Transcription factor 3 promotes migration and invasion potential and maintains cancer stemness by activating ID1 expression in esophageal squamous cell carcinoma. Cancer Biol Ther 2023; 24:2246206. [PMID: 37607071 PMCID: PMC10443991 DOI: 10.1080/15384047.2023.2246206] [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: 03/14/2022] [Revised: 10/09/2022] [Accepted: 06/06/2023] [Indexed: 08/24/2023] Open
Abstract
Transcription factor 3 (TCF3) is a member of the basic Helix - Loop - Helix (bHLH) transcription factor (TF) family and is encoded by the TCF3 gene (also known as E2A). It has been shown that TCF3 functions as a key transcription factor in the pathogenesis of several human cancers and plays an important role in stem cell maintenance and carcinogenesis. However, the effect of TCF3 in the progression of esophageal squamous cell carcinoma (ESCC) is poorly known. In our study, TCF3 was found to express highly and correlated with cancer stage and prognosis. TCF3 was shown to promote ESCC invasion, migration, and drug resistance both from the results of in vivo and in vitro assays. Moreover, further studies suggested that TCF3 played these roles through transcriptionally regulating Inhibitor of DNA binding 1(ID1). Notably, we also found that TCF3 or ID1 was associated with ESCC stemness. Furthermore, TCF3 was correlated with the expression of cancer stemness markers CD44 and CD133. Therefore, maintaining cancer stemness might be the underlying mechanism that TCF3 transcriptionally regulated ID1 and further promoted ESCC progression and drug resistance.

Abstract
The translocation t(1;19)(q23;p13) with the resulting chimeric TCF3::PBX1 gene is the third most prevalent recurrent chromosomal translocation in acute lymphoblastic leukemia and accounts for 3-5% of cases. The molecular background of this translocation has been incompletely studied, especially in adult cases. We characterized the chromosomal breakpoints of 49 patients with TCF3::PBX1 and the corresponding reciprocal PBX1::TCF3 breakpoints in 15 cases at the molecular level, thus providing an extensive molecular overview of this translocation in a well-defined study patient population. Breakpoints were found to be remarkably clustered not only in TCF3 but also in PBX1. No association with DNA repeats or putative cryptic recombination signal sequence sites was observed. A simplified detection method for breakpoint identification was developed and the feasibility of patient-specific chromosomal break sites as molecular markers for detecting measurable residual disease (MRD) was explored. A highly sensitive generic real-time PCR for MRD assessment using these breakpoint sequences was established that could serve as a useful alternative to the classical method utilizing rearranged immune gene loci. This study provides the first extensive molecular data set on the chromosomal breakpoints of the t(1;19)/TCF3::PBX1 aberration in adult ALL. Based on the obtained data a generic MRD method was developed that has several theoretical advantages, including an on average higher sensitivity and a greater stability of the molecular marker in the course of disease.

Abstract
The porcine monomyeloid cell line, or 3D4/21 cells, is an effective tool to study the immune characteristics and virus infection mechanism of pigs. Due to the introduction of the neomycin resistance gene and the SV40 large T antigen gene, its genome has undergone essential changes, which are still unknown. Studying the variation in genome structure, especially the large fragments of insertions and deletions (InDels), is one of the proper ways to reveal these issues. In this study, an All-seq method was established by combining Mate-pair and Shotgun sequencing methods, and the detection and verification of large fragments of InDels were performed on 3D4/21 cells. The results showed that there were 844 InDels with a length of more than 1 kb, of which 12 regions were deletions of more than 100 kb in the 3D4/21 cell genome. In addition, compared with porcine primary alveolar macrophages, 82 genes including the CD163 had lost transcription in 3D4/21 cells, and 72 genes gained transcription as well. Further referring to the Hi-C structure, it was found that the fusion of the topologically associated domains (TADs) caused by the deletion may lead to abnormal gene function. The results of this study provide a basis for elaborating the genome structure and functional variation in 3D4/21 cells, provide a method for rapid and convenient detection of large-scale InDels, and provide useful clues for the study of the porcine immune function genome and the molecular mechanism of virus infection.

Abstract
ATM deletions and/or mutations are recurrent in lymphoid neoplasms while rearrangements are rare. In this study, we used mate pair sequencing (MPseq) technology to characterize two novel ATM rearrangements in one patient with chronic lymphocytic leukemia (CLL) and one patient with T-prolymphocytic leukemia (T-PLL). Both patients showed chromosome 11q22 aberrations encompassing ATM by conventional karyotype and fluorescence in situ hybridization: isolated t(11;13)(q22;q14) in CLL and a complex karyotype with apparent 11q deletion and unbalanced der(14)t(11;14)(q22;p11.2) in T-PLL. MPseq identified ATM-LINC00371 fusion in CLL and ATM-USP28 in T-PLL, both of which led to ATM inactivation, confirmed by loss of immunohistochemical protein expression. Next-generation sequencing mutation analysis detected concurrent ATM mutation(s) CLL patient, while T-PLL lacked ATM mutation. ATM rearrangements, not apparently detectable using standard laboratory technologies, represent another mechanism of loss-of-function. Recent high-throughput technologies such as MPseq can uncover novel pathogenic gene fusions and resolve complex chromosomal rearrangements in hematologic malignancies.

Abstract
Acute lymphoblastic leukemia (ALL) is the most frequent malignancy in childhood and adolescence. In more than 60% of cases of this heterogeneous disease, a genetic marker is identified via cytogenetic or molecular analyses. TCF3 gene fusions occur in 5%-11% of ALL patients. In < 1%, the TCF3 alteration in ALL leads to a TCF3-HLF fusion gene. Even though this is a very rare event, the detection of a TCF3-HLF fusion gene is associated with a very poor prognosis with incurable relapses in almost all patients. The frequent TCF3-PBX1 fusion gene, which is detectable in 5%-10% of childhood B-cell precursor ALLs and ~3.8% of adult B-cell precursor ALLs, is associated with a rather good prognosis, that is, an observed event-free 5-year survival of approximately 85%. Thus, the distinction of the different partner genes fused to TCF3 is essential for risk assessment. To verify RNA sequencing as a tool for detection of known and unknown fusion genes, we screened 200 cases of pediatric B-cell precursor ALL with "targeted" RNA sequencing in a pilot project in comparison to classical cytogenetic analyses (chromosome R-banding analysis), fluorescence in situ hybridization, and PCR. We observed a TCF3 fusion gene in 6.5% (13/200) of the patients. Ten (5%) patients displayed a TCF3-PBX1 fusion gene, two (1%) patients a TCF3-FLI1 fusion gene, and one (0.5%) patient a TCF3-HLF fusion gene. For the TCF3 fusions, we obtained discrepant results with the different methods, which are described in the article. Taken together, translocations leading to TCF3 fusion genes might appear cryptic and may remain undetected by a single method.

Front Oncol 2021; 11:709036. [PMID: 34395283 PMCID: PMC8357369 DOI: 10.3389/fonc.2021.709036] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Accepted: 07/12/2021] [Indexed: 11/13/2022] Open
Abstract
Background ZNF384 rearrangements are found in 5-10% of B-cell acute lymphoblastic leukemia (B-ALL) and 48% of B cell/myeloid mixed phenotype acute leukemia (B/M MPAL). ZNF384-rearranged B-ALL is prone to lineage conversion after chemotherapy. TCF3 is the second most common rearrangement partner of ZNF384 in B-ALL (27.5%) and the most common partner in B/M MPAL (53.3%). TCF3-ZNF384 fusion is related to a poor steroid response and a high frequency of relapse. It is mostly reported in children and adolescents but rarely seen in adults. Patients and Methods Here, we report a rare case of adult common B-ALL with TCF3-ZNF384 fusion in which the patient relapsed after one cycle of consolidation chemotherapy. Relapsed leukemia cells from the bone marrow were cultured for 72 hours ex vivo, and a panel of 156 kinds of cytotoxic drugs, targeted therapy drugs, combination chemotherapy drugs, etc., was used for sensitivity screening. The literature on TCF3-ZNF384 fusion was reviewed, and reported cases with TCF3-ZNF384 fusion were summarized. Clinical characteristics were compared between B-ALL and MPAL with TCF3-ZNF384 fusion. Results The relapsed lymphoblasts showed moderate sensitivity to both acute myelocytic leukemia (AML) - and acute lymphoblastic leukemia (ALL)-directed combination chemotherapy schemes, as well as to multiple targeted therapeutic drugs. The hyper-CVAD (B) scheme showed synergistic effects with multiple targeted compounds and had the highest sensitivity. The patient chose the hyper-CVAD (B) scheme combined with sorafenib and achieved complete remission (CR), then consolidated with myeloid-directed homoharringtonine+cytarabine+daunorubicin (HAD) scheme and gained molecular CR. By reviewing the literature, we found that both the genomic landscapes and gene expression profiles of ZNF384-rearranged B-ALL and MPAL are similar and that both diseases have lineage plasticity. The gene expression profile in TCF3-ZNF384-positive patients shows enrichment of hematopoietic stem cell features. No significant differences in clinical characteristics were found between TCF3-ZNF384-positive ALL and MPAL. Conclusion TCF3-ZNF384-positive leukemia may be a distinct subtype of leukemia regardless of immunophenotype. Considering the frequent lineage switches and sensitivity to both ALL- and AML-directed schemes, a uniform strategy directed at both lymphoid and myeloid lineages or at hematopoietic stem cells may be better for TCF3-ZNF384-positive leukemia. Small molecule targeted therapies may be promising treatment options and deserve further investigation.

Abstract
The t(5;14)(q31.1;q32.1) associated with B-lymphoblastic leukemia/lymphoma (B-ALL/LBL) is a rare, recurrent genetic abnormality recognized as a distinct entity by the 2017 World Health Organization (WHO) classification. In these cases, the IGH enhancer region (14q32.1) is juxtaposed to the vicinity of the IL3 gene (5q31.1), resulting in increased production of interleukin-3 (IL3) and subsequently a characteristic reactive eosinophilia. B-ALL with t(5;14)(q31.1;q32.1) may have a low lymphoblast count that can complicate detection of t(5;14)(q31.1;q32.1) by conventional chromosome studies. We have identified four patients with IGH/IL3 rearrangements despite normal conventional chromosome studies in each case [one patient had a non-clonal t(5;14)(q31;q32) finding]. Fluorescence in situ hybridization utilizing a laboratory-developed IGH break-apart probe set identified IGH rearrangements in three of four cases, and a next generation sequencing (NGS) based assay, mate-pair sequencing (MPseq), was required to characterize the IGH/IL3 rearrangements in each case. Three patients demonstrated a balanced t(5;14)(q31.1;q32.1) while one patient had a cryptic insertion of the IL3 gene into the IGH region. These results demonstrate that NGS-based assays, such as MPseq, confer an advantage in the detection of IGH/IL3 rearrangements that are otherwise challenging to characterize by traditional cytogenetic methodologies.

Abstract
The accurate detection of recurrent genetic abnormalities for most hematologic neoplasms is critical for diagnosis, prognosis and/or treatment. Rearrangements involving CCND1 are observed in a subset of mature B-cell neoplasms and can be reliably detected by fluorescence in situ hybridization (FISH) in most cases. However, cryptic and complex chromosomal rearrangements may pose a technical challenge for accurate diagnosis. Herein, we describe two patients with suspected mantle cell lymphoma that lacked obvious CCND1 rearrangements by FISH studies. A next generation sequencing (NGS) based assay, mate-pair sequencing (MPseq), was utilized in each case to investigate potential cryptic CCND1 rearrangements and revealed cryptic insertional events resulting in CCND1/IGH and CCND1/IGK rearrangements. These cases demonstrate that NGS-based assays, including MPseq, are a powerful approach to identify cryptic rearrangements of clinical importance that are not detected by current clinical genomics evaluation.

Abstract
Clinical management and risk stratification of B-lymphoblastic leukemia/ lymphoma (B-ALL/LBL) depend largely on identification of chromosomal abnormalities obtained using conventional cytogenetics and Fluorescence In Situ Hybridization (FISH) testing. In the last few decades, testing algorithms have been implemented to support an optimal risk-oriented therapy, leading to a large improvement in overall survival. In addition, large scale genomic studies have identified multiple aberrations of prognostic significance that are not routinely tested by existing modalities. However, as chromosomal microarray analysis (CMA) and next-generation sequencing (NGS) technologies are increasingly used in clinical management of hematologic malignancies, these abnormalities may be more readily detected. In this article, we have compiled a comprehensive, evidence-based review of the current B-ALL literature, focusing on known and published subtypes described to date. More specifically, we describe the role of various testing modalities in the diagnosis, prognosis, and therapeutic relevance. In addition, we propose a testing algorithm aimed at assisting laboratories in the most effective detection of the underlying genomic abnormalities.
