- Small intestinal adenocarcinoma (SIAC) is a rare malignancy with a rising incidence and poor prognosis. Although exportin-7 (XPO7) is typically characterized as a tumor suppressor, recent evidence suggests context-dependent oncogenic functions, yet its role in SIAC remains unexplored. This study evaluated the clinicopathological significance of XPO7 expression and its association with status, autophagy, and cancer stemness in 191 surgically resected primary SIAC cases using immunohistochemistry and automated digital quantification. XPO7 was significantly upregulated in SIAC compared to normal mucosa ( < 0.001). High XPO7 expression, observed in 27.2% of cases, correlated with higher histological grade ( = 0.023) and was identified as an independent predictor of poor overall survival (hazard ratio = 1.703; = 0.008). Subgroup analysis revealed that high XPO7 levels were associated with significantly shorter median overall survival specifically in cases featuring lymphovascular invasion, nodal metastasis, and mutations. Furthermore, XPO7 expression demonstrated a significant positive correlation with autophagy markers (LC3B and p62) but not with stemness markers (Sox2, Oct4, and Nanog). In conclusion, XPO7 serves as a significant independent prognostic biomarker for SIAC, and its correlation with autophagy markers in aggressive subgroups highlights its potential as a promising therapeutic target. - Source: PubMed

Kim Jeong WonYlaya KrisChung Eun JooJun Sun-YoungHong Seung-MoChung Joon-Yong - Schizophrenia is a highly heritable psychiatric disorder, yet the molecular mechanisms by which genetic risk contributes to disease pathophysiology remain largely unknown. In this study, we investigate the functional consequences of XPO7 loss of function (LoF) in human induced pluripotent stem cell (iPSC)-derived neurons, focusing on its role as a schizophrenia risk gene identified through recent large-scale exome sequencing analyses. By integrating high-precision electrophysiological measurements with transcriptomic, proteomic, and imaging approaches, we demonstrate that XPO7 LoF alters Na channel properties and availability, disrupts neuronal excitability, and impairs the synchrony and regularity of network activity. These functional deficits are accompanied by widespread molecular dysregulation affecting nucleocytoplasmic transport, ion channel function, and synaptic composition. Among the dysregulated proteins is Na1.2, a voltage-gated sodium channel encoded by SCN2A, which displays aberrant subcellular distribution in XPO7 LoF neurons. Together, these findings position XPO7 as a critical regulator of neuronal excitability and connectivity, linking channelopathy to cellular phenotypes relevant to schizophrenia pathophysiology. - Source: PubMed

Skwarska AnnaKonopleva Marina - Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse effect of antiresorptive and antiangiogenic therapies, yet its molecular mechanisms remain poorly defined. The present study employed an analysis of microarray data (GSE7116) from peripheral blood mononuclear cells of patients with multiple myeloma, myeloma patients with MRONJ, and healthy controls. Differentially expressed genes were identified using the limma package, followed by functional enrichment analysis, weighted gene co-expression network analysis, and LASSO regression and CytoHubba network ranking. The predictive performance was validated by means of nested cross-validation, Firth logistic regression, and safe stratified 0.632+ bootstrap ridge regression. The profiling revealed distinct gene expression patterns between the groups: the upregulation of ribosomal and translational pathways, as well as the suppression of neutrophil degranulation and antimicrobial defense mechanisms, and identified key candidate genes, including , , , , , , and . These genes demonstrated substantial discriminatory capability, with an area under the curve ranging from 0.95 to 0.99, and were found to be functionally linked to immune system dysfunction, cytokine signaling, NF-κB activation, and a maladaptive stress response. These findings link MRONJ to systemic immune-inflammatory imbalance and translational stress disruption, offering novel insights and potential biomarkers for diagnosis and risk evaluation. - Source: PubMed

Laputková GalinaTalian IvanSabo Ján - Acute myeloid leukemia (AML) with TP53 mutations is almost universally refractory to chemotherapy, molecular-targeted therapies, and hematopoietic stem cell transplantation, leading to dismal clinical outcomes. The lack of effective treatments underscores the urgent need for novel therapeutic strategies. Using genome-wide CRISPR/Cas9 dropout screens in isogenic Trp53-wild-type (WT) and Trp53-knockout mouse AML models, combined with transcriptomic and proteomic analyses of AML samples from mice and humans, we identify the XPO7-NPAT (exportin 7-nuclear protein, coactivator of histone transcription) pathway as essential for TP53-mutated AML cell survival. In TP53-WT AML, XPO7 functions as a tumor suppressor by regulating the nuclear abundance of p53 protein, particularly when basal levels of functional p53 are high. However, in TP53-mutated AML, XPO7 drives leukemia proliferation by retaining NPAT, an XPO7-associated protein predominantly expressed in TP53-mutated AML, within the nucleus. NPAT depletion induces genome-wide histone loss, compromises genomic integrity, and triggers replication catastrophe in TP53-mutated AML cells. Notably, the analysis of publicly available AML data sets, primary AML samples, and single-cell intrapatient mRNA profiles further reveals elevated XPO7 and NPAT expression in TP53-mutated AML. Finally, we validate the XPO7-NPAT pathway as a critical driver of leukemia progression in vivo using patient-derived xenograft models of TP53-WT and TP53-mutant AML. Our study delineates key molecular mechanisms underlying TP53-mutated AML pathogenesis and identifies the XPO7-NPAT axis as a critical vulnerability in this refractory leukemia subtype. - Source: PubMed
