Ann Med 2023; 55:2278619. [PMID: 37939252 PMCID: PMC10653697 DOI: 10.1080/07853890.2023.2278619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 10/30/2023] [Indexed: 11/10/2023] Open
Abstract
BACKGROUND The treatment of Colorectal cancer (CRC) is extremely complex and survival rates vary depending on the stage of the disease at the time of diagnosis. Neoadjuvant chemoradiotherapy (NACRT), is the conventional treatment for locally advanced rectal cancer (LARC); however, the resistance to chemoradiotherapy in LARC is difficult to predict. MATERIALS AND METHODS In this study, clinical data of 126 LARC patients were collected and analyzed, and relevant validation was performed using GEO database and in vitro and in vivo experiments, including Western blotting and Real-time quantitative PCR, immunohistochemistry, immunofluorescence, clonogenic cell survival assays, and nude-mouse xenograft models. RESULTS In patients with LARC who were treated with neoadjuvant radiotherapy (NART), higher ZNF281 expression in malignant tissue was associated with a poorer prognosis and lesser degree of tumor regression. Cell and mouse experiments have shown that ZNF281 reduces the damage caused by X-rays to CRC cells and tumors grown in mice. CONCLUSION We found that the expression of ZNF281 predicted the radiation response of CRC cells and suggested the prognosis of patients with LARC who received neoadjuvant radiation therapy.

Cell Death Discov 2023; 9:396. [PMID: 37880213 PMCID: PMC10600106 DOI: 10.1038/s41420-023-01691-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 09/25/2023] [Accepted: 10/16/2023] [Indexed: 10/27/2023] Open
Abstract
Zinc finger protein 281 (ZNF281) has been shown to promote tumor progression. However, the underlying mechanism remains to be further elucidated. In this study, ZNF281 knockdown increased the expression of mitochondrial transcription factor A (TFAM) in hepatocellular carcinoma (HCC) cells, accompanied with increment of mitochondrial content, oxygen consumption rate (OCR) and levels of TCA cycle intermetabolites. Mechanistic investigation revealed that ZNF281 suppressed the transcription of TFAM, nuclear respiratory factor 1 (NRF1) and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α). Furthermore, ZNF281 interacted with NRF1 and PGC-1α, and was recruited onto the promoter regions of TFAM, TFB1M and TFB2M repressing their expression. Knockdown of TFAM reversed ZNF281 depletion induced up-regulation of mitochondrial biogenesis and function, as well as impaired epithelial mesenchymal transition, invasion and metastasis of HCC cells. Our research uncovered a novel suppressive function of ZNF281 on mitochondrial biogenesis through inhibition of the NRF1/PGC-1α-TFAM axis, which may hold therapeutic potentials for HCC.

Cell Death Differ 2023; 30:702-715. [PMID: 36220888 PMCID: PMC9984498 DOI: 10.1038/s41418-022-01073-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 09/28/2022] [Accepted: 09/29/2022] [Indexed: 03/05/2023] Open
Abstract
Although the Hedgehog (Hh) pathway plays an evolutionarily conserved role from Drosophila to mammals, some divergences also exist. Loss of Sufu, an important component of the Hh pathway, does not lead to an obvious developmental defect in Drosophila. However, in mammals, loss of SUFU results in serious disorder, even various cancers. This divergence suggests that SUFU plays additional roles in mammalian cells, besides regulating the Hh pathway. Here, we identify that the transcription factor ZNF281 is a novel binding partner of SUFU. Intriguingly, the Drosophila genome does not encode any homologs of ZNF281. SUFU is able to suppress ZNF281-induced tumor cell migration and DNA damage repair by inhibiting ZNF281 activity. Mechanistically, SUFU binds ZNF281 to mask the nuclear localization signal of ZNF281, culminating in ZNF281 cytoplasmic retention. In addition, SUFU also hampers the interactions between ZNF281 and promoters of target genes. Finally, we show that SUFU is able to inhibit ZNF281-induced tumor cell migration using an in vivo model. Taken together, these results uncover a Hh-independent mechanism of SUFU exerting the anti-tumor role, in which SUFU suppresses tumor cell migration through antagonizing ZNF281. Therefore, this study provides a possible explanation for the functional divergence of SUFU in mammals and Drosophila.

Abstract
Objective To investigate the involvement and transcriptional targets of zinc finger protein 281 (ZNF281) in the progression of hepatocellular carcinoma (HCC). Methods The expression of ZNF281 in HCC was detected in tissue microarray and cell lines. The role of ZNF281 in aggressiveness of HCC was examined using wound healing, matrigel transwell, pulmonary metastasis model and assays for expression of EMT markers. RNA-seq was used to find potential target gene of ZNF281. Chromatin immunoprecipitation (ChIP) assay and co-immunoprecipitation (Co-IP) were employed to uncover the mechanism of the transcriptional regulation of ZNF281 on the target gene. Results ZNF281 was increased in tumor tissues and positively correlated with vascular invasion in HCC. Knockdown of ZNF281 suppressed the migration and invasion with significant alteration of EMT marker expression in HLE and Huh7 HCC cell lines. RNA-seq screening showed that the tumor suppressor gene Annexin A10 (ANXA10) was a most up-regulated gene in response to ZNF281 depletion and responsible for the attenuation of aggressiveness. Mechanistically, ZNF281 interacted with the ANXA10 promoter region harboring ZNF281 recognition sites, and recruited components of nucleosome remodeling and deacetylation (NuRD) complex. By knocking down such components like HDAC1 or MTA1, ANXA10 was released from transcriptional repression by ZNF281/NuRD, and in turn reversed the EMT, invasion and metastasis driven by ZNF281. Conclusion ZNF281 drives invasion and metastasis of HCC partially through transcriptional repression of tumor suppressor gene ANXA10 by recruiting NuRD complex.

Abstract
Crohn’s disease (CD) and ulcerative colitis (UC) are chronic inflammatory disorders of the gastrointestinal tract. Chronic inflammation is the main factor leading to intestinal fibrosis, resulting in recurrent stenosis, especially in CD patients. Currently, the underlying molecular mechanisms of fibrosis are still unclear. ZNF281 is a zinc-finger transcriptional regulator that has been characterized as an epithelial-to-mesenchymal transition (EMT)-inducing transcription factor, suggesting its involvement in the regulation of pluripotency, stemness, and cancer. The aim of this study is to investigate in vivo and in vitro the role of ZNF281 in intestinal fibrogenesis. Intestinal fibrosis was studied in vivo in C57BL/6J mice with chronic colitis induced by two or three cycles of administration of dextran sulfate sodium (DSS). The contribution of ZNF281 to gut fibrosis was studied in vitro in the human colon fibroblast cell line CCD-18Co, activated by the pro-fibrotic cytokine TGFβ1. ZNF281 was downregulated by siRNA transfection, and RNA-sequencing was performed to identify genes regulated by TGFβ1 in activated colon fibroblasts via ZNF281. Results showed a marked increase of ZNF281 in in vivo murine fibrotic colon as well as in in vitro human colon fibroblasts activated by TGFβ1. Moreover, abrogation of ZNF281 in TGFβ1-treated fibroblasts affected the expression of genes belonging to specific pathways linked to fibroblast activation and differentiation into myofibroblasts. We demonstrated that ZNF281 is a key regulator of colon fibroblast activation and myofibroblast differentiation upon fibrotic stimuli by transcriptionally controlling extracellular matrix (ECM) composition, remodeling, and cell contraction, highlighting a new role in the onset and progression of gut fibrosis.

Abstract
R-loops are prevalent in mammalian genomes and involved in many fundamental cellular processes. Depletion of BRCA2 leads to aberrant R-loop accumulation, contributing to genome instability. Here, we show that ZFP281 cooperates with BRCA2 in preventing R-loop accumulation to facilitate DNA replication in embryonic stem cells. ZFP281 depletion reduces PCNA levels on chromatin and impairs DNA replication. Mechanistically, we demonstrate that ZFP281 can interact with BRCA2, and that BRCA2 is enriched at G/C-rich promoters and requires both ZFP281 and PRC2 for its proper recruitment to the bivalent chromatin at the genome-wide scale. Furthermore, depletion of ZFP281 or BRCA2 leads to accumulation of R-loops over the bivalent regions, and compromises activation of the developmental genes by retinoic acid during stem cell differentiation. In summary, our results reveal that ZFP281 recruits BRCA2 to the bivalent chromatin regions to ensure proper progression of DNA replication through preventing persistent R-loops. R-loops are prevalent in mammalian genomes and involved in many fundamental cellular processes. Here, Wang et al. report that ZFP281 cooperates with BRCA2 in preventing R-loop accumulation to facilitate DNA replication in embryonic stem cells.

Abstract
Aberrant Wnt/β-catenin signaling is central to colorectal cancer carcinogenesis. The well-known potential of targeting the canonical Wnt signaling pathway for the treatment of CRC is largely attributed to the ability of this pathway to regulate various cellular processes such as cell proliferation, metastasis, drug resistance, immune response, apoptosis, and cellular metabolism. However, with the current approach of targeting this pathway, none of the Wnt-targeted agents have been successfully implicated in clinical practice. Instead of using classical approaches to target this pathway, there is a growing need to find new and modified approaches to achieve the same. For this, a better understanding of the regulation of β-catenin, a major effector of the canonical Wnt pathway is a must. The present review addresses the importance of understanding the regulation of β-catenin beyond the destruction complex. Few recently discovered β-catenin regulators such as ZNF281, TTPAL, AGR2, ARHGAP25, TREM2, and TIPE1 showed significant potential in regulating the development of CRC through modulation of the Wnt/β-catenin signaling pathway in both in vitro and in vivo studies. Although the expression and activity of β-catenin is influenced by many protein regulators, the abovementioned proteins not only influence its expression and activation but are also directly involved in the development of CRC and various other solid tumors. Therefore, we hypothesise that focusing the current research on finding the detailed mechanism of action of these regulators may assist in providing with a better treatment approach or improve the current therapeutic regimens.

Abstract
The expression of coinhibitory receptors, such as CTLA-4, on effector T cells is a key mechanism for the negative regulation of T-cell activation. However, the transcriptional regulation of CTLA-4 is not well understood. Zfp281, a C2H2 zinc finger protein, is a negative regulator of pluripotency maintenance of embryonic stem cells. Nevertheless, the function of Zfp281 in differentiated cells has not been studied. We generated Zfp281 conditional knockout mice in which the function of the Zfp281 gene was conditionally disrupted by the Cd4Cre transgene to study its impact on T cell function. Zfp281 had no effect on T-cell development, but CD4+ T cell activation and cytokine production were impaired due to diminished T-cell receptor signaling. Furthermore, Zfp281 deficiency inhibited in vivo T cell responses to Listeria monocytogenes infection. Using genome-wide expression profiling assays, we determined that Zfp281 repressed Ctla-4 expression by directly binding to GC-rich sites in its promoter, which inhibited the negative feedback of T cell activation. In line with this result, CTLA-4 blockade and shRNA knockdown partly rescued the reduced cytokine production caused by Zfp281 deficiency. These findings indicate that Zfp281 sustains CD4+ T lymphocyte activation by directly repressing Ctla-4 transcription.

Abstract
Breast cancer is the most common malignancy, and metastasis is the main cause of cancer-associated mortality in women worldwide. Transforming growth factor-β (TGF-β) signaling, an inducer of epithelial-to-mesenchymal transition (EMT), plays an important role in breast cancer metastasis. Abnormal expression of miR-543 is associated with tumorigenesis and progression of various human cancers; however, the knowledge about the role of miR-543 in breast cancer metastasis is still unknown. In this study, we demonstrated that miR-543 inhibits the EMT-like phenotype and TGF-β-induced breast cancer metastasis both in vitro and in vivo by targeting ZNF281. ZNF281 transactivates the EMT-related transcription factor ZEB1 and Snail. Furthermore, both ZEB1 and Snail can transcriptionally suppress miR-543 expression. Taken together, our data uncover the ZNF281-miR-543 feedback loop and provide a mechanism to extend the understanding of TGF-β network complexity.

Abstract
Erythroid maturation requires the concerted action of a core set of transcription factors. We previously identified the Krüppel-type zinc finger transcription factor Zfp148 (also called ZBP-89) as an interacting partner of the master erythroid transcription factor GATA1. Here we report the conditional knockout of Zfp148 in mice. Global loss of Zfp148 results in perinatal lethality from nonhematologic causes. Selective Zfp148 loss within the hematopoietic system results in a mild microcytic and hypochromic anemia, mildly impaired erythroid maturation, and delayed recovery from phenylhydrazine-induced hemolysis. Based on the mild erythroid phenotype of these mice compared with GATA1-deficient mice, we hypothesized that additional factor(s) may complement Zfp148 function during erythropoiesis. We show that Zfp281 (also called ZBP-99), another member of the Zfp148 transcription factor family, is highly expressed in murine and human erythroid cells. Zfp281 knockdown by itself results in partial erythroid defects. However, combined deficiency of Zfp148 and Zfp281 causes a marked erythroid maturation block. Zfp281 physically associates with GATA1, occupies many common chromatin sites with GATA1 and Zfp148, and regulates a common set of genes required for erythroid cell differentiation. These findings uncover a previously unknown role for Zfp281 in erythroid development and suggest that it functionally overlaps with that of Zfp148 during erythropoiesis.

Abstract
Background and aims: Recent evidences reveal the occurrence of a close relationship among epithelial to mesenchymal transition (EMT), chronic inflammation and fibrosis. ZNF281 is an EMT-inducing transcription factor (EMT-TF) involved in the regulation of pluripotency, stemness, and cancer. The aim of this study was to investigate in vitro, in vivo, and ex vivo a possible role of ZNF281 in the onset and progression of intestinal inflammation. A conceivable contribution of the protein to the development of intestinal fibrosis was also explored. Methods: Human colorectal adenocarcinoma cell line, HT29, and C57BL/6 mice were used for in vitro and in vivo studies. Mucosal biopsy specimens were taken during endoscopy from 29 pediatric patients with Crohn's disease (CD), 24 with ulcerative colitis (UC) and 16 controls. ZNF281 was knocked down by transfecting HT29 cells with 20 nM small interference RNA (siRNA) targeting ZNF281 (siZNF281). Results: We show for the first time that ZNF281 is induced upon treatment with inflammatory agents in HT29 cells, in cultured uninflamed colonic samples from CD patients and in DSS-treated mice. ZNF281 expression correlates with the disease severity degree of CD and UC patients. Silencing of ZNF281 strongly reduces both inflammatory (IL-8, IL-1beta, IL-17, IL-23) and EMT/fibrotic (SNAIL, Slug, TIMP-1, vimentin, fibronectin, and α-SMA) gene expression; besides, it abolishes the increase of extracellular-collagen level as well as the morphological modifications induced by inflammation. Conclusions: The identification of transcription factor ZNF281 as a novel player of intestinal inflammation and fibrosis allows a deeper comprehension of the pathogenetic mechanisms underlying inflammatory bowel disease (IBD) and provide a new target for their cure.

Abstract
In order to assess whether N-Myc downstream regulated gene 4 (NDRG4) methylation was associated with the diagnosis and prognosis of gastric cancer, we measured the methylation of NDRG4 promoter and gene body regions among 110 gastric cancer patients using quantitative methods (MethyLight and pyrosequencing). Both NDRG4 promoter and gene body methylation levels were increased in tumor tissues than paired adjacent normal tissues (P < 0.001). NDRG4 gene body methylation was found to be significantly associated with age and tumor differentiation. NDRG4 promoter hypermethylation was proved to be a predictor of poor overall survival. However, opposite result was observed among The Cancer Genome Atlas (TCGA) cohort. The findings from gastric cell lines and public databases have suggested that NDRG4 methylation level was inversely associated with NDRG4 transcription level. Subsequent luciferase reporter gene assay showed that promoter CpG island but not gene body CpG island was able to upregulate gene expression. Collectively, NDRG4 promoter hypermethylation contributed to the risk of gastric cancer and predicted a poor prognosis in Chinese gastric cancer patients. Moreover, the combined methylation levels of NDRG4 promoter and gene body served as diagnostic biomarkers in gastric cancer.

Nucleic Acids Res 2017; 45:1177-1185.

Abstract
Genomic imprinting is an epigenetic regulation that leads to gene expression in a parent-of-origin specific manner. AFF3, the central component of the Super Elongation Complex-like 3 (SEC-L3), is enriched at both the intergenic-differentially methylated region (IG-DMR) and the Meg3 enhancer within the imprinted Dlk1-Dio3 locus to regulate the allele-specific gene expression in this locus. The localization of AFF3 to IG-DMR requires ZFP57. However, how AFF3 functions at the Meg3 enhancer in maintaining allele-specific gene expression remains unclear. Here, we demonstrate that AFF3 is associated with the Krüppel-like zinc finger protein ZFP281 in mouse embryonic stem (ES) cells. ZFP281 recruits AFF3 to the Meg3 enhancer within the imprinted Dlk1-Dio3 locus, thus regulating the allele-specific expression of the Meg3 polycistron. Our genome-wide analyses further identify ZFP281 as a critical factor generally associating with AFF3 at enhancers and functioning together with AFF3 in regulating the expression of a subset of genes. Our study suggests that different zinc finger proteins can recruit AFF3 to different regulatory elements and differentially regulate the function of AFF3 in a context-dependent manner.

GSK-3β phosphorylation-dependent degradation of ZNF281 by β-TrCP2 suppresses colorectal cancer progression. Oncotarget 2017; 8:88599-88612.

Abstract
Zinc finger protein 281 (ZNF281) has been recently shown to be critical for CRC progression. However, the immediate upstream regulators of ZNF281 remain unclear. Here we reported that the E3 ligase the β-transducin repeat-containing protein 2 (β-TrCP2) governs the ubiquitination and degradation of ZNF281. In human CRC specimens, endogenous β-TrCP2 were inversely correlated with ZNF281. Beta-TrCP2 reversed the phenotype of CRC cell with overexpressed ZNF281. Moreover, we found that glycogen synthase kinase 3β (GSK-3β), not GSK-α, could bind to and phosphorylate ZNF281 at one consensus motif (TSGEHS; phosphorylation site is shown in italics), which promotes the interaction of ZNF281 with β-TrCP2, not β-TrCP1, and leads to the subsequent ubiquitination and degradation of phosphorylated ZNF281. A mutant of ZNF281 (ZNF281-S638A) is much more stable than wild-type ZNF281 because ZNF281-S638A mutant abolishes the phosphorylation by GSK-3β and can not be ubiquitinated and degraded by β-TrCP2. Conversely, ZNF281 transcriptionally repressed the expression of β-TrCP2, indicating a negative feedback loop between ZNF281 and β-TrCP2 in CRC cells. These findings suggest that the turnover of ZNF281 by β-TrCP2 might provide a potentially novel treatment for patients with CRC.

Abstract
BACKGROUND Zinc finger protein 281 (ZNF281) has been identified to be involved in embryonic stem cell differentiation and tissue development. Also, ZNF281 was found in various types of cancers. However, its biological functions and clinical significance in pancreatic cancer remain elusive. AIMS To explore the role of ZNF281 in pancreatic cancer cells proliferation and invasion. METHODS ZNF281 expression was examined in public database Oncomine and cBioPortal. The correlation between ZNF281 and clinicopathological features was measured, and Kaplan-Meier method was used to measure the overall survival and recurrence-free survival in the TCGA cohort. Ectopic expression and knockdown of ZNF281 were performed to measure the impact on cell proliferation and invasion. Western blot and immunoprecipitation were further used to identify the ZNF281 interacting proteins. Topflash luciferase assay was used to detect the Wnt/β-catenin signaling activation. RESULTS ZNF281 was predominantly up-regulated in pancreatic cancer tissues and significantly associated with advanced stage. Meanwhile, the high expression of ZNF281 indicated shorter overall survival and recurrence-free survival and ZNF281 could be an independent prognostic factor of pancreatic cancer. ZNF281 promoted cell proliferation and invasion in vitro. Mechanically, ZNF281 activated Wnt/β-catenin signaling and induced the downstream gene expression by directly binding with β-catenin and decreasing the polyubiquitination. CONCLUSIONS ZNF281 promotes pancreatic cancer cells proliferation and invasion by interacting and up-regulating β-catenin, highlighting the role of ZNF281 in pancreatic cancer progression.

Abstract
Epithelial-mesenchymal transition (EMT) represents an important mechanism during development and wound healing, and its deregulation has been implicated in metastasis. Recently, the Krüppel-type zinc-finger transcription factor ZNF281 has been characterized as an EMT-inducing transcription factor (EMT-TF). Expression of ZNF281 is induced by the EMT-TF SNAIL and inhibited by the tumor suppressive microRNA miR-34a, which mediates repression of ZNF281 by the p53 tumor suppressor. Therefore, SNAIL, miR-34a and ZNF281 form a feed-forward regulatory loop, which controls EMT. Deregulation of this circuitry by mutational and epigenetic alterations in the p53/miR-34a axis promotes colorectal cancer (CRC) progression and metastasis formation. As ZNF281 physically interacts with the transcription factors NANOG, OCT4, SOX2, and c-MYC, it has been implicated in the regulation of pluripotency, stemness, and cancer. Accordingly, ectopic ZNF281 expression in CRC lines induces the stemness markers LGR5 and CD133 and promotes sphere formation, suggesting that the elevated expression of ZNF281 detected in cancer may enhance tumor stem cell formation and/or function. Here, we review the functional and organismal studies of ZNF281/ZBP-99 and its close relative ZBP-89/ZFP148 reported so far. Taken together, ZNF281 related biology has the potential to be translated into cancer diagnostic, prognostic, and therapeutic approaches.

SNAIL and miR-34a feed-forward regulation of ZNF281/ZBP99 promotes epithelial-mesenchymal transition. EMBO J 2013; 32:3079-95.

Abstract
Here, we show that expression of ZNF281/ZBP-99 is controlled by SNAIL and miR-34a/b/c in a coherent feed-forward loop: the epithelial-mesenchymal transition (EMT) inducing factor SNAIL directly induces ZNF281 transcription and represses miR-34a/b/c, thereby alleviating ZNF281 mRNA from direct down-regulation by miR-34. Furthermore, p53 activation resulted in a miR-34a-dependent repression of ZNF281. Ectopic ZNF281 expression in colorectal cancer (CRC) cells induced EMT by directly activating SNAIL, and was associated with increased migration/invasion and enhanced β-catenin activity. Furthermore, ZNF281 induced the stemness markers LGR5 and CD133, and increased sphere formation. Conversely, experimental down-regulation of ZNF281 resulted in mesenchymal-epithelial transition (MET) and inhibition of migration/invasion, sphere formation and lung metastases in mice. Ectopic c-MYC induced ZNF281 protein expression in a SNAIL-dependent manner. Experimental inactivation of ZNF281 prevented EMT induced by c-MYC or SNAIL. In primary CRC samples, expression of ZNF281 increased during tumour progression and correlated with recurrence. Taken together, these results identify ZNF281 as a component of EMT-regulating networks, which contribute to metastasis formation in CRC.

Abstract
ZNF281 is one of the core transcription factors in embryonic stem cells (ESCs) and has activation and repression roles in the transcription of ESC genes. A known target molecule of Zfp281 (the mouse homologue of ZNF281) is Nanog. However, NANOG is not expressed in most human multipotent stem cells (hMSCs). Here, we investigated the roles of ZNF281 with a gain- and loss-of-function study. The knockdown of ZNF281 in vivo and in vitro resulted in spontaneous osteochondrogenic differentiation and reduced the proliferation of hMSCs, as determined by cell morphology and molecular markers. When ZNF281-knockdown hMSCs were subcutaneously implanted into mice along with β-tricalcium phosphate (β-TCP), many cells were converted into osteoblasts within 4 weeks. In contrast, the overexpression of ZNF281 in hMSCs resulted in accelerated proliferation. The expression pattern of ZNF281 correlated well with the expression of β-CATENIN during differentiation and in the gain/loss-of-function study in hMSCs. The binding of ZNF281 to the promoter region of β-CATENIN was observed using a chromatin immunoprecipitation (ChIP) assay. In conclusion, we propose that ZNF281 plays an important role in the maintenance and osteogenic differentiation of stem cells via the transcriptional regulation of genes including β-CATENIN.

Abstract
Embryonic stem cells (ESCs) derived from preimplantation blastocysts have unique self-renewal and multilineage differentiation properties that are controlled by key components of a core regulatory network including Oct4, Sox2, and Nanog. Understanding molecular underpinnings of these properties requires identification and characterization of additional factors that act in conjunction with these key factors in ESCs. We have previously identified Zfp281, a Krüppel-like zinc finger transcription factor, as an interaction partner of Nanog. We now present detailed functional analyses of Zfp281 using a genetically ablated null allele in mouse ESCs. Our data show that while Zfp281 is dispensable for establishment and maintenance of ESCs, it is required for their proper differentiation in vitro. We performed microarray profiling in combination with previously published datasets of Zfp281 global target gene occupancy and found that Zfp281 mainly functions as a repressor to restrict expression of many stem cell pluripotency genes. In particular, we demonstrated that deletion of Zfp281 resulted in upregulation of Nanog at both the transcript and protein levels with concomitant compromised differentiation of ESCs during embryoid body culture. Chromatin immunoprecipitation experiments demonstrated that Zfp281 is required for Nanog binding to its own promoter, suggesting that Nanog-associated repressive complex(es) involving Zfp281 may fine-tune Nanog expression for pluripotency of ESCs.

Abstract
ZBP-89, a Krüppel-type zinc-finger transcription factor that binds to GC-rich sequences, is involved in the regulation of cell growth and cell death. It maps to chromosome 3q21 and is composed of 794 residues. Having bifunctional regulatory domains, ZBP-89 may function as a transcriptional activator or repressor of variety of genes such as p16 and vimentin. ZBP-89 arrests cell proliferation through its interactions with p53 and p21(waf1). It is able to stabilize p53 through directly binding and enhance p53 transcriptional activity by retaining it in the nucleus. In addition, ZBP-89 potentiates in butyrate-induced endogenous p21(waf1) up-regulation. ZBP-89 is usually over-expressed in human cancer cells, where it can efficiently induce apoptosis through p53-dependent and -independent mechanisms. Moreover, ZBP-89 is capable of enhancing killing effects of several anti-cancer drugs. Therefore, ZBP-89 may be served as a potential target in cancer therapy.

Abstract
AIM: To investigate activity of orosomucoid 2 (ORM2) on preS1 promoter (SP Ⅰ) of hepatitis B virus (HBV).
METHODS: Yeast one-hybrid system was employed in screening of DNA-binding proteins specifically recognizing HBV-SP I sequence, in which ORM2 was identified in GenBank by bioinformatics. For further studying the interaction between ORM2 and HBV-SP Ⅰ, the sequence of ORM2 was amplified from HepG2 genome by polymerase chain reaction (PCR) technique, which was then cloned into pcDNA3.1(-) expression vector. The HepG2 cell line was transfected by pCAT3- SP Ⅰ, and co-transfected by pCAT3-SP Ⅰ and pcDNA3.1(-)-ORM2, respectively. The chloramphenicol acetyltransferase (CAT) activity was detected by an enzyme-linked immunosorbent assay (ELISA) kit.
RESULTS: pCAT3-SP Ⅰ had higher activity of CAT than pCAT3-basic by ELISA kit. The expression of CAT from pCAT3-SP Ⅰ was increased 81.9%, as compared with that in the co-transfection of pCAT3-SP Ⅰ and pcDNA3.1(-)-ORM2.
CONCLUSION: Cell transfection and ELISA technology are successfully used to prove the results from yeast one-hybrid system, which brings some new clues for studying the specific binding proteins of HBV- SP Ⅰ and its transcriptional regulation mechanism.

Abstract
Inducible p53-independent regulation of the cyclin-dependent kinase inhibitor p21(Waf1) transcription is mediated through its proximal GC-rich sites. Prior studies have shown that Sp1, Sp3 and the histone acetyltransferase coactivator p300 are components of the complexes that bind to these sites. Although Sp1 and Sp3 collaborate with p300, a direct interaction between Sp1 and p300 does not occur. Zinc-finger binding protein-89 (ZBP-89, also known as BFCOL1, BERF-1 and ZNF-148) is a Krüppel-type zinc-finger transcription factor that binds to the same GC-rich sequences as Sp1. We sought to determine whether ZBP-89 is a target of p300 during butyrate induction of p21(Waf1). This review summarizes the evidence that supports a crucial role for ZBP-89 in butyrate regulation of p21(Waf1). Adenovirus-mediated expression of ZBP-89 in HT-29 cells reveals that ZBP-89 potentiates butyrate induction of endogenous p21(Waf1) gene expression. DNA-protein interaction assays demonstrate that Sp1, Sp3 and ZBP-89 bind the p21(Waf1) promoter at -245 to -215. Coprecipitation assays reveal that p300 preferentially binds to the N-terminus of ZBP-89. ZBP-89 also induces p21(Waf1) through stabilization of p53. Although ZBP-89 binds mutant and wild-type p53, only wild-type p53 is stabilized. Moreover, mutant p53 shifts the subnuclear location of ZBP-89 to the nuclear periphery, which is a domain rich in heterochromatin. This finding led to the conclusion that mutant p53 exerts a dominant negative effect on ZBP-89. We propose that gene silencing by mutant p53 might be mediated by sequestering ZBP-89 within heterochromatin regions at the nuclear periphery. Overall, ZBP-89 is a butyrate-regulated coactivator of p53 and is able to induce p21(Waf1) gene expression through both p53-dependent and -independent mechanisms to inhibit cell growth.
