Activating transcription factor 3 (ATF3), a representative stress-responsive protein, plays pleiotropic roles in various biological processes. Over the past decade, studies have described not only the general role of ATF3 in tumor metabolism but also the complexity of ATF3 expression regulation and its associated modifications, including phosphorylation, ubiquitination, SUMOylation, and NEDDylation. Interestingly, beyond being a transcription factor, ATF3 can act as a modifier to control the ubiquitination of target molecules, such as p53, to exert its function in tumors. These advances in uncovering ATF3 biological function have yielded new insights into the cellular stress response during tumor development and will be instrumental in developing novel interventions. In this review, we update the role of ATF3 as a nexus in amino acid metabolism, lipid metabolism, glycometabolism, and other metabolic pathways in tumors; delineate the underlying mechanisms involving DNA level regulation, epigenetic regulation, and post-translational modifications of ATF3; and summarize the progression of tumor mono/combination therapies related to ATF3. In particular, we discuss the challenges that need to be addressed to provide a new conceptual framework for further understanding the potential therapeutic value of ATF3 in ongoing clinical trials.</div></div>","PeriodicalId":19918,"journal":{"name":"Pharmacological research","volume":"214 ","pages":"Article 107666"},"PeriodicalIF":9.1,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Later, CB2r was found in the brain not only under pathological conditions but also under basal conditions. It is now known that this receptor is expressed in different brain regions and different cell types, including neurons and microglia. Experimental studies have provided robust evidence that CB2r is involved in the modulation of the immune system, neuroinflammation, oxidative stress and neuroprotection. Besides, CB2r mediated the response to stress, anxiety, and depression. Also, CB2r plays a relevant role in modulating the reinforcing properties of different drugs of abuse, including alcohol, nicotine and cocaine. In this review, we summarize the cumulative knowledge regarding the immunomodulatory, anti-inflammatory, antioxidant, and neuroprotective properties of CB2r against the development of neurodegenerative diseases. Indeed, we cover the anxiolytic and antidepressant potential of CB2r, which raises the therapeutic interest of this receptor in different psychiatric diseases associated with anxiety and depression.

This study aims to investigate whether the gut microbiota and its metabolites can serve as gut-brain signaling molecules and explores how the gut microbiota affects stress sensitivity. Here, we showed that gut microbiome-derived indole-3-carboxaldehyde (I3C) can act as a gut-brain signaling molecule that links tryptophan metabolism by gut microbes to stress vulnerability in the host.

Furthermore, supplementation with I3C and the representative I3C-producing strain, <em>Lactobacillus reuteri</em>, was shown to alleviate depression-like behaviors induced by chronic stress. Further research confirms that I3C can inhibit neuroinflammation and promote hippocampal neurogenesis through the aryl hydrocarbon receptors (AhR) signal pathway, thereby mitigating the host's susceptibility to stress.
