Twenty-four Sprague Dawley rats were excised at their dorsal neck and were addressed with either positive control, intrasite gel, or MEEA (250 and 500 mg/kg) for a two-week trial. Phytochemical, histopathological, and immunohistochemical assays were employed to depict wound healing potentials.

Viral infections can disrupt cellular iron metabolism, leading to inflammation and cancer. Ferritin, a key iron-binding protein, consists of ferritin heavy chain 1 (FTH1) and ferritin light chain (FTL) and helps regulate systemic iron balance, both implicated in various tumor developments. Epstein-Barr virus (EBV), the first oncogenic virus discovered in humans, can induce the development of EBV-associated gastric cancer (EBVaGC). However, the regulatory mechanisms and functions of FTH1 and FTL in EBVaGC are poorly understood. This study aimed to investigate how EBV regulates FTH1 and FTL and their roles in the development of EBVaGC. We show that EBV is able to remodel intracellular iron metabolism, affecting the expression of FTH1 and FTL. EBV-encoded LMP2A promotes the expression of FTH1 and FTL by up-regulating p62 and blocking the autophagy degradation pathway, thus participating in the occurrence and development of EBVaGC. Knocking down FTL inhibits cell migration and proliferation, and promotes apoptosis, whereas FTH1 knockdown has negligible effects on these cellular functions. Additionally, we found that ferritin enhanced the inflammatory state of gastric cancer cells.

To investigate the regulatory role of PANX1 in cardiomyocyte apoptosis following MI and elucidate its underlying molecular mechanisms. We conducted both in vivo and vitro studies. In vivo, we observed a significant elevation of PANX1 expression levels in post-MI mice, which facilitated macrophage recruitment and subsequently triggered upregulation of amphiregulin(AREG). In vitro, HL-1 cells exposure to hypoxia/reoxygenation (H/R) induced apoptosis, accompanying with the upregulation of PANX1, enhanced extracellular ATP release. And these alterations promoted the recruitment of RAW264.7 cells, subsequently elevating AREG levels. These effects were mitigated by the knockdown of PANX1. To confirm PANX1's role in MI hearts, AAV-9-PANX1-RNAi and negative control vectors were administered into the hearts of mice. Over 28 days post-MI, PANX1 knockdown significantly enhanced cardiac function and attenuated myocardial fibrosis. Our findings reveal that PANX1 plays a crucial role in facilitating a link between apoptotic cardiomyocyte and macrophage, contributing to modulate myocardial fibrosis and cardiac dysfunctional recovery post-MI via the AREG.

Quercetin (3,3',4',5,7-pentahydroxyflavone), a flavonoid with well-documented antioxidant and anti-inflammatory properties, has garnered significant attention in the field of skin regeneration. In addition, chitosan/alginate (C/A) wound dressings have been shown to create a conducive environment for wound healing, leveraging the antimicrobial and anti-inflammatory properties of chitosan, as well as the hydrogel and water-absorbing properties of alginate. Thus, the development of a biologic scaffold, such as quercetin-loaded C/A, may offer a promising alternative for diabetic wound treatment, providing a dermal structure that supports wound healing. In this study, a chitosan-alginate hydrogel was prepared and loaded with varying concentrations of quercetin (0.03%, 0.1%, and 0.3% w/v). Following in vitro evaluation using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), MTT assay, and swelling and degradation tests, the prepared dressings were applied to rats with diabetic wounds, and the resulting scars were analyzed histologically after a 2-week period. The FTIR spectra of the C/A hydrogels revealed characteristic absorption bands corresponding to specific functional groups, including hydroxyl (O-H), amine (N-H), and alkene (C=C) groups.

Cytochrome P450 2E1 (CYP2E1) plays a key role in metabolizing xenobiotics and toxic substances. The attempts to target CYP2E1 with inhibitors have yielded limited success in cancer treatment. Loss and gain-of-function experiments were performed to investigate the effects of CYP2E1 on HepG2 and Hepa 1-6 cells. Migration, invasion, intracellular reactive oxygen species (ROS) accumulation, and mitochondrial membrane potential were assessed in HepG2 cells. In vivo histopathological alterations were studied in DEN-administered rat models. Western blotting was performed to evaluate the mechanistic activation of the Wnt/β-catenin signaling pathway. In our pursuit, to elucidate the impact of CYP2E1 in carcinogenesis we revealed that in vitro, overexpression of CYP2E1 enhances the migration, invasion, increases the accumulation of intracellular ROS, and reduces the loss of mitochondrial membrane potential of HepG2 cells. In contrast, siRNA-mediated silencing of CYP2E1 produced the opposite effects. Histopathological analysis of liver sections showed pathological features such as clear cell foci, bile duct proliferation, inflammatory cell infiltration and nodule formation. In vitro and in vivo, mechanistic analysis demonstrated that CYP2E1 overexpression significantly activated the Wnt/β-catenin signaling pathway in HCC cells, as evidenced by increased protein levels of β-catenin, LEF, Cyclin D1 and survivin in immunoblot study. In vivo increased β catenin, LEF and GPC3 enhance the carcinogenicity as revealed in immunohistochemistry results. Altogether, the above findings indicates that CYP2E1 has a pivotal role in the pathogenesis and progression of HCC identifying it as a potential target for liver cancer treatment.</p>","PeriodicalId":650,"journal":{"name":"Journal of Molecular Histology","volume":"56 4","pages":"218"},"PeriodicalIF":2.9,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144590181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
