To further elucidate the relationship between copper transporters and cardiac copper efflux during chronic myocardial ischemia, a rhesus monkey model was established by performing the permanent ligation of the left anterior descending coronary artery. A dramatic decrease in copper concentration within ischemic cardiomyocytes was observed alongside declining cardiac function. Among major copper transporters, COMMD1 and ATP7B were significantly upregulated in the ischemic myocardium. COMMD1 was specifically localised in cardiomyocytes undergoing copper efflux, whereas increased ATP7B was restricted to cardiac fibroblasts. This indicates that elevated COMMD1 regulates copper efflux in cardiomyocytes during chronic myocardial ischemia, functioning independently of its interactions with P-type ATPase transporters. Given the discrepancy between RNA and protein levels of COMMD1 in ischemic myocardium, post-translational modification is likely responsible for regulating COMMD1 expression. We found that the copper-binding protein with E3 ubiquitin ligase activity, XIAP, augmented before the rise in COMMD1 expression within ischemic cardiomyocytes. Excessive XIAP specifically interacted with COMMD1 to enhance its protein levels under copper-deprivation conditions and vice versa. Overall, our findings reveal a positive feedback loop among XIAP, COMMD1 and copper, highlighting the intricate interplay between XIAP and COMMD1 in regulating copper efflux in cardiomyocytes.

Enhancer of Zeste Homologue 2 (EZH2), a histone methyltransferase, is essential for the suppression of gene expression. However, the role of EZH2 in astrocyte early morphogenesis has remained unclear. Using an astrocyte-specific Ezh2 knockout (cKO) mouse model, we examined the effects of EZH2 deletion on astrocyte morphogenesis, blood-brain barrier (BBB) integrity and neurodevelopment. Loss of EZH2 led to increased glial fibrillary acidic protein (GFAP) expression, altered astrocyte morphology and reduced coverage of astrocytic endfeet on blood vessels, compromising BBB integrity. Vascular abnormalities, characterised by increased vascular density and smaller vessel diameter, mirrored compensatory changes seen in moyamoya disease. RNA-sequencing and ChIP-seq identified Ddn as a key upregulated gene in Ezh2^cKO astrocytes, influencing cytoskeletal changes via the MAPK/ERK pathway. Behavioural analysis revealed autism-like traits, such as reduced vocalisations, without significant anxiety-like behaviour.

In the case of prepubertal girls, the clinical challenge is especially pronounced, as ovarian tissue cryopreservation-though promising-remains an experimental technique necessitating rigorous scientific validation to guarantee the developmental potential of preserved materials and facilitate broader clinical adoption. To address these knowledge gaps, while considering the ethical implications, we applied transcriptome and translatome sequencing to comprehensively profile the transcriptional and translational dynamics of oocyte maturation in adult and prepubertal goats. Our analyses uncovered a sequential transition in gene expression regulation, shifting from cytoplasmic processes to chromosome segregation during the maturation process. Comparative profiling between adult and prepubertal goat oocytes revealed critical regulatory factors essential for prepubertal oocyte maturation. These include genes involved in organelle function (GTPBP4 and TOMM7), spindle organisation (CKS2, CCP110, CKAP5 and ESCO1) and chromosome segregation (CENPE, CENPF, CENPN and SGO2). Functional validation through in vitro maturation experiments demonstrated that GTPBP4 significantly enhances the developmental competence of prepubertal goat oocytes. This enhancement occurs through mechanisms that promote cell cycle progression, organelle maturation and mRNA translation. These findings provide a detailed map of the molecular events underpinning goat oocyte maturation and offer new perspectives on the developmental strategies required for oocyte competence in prepubertal females. Translating these insights to humans, this research highlights potential fertility preservation strategies for prepubertal girls, such as ovarian tissue cryopreservation and transplantation, in vitro follicle culture, meiotic maturation and artificial ovary technologies. Moreover, the identified mechanisms have significant implications for improving reproductive efficiency in domestic animal breeding, bridging basic research and applied science.</p>","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70017"},"PeriodicalIF":5.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, we observed that after intestinal injury, intestinal bacteria and lipopolysaccharides (LPS) can enter the circulatory system, leading to a significant secondary increase in NETs production and the subsequent activation of a coagulation cascade. This phenomenon contributes to a pathological process known as the 'second strike' of NETs, which exaggerates intestinal damage and microcirculation disturbance. Selectively mitigating the detrimental effects associated with this second strike presents a promising therapeutic strategy. We developed an innovative conjugate of stroke-homing peptide (SHp) and DNase1 (SHp-DNase1) to enhance the stability of DNase in the bloodstream while selectively targeting NETs in thromboembolic events. The effects of SHp-DNase1 on blood flow, ischemia, and vascular leakage were evaluated in a mouse model using laser Doppler flowmetry and an in vivo imaging system. Levels of LPS and NETs were elevated in patients with IRI. Similarly, the expression of NETs and LPS was upregulated in mice with intestinal IRI. In vivo imaging revealed disturbances in intestinal microcirculation, accompanied by intestinal leakage, which were effectively reversed by the administration of SHp-DNase1. Almost all of the SHp-DNase1 localised to the gastrointestinal tract, demonstrating the effective targeting of DNase1 to the site of intestinal injury via SHp guidance. Furthermore, the combination of SHp-DNase1 and CRO significantly reduced the expression of ischemia-inducible factors, leading to a marked decrease in mortality in the mouse model. These findings suggest that intestinal LPS leakage correlated with NETs exacerbation plays a critical role in IRI. The combination of SHp-DNase1 and CRO is an effective treatment strategy by simultaneously controlling inflammation and addressing microcirculatory disorders induced by NETs in the therapy of IRI.</p>","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70010"},"PeriodicalIF":5.9,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143499218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
