Abstract
8p11 myeloproliferative syndrome (EMS) is a rare and aggressive hematological malignancy, characterized by myeloproliferative neoplasms, and associated with eosinophilia and T- or B-cell lineage lymphoblastic lymphoma. The pathogenesis is defined by the presence of chromosomal translocations associated with the fibroblast growth factor-1 (FGFR1) gene, located in the 8p11-12.1 chromosomal locus. At present, only ~100 cases have been reported globally. At least 15 partner genes have been identified, including the most common, the zinc finger MYM-type containing 2 (ZNF198)-FGFR1 fusion gene formed by t(8;13)(p11;q12). Different fusion genes determine the clinical manifestations and prognosis of the disease. Patients with EMS with t(8;13)(p11;q12) commonly present with lymphadenopathy and T-lymphoblastic lymphoma, which usually converts to acute myeloid leukemia (AML) with the progression of the disease. The present study describes the case of an elderly female patient with EMS with t(8;13)(p11;q12), presenting with myeloid/lymphoid syndrome (myeloproliferative neoplasms and T lymphoblastic lymphoma). The patient received the CHOPE regimen combined with tyrosine kinase inhibitor (dasatin) treatment and obtained short-term complete remission. However, 6 months later, the disease progressed from EMS to AML and the patient died due to ineffective induction therapy. The present study also reviews the relevant literature about this unusual entity to enhance the understanding of EMS.

Abstract
HOOK3, a member of the human hook microtubule-tethering protein family, has been implicated in the progression of cancer. However, the role of HOOK3 in the pathogenesis of gastric cancer (GC) remains incompletely understood. In this study, we investigated the expression of HOOK3 protein in GC tissues using immunohistochemistry (IHC). The findings of our study indicate that the expression levels of HOOK3 in GC tissues were relatively low. Furthermore, a significant negative association was seen between HOOK3 expression and the prognosis of patients with GC. The suppression of HOOK3 resulted in a notable increase in the proliferation, migration, invasion, and survival of GC cells. Conversely, the overexpression of HOOK3 had the opposite impact, reducing these cellular processes. Moreover, in vivo tests have shown evidence that the overexpression of HOOK3 significantly inhibited the formation of tumors and the spread of GC cells to the lungs. In a mechanistic manner, the analysis of RNA-seq data demonstrated that the knockdown of HOOK3 resulted in a notable increase in the expression of vascular endothelial growth factor A (VEGFA) in GC cells. Furthermore, the upregulation of VEGFA counteracted the impacts of HOOK3 upregulation on the proliferation, migration, invasion, and survival of GC cells. Furthermore, it was revealed that specificity protein 1 (SP1) exhibited the ability to bind to the promoter region of VEGFA. Moreover, the overexpression of SP1 successfully counteracted the inhibitory impact of HOOK3 overexpression on the expression of VEGFA in GC cells. In summary, the results of our study indicate that HOOK3 has a role in inhibiting the growth, migration, invasion, and survival of GC cells by modulating the SP1/VEGFA pathway. These findings contribute significant knowledge to our understanding of the underlying mechanisms involved in the development of GC.

Myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase fusion genes: A workshop report with focus on novel entities and a literature review including paediatric cases. Histopathology 2023; 83:829-849. [PMID: 37551450 DOI: 10.1111/his.15021] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 07/04/2023] [Accepted: 07/18/2023] [Indexed: 08/09/2023]
Abstract
Myeloid/lymphoid neoplasms with eosinophilia (M/LN-eo) and tyrosine kinase (TK) gene fusions are a rare group of haematopoietic neoplasms with a broad range of clinical and morphological presentations. Paediatric cases have increasingly been recognised. Importantly, not all appear as a chronic myeloid neoplasm and eosinophilia is not always present. In addition, standard cytogenetic and molecular methods may not be sufficient to diagnose M/LN-eo due to cytogenetically cryptic aberrations. Therefore, additional evaluation with fluorescence in-situ hybridisation and other molecular genetic techniques (array-based comparative genomic hybridisation, RNA sequencing) are recommended for the identification of specific TK gene fusions. M/LN-eo with JAK2 and FLT3-rearrangements and ETV6::ABL1 fusion were recently added as a formal member to this category in the International Consensus Classification (ICC) and the 5th edition of the WHO classification (WHO-HAEM5). In addition, other less common defined genetic alterations involving TK genes have been described. This study is an update on M/LN-eo with TK gene fusions with focus on novel entities, as illustrated by cases submitted to the Bone Marrow Workshop, organised by the European Bone Marrow Working Group (EBMWG) within the frame of the 21st European Association for Haematopathology congress (EAHP-SH) in Florence 2022. A literature review was performed including paediatric cases of M/LN-eo with TK gene fusions.

Abstract
Fusion gene is a new gene formed by the fusion of all or part of the sequences of two genes, it is caused by chromosome translocation, middle deletion or chromosome inversion. Numerous studies in the past have continuously shown that gene fusions are tightly associated with the occurrence and development of various diseases, especially cancer. Many fusion genes have been identified in humans. However, few fusion genes have been identified in fish. In this study, a novel NLRC3-NLRP12 fusion gene was identified in the Miichthys miiuy (miiuy croaker) by quantitative real-time PCR (qRT-PCR), PCR, and Sanger sequencing. This fusion gene is fused by two genes related to NLRs (nucleotide binding domain and oligomerization domain like receptors). We found that the expression of the NLRC3-NLRP12 fusion gene was significantly upregulated after infection with Vibrio anguillarum (V. anguillarum) or stimulation with lipopolysaccharide (LPS). In addition, the NLRC3-NLRP12 fusion gene was strongly induced by V. anguillarum infection, peaking within the kidney and liver at 12 h post infection. Further functional experiments showed that overexpression of NLRC3-NLRP12 significantly inhibited nuclear factor kappa-B (NF-κB) activation. This study suggests that the newly discovered NLRC3-NLRP12 fusion genes may play an important role in innate immunity in miiuy croaker.

Abstract
INTRODUCTION Myeloid/lymphoid neoplasms with fibroblast growth factor receptor-1 (FGFR1) rearrangements (MLNFGFR1) are rare entities with aggressive features and poor prognosis. Presentation is heterogeneous, ranging from myeloproliferative neoplasms (with or without eosinophilia) to T-cell lymphoma and acute leukemia. Historical treatments have been guided by the presenting phenotype with induction chemotherapy frequently used. Pemigatinib is a FGFR1-3 tyrosine kinase inhibitor that has demonstrated high complete hematologic and cytogenetic response rates in MLNFGFR1. AREAS COVERED We discuss the pathogenesis, presentation, and historical treatments for MLNFGFR1, in addition to clinical data using pemigatinib and other targeted therapies. Discussion of the mechanism of action and adverse events are also included. EXPERT OPINION Pemigatinib represents a significant advance in the management of MLNFGFR1. High rates of complete hematologic and cytogenetic response have been observed. While direct comparative data are unavailable, outcomes appear favorable compared to conventional approaches. Long term efficacy and tolerability are not yet known, and allogeneic hematopoietic stem cell transplant (alloHSCT) has been and continues to be the treatment with the highest chance of long term disease free survival in responding patients. Combinations of pemigatinib and chemotherapy, particularly for more aggressive phenotypes, warrant future investigation as does the use of pemigatinib maintenance following alloHSCT.

Abstract
EMS(8p11 myeloproliferative syndrome, EMS) is an aggressive hematological neoplasm with/without eosinophilia caused by a rearrangement of the FGFR1 gene at 8p11-12. It was found that all cases carry chromosome abnormalities at the molecular level, not only the previously reported chromosome translocation and insertion but also a chromosome inversion. These abnormalities produced 17 FGFR1 fusion genes, of which the most common partner genes are ZNF198 on 13q11-12 and BCR of 22q11.2. The clinical manifestations can develop into AML (acute myeloid leukemia), T-LBL (T-cell lymphoblastic lymphoma), CML (chronic myeloid leukemia), CMML (chronic monomyelocytic leukemia), or mixed phenotype acute leukemia (MPAL). Most patients are resistant to traditional chemotherapy, and a minority of patients achieve long-term clinical remission after stem cell transplantation. Recently, the therapeutic effect of targeted tyrosine kinase inhibitors (such as pemigatinib and infigratinib) in 8p11 has been confirmed in vitro and clinical trials. The TKIs may become an 8p11 treatment option as an alternative to hematopoietic stem cell transplantation, which is worthy of further study.
