Abstract
Transcription factor 3 (TCF3), a pivotal member of the TCF/LEF family, plays a critical role in tumorigenesis. Nonetheless, its impact on the tumor microenvironment (TME) and cancer phenotypes remains elusive. We perform an exhaustive analysis of TCF3 expression, DNA variation profiles, prognostic implications, and associations with the TME and immunological aspects. This study is based on a large-scale pan-cancer cohort, encompassing over 17,000 cancer patients from multiple independent datasets, validated by in vitro assays. Our results show that TCF3/4/7 exhibits differential expression patterns between normal and tumor tissues across pan-cancer analyses. Mutational analysis of TCF3 across diverse cancer types reveals the highest alteration rates in biliary tract cancer. Additionally, mutations and single nucleotide variants in TCF3/4/7 are found to exert varied effects on patient prognosis. Importantly, TCF3 emerges as a robust predictor of survival across all cancer cohorts and among patients receiving immune checkpoint inhibitors. Elevated TCF3 expression is correlated with more aggressive cancer subtypes, as validated by immunohistochemistry and diverse cohort data. Furthermore, TCF3 expression is positively correlated with intratumoral heterogeneity and angiogenesis. In vitro investigations demonstrate that TCF3 is involved in epithelial-mesenchymal transition, migration, invasion, and angiogenesis. These effects are likely mediated through the interaction of TCF3 with the NF-κB/MMP2 pathway, which is modulated by IL-17A in human uveal melanoma MUM2B cells. This study elucidates, for the first time, the significant associations of TCF3 with DNA variation profiles, prognostic outcomes, and the TME in multiple cancer contexts. TCF3 holds promise as a molecular marker for diagnosis and as a potential target for novel therapeutic strategies, particularly in uveal melanoma.

Biomarker potential of the LEF1/TCF family members in breast cancer: Bioinformatic investigation on expression and clinical significance. Genet Mol Biol 2023; 46:e20220346. [PMID: 38100720 PMCID: PMC10723634 DOI: 10.1590/1678-4685-gmb-2022-0346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 10/18/2023] [Indexed: 12/17/2023] Open
Abstract
The LEF1/TCF transcription factor family is related to the development of diverse tissue types, including the mammary tissue, and dysregulation of its expression and function has been described to favor breast tumorigenesis. However, the clinical and biological relevance of this gene family in breast cancer is still poorly understood. Here, we used bioinformatics approaches aiming to reduce this gap. We investigated its expression patterns in molecular and immune breast cancer subtypes; its correlation with immune cell infiltration, and its prognostic values in predicting outcomes. Also, through regulons construction, we determined the genes whose expression is influenced by these transcription factors, and the pathways in which they are involved. We found that LEF1 and TCF3 are over-expressed in breast tumors regarding non-tumor samples, while TCF4 and TCF7 are down-expressed, with the gene's methylation status being associated with its expression dysregulation. All four transcription factors presented significance at the diagnostic and prognostic levels. LEF1, TCF4, and TCF7 presented a significant correlation with immune cell infiltration, being associated with the immune subtypes of less favorable outcomes. Altogether, this research contributes to a more accurate understanding of the expression and clinical and biomarker significance of the LEF1/TCF transcription factors in breast cancer.

Abstract
Background Nucleolar and spindle-associated protein 1 (NUSAP1) plays key roles in microtubules and chromosomes in normal cells both structurally and functionally. In malignancies, NUSAP1 is frequently dysregulated and mutated. However, the expression profiles and biological functions of NUSAP1 in tumors remain unclear. Methods NUSAP1 expression in BALB/c mice and human normal or tumor tissues was examined using immunohistochemistry. Kaplan-Meier survival analysis was utilized to assess the prognostic significance of NUSAP1 in tumors, and principal component analysis and co-expression analysis were performed to explore the unique roles of NUSAP1. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed with DAVID. The relevance between NUSAP1 and tumor-infiltrating immune cells was investigated using TIMER. A transcriptional regulation network was constructed using data from The Cancer Genome Atlas. Results NUSAP1 expression levels in various mice tissues were different. Compared with normal tissues, NUSAP1 was strongly expressed in several human tumor tissues. We believe that NUSAP1 distinctly impacts the prognosis of several cancers and plays various roles in thymoma and testicular germ cell tumors. Further, NUSAP1 expression levels were significantly positively associated with diverse infiltrating levels of immune cells, including B cells, CD4+ and CD8+ T cells, dendritic cells, and macrophages, in thymoma. The expression level of NUSAP1 demonstrated strong relevance with various immune markers in thymoma. Finally, the miR-1236-5p-NUSAP1 and TCF3-NUSAP1 network revealed the tumor-promoting role of NUSAP1 and pertinent underlying mechanisms in human liver hepatocellular carcinoma. Conclusion NUSAP1 may be regarded as a therapeutic target or potential prognostic biomarker for various cancer types.

Abstract
This retrospective single-center study was to evaluate the expression of TCF3 protein in pediatric Burkitt lymphomas (pBLs) and analyze its relations with clinical characteristics and prognosis. A total of 58 pBLs and 30 reactive hyperplastic lymphadenites (RH) were recruited. The high expression rate of TCF3 was 67.24% in pBLs, significantly higher than that in the RHs (36.67%, p = .01), which was consistent with the findings in biopsy specimens from mRNA and protein level, respectively. The expression of TCF3 was significantly associated with tumor localization and size. A total of 54 patients having received short-intensive chemotherapy had a median follow-up of 54.15 months (range: 1-111 months). Log-rank test of Kaplan-Meier survival curves indicated an inverse correlation of TCF3 expression with the overall survival (OS) and event-free survival (EFS). Univariate analysis showed that high TCF3 expression was significantly associated with poor EFS. The result of multivariate COX regression analysis indicated that the TCF3 expression was an independent prognostic factor for EFS.

Abstract
Transcriptional factor 3 (TCF3, also termed E2A), first reported to exert crucial functions during lymphocyte development, has been revealed to participate in the pathogenesis of human cancers. The aim of this work was to investigate the function of TCF3 in cervical cancer (CC) and the molecular interactions. The bioinformatics prediction suggested that TCF3 was highly expressed in CC and linked to poor prognosis. Increased TCF3 expression was identified in CC cell lines, and its downregulation reduced proliferation and migration of CC cells in vitro as well as growth of xenograft tumors in vivo. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses showed that the TCF-3-related genes and genes showed differential expression between CC and normal tissues were mainly enriched in the Wnt/β-catenin pathway. TCF3 bound to sirtuin 1 (SIRT1) promoter for transcriptional activation, and SIRT1 promoted deacetylation and nuclear translocation of β-catenin in CC. SIRT1 overexpression blocked the role of TCF3 silencing and restored cell proliferation in vitro and tumor growth in vivo. Treatment with XAV-939, a β-catenin inhibitor, significantly suppressed the cell proliferation and tumor growth induced by SIRT1 overexpression. In conclusion, this study demonstrates that TCF3 augments progression of CC by activating SIRT1-mediated β-catenin signaling.

Abstract
The epigenetic alteration is widely understood as the key to cancer initiation. Herein, we intended to clarify the role of transcription factor 3 (TCF3) in the development of glioma and the behind epigenetic mechanism. Through bioinformatics analysis, we identified a TCF3-DNA methyltransferase 1 (DNMT1)-secreted frizzled related protein 1 (SFRP1) axis which was differentially expressed and interacted in gliomas. More specifically, TCF3 activated DNMT1 transcription, and DNMT1 repressed SFRP1 expression. TCF3 and DNMT1 were overexpressed, while SFRP1 was downregulated in glioma. Functionally, TCF3 silencing inhibited cell proliferation and migration, and promoted apoptosis, which were reversed by DNMT1. SFRP1 inhibited the tumor supporting effects of DNMT1 on glioma cells. Moreover, TCF3 downregulation or SFRP1 overexpression inhibited tumorigenesis and enhanced apoptosis of glioma cells, while DNMT1 enhanced tumorigenesis and repressed apoptosis in tumor tissues in vivo. The Wnt pathway was a downstream effector of the TCF3-DNMT1-SFRP1 axis. Collectively, this study determined a novel therapeutic target TCF3 for glioma from the perspective of epigenetic alteration via regulation of SFRP1 expression in a DNMT1-dependent manner.

Abstract
Acute myeloid leukaemia (AML) is a biologically heterogeneous disease with an overall poor prognosis; thus, novel therapeutic approaches are needed. Our previous studies showed that 4-amino-2-trifluoromethyl-phenyl retinate (ATPR), a new derivative of all-trans retinoic acid (ATRA), could induce AML cell differentiation and cycle arrest. The current study aimed to determine the potential pharmacological mechanisms of ATPR therapies against AML. Our findings showed that E2A was overexpressed in AML specimens and cell lines, and mediate AML development by inactivating the P53 pathway. The findings indicated that E2A expression and activity decreased with ATPR treatment. Furthermore, we determined that E2A inhibition could enhance the effect of ATPR-induced AML cell differentiation and cycle arrest, whereas E2A overexpression could reverse this effect, suggesting that the E2A gene plays a crucial role in AML. We identified P53 and c-Myc were downstream pathways and targets for silencing E2A cells using RNA sequencing, which are involved in the progression of AML. Taken together, these results confirmed that ATPR inhibited the expression of E2A/c-Myc, which led to the activation of the P53 pathway, and induced cell differentiation and cycle arrest in AML.

Abstract
BACKGROUND Prostate cancer (PCa) is the most common visceral malignancy and the second leading cause of cancer deaths in US men. The two most common genetic alterations in PCa are expression of the TMPRSS2/ERG (TE) fusion gene and loss of the PTEN tumor suppressor. These genetic alterations act cooperatively to transform prostatic epithelium but the exact mechanisms involved are unclear. METHODS Microarray expression analysis of immortalized prostate epithelial cells transformed by loss of PTEN and expression of the TE fusion revealed MEX3D as one of the most highly upregulated genes. MEX3D expression in prostate cancer was examined in patient samples and in silico. In vitro and in vivo studies to characterize the biological impact of MEX3D were carried out. Analysis of the TCGA PanCancer database revealed TCF3 as a major target of MEX3D. The induction of TCF3 by MEX3D was confirmed and the biological impact of TCF3 examined by in vitro studies. RESULTS MEX3D is expressed at increased levels in prostate cancer and is increased by decreased PTEN and/or expression of the TE fusion gene and drives soft agar colony formation, invasion and tumor formation in vivo. The known oncogenic transcription factor TCF3 is highly correlated with MEX3D in prostate cancer. MEX3D expression strongly induces TCF3, which promotes soft agar colony formation and invasion in vitro. CONCLUSIONS Loss of PTEN and expression of the TE fusion gene in prostate cancer strongly upregulates expression of MEX3D and its target TCF3 and promotes transformation associated phenotypes via this pathway.

Abstract
AimsOur previous study has demonstrated that β-catenin pathway was abnormally activated in nasopharyngeal carcinoma (NPC). The purposes of the present study are to investigate whether the alterations of LEF1 and TCF1 (TCF7) proteins, the important components of the canonical Wnt/β-catenin pathway, are associated with clinicopathological features and prognostic implications.MethodsWe collected 391 cases of NPC, 53 non-cancerous control nasopharyngeal mucosa and 28 pairs of NPC and their matched metastases, detected expression of LEF1 and TCF1 (TCF7) proteins in these tissues by immunohistochemistry. ResultsResults showed that there were significantly increased expression of both LEF1 and TCF1 (TCF7) proteins and coexpression of LEF1 and TCF1 (TCF7) in NPC than these in non-cancerous nasopharyngeal mucosa (all p<0.001), as well as LEF1 and coexpression of LEF1 and TCF1 (TCF7) in matched metastasis NPCs than these in the primary NPCs (p=0.003 and p=0.014, respectively). In addition, expression of LEF1 and the coexpression of LEF1 and TCF1 (TCF7) proteins were positively correlated with lymph node metastasis (p=0.001 and p=0.020, respectively), advanced clinical stage (p<0.003 and p=0.027, respectively) and poor survival status of patients with NPC (p<0.001 and p=0.004, respectively). Moreover, multivariate Cox regression analysis identified that the positive expression of LEF1 was the independent poor prognostic factor for overall survival of patients with NPC (p<0.001).ConclusionsThe expression of LEF1 associated positively with TCF1 (TCF7) and clinical progression of NPC, and positive expression of LEF1 protein may act as valuable independent biomarker to predict poor prognosis for patients with NPC.
