Upregulated and 983 downregulated. The FAA led to recognize one of the most altered biological processes: DE genes have been significantly related to 20 terms using a false discovery price (FDR) p worth 0.05 (Supplementary Table S5 and S6). The most significant terms connected to upregulated genes have been related towards the membrane term, at the same time as to terms connected to inflammatory response, optimistic regulation of ERK1 and ERK2 cascade, signal transduction, chemokine-mediated signaling pathway and good regulation of angiogenesis (Table 1a). However, downregulated genes had been related to terms associated to epithelial cell differentiation, good regulation of cell migration, positive regulation of epithelial cell proliferation, focal adhesion, good regulation of angiogenesis, apical plasma membrane and calcium ion binding (Table 1b). Notably, we detected the downregulation of two genes encoding proteins critical for the establishment of cell ell contacts: CTNNAL1 gene (-catenin) and CDH2 gene (N-cadherin) (Supplementary Table S6), and of the genes encoding the transforming growth aspect beta receptor III (TGFBR3), LAMC2 (laminin-2) and MSX1 (Msh homeobox) (see the genes highlighted in bold in Supplementary Table S6), which are recognized to be downregulated in human EC23,24. By far the most relevant DE genes are indicated in the “most relevant genes” column in Table 1. Additionally, we validated the CB1 Antagonist Compound identified signature with the tumor mass of TG-hLH-R-frt-200 mouse comparing it using the gene expression profile of other ECs obtained from publicly obtainable CA I Inhibitor Formulation datasets deposited in to the GEO databases. We chose the datasets EMTAB2532, EGEOD56026, GSE32507, GSE24537, EGEOD23518, EGEOD17025, EGEOD2109, analysed in O’Mara 2016 and also the datasets GSE17025, GSE63678 and GSE35794, analysed in Liu 201826,27. Two out in the 1701 DE genes identified inside the tumor mass from the TG-hLH-R-frt-200 mouse matched with all the 10 more downregulated genes identified by Liu 2018 in EC, which includes Tgfbr3. When compared together with the 145 extra deregulated genes from O’Mara 2016, 11 typically deregulated genes emerged, including Sox17 and Esr1 (the whole analysis is shown in Supplementary Table S9, and also the most relevant genes in prevalent using the above datasets are highlighted in red in Table 1). General, the transcriptomic analysis with the masses arise in aged TG females supports the conclusion that they’re endometrial tumor masses. We further validated the upregulation of signaling pathways controlling cell proliferation and angiogenesis, by means of an IHC analysis of pAkt, ERK1, VEGF, Ki67 and p53. Each of the tumor masses overexpressed the above markers, and also a statistically significant good correlation emerged amongst c-myc and VEGF, ERK, pAKT, KiScientific Reports |(2021) 11:8847 |https://doi.org/10.1038/s41598-021-87492-7 Vol.:(0123456789)www.nature.com/scientificreports/Figure 4. A: Pathways enrichment evaluation of upregulated (a) and downregulated (b) genes, applying p-values 0.05 as threshold. The transcriptomic analysis was performed on uteri of two 6-months old TG mice (belonging to the TG-hLH-R-frt-200 mouse line) and WT mice. Table shows the quantity plus the percentage of genes involved in each and every pathway, together with the relative fold enrichment. For this analysis the Bonferroni correction was applied.
