- Decidualization is essential for embryo implantation and maintenance of pregnancy, during which quiescent endometrial stromal fibroblasts proliferate and differentiate into decidual stromal cells. Emerging evidence indicates that epigenetic regulators, including histone modifications, play critical roles in uterine receptivity, implantation, and stromal cell decidualization. Our previous study demonstrated that loss of histone deacetylase 3 (HDAC3) impairs endometrial receptivity and decidualization, resulting in female infertility. However, the genome-wide transcriptomic alterations responsible for defective decidualization in loss of HDAC3 remain unclear. In this study, uterine-specific Hdac3 knockout (PgrHdac3; Hdac3) mice exhibited decidual defects following 3 days of artificial decidualization. RNA sequencing analysis of uteri from control and Hdac3 mice revealed widespread dysregulation of genes and pathways associated with decidualization. Pathway analysis identified significant alterations in RHOA, AMPK-NOTCH1-HEY1, and oxidative stress-induced senescence signaling, implicating dysregulation of cytoskeletal remodeling, cellular metabolism, and oxidative stress responses in the HDAC3-mediated decidual response. Notably, expression of Limk1, Prkag1, and Cbx2 for key regulators of these pathways was significantly reduced in Hdac3 mice compared with controls. These findings demonstrate that HDAC3 is a key regulator of the transcriptional and signaling networks required for successful decidualization. Collectively, our study provides a comprehensive transcriptomic profile of HDAC3-deficient uteri and uncovers key molecular mechanisms underlying impaired decidualization, thereby advancing our understanding of uterine function and pregnancy establishment. - Source: PubMed

Hong LingjuKe ShaoyingLin ShaozeWu GongleWang Congren - A 50-year-old man presented with lower abdominal pain. Imaging revealed a pelvic mass extending from the right internal iliac vein into the inferior vena cava. Fluorodeoxyglucose-positron emission tomography revealed intense uptake (SUVmax 13.97) without metastasis. Biopsy revealed a biphasic tumor with cartilaginous matrix and staghorn vasculature. Immunohistochemistry indicated positive for SMA, desmin, MyoD1, and NKX3.1. Moreover, genomic analysis identified a HEY1::NCOA2 fusion, confirming mesenchymal chondrosarcoma (MCS). Given the extent of the tumor, chemoradiotherapy was initiated. MCS is a rare, high-grade sarcoma with limited treatment options. Targeted therapies against HEY1::NCOA2-associated pathways are promising and are currently under investigation. - Source: PubMed

Ichikawa JiroOnohara KojiroInoue TomohiroWako MasanoriKawasaki Tomonori - Notch receptor activation requires γ-secretase-mediated release of Notch intracellular domain 1 (NICD1) to regulate gene transcription. Here, we identify the proton-driven solute carrier 11a2 (Slc11a2) or divalent metal transport protein Dmt1 as an inhibitor of Notch signaling via regulating iron homeostasis and lysosomal integrity. Dmt1 loss reduces ferritin levels and increases labile Fe, causing elevated reactive oxygen species (ROS) and lipid peroxidation. These changes compromise lysosomal function and impair degradation of S3-Val1744 cleaved NICD1, resulting in its accumulation. Dmt1 has isoforms with or without an iron-responsive element (IRE): Re-expressing Dmt1 + IRE robustly increases ferritin heavy-chain (FTH), whereas Dmt1-IRE moderately elevates FTH and ferritin light-chain (FTL), with co-expression further enhancing FTL levels. Restoration of Dmt1 expression rescues ferritin levels, lysosomal activity, and NICD1 degradation while reducing oxidative stress and lipid peroxidation. Notably, Dmt1 deficiency decreases NICD1 binding to RBP-Jκ/CSL and its recruitment to Notch target gene promoters Hes1 and Hey1. Collectively, our findings demonstrate that Dmt1 regulates lysosomal function through iron homeostasis and that lysosomal dysfunction from Dmt1 loss impairs NICD1 degradation and disrupts Notch signaling, linking cellular iron metabolism and Notch pathway activity. - Source: PubMed

Zhang RuiAhmadian SomaiehPiepers JolandaBock FlorianKeulers TomVooijs Marc A - Erythroid acute myeloid leukemia (AML) cell line OCI-M2 expresses a particular oncogenic network: IRF6, in concert with ETV2 and HEY1, aberrantly activates NKL homeobox gene NKX2-4, which in turn represses megakaryocytic lineage factor FLI1. Interestingly, in keratinocytes, IRF6 is able to bind glucose which promotes IRF6-dimerization and thus alters its binding site selection. Here, we used OCI-M2 as a model to investigate the role of glucose level and IRF6 in leukemogenesis. Treatment of OCI-M2 with high glucose or 2-deoxy-glucose resulted in the downregulation of IRF6 and NKX2-4, and the upregulation of FLI1, indicating that glucose-mediated dimerization of IRF6 altered its reported autoactivation. The screening of this cell line for genes encoding glycolytic enzymes identified aberrant overexpression of glucose-6-phosphate isomerase (GPI) and phosphofructokinase L (PFKL), which were targeted by genomic amplification and chromothripsis-like alterations, respectively. Furthermore, GPI was activated by NKX2-4 and ETV2, and PFKL by ETV2. Finally, siRNA-mediated downregulation of PFKL resulted in elevated glucose levels, suppressed expression of IRF6 and NKX2-4, and activated FLI1. Thus, we connected an oncogenic regulatory network with deregulated glycolytic enzymes and glucose metabolism, thereby establishing a new in vitro model to develop novel therapeutic avenues in AML subsets. - Source: PubMed
