Aldosterone-producing adenoma (APA) is a common cause of secondary hypertension. This study aimed to explore the lncRNA-miRNA-mRNA competitive endogenous RNA (ceRNA) network to uncover molecular mechanism underlying APA. The mRNA and lncRNA expression data of APA and adjacent adrenal gland (AAG) from GSE60044, GSE64957 and GSE101894 were obtained from the Gene Expression Omnibus (GEO) database to analyse differentially expressed genes (DEGs) and lncRNAs (DElncs). Hub genes were identified by robust rank aggregation (RRA) and protein-protein interaction (PPI) network analysis. The miRcode and miRWalk network tools were used to construct the ceRNA network. 1526 upregulated and 1512 downregulated DEGs were identified, which are mainly enriched in extracellular matrix and Ca -related GO terms. In the KEGG pathway analysis, Ca signalling and the aldosterone synthesis and secretion pathways were enriched. ceRNA network included 2 lncRNAs, 9 miRNAs, and 13 mRNAs. The lncRNAs are MEG3 and LINC00115. The mRNAs included CCND1, TP53, GPRC5B, BMI1, COMMD3-BMI1, ADAMTS15, STAT3, MMP2, SCN2B, CXCL12, HGF, FOS, and THBS1. Overall, this study conducted a ceRNA regulatory network analysis and identified that 2 lncRNAs and 13 mRNAs may contribute to the development of APA. These findings may provide novel diagnostic and intervention targets for APA.

Identification of important genes related to ferroptosis in early missed abortion based on WGCNA.

Early missed abortion is defined as a pregnancy of ≤ 12 weeks in which there is a cessation of life in the developing embryo or fetus, leading to its retention within the uterine cavity without being spontaneously expelled promptly. This condition is commonly observed and significantly impacts human reproductive health. This study aimed to identify key genes related to ferroptosis that could serve as novel biomarkers for early missed abortion.

Background: Recent advances in understanding the regulatory networks implicated in Alzheimer's Disease (AD) evinces the involvement of long non-coding RNAs (lncRNAs) as crucial regulatory players. The present study explores the role played by maternally imprinted lncRNA XIST in regulating the sex-biased prevalence of AD.
Method: With whole transcriptomic sequencing data from the hippocampal RNA of post-mortem AD brains from humans and APP/PS1 mice, the altered expression of XIST in AD was studied.

Acute ischemic stroke (AIS) is a severe disorder characterized by complex pathophysiological processes, which can lead to disability and death. This study aimed to determine necroptosis-associated genes in acute ischemic stroke (AIS) and to investigate their potential as diagnostic and therapeutic targets for AIS. Expression profiling data were acquired from the Gene Expression Omnibus database, and necroptosis-associated genes were retrieved from GeneCards.

Background: Progestin And AdipoQ Receptor Family Member VI () plays a significant role in the non-genomic effects of rapid steroid responses and is abnormally expressed in various tumors. However, its biological function in kidney renal clear cell carcinoma (KIRC) and its potential as a therapeutic target remain underexplored.
Methods: In this study, was identified as a critical oncogene by WGCNA algorithm and differential gene expression analysis using TCGA - KIRC and GSE15641 data.
