Effective targeted drugs are still lacking, and the presence of glioblastoma stem cells (GSC) is a major factor contributing to radiotherapy resistance. Screening for targeted drugs that can sensitize GBM to radiotherapy is crucial. FTO is considered an attractive potential target for tumor therapy, as it mediates m6A demethylation to regulate the stability of target genes. In this study, we evaluated the role of FTO inhibition in promoting the sensitivity of GSC cells to radiotherapy through tumor sphere formation assays, cell apoptosis assays, and in situ GSC tumor models. We preliminarily explored the molecular mechanisms by transcriptome sequencing and m6A methylation sequencing to investigate how inhibiting FTO increases radiotherapy sensitivity. The results showed that downregulation of FTO expression or FTO inhibitor FB23-2 combined with radiotherapy significantly inhibited GSC cell proliferation and self-renewal and increased apoptosis. FB23-2 combined with radiotherapy effectively inhibited intracranial tumor growth in mice and prolonged the survival of tumor-bearing mice. Furthermore, FTO inhibition sustained the increase of γH2AX expression induced by radiotherapy while decreasing Rad51 expression. Importantly, we found that inhibiting FTO could increase m6A methylation modification of VEGFA, thereby downregulating both mRNA and protein expression of VEGFA. Our findings provide a new therapeutic strategy for enhancing GBM radiotherapy sensitivity and lay the theoretical and experimental groundwork for clinical trials targeting FTO.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"132 ","pages":"Article 111782"},"PeriodicalIF":4.4,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies suggest that TRIP4 acts as a transcription factor to regulate cervical carcinogenesis and progression. Our aim was to explore whether the key downstream genes of TRIP4 functions same as TRIP4 in promoting cervical cancer development. We analyzed and confirmed the downstream targets of TRIP4 by RNA sequencing in cervical cancer cells with TRIP4 knockdown. The expression correlation between TRIP4 and GATA2 and the effect of GATA2 on cervical cancer cell growth were determined respectively by Western Blot, Scratch, Spheroid, and MTT analyses. Pulldown and ChIP experiments were performed to analyze the binding of TRIP4 to the promoter of GATA2. The clinical significance of GATA2 and TRIP4 expression in cervical cancer patients was analyzed by tissue microarray staining. GATA2 was highly expressed in cervical cancer tissues. Knockdown of GATA2 inhibited the growth, metastasis and stemness of cervical cancer cells and sensitized cervical cancer cells to radiation therapy. The inhibitory effect of TRIP4 knockdown on cervical cancer cells was rescued by GATA2 overexpression. Furthermore, TRIP4 could bind to the specific GATA2 promoter region, thereby activating its transcription. Clinical tissue microarray analysis indicated that the expression of TRIP4 and GATA2 was positively correlated, and high expression of both predicted a poor prognosis in cervical cancer patients. Our study demonstrated that GATA2 functions as the key downstream target of TRIP4 to promote cervical cancer progression and effective intervention of TRIP4/GATA2 signaling is expected to be developed as potential cervical cancer therapeutic strategy.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"132 ","pages":"Article 111778"},"PeriodicalIF":4.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, we reported that this signaling may be mediated by sequestered or internalized receptors. Here, we evaluated numerous mechanistic aspects of 5-HT_2B internalization and wash-resistant signaling and directly addressed the role of internalization. In the absence of an agonist, 5-HT_2B undergoes robust, constitutive internalization and recycling and is distributed at equilibrium between cell surface and intracellular compartments. Both constitutive and agonist-induced internalization are mediated through dynamin-dependent clathrin-mediated endocytosis. Constitutive internalization is unaffected by application of 5-HT_2B inverse agonists. We identified two, adjacent di-leucine motifs followed by a di-acidic cluster in the C-terminal tail of 5-HT_2B that are responsible for constitutive internalization of the receptor. Mutations in either of the leucine clusters or in the di-acidic motif partially inhibit constitutive 5-HT_2B internalization. A 5-HT_2B mutant in which both di-leucine clusters are disrupted, displays no constitutive internalization while undergoing robust agonist induced internalization. We demonstrate that wash-resistant signaling of ergots is mediated by persistently/irreversibly internalized signaling receptor complexes. Paradoxically, the potencies of ergot agonists are influenced by receptor internalization; measured potencies are reduced upon inhibition of receptor internalization, while potencies for 5-HT or other conventional agonists are unaffected. This phenomenon represents a novel mechanism by which agonist-dependent kinetics of receptor internalization and recycling affects not only the duration of receptor signaling, but also a basic pharmacological parameter such as agonist potency.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"131 ","pages":"Article 111769"},"PeriodicalIF":4.4,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While various aspects of myofibroblast physiology have been proposed as treatment targets, many of these approaches have shown limited long-term efficacy so far. However, ongoing research is uncovering new potential strategies for targeting myofibroblast activity, offering hope for more effective treatments in the future. The circadian molecular clock is a feature of almost every cell in the human body that dictates the rhythmic nature of various aspects of human physiology and behavior in response to changes in the surrounding environment. The dysregulation of these rhythms with aging is considered to be one of the underlying reasons behind the development of multiple aging-related chronic disorders, with fibrotic tissue scarring being a common pathological complication among the majority of them. Myofibroblast dysregulation due to skewed circadian clockwork might significantly contribute to fibrotic scar persistence. In the current review, we highlight the role of the circadian clock in the context of myofibroblast activation and deactivation and examine its dysregulation as a driver of fibrogenesis.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"131 ","pages":"Article 111774"},"PeriodicalIF":4.4,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, CAT inhibited osteoclast activity by enhancing the ubiquitination-mediated proteasomal degradation of HIF-1α, which reduced oxidative stress and subsequently suppressed osteoclast activity. The inhibitory effects of CAT on osteoclast function and oxidative stress were reversed by DMOG, a known inhibitor of HIF-1α degradation. Next, an in vivo mouse experiment using the Ovariectomized (OVX) model to induce osteoporosis indicated that CAT enhanced bone mass density, bone structure, and bone remodeling.
