The potential clinical values of circular RNAs (circRNAs) in cancer diagnosis, prognosis, and treatment have been demonstrated in increasing studies. This research aimed at delving into the specific role of circRNA hsa_circ_0007376 (circMAP2K2) in GC development. CircMAP2K2, miR-556-5p, and CREB5 levels in GC cells and tissues were tested by RT-qPCR. Subcellular fractionation assay was employed for determining the distribution of circMAP2K2 in GC cell cytoplasm and nucleus. The binding potentials between circMAP2K2 (or CREB5) and miR-556-5p were confirmed through luciferase reporter assay. GC cell viability, growth, and metastasis were examined via CCK-8, colony formation, and Transwell assays. CREB5 protein level was assessed via western blot analysis. CircMAP2K2 was upregulated in GC cells and tissues vs. normal controls. CircMAP2K2 depletion hindered GC cell growth, migration, and invasion. Mechanically, circMAP2K2 elevated CREB5 level by completely binding with miR-556-5p. Overexpressing CREB5 abrogated the suppression of circMAP2K2 silencing on GC cell malignant behaviors.

This study aimed to investigate the potential of HDAC4 for predicting PSCI risk. Sixty-nine PSCI patients and 70 control post-stroke (CPS) patients were enrolled in this case-control study. In all stroke patients, HDAC4 in peripheral blood mononuclear cells was detected by quantitative polymerase chain reaction; T-helper 17 (Th17) cells were detected by flow cytometry, and interleukin-17A was detected by enzyme-linked immunosorbent assay. HDAC4 was reduced in PSCI patients compared with CPS patients (P = 0.001). In total stroke patients, HDAC4 showed negative linkages with age (P = 0.003), history of diabetes (P = 0.012), stroke recurrence (P = 0.001), Th17 cells (P = 0.027), and interleukin-17A (P = 0.002). Additionally, multivariate logistic regression analysis revealed that HDAC4 (per unit) [odds ratio (OR) = 0.438, P = 0.024] was independently associated with a lower PSCI risk, but age (per unit) (OR = 1.061, P = 0.016) and multifocal disease (yes vs. no) (OR = 2.490, P = 0.014) were independently associated with a higher PSCI risk. By receiver operator characteristic curves, HDAC4 had an acceptable value for predicting PSCI risk [area under the curve (AUC) = 0.656, 95% confidence interval = 0.566-0.746]. The combination of HDAC4, age, and multifocal disease showed a good value for predicting PSCI risk (AUC = 0.728, 95% confidence interval = 0.644-0.811).

This study will clarify the characteristics of older patients who started medical and long-term care in their place of living following acute inpatient treatment, focusing on the differences between their homes and nursing homes. The analysis was conducted using Japan's nationwide administrative database. We collected discharge records of patients aged 65 and older who received acute inpatient treatment. Those who started medical and long-term care at home or admission a nursing home at the time of discharge were selected and categorized into the home group and the nursing home group. Patient characteristics were shown by group, and factors determining group differences were estimated using univariate and multivariate logistic regression analysis. We selected 89,705 people in the home group and 92,969 in the nursing home group. The home group had a significantly higher rate of cancer, while the nursing home group had a significantly higher age, long-term care need level, and dementia. It became clear that the home group was highly dependent on medical care, and the nursing home group was highly reliant on long-term care. Furthermore, the age group of those admissions to nursing homes varied by sex. These results are expected to provide basic information useful in practice for medical professionals, care workers, and policymakers.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"161-171"},"PeriodicalIF":1.7,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142393539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technology's core includes an extracellular antigen-binding domain, hinge region, transmembrane domain, and intracellular signaling domain, with the single-chain variable fragment (scFv) playing a crucial role in antigen recognition. The paper delves into the immune mechanisms in cardiovascular diseases like heart failure, hypertension, and myocardial infarction, focusing on the roles of T cells in promoting myocardial fibrosis and the therapeutic potential of regulatory T cells (Tregs) in recovery phases. Additionally, it explores the use of lipid nanoparticles (LNPs) carrying mRNA to produce transient, non-integrative CAR-T cells targeting fibroblast activation protein (FAP) to reduce myocardial fibrosis, a method showing promise in preclinical models by enhancing cardiac function and reducing ventricular fibrosis. Despite its potential, the study acknowledges challenges in clinical translation, such as limited therapeutic effects and severe inflammatory responses, highlighting the need for further optimization and research in CAR-T cell technology for cardiovascular disease treatment.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"145-152"},"PeriodicalIF":1.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
