The meta-analysis was conducted on substantial case-control datasets and revealed a significant correlation between IL6 SNPs (rs1800795 and rs1800796) with overall NDs (p-value < 0.05). The disease-stratified analysis of rs1800795 revealed significant correlations with Schizophrenia, Alzheimer's, and Parkinson's diseases (p-value < 0.05), while rs1800796 showed a substantial connection with Celiac disease (p-value < 0.05). The ethnicity-stratified analysis revealed noteworthy associations between rs1800795 in both Asians and Caucasians (p-value < 0.05), while rs1800796 showed significant associations across all ethnic groups analyzed (p-value < 0.05). Furthermore, integrated Bioinformatics analyses using GTEx and TCGA datasets highlighted IL6's involvement in NDs and its potential role in brain cancer. Specifically, IL6 SNPs (rs1800795 and rs1800797) showed a significant association with Glioma (p-value < 0.001).

Uremic toxicity, oxidative stress, and peripheral-central inflammation have been considered important mediators of CKD-induced nervous disorders. Nitric oxide (NO) is a retrograde neurotransmitter in synapses, and has vital roles in intracellular signaling in neurons. This research aims to determine the effectiveness of NO in CKD-induced cognitive deficits by considering the nuclear factor-erythroid factor 2-related factor 2 (Nrf2)/ heme oxygenase-1 (HO-1) signaling pathway and the important roles of cystathionine beta-synthase (CBS, H2S producing enzyme). Forty rats were divided into four experimental groups: sham, five-sixth (5/6) nephrectomy (5/6Nx, CKD), CKD + NO donor (Sodium nitroprusside, SNP), CKD + SNP and a CBS inhibitor (amino-oxy acetic acid, AOAA). To assess the neurocognitive abilities, eleven weeks after 5/6Nx, behavioral tests (Novel object recognition test, Passive avoidance test, and Barnes maze test) were done. Twelfth week after 5/6Nx, blood urea nitrogen (BUN) and serum creatinine (sCr) levels, as well as the nuclear factor-erythroid factor 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1) expression levels and neuronal injury in the hippocampus and prefrontal cortex were assessed. As predicted, the levels of BUN and sCr (both P < 0.001) and neuronal injury in the hippocampus (P < 0.001 for CA1; CA3; DG) and prefrontal cortex (P < 0.001) increased in CKD rats as well as 5/6Nx induced reduction of Nrf2 (both P < 0.001) /HO-1(P < 0.001; P < 0.01 respectively) pathway activity in the hippocampus and prefrontal cortex in CKD rats. Moreover, CKD leads to cognitive disorder and memory loss (Novel object recognition test (NOR) (P < 0.001), Passive avoidance test (PA) (P < 0.001) and Barnes maze (BA) (Escape latency (P < 0.001); Error (P < 0.001)). SNP treatment significantly improved Nrf2 (both P < 0.001) /HO-1 (P < 0.001; P < 0.05 respectively) pathways and neuronal injury (P < 0.001 for CA1; CA3; DG) in the hippocampus and prefrontal cortex in CKD rats as well as enhanced learning and memory ability in CKD rats.

In this study, the roles played by interferon-stimulated gene 15 (ISG15), HECT, RCC1-containing protein 5 (HERC5), and SERPINE1 mRNA binding protein 1 (SERBP1) in regulating GBM cell stemness were investigated. The real-time quantitative polymerase chain reaction (qPCR), western blotting (WB), and immunohistochemistry (IHC) were used to determine the expression levels of HERC5, ISG15, and SERBP1. Cell stemness was analyzed using a cell sphere formation assay. Colony formation and cell counting kit-8 (CCK-8) assays were performed to assess cell proliferation, Transwell assays used to evaluate cell migration and invasion, and flow cytometry was used to assess cell apoptosis after treatment with temozolomide. SERBP1 stability was assessed by a CHX chase assay. A co-immunoprecipitation (Co-IP) assay verified the binding of ISG15 and HERC5 onto SERBP1. Our results showed that HERC5 and ISG15 were highly expressed in GBM. HERC5 and ISG15 promoted the cell stemness of GBM, and increased cell proliferation, sphere formation, migration, invasion, and chemoresistance. Moreover, HERC5 and ISG15 played a synergistic role in promoting the cell stemness of GBM. We also found that HERC5/ISG15 promoted the stability of SERBP1, which also promoted the cell stemness of GBM. The tumor-promoting role of HERC5 and ISG15 was also confirmed in a subcutaneous xenograft tumor model.

Using publically available gene expression data for the hippocampus from both healthy and AD subjects, differentially expressed genes (DEGs) were identified. Subsequent intersection with a comprehensive list of 575 ARGs yielded a subset for enrichment analysis. Machine learning algorithms were employed to identify potential biomarker, which was validated in an AD animal model. Additionally, gene set enrichment analysis was conducted on the biomarker and its interacting genes and microRNAs were predicted through online databases. To assess its biological functions, the expression of the marker was suppressed in an in vitro model to examine cell viability and inflammation-related indicators. Furthermore, following treatment with the inhibitor, the dysregulated metabolites in the hippocampus of the model mice were evaluated. Forty-seven ARGs were ultimately identified, with HSP90B1 emerging as a central marker. HSP90B1 was found to be significantly up-regulated in AD hippocampal samples and its inhibition conferred increased cell viability and reduced levels of inflammatory factors in amyloid β-protein (Aβ)-treated cells. A total of 24 differentially expressed metabolites were confidently identified between model mice and those with low HSP90B1 expression, with bioinformatics analysis shedding light on the molecular underpinnings of HSP90B1's involvement in AD.

Results indicated a significant elevation of NSUN2 in the SD group. Behavioral assessments using the Morris water maze test revealed cognitive impairments. Notably, inhibiting NSUN2 markedly alleviated these cognitive deficits and reduced autophagy in SD mice. Mechanistically, NSUN2 inhibition led to a pronounced decrease in PTEN levels, and the m⁵C modification of PTEN, which was increased by SD, was significantly reduced following NSUN2 knockdown. It was found that NSUN2 stabilizes PTEN mRNA through methylation. In the SD group, PTEN protein levels were elevated, and this increase was counteracted by NSUN2 inhibition. Collectively, the upregulation of PTEN may diminish the beneficial effects of NSUN2 inhibition on cognitive function and autophagy in SD mice.

To investigate these effects, we used a rat model of middle cerebral artery occlusion (MCAO) and an in vitro model with the C2C12 cell line to uncover potential molecular mechanisms underlying IL-6-induced muscle atrophy. Our findings revealed elevated protein and serum levels of IL-6, along with increased markers of muscle atrophy, in MCAO rats compared to sham controls.

The datasets GSE36980 and GSE48350 were downloaded from the GEO database and visualized using R packages to obtain DEGs.
