Introduction

Plays a role in the signal transduction pathways mediated by multiple Wnt genes (PubMed:24616100). Participates both in canonical and non-canonical Wnt signaling by binding to the cytoplasmic C-terminus of frizzled family members and transducing the Wnt signal to down-stream effectors. Promotes internalization and degradation of frizzled proteins upon Wnt signaling.

Identification of Ferroptosis-related Genes for Diabetic Nephropathy by Bioinformatics and Experimental Validation

Article

Author: Yu, Jiangyi ; Song, Siyuan

Objective:The present study delves into the exploration of diagnostic biomarkers linked with ferroptosis in the context of diabetic nephropathy, unraveling their underlying molecular mechanismsMethods:In this study, we retrieved datasets GSE96804 and GSE30529 as the training cohort, followed by screening for Differentially Expressed Genes (DEGs). By intersecting these DEGs with known ferroptosisrelated genes, we obtained the differentially expressed genes related to ferroptosis (DEFGs). Subsequently, Weighted Correlation Network Analysis (WGCNA) was carried out to identify key modules associated with Diabetic Nephropathy (DN), culminating in the identification of a significant gene. Enrichment analysis and Gene Set Enrichment Analysis (GSEA) were then carried out on the DEFGs and genes linked to the significant gene. To validate our findings, we employed cohorts GSE30528 and GSE43950, utilizing ROC curve analysis to assess diagnostic efficacy for DN, as measured by the area under the curve (AUC). Immune cell infiltration was analyzed and compared between groups using the CIBERSORT algorithm. Bayesian colocalization analysis was performed to examine the co-location of DEFGs and DN. Finally, to validate the hub genes identified, we conducted quantitative real-time polymerase chain reaction (qRT-PCR) experiments in vitro.Results:FUZ, GLI1, GLI2, GLI3, and DVL2 were identified as the hub genes. Functional enrichment analysis demonstrated that ferroptosis and immune response play an important role in DN. ROC analysis showed that the identified genes had good diagnostic efficiency in DN. The results of the immune infiltration analysis showed that there may be crosstalk between ferroptosis and immune cells in DN. Bayesian co-localization analysis revealed the genetic correlation between the hub genes and DN. The outcomes of the qRT-PCR analyses corroborated the reliability of the identified hub genes as robust molecular markers for targeted therapy in DN.Conclusion:The interplay between immune inflammatory reactions and ferroptosis emerges as a crucial pathogenic mechanism, offering novel insights into the molecular therapy of DN. Furthermore, the identification of FUZ, GLI1, GLI2, GLI3, and DVL2 as potential targets holds promise for future therapeutic interventions aimed at treating DN.

Macroautophagy/autophagy dysregulation is associated with various neurological diseases, including Vici syndrome. We aimed to determine the role of autophagy in early brain development. We generated neurons from human embryonic stem cells and developed a Vici syndrome model by introducing a loss-of-function mutation in the EPG5 gene. Autophagy-related genes were upregulated at the neuronal progenitor cell stage. Inhibition of autolysosome formation with bafilomycin A₁ treatment at the neuronal progenitor cell stage delayed neuronal differentiation. Notably, WNT (Wnt family member) signaling may be part of the underlying mechanism, which is negatively regulated by autophagy-mediated DVL2 (disheveled segment polarity protein 2) degradation. Disruption of autolysosome formation may lead to failure in the downregulation of WNT signaling, delaying neuronal differentiation. EPG5 mutations disturbed autolysosome formation, subsequently inducing defects in progenitor cell differentiation and cortical layer generation in organoids. Disrupted autophagy leads to smaller organoids, recapitulating Vici syndrome-associated microcephaly, and validating the disease relevance of our study.Abbreviations: BafA1: bafilomycin A1; co-IP: co-immunoprecipitation; DVL2: dishevelled segment polarity protein 2; EPG5: ectopic P-granules 5 autophagy tethering factor; gRNA, guide RNA; hESC: human embryonic stem cells; KO: knockout; mDA, midbrain dopamine; NIM: neural induction media; NPC: neuronal progenitor cell; qPCR: quantitative polymerase chain reaction; UPS: ubiquitin-proteasome system; WNT: Wnt family member; WT: wild type.

TFE3-rearranged ossifying fibromyxoid tumors are uniquely negative for glycoprotein non-metastatic melanoma protein B: A study of 13 TFE3-rearranged mesenchymal tumors

Article

OBJECTIVESGlycoprotein non-metastatic melanoma protein B (GPNMB) is a transcriptional target of MiTF/TFE3. Prior studies have shown that immunohistochemistry for GPNMB is a sensitive screening tool for renal cell carcinomas with alterations of TSC1/TSC2/MTOR, TFE3, and TFEB genes, as well as alveolar soft part sarcomas (ASPS) and perivascular epithelioid cell neoplasms (PEComas). However, GPNMB expression has not been systematically evaluated in a diverse group of molecularly confirmed, TFE3-rearranged mesenchymal tumors.METHODSOur archive was interrogated for TFE3-rearranged non-renal neoplasms previously assessed with our RNA NGS panel. For each case, a whole-slide section was immunostained for GPNMB, and quantified using H-scores. The methylation profiles of the included tumor types were retrieved from our database.RESULTSThirteen TFE3-rearranged tumors were identified, including 6 ossifying fibromyxoid tumors (OFMTs) (PHF1::TFE3), 3 PEComas/PEComa-like neoplasms (ASPSCR1::TFE3, DVL2::TFE3, and PRCC::TFE3, one case each), 2 YAP1::TFE3-rearranged hemangioendotheliomas, one ASPS (ASPSCR1::TFE3), and one unclassified CBX4::TFE3-rearranged sarcoma. Tumors harboring ASPSCR1, PRCC, YAP1, and DVL2 as the fusion partner had a mean H-score of 300, 300, 290 and 280, respectively. All 6 PHF1::TFE3-rearranged OFMTs and the CBX4::TFE3-rearranged sarcoma were GPNMB-negative, despite having similar TFE3 breakpoints to the positive cases (exon 6-7). PHF1::TFE3-rearranged OFMT showed relative hypermethylation of the GPNMB promoter locus cg02203656 compared to ASPS (p = 0.027).CONCLUSIONSAlthough study of additional cases is necessary, these findings suggest that the downstream effects of TFE3-rearrangement are different in PHF1::TFE3-rearranged OFMTs, compared to other known TFE3-rearranged neoplasms. TFE3-rearranged OFMTs are epigenetically distinct, implying that the impact of TFE3-rearrangement may be lineage-dependent.
