Zinc finger transcription factors are involved broadly in development and tumorigenesis. Here, we report that the little studied zinc finger transcription factor ZNF382 functions as a tumor suppressor in multiple carcinomas. Although broadly expressed in normal tissues, ZNF382 expression was attenuated in multiple carcinoma cell lines due to promoter CpG(More)
Epigenetic disruption of tumor suppressor genes is frequently involved in tumorigenesis. We identified a novel 19q13 KRAB domain-containing zinc finger protein, ZNF545/ZFP82, broadly expressed in normal tissues but downregulated in multiple tumor cell lines. The ZNF545 promoter contains a CpG island, which is frequently methylated in cell lines. The(More)
Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus-associated tumor prevalent in southern China and southeast Asia, with the 3p14-p12 locus reported as a critical tumor suppressor gene (TSG) region during its pathogenesis. We identified a novel 3p14.2 TSG, FEZF2 (FEZ family zinc finger 2), for NPC. FEZF2 is readily expressed in normal tissues including(More)
UNLABELLED Loss of 16q is one of the most frequent alterations in many malignancies including hepatocellular carcinomas (HCC), suggesting the existence of a tumor suppressor gene (TSG) within the frequently deleted region. In this report we describe the identification and characterization of one candidate TSG, tyrosine aminotransferase gene (TAT), at(More)
Acylglycerol kinase (AGK) regulates various cellular processes involved into tumorigenesis and tumor progression. To investigate involvement of AGK in human gliomas, here, quantitative real-time polymerase chain reaction, Western blot, and immunohistochemistry analyses were performed to respectively detect the expression of AGK mRNA and protein in glioma(More)
OBJECTIVE Zinc-finger protein 545 (ZNF545) is a member of the family of Krüppel-associated box-containing zinc-finger proteins. The aim of this study was to clarify its biological function as a tumour suppressor in gastric cancer. DESIGN The biological function of ZNF545 was determined by cell growth and apoptosis assays. The ZNF545 target signal pathway(More)
Src homology 3 (SH3) domains mediate intracellular protein-protein interactions through the recognition of proline-rich sequence motifs on cellular proteins. Such protein-protein interactions can activate the protein kinase cascade that mediates MAPK signaling pathway. The human hole gene, hhole, is a 319-amino acid six-transmembrane protein with(More)
Abnormal activation of Wnt/β-catenin-mediated transcription is associated with a variety of human cancers. Here, we report that LATS2 inhibits oncogenic Wnt/β-catenin-mediated transcription by disrupting the β-catenin/BCL9 interaction. LATS2 directly interacts with β-catenin and is present on Wnt target gene promoters. Mechanistically, LATS2 inhibits the(More)
The zinc finger proteins are the single largest class of transcription factors in human genome. Previous studies revealed that zinc finger proteins are involved in transcriptional activation and regulation of apoptosis, etc. Alternative splicing emerges as a major mechanism of generating protein diversity and many zinc finger proteins reported have(More)
Human colorectal cancer stem cells (CSCs) are tumour initiating cells that can self-renew and are highly tumorigenic and chemoresistant. While genetic mutations associated with human colorectal cancer development are well-known, little is known about how and whether epigenetic factors specifically contribute to the functional properties of human colorectal(More)
