This study investigates serum miR-135a levels and their association with regulatory T cell (Treg) and T helper cell 17 (Th17) balance in AR patients. A total of 93 AR patients and 76 healthy controls were retrospectively recruited. Levels of serum miR-135a, peripheral blood Th17 and Treg cells, and Treg/Th17-related cytokines were measured. We assessed the diagnostic value of serum miR-135a for AR and its relationship with Treg/Th17 balance. AR patients showed significantly elevated immunoglobulin E (IgE), peripheral blood Th17 cells, and IL-17 and IL-6 levels, alongside reduced serum miR-135a, Treg cells, IL-10, TGF-β1, and Treg/Th17 ratios. A serum miR-135a of ≤0.536 demonstrated diagnostic potential for AR. Patients with higher serum miR-135a levels displayed increased Treg cell level and Treg/Th17 ratios, reduced Th17 cell, and lower total nasal symptom score (TNSS). Serum miR-135a levels in AR patients negatively correlated with TNSS, IL-17, IL-6, and Th17 cell percentages, and positively correlated with IL-10, TGF-β1, Treg cell percentages, and Treg/Th17 ratios. Collectively, decreased serum miR-135a levels in AR patients are associated with Treg/Th17 balance, supporting miR-135a as a potential biomarker for AR diagnosis.</p>","PeriodicalId":94244,"journal":{"name":"The Kaohsiung journal of medical sciences","volume":" ","pages":"e12918"},"PeriodicalIF":0.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, elucidating the mechanism of its development is crucial for the prevention and treatment of IUA. This study will investigate the function and mechanism of forkhead box P1 (FOXP1)/DNA methyltransferase 1 (DNMT1)/unc-51-like autophagy activating kinase 1 (ULK1) in IUA. Expression levels of key genes were detected using western blot and quantitative - real time reverse transcription polymerase chain reaction. Cell proliferation was detected by CCK-8 and EdU staining. Transcriptional regulation relationships were detected by dual luciferase reporter gene and chromatin immunoprecipitation (ChIP) assay. Methylation station of ULK1 was detected by methylmion specific PCR (MSP). Fibrosis and pathological changes in the uterine cavity tissues were detected by Masson and hematoxylin and eosin staining. It was observed that the expression of FOXP1 and DNMT1 increased in transforming growth factor (TGF)-β1-induced cells, while ULK1 expression decreased. Downregulation of FOXP1 could inhibit human endometrial stromal cells proliferation and autophagy, as well as decrease the expression of fibrogenic factors (collagen type I alpha 1 chain [COL1A1], fibronectin [FN], and alpha-smooth muscle actin [α-SMA]). The results of MSP and ChIP experiments showed that DNMT1 promotes methylation of the ULK1 promoter region and inhibits its transcription. In an animal model, knockdown of FOXP1 alleviated pathological fibrosis and uterine adhesions.

Early prediction of this condition is crucial for prompt intervention. Short-chain fatty acids (SCFAs) and tryptophan are gut metabolites correlated with MAFLD pathogenesis in the gut-liver axis. This study aims to construct prediction models for severe hepatic steatosis by including SCFAs and tryptophan metabolites. This study enrolled 83 participants from the outpatient department in 2023. Physical measurements, serum metabolic and inflammatory markers, metabolites of serum SCFAs and tryptophan were collected. Severe hepatic steatosis was diagnosed using vibration-controlled transient elastography and abdominal sonography. All 40 (48.2%) participants diagnosed with severe hepatic steatosis had MAFLD, while approximately three-quarters of those without severe hepatic steatosis had MAFLD. In comparison to the non-severe hepatic steatosis group, individuals with severe hepatic steatosis exhibited higher levels of waist and arm circumference, serum triglyceride (TG), and lower levels of serum high-density lipoprotein cholesterol (HDL-C) and AST/ALT ratio. They also had higher serum levels of lipopolysaccharide-binding protein, isovaleric acid, and propionic acid, and lower levels of 3-methylvaleric acid, indole-3-propionic acid, and indoxyl sulfate. Models incorporating these markers predicted severe hepatic steatosis. One model additionally included waist circumference and triglyceride-glucose index, while the other incorporated arm circumference and TG/HDL-C ratio. The area under the curve reached 0.958 and 0.938, respectively (p < 0.001). SCFAs and tryptophan metabolites are valuable in predicting severe hepatic steatosis.

After completing the Migraine Disability Assessment (MIDAS) questionnaire, all patients underwent whole-brain high-resolution T1-weighted images, diffusion-weighted imaging, and resting-state functional magnetic resonance imaging at baseline and 6-month follow-up.

In this study, we investigated the molecular mechanisms underlying CBP resistance in RB, with a focus on the role of autophagy and the influence of ubiquitin-specific peptidase 49 (USP49). We observed upregulation of USP49 in RB tissues and cell lines, correlating with disease progression. Functional assays revealed that USP49 promoted aggressive proliferation and conferred CBP resistance in RB cells. Furthermore, USP49 accelerated tumor growth and induced CBP resistance in vivo. Mechanistically, we found that USP49 facilitated CBP resistance by promoting autophagy activation. In addition, we identified insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3)-mediated N6-methyladenosine (m⁶A) modification of USP49 as a regulatory mechanism, wherein IGF2BP3 upregulated USP49 expression in an m⁶A-dependent manner. Moreover, USP49 stabilized SIRT1, a protein associated with CBP resistance and autophagy, by inhibiting its ubiquitination and degradation. Rescue experiments confirmed the pivotal role of SIRT1 in USP49-mediated CBP resistance.

CCK-8 and Edu assays were performed to detect the effects of 30 μM NCF on cell viability and proliferation. TRAP staining and bone resorption assays were performed to observe the role of NCF in osteoclastogenesis and bone resorption. RT-PCR and Western blot were performed to detect the effects of NCF on osteoclast-related genes, glycolysis-related genes, and reactive oxygen species (ROS)-related genes. Seahorse assays, lactate concentration and glucose consumption were performed to observe cell metabolism change. DCFH-DA fluorescent probe was used to detect ROS level. In this work, 30 μM NCF could not influence cell viability and cell proliferation. Osteoclast differentiation could be inhibited by 30 μM NCF. Bone resorption assay could also observe that bone resorption ability was successfully inhibited by 30 μM NCF. In seahorse assay, we discovered that NCF could decrease extracellular acid rate and increase oxygen consumption. RT-PCR and Western blot results showed that NCF could decrease the expression of hexokinase2, pyruvate kinase muscle 2, and lactate dehydrogenase A and that NCF could also weaken the concentration of lactate. However, pyruvate kinase muscle 2 activator (GC69716) and lactate addition could promote osteoclastogenesis and bone resorption and promote the expression of c-Fos and nuclear factor of activated T cells c1.
