The development of atherosclerosis begins with the accumulation of low-density lipoprotein (LDL) in the subendothelial space. As LDL becomes trapped in the arterial walls, reactive oxygen species (ROS) are generated, resulting in oxidative stress, impaired endothelial function, and oxidative modification of the retained LDL, forming oxidized LDL (ox-LDL). The oxidation of LDL to form ox-LDL is considered one of the most important factors in the development of atherosclerosis. Recently, there has been a growing interest in nanomaterials with enzyme-like characteristics called nanozymes in the field of biomedicine. The use of nanozymes has become increasingly popular because they offer solutions to the limitations associated with natural enzymes, including high costs, low stability, and challenging storage requirements. Nanozymes with anti-oxidative activities, such as catalase-, SOD-, and GPx-like nanozymes, have been extensively studied for various disease therapies, including atherosclerosis. Furthermore, nanozymes can be designed to have multiple enzyme-like activities. In this review, we aim to summarize studies that have used nanozymes as a therapeutic approach for the treatment of atherosclerosis. The results of this study have shown that nanozymes have a significant impact in reducing atherosclerotic plaques in <em>ApoE</em><sup><em>−/−</em></sup> mice. This effect is mainly achieved through ROS scavenging, which leads to the suppression of foam cell formation and inflammation.</div></div>","PeriodicalId":19916,"journal":{"name":"Pathology, research and practice","volume":"271 ","pages":"Article 156005"},"PeriodicalIF":2.9,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942946","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}

However, the biochemical mechanisms by which melatonin protects against reproductive damage from RF-EMR exposure are unknown.

Mechanistically, melatonin could inhibit ROS production and ferroptosis by stimulating the nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling pathway through its receptors (MT1/MT2).

Our results revealed that the combined asiaticoside and anti-PD-L1 treatment inhibited tumor growth by enhancing apoptosis and reducing tumor cell proliferation. The treatment activated T cells to increase the proportion of effector T cells in the spleen, evidenced by upregulated p-LCK and p-AKT levels.

NCOA4 is a key molecule mediating the selective autophagic degradation of ferritin. It affects ferroptosis by regulating intracellular free iron levels. NCOA4 expression is regulated by various factors, including cellular iron levels and oxidative stress. It was demonstrated that inhibition of NCOA4 can reduce iron-mediated cell death and mitigate liver damage, suggesting that NCOA4 may be a potential target for the prevention and treatment of liver diseases. Further in-depth studies of the molecular mechanism of NCOA4-mediated ferritinophagy and its relationship with iron-induced cell death can provide novel ideas for the diagnosis and treatment of liver diseases. The deficiency or abnormal expression of NCOA4 is closely associated with ferroptosis in a variety of liver diseases, including non-alcoholic fatty liver disease, alcoholic liver disease, drug-induced liver injury, and liver fibrosis.

However, a significant proportion of these patients fail to respond to BCG or recur after treatment.

Emerging evidence suggests that the tumor immune microenvironment influences the efficacy of BCG immunotherapy.

We provided evidence that USP46 was significantly elevated in hypertrophied mouse heart and in cell hypertrophy model, correlating with increased HIF-1α stability and activation of downstream glycolytic enzymes. We observed that knockdown of USP46 led to decreased HIF-1α levels and reduction in glycolysis rate, thereby attenuating myocardial hypertrophy in mice model of cardiac hypertrophy. Conversely, overexpression of USP46 enhanced the expression of HIF-1α, leading to increased glycolytic activity and exacerbation of cardiac hypertrophy. In vitro studies further demonstrated that USP46 enhances the stability of HIF-1α by binding to HIF-1α and reducing the ubiquitination of HIF-1α, thus promotes the transcriptional activity of HIF-1α, eventually facilitating the expression of metabolic genes associated with glycolysis. Metabolic profiling also confirmed that USP46/HIF-1α intervention significantly influenced lactate, pyruvate and ATP production in cardiac myocytes. Collectively, our findings suggest that USP46 plays a pivotal role in cardiac hypertrophy by modulating HIF-1α-dependent glycolytic processes.
