This study aimed to use text mining and microarray data analysis to identify drugs that target genes and potential pathways associated with ***: We extracted a common set of genes associated with PCOS using text mining and the microarray dataset GSE48301. Next, we performed Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses of these genes, as well as protein–protein interaction (PPI) network analysis. Additionally, we used MCODE and cytoHubba to cluster significant common genes in the PPI network and performed gene–drug interaction analyses to identify potential drugs for further investigation. Finally, we annotated pathways associated with the genes ***: Text mining and microarray analysis yielded 696 text mining genes (TMGs) and 2804 differentially expressed genes (DEGs). Among these, a set of 77 genes was found in both TMGs and DEGs. Interestingly, 67 of these genes participated in constructing the PPI network. Seven common hub genes were selected using the MCODE and CytoHubba methods. Finally, five out of seven genes were targeted by 15 existing ***: Four genes (FASLG, IL13, IL17A, andIL2RA), which are mainly related to the cytokine–cytokine receptor interaction pathway, could be prioritized as targets for PCOS.

The source of lithium in Lakkor Co Salt Lake on Qinghai-Tibet Plateau, China: evidence from hydrochemical characteristics and boron isotope

引用

Acta Geochimica 2024年第05期43卷 933-946页

作者： Zheng yan Li Bin Kai Li mao-Yong He Xue Qin Wen Jiang Di Zhou Department of Geoscience and Technology Taiyuan University of TechnologyYingzexi Street State Key Laboratory of Loess and Quaternary Geology Institute of Earth Environment Chinese Academy of Sciences Qinghai Provincial Key Laboratory of Geology and Environment of Salt Lakes Qinghai Institute of Salt Lakes Chinese Academy of Sciences Qinghai Normal University Academy of Plateau Science and Sustainability School of Earth Science and Resources Chang'an University

The availability of lithium resources is of great significance for the development of modern technologies, as well as for civil and military industries. The Qinghai-Tibet Plateau is a region known for its abundance of lithium-rich salt lakes. However, the specific origin of lithium in these lakes is still unknown, which hinders the advancement of the lithium resource business in this region. To research this issue, this study involved the collection of 20 samples from Lakkor Co Salt Lake on Qinghai-Tibet Plateau, encompassing samples of surface brine, cold springs, fresh lakes, and recharge rivers. The composition of anions and cations in these samples was determined. Furthermore, the analysis extensivelyutilizedthePiperthree-linediagram,Gibbs model, and ion proportion coefficient. The findings of this study indicate that as the moves from the recharge water system to salt lake, there is a transition in water type from strong carbonate to moderate carbonate and weak carbonate,as well as Na sulfate. This research based on a similar source of both lithium and boron, utilized ion correlation analysis and boron isotope study in the Lakkor Co area, and analyzed the source and transporting process of lithium. The main origin of lithium in Lakkor Co is the dissolution of lithiumrich rocks, recharge water systems, and deep hydrothermal fluids. These findings are highly significant in enhancing the foundational data of lithium-rich brine resources in the Qinghai-Tibet Plateau and are beneficial for assessing the future development of such deposits.
