huntingtin is required for normal excitatory synapse development in cortical and striatal circuits.
(J Neurosci, 2014-07-09)Huntington's disease (HD) is a neurodegenerative disease caused by the expansion of a poly-glutamine (poly-Q) stretch in the huntingtin (Htt) protein. Gain-of-function effects of mutant Htt have been extensively investigated ... -
Inhibition of the anaphase-promoting complex by the Xnf7 ubiquitin ligase.
(J Cell Biol, 2005-04-11)Degradation of specific protein substrates by the anaphase-promoting complex/cyclosome (APC) is critical for mitotic exit. We have identified the protein Xenopus nuclear factor 7 (Xnf7) as a novel APC inhibitor able to regulate ... -
Mouse double minute 4 variants modify susceptibility to risk of recurrence in patients with squamous cell carcinoma of the oropharynx.
(Molecular carcinogenesis, 2018-03)Given the crucial role of Mouse double minute 4 (MDM4) oncoprotein in p53 pathway, single nucleotide polymorphisms (SNPs) could serve as such biomarkers for prediction of SCCOP recurrence. Thus, we investigated associations ... -
Nuclear import of Cdk/cyclin complexes: identification of distinct mechanisms for import of Cdk2/cyclin E and Cdc2/cyclin B1.
(J Cell Biol, 1999-01-25)Reversible phosphorylation of nuclear proteins is required for both DNA replication and entry into mitosis. Consequently, most cyclin-dependent kinase (Cdk)/cyclin complexes are localized to the nucleus when active. Although ... -
Polymorphisms in the ERCC5 gene and risk of esophageal squamous cell carcinoma (ESCC) in Eastern Chinese populations.
(PloS one, 2012-01)BACKGROUND: Excision repair cross complementing group 5 (ERCC5 or XPG) plays an important role in regulating DNA excision repair; its functional single nucleotide polymorphisms (SNPs) may alter DNA repair capacity and thus ... -
Polymorphisms of nucleotide excision repair genes predict melanoma survival.
(The Journal of investigative dermatology, 2013-07)Melanoma is the most highly malignant skin cancer, and nucleotide excision repair (NER) is involved in melanoma susceptibility. In this analysis of 1,042 melanoma patients, we evaluated whether genetic variants of NER genes ... -
Sequence variations in DNA repair gene XPC is associated with lung cancer risk in a Chinese population: a case-control study.
(BMC cancer, 2007-01)BACKGROUND: The nucleotide excision repair (NER) protein, xeroderma pigmentosum C (XPC), participates in recognizing DNA lesions and initiating DNA repair in response to DNA damage. Because mutations in XPC cause a high ... -
Suppression of DNA-damage checkpoint signaling by Rsk-mediated phosphorylation of Mre11.
(Proc Natl Acad Sci U S A, 2013-12-17)Ataxia telangiectasia mutant (ATM) is an S/T-Q-directed kinase that is critical for the cellular response to double-stranded breaks (DSBs) in DNA. Following DNA damage, ATM is activated and recruited by the MRN protein complex ... -
