Background: We aimed to determine the cis-expression Quantitative Trait Loci (cis-eQTL) and trans-eQTL of differentially expressed genes (DEGs) in insulin resistance (IR) related pathways.
Methods: The expression profile data for insulin sensitivity (IS) and IR in the adipose tissue of patients with type 2 diabetes mellitus (T2DM) were acquired from the Gene Expression Omnibus databases. Then, the Gene set enrichment analysis (GSEA) and Gene set variation analysis (GSVA) methods were performed to identify the significant enrichment of potential Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways between IS and IR groups, and the Wilcoxon rank sum test was carried out to identify the DEGs related to KEGG pathways. Finally, the cis-eQTLs and trans-eQTLs that can affect the expression of DEGs were screened from the eQTLGen database.
Results: The GSEA and GSVA analysis indicated that the mTOR signaling pathway, insulin signaling pathway and T2DM had a strong correlation with the pathological process of T2DM. Furthermore, six genes (ACACA, GYS2, PCK1, PRKAR1A, SLC2A4, and VEGFA) were found to be significantly differentially expressed in IR-related pathways. Finally, we have identified a total of 1073 cis-eQTLs and 24 trans-eQTLs.
Conclusions: We screened out six genes that were significantly differentially expressed in IR-related pathways, including ACACA, GYS2, PCK1, PRKAR1A, SLC2A4, and VEGFA. Moreover, we discovered that these six genes were affected by 1073 cis-eQTLs and 24 trans-eQTLs.

Severe burns are a major global health concern, and are associated with long-term physical and psychological impairments, multi-organ dysfunction, and substantial morbidity and mortality. While burn injuries in adults trigger systemic immuno-metabolic alterations-characterized by white adipose tissue browning, elevated resting energy expenditure, widespread catabolism, and inflammation-these adaptive responses are considerably impaired in older adults, with molecular mechanisms behind these differences remaining largely unclear. As a key regulator of systemic metabolism, investigating the pathological role of adipose tissue (AT) postburn may reveal novel targets that could potentially improve patient outcomes.

Although ammonia-oxidizing archaea (AOA) are globally distributed in nature, growth in biofilms has been relatively little explored. Here we investigated six representatives of three different terrestrial and marine clades of AOA in a longitudinal and quantitative study for their ability to form biofilm, and studied gene expression patterns of three representatives. Although all strains grew on a solid surface, soil strains of the genera Nitrosocosmicus and Nitrososphaera exhibited the highest capacity for biofilm formation.

Methods: CRC transcriptomic and clinical data from TCGA were analyzed to compare NR1D1 expression in tumors and various clinical stages. Survival differences between high and low NR1D1 expression groups were assessed using the R survival package.
Background: The lncRNA-miRNA-mRNA regulatory network is recognized for its significant role in cardiovascular diseases, yet its involvement in in-stent restenosis (ISR) remains unexplored. Our study aimed to investigate how this regulatory network influences ISR occurrence and development by modulating inflammation and immunity.
Methods: By utilizing data extracted from the Gene Expression Omnibus (GEO) database, we constructed the lncRNA-miRNA-mRNA regulatory network specific to ISR.

Diabetic nephropathy (DN) is a major complication of diabetes, imposing substantial socioeconomic and public health challenges. N6-methyladenosine (m6A) modification, a prevalent epigenetic mechanism, influences cellular processes and disease progression. Wilms' tumor 1-associating protein (WTAP), an m6A methyltransferase subunit, was investigated for its role in DN.
