The Inhibitor of Growth 1 (ING1) gene has been identified and characterized as a Type-II tumor suppressor gene (TSG). Subsequently, 4 additional members of the family were identified by homology search. ING proteins contain a nuclear localization sequence (NLS) and a plant homeo domain (PHD) finger motif in their C-terminus. These proteins are involved in(More)
Senescence is a tumor suppression mechanism that is induced by several stimuli, including oncogenic signaling and telomere shortening, and controlled by the p53/p21(WAF1) signaling pathway. Recently, a critical role for secreted factors has emerged, suggesting that extracellular signals are necessary for the onset and maintenance of senescence. Conversely,(More)
Inhibitor of growth 4 (ING4) is a candidate tumor suppressor that plays a major role in gene regulation, cell cycle control, apoptosis, and angiogenesis. ING4 expression is down-regulated in glioblastoma cells and head and neck squamous cell carcinoma. Here, we identified liprin alpha1/PPFIA1, a cytoplasmic protein necessary for focal adhesion formation and(More)
ING2 (Inhibitor of Growth 2) is a candidate tumor suppressive protein frequently lost in human tumors. Recently, we have reported that ING2 downregulation impairs DNA replication forks progression and leads to genome instability. To better understand the tumor suppressive functions of ING2 and its role in the cell cycle, we downregulated its expression in(More)
ING2 (inhibitor of growth 2) is a candidate tumor-suppressor gene involved in cell cycle control, apoptosis and senescence. Although the functions of ING2 within the chromatin remodeling complex Sin3A/histone deacetylase (HDAC) and in the p53 pathway have been described, how ING2 itself is regulated remains unknown. In this study we report for the first(More)
ING2 is a candidate tumor suppressor gene involved in cell cycle control, apoptosis and senescence. Furthermore, we have recently shown that loss of ING2 expression is associated with increased genome instability. We investigated its status in a series of 120 non-small cell lung cancer (NSCLC) by using immunohistochemistry (IHC). The results showed that(More)
Inhibitor of growth 2 (ING2) is a candidate tumour suppressor gene the expression of which is frequently lost in tumours. Here, we identified a new function for ING2 in the control of DNA replication and in the maintenance of genome stability. Global replication rate was markedly reduced during normal S-phase in small interfering RNA (siRNA) ING2 cells, as(More)
OBJECTIVES Chloride intracellular channel protein 4 (Clic4) is a ubiquitously expressed protein involved in multiple cellular processes including cell-cycle control, cell differentiation, and apoptosis. Here, we investigated the role of Clic4 in pancreatic β-cell apoptosis. METHODS We used βTC-tet cells and islets from β-cell specific Clic4 knockout mice(More)
The contribution of lipid metabolic pathways to malignancy is poorly understood. Expression of the fatty acyl-CoA synthe-tase ACSVL3 was found to be markedly elevated in clinical malignant glioma specimens but nearly undetectable in normal glia. ACSVL3 levels correlated with the malignant behavior of human glioma cell lines and glioma cells propagated as(More)
Running title: Regulation of cell motility by ING4 and liprin α1Abstract ING4 is a candidate tumor suppressor that plays a major role in gene regulation, cell cycle control, apoptosis, and angiogenesis. ING4 expression is downregulated in glioblastoma cells, and head and neck squamous cell carcinoma. Here, we identified liprin α1/PPFIA1, a cytoplasmic(More)
