It regulates the hypothalamus-pituitary-thyroid axis and various metabolic processes, primarily in the liver and kidney. Research has shown that genetic variations, mainly single nucleotide polymorphism (SNP) in the <em>THRB</em> gene, may be linked to diseases like resistance to thyroid hormone, thyroid-related cancers, neurological and mental disorders. Despite this revelation, a significant gap remains in understanding the impact of SNPs on THRβ cellular function and disease etiology. Thus, the present study investigated the disease-associated missense THRβ-SNPs using both <em>in silico</em> analysis and cell-based assays. The study was initiated with computational analysis of disease-associated THRβ variants to predict the effects of SNPs on receptor conformation, structure, stability, and function. The molecular docking and simulation approach then evaluated the impact of these variants on interactions with T<sub>3</sub> and RXR. Following this, an extensive investigation was conducted into the dynamics and functioning of these receptor variants to address the underlying deviations in their cellular functioning by assessing receptor-subcellular localization, response to T<sub>3</sub> hormone, transcriptional functions, interaction with heterodimeric partner RXR, and receptor-chromatin interactions encountered in healthy and disease states. The study emphasizes that the structural and conformational integrity of THRβ is essential for its normal function, and critical deviations are associated with several metabolic/endocrine disease states. A comprehensive analysis of these disease-associated THRβ variants suggests the prospects of personalized medicine and the development of SNP-based genomic tests.

RNA sequencing datasets, including clinical information of OC patients, were collected from TCGA and GEO databases. Lysosome-related prognostic genes and functional pathways in OC were identified using the lysosome dataset. The prognostic value of the most significant lysosome-related gene, SLAMF7, was estimated using Kaplan-Meier survival analysis.

Based on the functional prediction of lysosome-related genes, T cell activation, immune receptor activity, and lysosomal pathways were significantly enriched in OC. Dimensionality reduction analysis using the random survival forest method confirmed that SLAMF7 was the most significantly different lysosome-related prognostic gene in OC.

Low SLAMF7 expression was positively associated with chemotherapy sensitivity, immune infiltration, and function in OC patients.

Adenovirus-mediated overexpression of ERRγ is sufficient to substantially increase hepatic GDF15 expression and secretion. Genetic ablation of ERRγ expression or pharmacological inhibition of ERRγ transactivation substantially inhibited the upregulation of hepatic GDF15 expression and production in both acute and chronic liver injury. Furthermore, reporter assays showed that ERRγ, but not ERRα or ERRβ, directly binds to and activates the GDF15 gene promoter.</div></div><div><h3>Significance</h3><div>Our findings highlight the crucial role of ERRγ in transcriptional regulation of GDF15 gene expression and production in response to liver damage. Understanding the regulatory mechanisms of GDF15 expression could lead to new therapeutic targets for protecting the liver from various types of injuries and associated diseases.</div></div>","PeriodicalId":18707,"journal":{"name":"Molecular and Cellular Endocrinology","volume":"606 ","pages":"Article 112572"},"PeriodicalIF":3.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144086637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
