Abstract
CD30 is a member of the tumor necrosis factor receptor (TNFR) superfamily and expressed in both normal and malignant lymphoid cells. However, the role of CD30 in lymphopoiesis is not known. In this study, we showed CD30 was expressed both in T and B cells, but its deficiency in mice had no effect on T- and B-cell development. In fact, CD30 deficiency attenuated B-cell response to T-cell-dependent antigens. The impaired B cell response in CD30-deficient mice is caused by the reduction of activation-induced cytidine deaminase (AID) expression. Moreover, CD30-deficient mice exhibited decreased TCR-mediated T cell proliferation and slightly impaired TCR signaling. High-throughput RNA sequencing analysis revealed that CD30 deficiency led to a decrease of FOXO-autophagy axis in T cells upon TCR stimulation. Thus, CD30 positively regulates T-cell-dependent immune response and T cell proliferation.

Ishikura S, Yoshida K, Tsunoda T, Shirasawa S. Death domain-associated protein DAXX regulates non-coding RNA transcription at the centromere through the transcription regulator ZFAT. J Biol Chem 2022; 298:102528. [PMID: 36162510 PMCID: PMC9579039 DOI: 10.1016/j.jbc.2022.102528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 09/15/2022] [Accepted: 09/17/2022] [Indexed: 11/27/2022] Open
Abstract
The centromere is an essential chromosomal structure for faithful chromosome segregation during cell division. No protein-coding genes exist at the centromeres, but centromeric DNA is actively transcribed into noncoding RNA (ncRNA). This centromeric transcription and its ncRNA products play important roles in centromere functions. We previously reported that the transcriptional regulator ZFAT (zinc-finger protein with AT hook) plays a pivotal role in ncRNA transcription at the centromere; however, it was unclear how ZFAT involvement was regulated. Here, we show that the death domain–associated protein (DAXX) promotes centromeric localization of ZFAT to regulate ncRNA transcription at the centromere. Coimmunoprecipitation analysis of endogenous proteins clearly reveals that DAXX interacts with ZFAT. In addition, we show that ectopic coexpression of ZFAT with DAXX increases the centromeric levels of both ZFAT and ncRNA, compared with ectopic expression of ZFAT alone. On the other hand, we found that siRNA-mediated depletion of DAXX decreases the centromeric levels of both ZFAT and ncRNA in cells ectopically expressing ZFAT. These results suggest that DAXX promotes the centromeric localization of ZFAT and ZFAT-regulated centromeric ncRNA transcription. Furthermore, we demonstrate that depletion of endogenous DAXX protein is sufficient to cause a decrease in the ncRNA levels at the centromeres of chromosomes 17 and X in which ZFAT regulates the transcription, indicating a physiological significance of DAXX in ZFAT-regulated centromeric ncRNA transcription. Taken together, these results demonstrate that DAXX regulates centromeric ncRNA transcription through ZFAT.

Abstract
T helper (Th) cells provide immunity to pathogens but also contribute to detrimental immune responses during allergy and autoimmunity. Th2 cells mediate asthmatic airway inflammation and Th1 cells are involved in the pathogenesis of multiple sclerosis. T cell activation involves complex transcriptional networks and metabolic reprogramming, which enable proliferation and differentiation into Th1 and Th2 cells. The essential trace element zinc has reported immunomodulatory capacity and high zinc concentrations interfere with T cell function. However, how high doses of zinc affect T cell gene networks and metabolism remained so far elusive. Herein, we demonstrate by means of transcriptomic analysis that zinc aspartate (UNIZINK), a registered pharmaceutical infusion solution with high bioavailability, negatively regulates gene networks controlling DNA replication and the energy metabolism of murine CD3/CD28-activated CD4+ T cells. Specifically, in the presence of zinc, CD4+ T cells show impaired expression of cell cycle, glycolytic and tricarboxylic acid cycle genes, which functionally cumulates in reduced glycolysis, oxidative phosphorylation, metabolic fitness and viability. Moreover, high zinc concentrations impaired nuclear expression of the metabolic transcription factor MYC, prevented Th1 and Th2 differentiation in vitro and reduced Th1 autoimmune central nervous system (CNS) inflammation and Th2 asthmatic airway inflammation induced by house dust mites in vivo. Together, we find that higher zinc doses impair the metabolic fitness of CD4+ T cells and prevent Th1 CNS autoimmunity and Th2 allergy.

Abstract
The centromere is a chromosomal locus that is essential for the accurate segregation of chromosomes during cell division. Transcription of noncoding RNA (ncRNA) at the centromere plays a crucial role in centromere function. The zinc-finger transcriptional regulator ZFAT binds to a specific 8-bp DNA sequence at the centromere, named the ZFAT box, to control ncRNA transcription. However, the precise molecular mechanisms by which ZFAT localizes to the centromere remain elusive. Here we show that the centromeric protein CENP-B is required for the centromeric localization of ZFAT to regulate ncRNA transcription. The ectopic expression of CENP-B induces the accumulation of both endogenous and ectopically expressed ZFAT protein at the centromere in human cells, suggesting that the centromeric localization of ZFAT requires the presence of CENP-B. Coimmunoprecipitation analysis reveals that ZFAT interacts with the acidic domain of CENP-B, and depletion of endogenous CENP-B reduces the centromeric levels of ZFAT protein, further supporting that CENP-B is required for the centromeric localization of ZFAT. In addition, knockdown of CENP-B significantly decreased the expression levels of ncRNA at the centromere where ZFAT regulates the transcription, suggesting that CENP-B is involved in the ZFAT-regulated centromeric ncRNA transcription. Thus, we concluded that CENP-B contributes to the establishment of the centromeric localization of ZFAT to regulate ncRNA transcription.

J Cell Biochem 2021; 122:626-638. [PMID: 33522619 PMCID: PMC8248092 DOI: 10.1002/jcb.29890] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 12/22/2020] [Accepted: 12/23/2020] [Indexed: 01/02/2023]
Abstract
Adipocytes play crucial roles in the control of whole‐body energy homeostasis. Differentiation and functions of the adipocytes are regulated by various transcription factors. Zfat (zinc‐finger protein with AT‐hook) is a transcriptional regulator that controls messenger RNA expression of specific genes through binding to their transcription start sites. Here we report important roles of Zfat in the adipocytes. We establish inducible Zfat‐knockout (Zfat iKO) mice where treatment with tamoxifen causes a marked reduction in Zfat expression in various tissues. Tamoxifen treatment of Zfat iKO mice reduces the white adipose tissues (WATs) mass, accompanied by the decreased triglyceride levels. Zfat is expressed in both the adipose‐derived stem cells (ADSCs) and mature adipocytes in the WATs. In ex vivo assays of the mature adipocytes differentiated from the Zfat iKO ADSCs, loss of Zfat in the mature adipocytes reduces the triglyceride levels, suggesting cell autonomous roles of Zfat in the maintenance of the mature adipocytes. Furthermore, we identify the Atg13, Brf1, Psmc3, and Timm22 genes as Zfat‐target genes in the mature adipocytes. In contrast, loss of Zfat in the ADSCs impairs adipocyte differentiation with the decreased expression of C/EBPα and adiponectin. Thus, we propose that Zfat plays crucial roles in maintenance and differentiation of the adipocytes.

Abstract
Centromeres are genomic regions essential for faithful chromosome segregation. Transcription of noncoding RNA (ncRNA) at centromeres is important for their formation and functions. Here, we report the molecular mechanism by which the transcriptional regulator ZFAT controls the centromeric ncRNA transcription in human and mouse cells. Chromatin immunoprecipitation with high-throughput sequencing analysis shows that ZFAT binds to centromere regions at every chromosome. We find a specific 8-bp DNA sequence for the ZFAT-binding motif that is highly conserved and widely distributed at whole centromere regions of every chromosome. Overexpression of ZFAT increases the centromeric ncRNA levels at specific chromosomes, whereas its silencing reduces them, indicating crucial roles of ZFAT in centromeric transcription. Overexpression of ZFAT increases the centromeric levels of both the histone acetyltransferase KAT2B and the acetylation at the lysine 8 in histone H4 (H4K8ac). siRNA-mediated knockdown of KAT2B inhibits the overexpressed ZFAT-induced increase in centromeric H4K8ac levels, suggesting that ZFAT recruits KAT2B to centromeres to induce H4K8ac. Furthermore, overexpressed ZFAT recruits the bromodomain-containing protein BRD4 to centromeres through KAT2B-mediated H4K8ac, leading to RNA polymerase II-dependent ncRNA transcription. Thus, ZFAT binds to centromeres to control ncRNA transcription through the KAT2B-H4K8ac-BRD4 axis.

Abstract
BACKGROUND Prevention of metabolic complications of long-term adjuvant endocrine therapy in breast cancers remained a challenge. We aimed to investigate the molecular mechanism in the development of tamoxifen (TAM)-induced fatty liver in both estrogen receptor (ER)-positive and ER-negative breast cancer. METHODS AND RESULTS First, the direct protein targets (DPTs) of TAM were identified using DrugBank5.1.7. We found that mitogen-activated protein kinase 8 (MAPK8) was one DPT of TAM. We identified significant genes in breast cancer and fatty liver disease (FLD) using the MalaCards human disease database. Next, we analyzed the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of those significant genes in breast cancer and FLD using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING). We found that overlapping KEGG pathways in these two diseases were MAPK signaling pathway, Forkhead box O (FoxO) signaling pathway, HIF-1 signaling pathway, AGE-RAGE signaling pathway in diabetic complications, and PI3K-Akt signaling pathway. Furthermore, the KEGG Mapper showed that the MAPK signaling pathway was related to the FoxO signaling pathway. Finally, the functional relevance of breast cancer and TAM-induced FLD was validated by Western blot analysis. We verified that TAM may induce fatty liver in breast cancer through the MAPK8/FoxO signaling pathway. CONCLUSION Bioinformatics analysis combined with conventional experiments may improve our understanding of the molecular mechanisms underlying side effects of cancer drugs, thereby making this method a new paradigm for guiding future studies on this issue.

Zfat expression in ZsGreen reporter gene knock‑in mice: Implications for a novel function of Zfat in definitive erythropoiesis. Int J Mol Med 2018; 42:2595-2603.

Abstract
Zinc finger and AT-hook domain containing (Zfat) is a transcriptional regulator harboring an AT-hook domain and 18 repeats of a C2H2 zinc-finger motif, which binds directly to the proximal region of transcription start sites in Zfat-target genes. It was previously reported that deletion of the Zfat gene in mice yields embryonic lethality by embryonic day 8.5 and impairs primitive hematopoiesis in yolk sac blood islands. In addition, Zfat has been reported to be involved in thymic T-cell development and peripheral T-cell homeostasis. In the present study, in order to obtain a precise understanding of the expression and function of Zfat, a knock-in mouse strain (ZfatZsG/+ mice), which expressed ZsGreen in the Zfat locus, was established. ZsGreen signals in tissues and cells of ZfatZsG/+ mice were examined by flow cytometric and histological analyses. Consistent with our previous studies, ZsGreen signals in ZfatZsG/+ mice were detected in the embryo and yolk sac blood islands, as well as in thymocytes, B and T cells. In the ZfatZsG/+ thymus, ZsGreen+ cells were identified not only in T-cell populations but also in thymic epithelial cells, suggesting the role of Zfat in antigen-presenting cells during thymic T-cell development. ZsGreen signals were observed in definitive erythroid progenitor cells in the fetal liver and adult bone marrow of ZfatZsG/+ mice. The proportion of ZsGreen+ cells in these tissues was highest at the early stage of erythroid differentiation, suggesting that Zfat serves particular roles in definitive erythropoiesis. Histological studies demonstrated that ZsGreen signals were detected in the pyramidal cells in the hippocampal CA1 region and the Purkinje cells in the cerebellum, suggesting novel functions of Zfat in nervous tissues. Taken together, these results indicated that the ZfatZsG/+ reporter mouse may be considered a useful tool for elucidating the expression and function of Zfat.

Woo HJ, Reifman J. Genetic interaction effects reveal lipid-metabolic and inflammatory pathways underlying common metabolic disease risks. BMC Med Genomics 2018; 11:54. [PMID: 29925367 PMCID: PMC6011398 DOI: 10.1186/s12920-018-0373-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Accepted: 06/12/2018] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Common metabolic diseases, including type 2 diabetes, coronary artery disease, and hypertension, arise from disruptions of the body's metabolic homeostasis, with relatively strong contributions from genetic risk factors and substantial comorbidity with obesity. Although genome-wide association studies have revealed many genomic loci robustly associated with these diseases, biological interpretation of such association is challenging because of the difficulty in mapping single-nucleotide polymorphisms (SNPs) onto the underlying causal genes and pathways. Furthermore, common diseases are typically highly polygenic, and conventional single variant-based association testing does not adequately capture potentially important large-scale interaction effects between multiple genetic factors. METHODS We analyzed moderately sized case-control data sets for type 2 diabetes, coronary artery disease, and hypertension to characterize the genetic risk factors arising from non-additive, collective interaction effects, using a recently developed algorithm (discrete discriminant analysis). We tested associations of genes and pathways with the disease status while including the cumulative sum of interaction effects between all variants contained in each group. RESULTS In contrast to non-interacting SNP mapping, which produced few genome-wide significant loci, our analysis revealed extensive arrays of pathways, many of which are involved in the pathogenesis of these metabolic diseases but have not been directly identified in genetic association studies. They comprised cell stress and apoptotic pathways for insulin-producing β-cells in type 2 diabetes, processes covering different atherosclerotic stages in coronary artery disease, and elements of both type 2 diabetes and coronary artery disease risk factors (cell cycle, apoptosis, and hemostasis) associated with hypertension. CONCLUSIONS Our results support the view that non-additive interaction effects significantly enhance the level of common metabolic disease associations and modify their genetic architectures and that many of the expected genetic factors behind metabolic disease risks reside in smaller genotyping samples in the form of interacting groups of SNPs.

Nishi K, Iwaihara Y, Tsunoda T, Doi K, Sakata T, Shirasawa S, Ishikura S. ROS-induced cleavage of NHLRC2 by caspase-8 leads to apoptotic cell death in the HCT116 human colon cancer cell line. Cell Death Dis 2017; 8:3218. [PMID: 29242562 PMCID: PMC5870588 DOI: 10.1038/s41419-017-0006-7] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 09/25/2017] [Accepted: 09/26/2017] [Indexed: 12/14/2022]
Abstract
Excess production of reactive oxygen species (ROS) is known to cause apoptotic cell death. However, the molecular mechanisms whereby ROS induce apoptosis remain elusive. Here we show that the NHL-repeat-containing protein 2 (NHLRC2) thioredoxin-like domain protein is cleaved by caspase-8 in ROS-induced apoptosis in the HCT116 human colon cancer cell line. Treatment of HCT116 cells with the oxidant tert-butyl hydroperoxide (tBHP) induced apoptosis and reduced NHLRC2 protein levels, whereas pretreatment with the antioxidant N-acetyl-l-cysteine prevented apoptosis and the decrease in NHLRC2 protein levels seen in tBHP-treated cells. Furthermore, the ROS-induced decrease in NHLRC2 protein levels was relieved by the caspase inhibitor z-VAD-fmk. We found that the thioredoxin-like domain of NHLRC2 interacted with a proenzyme form of caspase-8, and that caspase-8 cleaved NHLRC2 protein at Asp580 in vitro. Furthermore, siRNA-mediated knockdown of caspase-8 blocked the ROS-induced decrease in NHLRC2 protein levels. Both shRNA and CRISPR-Cas9-mediated loss of NHLRC2 resulted in an increased susceptibility of HCT116 cells to ROS-induced apoptosis. These results suggest that excess ROS production causes a caspase-8-mediated decrease in NHLRC2 protein levels, leading to apoptotic cell death in colon cancer cells, and indicate an important role of NHLRC2 in the regulation of ROS-induced apoptosis.

Yan H, Wu A. FOXO1 is crucial in glioblastoma cell tumorigenesis and regulates the expression of SIRT1 to suppress senescence in the brain. Mol Med Rep 2017; 17:2535-2542. [PMID: 29207098 DOI: 10.3892/mmr.2017.8146] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2016] [Accepted: 08/14/2017] [Indexed: 11/06/2022] Open
Abstract
In the present study, the role of Forkhead Box O1 (FOXO1) in glioblastoma (GBM) cell tumorigenesis was examined and the underlying mechanisms were investigated. Reverse transcription‑quantitative polymerase chain reaction and western blot analyses were used to analyze the expression of FOXO1 in GBM cell lines (LN18 and T98G) and tissues. Compared with the control groups, FOXO1 was significantly downregulated in the GBM tissues and GBM cell lines (P<0.05). The effects of the expression of FOXO1 on GBM cell proliferation and cell cycle were examined using flow cytometry. The overexpression of FOXO1 markedly inhibited LN18 and T98G cell proliferation and arrested cell cycle at the G0/G1 phase. In addition, FOXO1 facilitated cell senescence through regulation of the expression of sirtuin 1. Epithelial‑mesenchymal transition (EMT) is a complex process, which affects cell growth, invasion and metastasis. The results of the present study revealed that FOXO1 inhibited EMT and metastasis in GBM. These finding revealed a novel mechanism of FOXO1 in the suppression of tumorigenesis and metastasis of GBM cells and suggested that FOXO1 may be a potential therapeutic target for treating GBM.

Molecular mechanisms of transcriptional regulation by the nuclear zinc-finger protein Zfat in T cells. BIOCHIMICA ET BIOPHYSICA ACTA-GENE REGULATORY MECHANISMS 2016; 1859:1398-1410. [PMID: 27591365 DOI: 10.1016/j.bbagrm.2016.08.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Revised: 08/18/2016] [Accepted: 08/29/2016] [Indexed: 11/22/2022]
Abstract
Zfat is a nuclear protein with AT-hook and zinc-finger domains. We previously reported that Zfat plays crucial roles in T-cell survival and development in mice. However, the molecular mechanisms whereby Zfat regulates gene expression in T cells remain unexplored. In this study, we analyzed the genome-wide occupancy of Zfat by chromatin immunoprecipitation with sequencing (ChIP-seq), which showed that Zfat bound predominantly to a region around a transcription start site (TSS), and that an 8-bp nucleotide sequence GAA(T/A)(C/G)TGC was identified as a consensus sequence for Zfat-binding sites. Furthermore, about half of the Zfat-binding sites were characterized by histone H3 acetylations at lysine 9 and lysine 27 (H3K9ac/K27ac). Notably, Zfat gene deletion decreased the H3K9ac/K27ac levels at the Zfat-binding sites, suggesting that Zfat may be related to the regulation of H3K9ac/K27ac. Integrated analysis of ChIP-seq and transcriptional profiling in thymocytes identified Zfat-target genes with transcription to be regulated directly by Zfat. We then focused on the chromatin regulator Brpf1, a Zfat-target gene, revealing that Zfat bound directly to a 9-bp nucleotide sequence, CGAANGTGC, which is conserved among mammalian Brpf1 promoters. Furthermore, retrovirus-mediated re-expression of Zfat in Zfat-deficient peripheral T cells restored Brpf1 expression to normal levels, and shRNA-mediated Brpf1 knockdown in peripheral T cells increased the proportion of apoptotic cells, suggesting that Zfat-regulated Brpf1 expression was important for T-cell survival. Our findings demonstrated that Zfat regulates the transcription of target genes by binding directly to the TSS proximal region, and that Zfat-target genes play important roles in T-cell homeostasis.
