Arch Biochem Biophys 2024; 754:109921. [PMID: 38341068 DOI: 10.1016/j.abb.2024.109921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 01/28/2024] [Accepted: 01/30/2024] [Indexed: 02/12/2024]
Abstract
Zinc finger protein 131 (ZNF131), a member of BTB-ZF transcription factors, has been previously reported as an oncogene in several human cancers. However, the function and underlying mechanism of ZNF131 in hepatocellular carcinoma (HCC) are still unclear. In our study, the upregulated expression of ZNF131 mRNA was confirmed in HCC tissues by analyzing the TCGA and GEO datasets. The immunohistochemical staining data also revealed the overexpression of ZNF131 protein in HCC samples. High expression of ZNF131 predicted poor overall survival and disease-free survival in HCC patients. ZNF131 knockdown inhibited the proliferation and colony formation and led to G2/M phase arrest of HCC cells, while its overexpression promoted HCC cell proliferation, cell cycle progression and colony formation. Moreover, ZNF131 silencing repressed the growth of HCC cells in nude mice. Yes-associated protein 1 (YAP1) was recognized as an upstream regulator of ZNF131. Both YAP1 knockdown and inactivation reduced ZNF131 expression in HCC cells, and YAP1 overexpression enhanced ZNF131 level. Interestingly, we found that poly(A) binding protein interacting protein 1 (PAIP1) was a novel target of ZNF131. ZNF131 silencing downregulated while ZNF131 overexpression upregulated PAIP1 expression in HCC cells. The luciferase reporter assay demonstrated that ZNF131 regulated PAIP1 expression at the transcription level. Notably, we revealed that ZNF131 activated the AKT signaling by enhancing PAIP1 expression in HCC cells. AKT inhibitor markedly attenuated ZNF131-enhanced HCC cell proliferation. Restoring PAIP1 expression abrogated the inhibitory effects of ZNF131 knockdown on HCC cell proliferation and colony formation. To conclude, ZNF131 was highly expressed and acted as an oncogene in HCC. ZNF131, which was activated by YAP1, promoted HCC cell proliferation through transcriptional regulation of PAIP1.

Biochem Biophys Res Commun 2024; 696:149515.

Abstract
ZNF131 is a Zinc finger protein that acts as a transcription factor with oncogenic effects in multiple cancers. In this study, we aimed to explore the alternative splicing profile of ZNF131 in hepatocellular carcinoma (HCC), its regulatory effects on cell-cycle progression, and the downstream effectors. ZNF131 transcriptional profile and HCC survival analysis were conducted using data from the Cancer Genome Atlas (TCGA)-Liver Hepatocellular Cancer (LIHC) dataset. Chromatin immunoprecipitation (ChIP)-qPCR and dual-luciferase reporter assays were utilized to explore transcriptional regulation. CCK-8, colony formation and xenograft tumor models were used to study HCC tumor growth. Results showed that ZNF131 isoform 2 is upregulated in HCC tissues and its upregulation was associated with unfavorable overall survival (OS) and progression-free interval (PFI). Knockdown of endogenous ZNF131 inhibits HCC cell growth and induces G2/M cell-cycle arrest. ZNF131 binds to the SMC4 promoter by interacting with ZBTB33 and the ZBTB33 recognizing motif. ZNF131 transcriptionally activates SMC4 expression in HCC cells. The tumor-suppressive effects of ZNF131 shRNA could be partially reversed by enforced SMC4 overexpression. In summary, this study highlights the ZNF131/ZBTB33/SMC4 axis as a driver of pathological cell cycling and proliferation in HCC.

Relationship between High Expression of Kaiso Protein and Poor Prognosis of Lung Cancer and the Regulation Mechanism of Malignant Phenotype of Lung Cancer Cells. JOURNAL OF ONCOLOGY 2021; 2021:7388368. [PMID: 34976058 PMCID: PMC8716232 DOI: 10.1155/2021/7388368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 11/15/2021] [Indexed: 11/18/2022]
Abstract
In this study, Kaiso was discovered to be a unique member of the POZ-zinc fingers family of transcription factors, which has been implicated in the genesis and progression of cancer. Although there is still some debate, Kaiso is believed to be implicated in the development of human cancer. It should be noted that there is minimal evidence available on the therapeutic relevance of nuclear Kaiso in lung cancer in humans. Histone or DNA modifications that control gene activity outside of the underlying sequence are examples of epigenetic alternations. Epigenetic alterations are heritable but reversible. Human illness, such as lung cancer, is often related to epigenetic dysregulation. In preclinical and clinical studies, epigenetic-targeted therapy has shown significant therapeutic promise for solid tumours and has been used in the treatment of haematological malignancies using different medicines targeting epigenetic regulators. It is important to note that the abnormal activities of Kaiso enzymes in tumour growth are summarised below and the development of inhibitors or medicines targeting epigenetic enzyme regulation is highlighted.

Abstract
The development and differentiation of T cells represents a long and highly coordinated, yet flexible at some points, pathway, along which the sequential and dynamic expressions of different transcriptional factors play prominent roles at multiple steps. The large ZBTB family comprises a diverse group of transcriptional factors, and many of them have emerged as critical factors that regulate the lineage commitment, differentiation and effector function of hematopoietic-derived cells as well as a variety of other developmental events. Within the T-cell lineage, several ZBTB proteins, including ZBTB1, ZBTB17, ZBTB7B (THPOK) and BCL6 (ZBTB27), mainly regulate the development and/or differentiation of conventional CD4/CD8 αβ+ T cells, whereas ZBTB16 (PLZF) is essential for the development and function of innate-like unconventional γδ+ T & invariant NKT cells. Given the critical role of T cells in host defenses against infections/tumors and in the pathogenesis of many inflammatory disorders, we herein summarize the roles of fourteen ZBTB family members in the development, differentiation and effector function of both conventional and unconventional T cells as well as the underlying molecular mechanisms.

Cerebrum, liver, and muscle regulatory networks uncover maternal nutrition effects in developmental programming of beef cattle during early pregnancy. Sci Rep 2021; 11:2771.

Abstract
The molecular basis underlying fetal programming in response to maternal nutrition remains unclear. Herein, we investigated the regulatory relationships between genes in fetal cerebrum, liver, and muscle tissues to shed light on the putative mechanisms that underlie the effects of early maternal nutrient restriction on bovine developmental programming. To this end, cerebrum, liver, and muscle gene expression were measured with RNA-Seq in 14 fetuses collected on day 50 of gestation from dams fed a diet initiated at breeding to either achieve 60% (RES, n = 7) or 100% (CON, n = 7) of energy requirements. To build a tissue-to-tissue gene network, we prioritized tissue-specific genes, transcription factors, and differentially expressed genes. Furthermore, we built condition-specific networks to identify differentially co-expressed or connected genes. Nutrient restriction led to differential tissue regulation between the treatments. Myogenic factors differentially regulated by ZBTB33 and ZNF131 may negatively affect myogenesis. Additionally, nutrient-sensing pathways, such as mTOR and PI3K/Akt, were affected by gene expression changes in response to nutrient restriction. By unveiling the network properties, we identified major regulators driving gene expression. However, further research is still needed to determine the impact of early maternal nutrition and strategic supplementation on pre- and post-natal performance.

Abstract
DNA methylation is an essential epigenetic modification involved in the maintenance of genomic stability, preservation of cellular identity, and regulation of the transcriptional landscape needed to maintain cellular function. In an increasing number of disease conditions, DNA methylation patterns are inappropriately distributed in a manner that supports the disease phenotype. Methyl-CpG binding proteins (MBPs) are specialized transcription factors that read and translate methylated DNA signals into recruitment of protein assemblies that can alter local chromatin architecture and transcription. MBPs thus play a key intermediary role in gene regulation for both normal and diseased cells. Here, we highlight established and potential structure-function relationships for the best characterized members of the zinc finger (ZF) family of MBPs in propagating DNA methylation signals into downstream cellular responses. Current and future investigations aimed toward expanding our understanding of ZF MBP cellular roles will provide needed mechanistic insight into normal and disease state functions, as well as afford evaluation for the potential of these proteins as epigenetic-based therapeutic targets.
