However, as conflicting findings emerge, ERβ’s tissue-specific expression and functional role have remained elusive. There remains a notable gap in compact and comprehensive analyses of ESR2 mRNA expression levels across diverse tumor types coupled with an exploration of its potential gene network. In this study, we aim to address these gaps by presenting a comprehensive analysis of ESR2 transcriptomic data. We distinguished cancer types with significant changes in ESR2 expression levels compared to corresponding healthy tissue and concluded that ESR2 influences patient survival. Gene Set Enrichment Analysis (GSEA) distinguished molecular pathways affected by ESR2, including oxidative phosphorylation and epithelial–mesenchymal transition. Finally, we investigated genes displaying similar expression patterns as ESR2 in tumor tissues, identifying potential co-expressed genes that may exert a synergistic effect on clinical outcomes, with significant results, includingthe expression of ACIN1, SYNE2, TNFRSF13C, and MDM4 . Collectively, our results highlight the significant influence of ESR2 mRNA expression on the transcriptomic landscape and the overall metabolism of cancerous cells across various tumor types.  \nKeywords: cancer; ESR2; bioinformatic; gene expression; transcriptomic; survival  \n1. Introduction  \nEstrogen receptor β (ERβ) is one of the three predominant 17β-estradiol (E2) receptors in cells, along with estrogen receptor α (ERα) and G-protein-coupled estrogen receptor 1 (GPER1) [1] . ERβ and ERα are members of the nuclear receptor superfamily, while GPER1 is present on cell membranes [2,3] . ERβ is encoded by the gene ESR2, located on chromosome 14, containing eight exons. As ESR2 is susceptible to alternative splicing, it can be transcribed into six isoforms, with ERβ1 characterized as the wild-type, fulllength (530-amino-acids long, 59 kDa) protein [3–5] . For a full review and comparison of different ERs and their structure, we recommend perusing studies by Božovi´c et al. [3] and Jia et al. [1] .  \nERβ displays diverse functions through genomic (nuclear, otherwise called classical) and non-genomic (rapid, extranuclear) pathways [6] . The classical pathways are initiated by the ligand-bound ERβ-E2 complex. This complex translocates into the nucleus, where it orchestrates the transcriptional regulation of target genes. The recognition of target genes can be mediated through the estrogen response element (ERE) canonical","cbCaipYK2rMMFCiY","https://ap.wps.com/l/cbCaipYK2rMMFCiY","pdf",6078600,34,"English","# Introduction\n## ESR2/ERβ background and receptor biology\n## Genomic and non-genomic ERβ signaling\n# Methods and Results\n## ESR2 expression differences across cancer and healthy tissues\n## ESR2 association with patient survival\n## GSEA: pathways related to ESR2\n## ESR2 co-expressed gene identification","[{\"question\":\"What is ESR2 and how is it related to ERβ in cancer biology?\",\"answer\":\"ESR2 encodes estrogen receptor β (ERβ).
