As a chronic condition, liver fibrosis is characterized by diverse etiological factors, and the pivotal event to its pathogenesis is the activation of quiescent hepatic stellate cells (HSCs) into myofibroblasts. Mesenchyme homeobox 1 (MEOX1) is a transcription factors central to cellular development and differentiation. However, the role of MEOX1 signaling in hepatic fibrosis still remains largely unknown. In this study, we investigated the potential role and mechanism of MEOX1 in liver fibrosis using different models in vivo and in vitro. The hepatic expression of MEOX1 exhibited a positive correlation with the degree of fibrosis in patients diagnosed with non-alcoholic steatohepatitis (NASH), as determined through bioinformatics analysis. Furthermore, MEOX1 demonstrated high expression levels in activated HSCs and fibrotic liver tissues induced by methionine and choline-deficient diet (MCD), thioacetamide (TAA), or carbon tetrachloride (CCl₄) treatment in C57/BL6 mice. Mechanistically, MEOX1 facilitated HSC activation, proliferation, and migration. The comprehensive analysis of transcriptome sequencing and chromatin immunoprecipitation sequencing data revealed that connective tissue growth factor (CTGF) served as a target gene for MEOX1 in HSCs. Specifically, MEOX1 bound to the promoter region of CTGF and enhanced its transcriptional activity, thereby mediating the exacerbating effect of MEOX1 on hepatic fibrosis. In conclusion, our current findings elucidate the role of MEOX1 in exacerbating hepatic fibrosis progression through transcriptional activation of CTGF. Our findings provide valuable insights into the therapeutic potential of targeting MEOX1 for the treatment of hepatic fibrosis.

CS1 (SLAMF7), a pivotal immune receptor, plays a dual role in modulating immune responses in autoimmune diseases and cancer. In autoimmunity, aberrant CS1 signaling contributes to the activation of autoreactive lymphocytes, driving pathologies such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Conversely, in oncology, CS1 serves as a promising immunotherapeutic target, exemplified by the efficacy of the monoclonal antibody Elotuzumab in multiple myeloma. CS1 mediates immune cell functions through intricate signaling pathways, including interactions with EAT-2 and SAP adaptors, which influence cytotoxicity, cytokine production, and immune homeostasis. Beyond cancer and autoimmune diseases, soluble and membrane-bound forms of CS1 are emerging as biomarkers and potential therapeutic targets. Despite significant progress, gaps remain in understanding CS1u2019s mechanisms, variability in expression, and role in other diseases. This study explores the multifaceted functions of CS1, proposing innovative strategies to leverage its therapeutic potential across diverse pathologies.

Hydrogel, as the most suitable bio-scaffold material for simulating extracellular matrix, can be used to study the influence of material mechanical properties on cell behavior under 3D conditions. Mechanical stimulation plays an important role in cartilage differentiation, especially for the mechanosensitive cell-bone marrow mesenchymal stem cells (BMSCs). Currently, TRPV4 and Cav1.2 calcium ion channels have been reported to play significant roles in the cartilage differentiation of BMSCs. However, there is no study on whether the effects of these two ion channels vary in different periods of BMSC differentiation, especially in 3D culture. In this article, we clarified the role of TRPV4 and Cav1.2 signaling pathways in the early and late stages of BMSCs cartilage differentiation during 3D culture in hyaluronic acid hydrogel with specific mechanical properties. This research can provide new ideas for further accelerating the stimulation of BMSCs cartilage differentiation and formulating cartilage repair strategies in vivo.

Kinesins are a family of motor proteins essential for intracellular transport and cellular dynamics, with kinesin family member C1 (KIFC1) emerging as a key regulator of cancer progression. Recent studies highlight KIFC1's crucial role in mitotic spindle assembly, chromosome segregation, and cell migration—processes frequently dysregulated in cancer. Its involvement in promoting malignant cell proliferation and metastasis underscores its significance in tumor biology. In various cancer types, aberrant KIFC1 expression correlates with poor prognosis and aggressive phenotypes, suggesting its potential as a biomarker for disease severity. Mechanistically, KIFC1 influences signaling pathways linked to cell cycle regulation and programmed cell death, reinforcing its role in oncogenesis. Given its pivotal function in cancer cell dynamics, KIFC1 represents a promising therapeutic target. Strategies aimed at modulating its activity, including small molecules or RNA interference, could disrupt cancer cell viability and proliferation. The current review article highlights KIFC1's importance in cancer biology, advocating for further investigation into its mechanisms and the development of KIFC1-targeted therapies to enhance treatment efficacy and improve patient outcomes across various malignancies.

Diabetes mellitus (DM) is a chronic widespread metabolic disorder, involving a high blood glucose level which causes multiple serious complications including liver, kidney, brain and peripheral nerves damage. Due to the undesirable side effects of the anti-diabetic drugs, the current studies directed to use stem cells and exosomes to overcome the limitations of traditional therapy. We aimed to compare the antidiabetic effect of Bone marrow mesenchymal stem cells (BMMSCs) and its derived exosomes against diabetic hepatopathy induced by streptozotocin (STZ) in albino rats. Our study was conducted on 28 male albino rats divided into 4 groups {control negative non diabetic group, control positive diabetic group, exosomes treated group received (5 × 10⁹ particle/rat) through tail vein twice per week for one month} and Stem cell treated group received (10⁷) BMMSCs through tail vein twice per week for one month. Hepatic structure together with blood glucose level, liver function enzymes were assayed in addition to a lipid profile tests, oxidative stress, and gene expression. Both treated groups by exosomes and stem cells expressed significantly low levels of fasting blood glucose, liver function parameters (ALT, AST, ALP), lipid profile tests (cholesterol and triglycerides), lipid peroxidation index (MDA), with substantial reduction in IL-1β expression compared to diabetic group. Significantly downregulating the VEGF and elevation of eNOS genes and GSH which suggest the effective role provided by BMMSCs and its derived exosomes for treatment of diabetic hepatopathy. Although, the results of both groups showed near average outcomes, the exosome treated group significantly enhanced liver function enzymes and triglyceride, cholesterol level compared to stem cells treated group. These findings were reinforced by the histopathological and immunohistochemistry examination. The latter showed slight but non-significant improvements in VEGF, eNOS, and IL-1β expression. These minor differences together with practical advantages of exosomes make it preferable over BMMSCs in treatment of diabetic hepatopathy.

The role of kringle-containing transmembrane protein 2 (KRM2) in renal cell carcinoma (RCC) remains unknown. This study aimed to explore KRM2's mechanistic role in regulating RCC progression. Tissue microarrays were used to map KRM2 expression in tumor tissues and analyze its relationship with RCC clinical features. Cell models were constructed by transfecting RCC cell lines with KRM2 knockdown, KRM2 overexpression, or ATF2 knockdown lentiviral vectors. Tumor xenografts were generated in nude mice to observe the effects of KRM2 on tumor formation. A gene expression microarray was used to identify the regulatory genes downstream of KRM2 and their binding relationships were verified by co-immunoprecipitation and cycloheximide pulse-chase assay. Through a series of in vitro experiments, effects of altering KRM2 and ATF2 expression on cell function and ferroptosis indicators were observed. Following these, we found that KRM2 expression significantly increased in RCC tumor tissues and was associated with tumor size, grade, stage, infiltration, and patient age. In vivo experiments confirmed that inhibition of KRM2 expression slowed the tumor growth. Silencing of KRM2 in RCC cells also significantly inhibited cell proliferation and migration and facilitated apoptosis and ferroptosis. ATF2 is predicted to be downstream of KRM2. Its expression is positively regulated by KRM2 and there was targeted binding between proteins. In vitro experiments further suggested that ATF2 knockdown reversed the cancer-promoting and ferroptosis-inhibiting effects of KRM2 in RCC. In conclusion, KRM2 plays an oncogenic role in RCC by promoting tumor progression and ferroptosis via regulation of its downstream target, ATF2.

A growing body of evidence indicates that microRNAs (miRNAs may be used as biomarkers for the diagnosis, prognosis, and treatment of diabetes, given their changed expression profile as the disease progresses. There is growing interest in using individual miRNAs or whole miRNA clusters linked to diabetes as therapeutic targets because of their abnormal expression and functioning. In diabetes, miRNAs are also involved in inflammatory and immunological responses. Additionally, the inflammatory response controls the generation, processing, and stability of pre- or mature miRNAs and miRNA biogenesis. With a comprehensive grasp of molecular biological activities and the signaling axis, this review emphasizes the critical functions of miRNAs in inflammatory and immunological processes in diabetes. We further emphasized the potential role of these miRNAs in controlling inflammation associated with diabetes. This assessment will direct the shift from many studies to practical applications for tailored diabetes treatment and assist in identifying new therapeutic targets and approaches.

Glioblastoma multiforme (GBM) is a brain cancer characterized by low survival and high recurrence rates. Farnesoid X receptor (FXR), a nuclear receptor for bile acids, is expressed at low levels in GBM. This study explores the impact of FXR regulation on GBM cell migration and invasion. Higher FXR expression correlated with increased survival in GBM patients, based on TCGA data. FXR overexpression inhibited cell viability, migration and invasion as well as matrix metalloproteinase 2 (MMP2) activity, while knockdown of FXR exerted the opposite effects. The expression of the tight junction proteins occludin and ZO-1 was enhanced after FXR overexpression. Moreover, a JAK2 activator reversed the migration and invasion of FXR-overexpressing GBM cells. In an animal study, FXR overexpression combined with temozolomide treatment decreased tumor mass, and MMP2 expression and elevated occludin expression in mice. In conclusion, FXR overexpression inhibits the progression of GBM, which may be mediated by inhibiting JAK2 and enhancing tight junction protein expression.

In conclusion, FXR overexpression inhibits the progression of GBM, which may be mediated by inhibiting JAK2 and enhancing tight junction protein expression.</div></div>","PeriodicalId":12227,"journal":{"name":"Experimental cell research","volume":"447 1","pages":"Article 114500"},"PeriodicalIF":3.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143578627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon monoxide (CO) is a novel anti-inflammatory molecule, but the effects of CO on SARS-CoV-2 spike RBD (S-RBD)-induced human bronchial epithelial cytokines release remains unclear. CO was delivered using CO-releasing molecule 3 (CORM-3). The effects of S-RBD, ATPγS and CO on cytokines secretion were determined by enzyme-linked immunosorbent assay (ELISA) in 16HBE14o-human bronchial epithelial cell line. The inhibitory effect of CO on S-RBD-induced ERK phosphorylation was assessed by Western blot analysis. The regulatory effect of CO on extracellular nucleotide-induced ion transport was quantified by short-circuit current (I_SC). S-RBD evoked CCL5 and IL-6 release and this effect could be suppressed by CO. However, CO failed to inhibit ATP release induced by S-RBD while decreased ATP-induced CCL5 and IL-6 secretion as well as ion transport. Furthermore, CO significantly inhibited ERK phosphorylation induced by S-RBD. These findings suggest an anti-inflammatory role of CO during inflammation induced by S-RBD and extracellular nucleotide in human bronchiol epithelial cells.

一氧化碳（CO）是一种新型抗炎分子，但一氧化碳对 SARS-CoV-2 穗状 RBD（S-RBD）诱导的人类支气管上皮细胞因子释放的影响仍不清楚。CO释放分子3（CORM-3）可释放CO。在 16HBE14o- 人支气管上皮细胞系中，通过酶联免疫吸附试验（ELISA）测定了 S-RBD、ATPγS 和 CO 对细胞因子分泌的影响。通过 Western 印迹分析评估了 CO 对 S-RBD 诱导的 ERK 磷酸化的抑制作用。通过短路电流（ISC）量化了 CO 对细胞外 nuleotide 诱导的离子转运的调节作用。S-RBD 可诱导 CCL5 和 IL-6 的释放，CO 可抑制这种效应。然而，CO 未能抑制 S-RBD 诱导的 ATP 释放，但却降低了 ATP 诱导的 CCL5 和 IL-6 分泌以及离子转运。此外，CO 还能明显抑制 S-RBD 诱导的 ERK 磷酸化。这些研究结果表明，CO 在 S-RBD 和细胞外核苷酸诱导的人支气管上皮细胞炎症过程中具有抗炎作用。

Epithelial-mesenchymal transition (EMT) is one of the critical mechanisms underlying migration, invasion, and metastasis of nasopharyngeal carcinoma (NPC) cells. The transcription factor KLF5 plays a pivotal role in various cancers, however, its precise functions in NPC remain incompletely understood. This study aims to explore the detailed mechanisms by which TGF-β enhances TNFAIP2 transcription by acetylating KLF5, thereby inducing EMT in NPC. KLF5 was significantly overexpressed in NPC tissues and closely associated with adverse clinicopathological features of the patients. Further studies revealed that TGF-β markedly increased the expression of KLF5 and its acetylated form, Ac-KLF5, in NPC cells, with the acetylation status of KLF5 being crucial for its function. KLF5 induced EMT in NPC cells by directly binding to the TNFAIP2 promoter and promoting its transcription. The pro-migratory and pro-invasive effects of acetylated KLF5 on NPC cells depended on TNFAIP2. Additionally, in vivo experiments confirmed that TGF-β treatment induced tumors in NPC mouse models to exhibit apparent EMT characteristics. These results collectively support the central role of the TGF-β-KLF5-TNFAIP2 axis in EMT of NPC. This study elucidates the specific mechanisms by which TGF-β promotes TNFAIP2 transcription by acetylating KLF5, thereby inducing EMT in NPC. This discovery not only provides new insights into the pathogenesis of NPC but also identifies potential therapeutic targets for NPC treatment.
