- Fibroblast growth factor (FGF) signaling plays an important role in the pathogenesis of various respiratory diseases, including idiopathic pulmonary fibrosis (IPF). FGF ligands can exert both pro- and anti-fibrotic effects, depending on the responding cell, the expression levels of FGF receptors (FGFR1-4) and the context of other signaling molecules such as Transforming growth factor β (TGF-β). We evaluated here the effect of a modified version of a soluble FGFR3 decoy receptor (designated as "sFGFR3-Fc"), that specifically sequesters pro-fibrotic FGFR3 ligands, FGF1, FGF2 and FGF9 as a potential anti-fibrotic drug. We showed that FGF2 stimulated proliferation and expression of various fibrotic markers in human pulmonary fibroblasts from healthy donors and IPF patients. The sFGFR3-Fc was able to reduce these FGF2-mediated responses and also partially attenuate the pro-fibrotic phenotype induced by TGF-β, including gel contraction. Furthermore, single cell transcriptomic analyses revealed heterogeneity of IPF-derived fibroblasts for FGF2 response and confirmed the potential efficacy of sFGFR3-Fc in decreasing the expression of a subset of TGF-β1 pathway genes. Finally, sFGFR3-Fc was shown to improve the progression of pulmonary fibrosis using both a preventive and therapeutic strategy, evaluated in the standard single bleomycin (BLM) instillation mouse model as well as in a more severe model of repeated BLM instillations, as evidenced by the reduction in ECM deposits, the recovery of body weight and the restoration of lung function. Our data highlight the interplay between the TGF-β and the FGF signaling pathways and demonstrate the potential of targeting pro-fibrotic FGFR3 ligands as therapeutic strategy for IPF. - Source: PubMed

Here we explore the 3D chromatin landscape of sex determination in vivo by profiling fluorescence-activated cell-sorted embryonic mouse gonadal populations in both sexes before and after sex determination. Through conventional Hi-C analyses, we show that chromatin structures, particularly topologically associating domains, remain largely unchanged during sex determination, suggesting a preformed configuration. We further integrate Hi-C data with ChIP-seq experiments using METALoci, a spatial autocorrelation analysis that identifies three-dimensional (3D) regulatory hubs across the genome. We uncover a prominent rewiring of chromatin interactions during sex determination, affecting the 3D regulatory hubs of hundreds of genes that display time-specific and sex-specific expression. By combining predictive approaches and validations in transgenic mice, we identify a 3D regulatory hub for the protesticular gene Fgf9. The deletion of this gonad-specific hub allows mutant mice to survive through development, overcoming lung lethality associated with Fgf9 loss of function while exhibiting male-to-female sex reversal. Through the reconstruction of gene regulatory networks, we identify a function for Meis genes, which act redundantly to specify sexual identity during ovarian and testicular development. Our results underscore the dynamic role of the 3D genome during sex determination, highlighting the potential of epigenomic approaches to uncover regulators of developmental processes. - Source: PubMed

The molecular basis underlying this divergence in Yili horses, however, remains poorly understood. Therefore, we hypothesized that the heterogeneity in fatty acid composition between subcutaneous (SAT) and pericardial adipose tissues (PCAT) in Yili horses is associated with distinct transcriptional programs, which can be explored using an integrated multi-omics approach. Using targeted metabolomics, we found that PCAT contained significantly higher levels of total, saturated, and polyunsaturated fatty acids, but lower monounsaturated fatty acids (MUFAs) compared with SAT. Transcriptomic profiling identified 1513 differentially expressed genes (DEGs), which were primarily enriched in metabolic, endocrine, and signal transduction pathways. Integrative analysis further highlighted , , , , , and as key regulators associated with depot-specific fatty acid differences. Collectively, these findings demonstrate the molecular heterogeneity between SAT and PCAT in Yili horses, support our original hypothesis, and provide a molecular basis for understanding adipose depot-specific lipid metabolism, with potential implications for improving fat deposition traits in Yili horses. - Source: PubMed

Yang LipingShen ZhehongSong LirongLu ZhixinZeng YaqiWang JianwenRen WanluYao XinkuiMeng Jun - Among the disorders of sex development (DSD) with karyotype 46,XY, there is a group of diseases caused by defects of androgen synthesis. The last stage of in the synthesis of androgens is the conversion of testosterone into a more active androgen dihydrotestosterone, which occurs under the influence of the enzyme 5α-reductase type II (SRD5A2). SRD5A2 deficiency is a rare disease with autosomal recessive inheritance. - Source: PubMed

Kalinchenko N YMakretskaya N AKolodkina A AKareva M ATiulpakov A N - This study focuses on the research of the molecular mechanism of myocardial ischemia-reperfusion injury (MIRI) and the exploration of treatment methods. Firstly, through the analysis of differentially expressed genes (DEGs) in 2 datasets, GSE108940 and GSE160516, 229 DEGs were identified. Further, by using the least absolute shrinkage and selection operator regression and random forest analysis, 3 key genes, FAS, PPARA, and FGF9, were screened out. To validate the reliability of these genes, their expression levels were observed in the merged set, experimental set, and validation set. It was found that FAS was highly expressed in the MIRI group, while PPARA and FGF9 were lowly expressed in the MIRI group, and these results were verified in the validation set. In addition, the receiver operating characteristic curve analysis demonstrated that FAS, PPARA, and FGF9 had good diagnostic values, with the area under the curve all >0.8. The study also explored the signaling pathways and molecular mechanisms in MIRI. The Gene Ontology analysis of the DEGs was mainly enriched in responses to interleukin-1, major histocompatibility complex protein complex, and chemokine activity. The Kyoto Encyclopedia of Genes and Genomes enrichment analysis showed that the DEGs were associated with the interaction between viral proteins and cytokines and their receptors, rheumatoid arthritis, and influenza A. The results of cell experiments showed that in the hypoxia/reoxygenation model, the cell viability decreased, and the contents of cTnI, creatine kinase, and lactate dehydrogenase were relatively high. After the administration of the candidate drugs resveratrol and GW4064, the cell viability was significantly improved, and the contents of cTnI, creatine kinase, and lactate dehydrogenase were reduced, indicating a significant effect on repairing damaged cells. Through Western blotting and immunofluorescence techniques, it was found that resveratrol and GW4064 could significantly decrease the expression of FAS and increase the expression of PPARA and FGF9 (P < .01), suggesting that these drugs may have potential therapeutic effects on MIRI. Overall, this study not only provides a new perspective for understanding the molecular mechanism of MIRI but also offers valuable clues for the development of new treatment strategies. - Source: PubMed
