The Kelch-like ECH-associated protein 1-transcription factor NF-E2 p45-related factor 2 (KEAP1-NRF2) pathway plays a crucial role in maintaining redox homeostasis and regulating a multitude of biological processes such as inflammation, protein homeostasis, and metabolic homeostasis. In this paper, we present the findings of recent studies on the KEAP1-NRF2 pathway, which have revealed that it is aberrantly regulated and induces oxidative stress injury in a variety of diseases such as neurodegenerative diseases, cardiovascular diseases, metabolic diseases, respiratory diseases, digestive diseases, and cancer. Given this evidence, targeting KEAP1-NRF2 represents a highly promising avenue for developing therapeutic strategies for chronic diseases, and thus the development of appropriate therapeutic strategies based on the targeting of the NRF2 pathway has emerged as a significant area of research interest. This paper highlights an overview of current strategies to modulate KEAP1-NRF2, as well as recent advances in the use of natural compounds and traditional Chinese medicine, with a view to providing meaningful guidelines for drug discovery and development targeting KEAP1-NRF2. Additionally, it discusses the challenges associated with harnessing NRF2 as a therapeutic target.","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"67-96"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key metabolite of PAL, 8-Oxypalmatine (OPAL), shows favorable anti-inflammatory activity and better safety compared to PAL, though its mechanisms in ulcerative colitis (UC) are not fully understood. This study used a dextran sodium sulfate-induced colitis mouse model to explore OPAL's effects. The results indicated that OPAL provided superior therapeutic effects to those of PAL, alleviating colitis symptoms and reducing colon inflammation by modulating pro-inflammatory (tumor necrosis factor-α, interleukin-1β, and interleukin-6) and anti-inflammatory (transforming growth factor-β and interleukin-10) cytokines. Additionally, OPAL helped rebuild the mucus barrier and upregulated tight junction proteins, thereby restoring intestinal integrity. Notably, OPAL inhibited the M1 macrophages infiltration while promoting M2 macrophage distribution in the colon. Its role in fostering M2 polarization and modulating the inflammatory cytokine profile was further confirmed in vitro. Importantly, the anti-inflammatory effects were primarily linked to AMP-activated protein kinase activation, which subsequently inhibited the nuclear factor-kappa B pathway.

Modern research has confirmed that the active components of AM, including Astragalus polysaccharides, flavonoids (formononetin and calycosin), Astragalus saponins (Astragaloside I and Astragaloside III), and Astragalus nanovesicles, are effective in the treatment of colorectal cancer. The mechanisms mainly involve inducing apoptosis, inhibiting tumor angiogenesis and the metastasis of cancer cells, regulating the cell cycle and tumor microenvironment, and reversing drug resistance. Moreover, it offers a synergistic enhancement when used in combination with chemotherapy, radiotherapy, targeted therapy, or surgical treatment. AM also has great potential in treating colorectal cancer when combined with other herbs.

In this study, the correlation between fucosylation and cisplatin (cDDP) resistance in EOC cells was validated by gene expression profile analysis and lectin blot. We found that G-Rg6 derived from the American ginseng berry inhibits the cell viability and protein fucosylation of cDDP-resistant EOC cells. G-Rg6-induced G2/M-cell cycle arrest was proven to result from the autophagy of cDDP-resistant EOC cells. In addition, we observed that G-Rg6 initiates autophagy in cDDP-resistant EOC cells by inhibiting the GRB2-ERK1/2-mTOR axis, and that high concentration of G-Rg6 treatment leads to cell apoptosis. G-Rg6 also enhances cDDP uptake in A2780CP cells by promoting CTR1 expression and suppressing its core fucosylation. Therapies combining cDDP and G-Rg6 display higher efficacy in inhibiting the cDDP-resistant EOC cells in comparison with the sole application of cDDP, exhibiting strong potential for clinical application. G-Rg6 derived from the American ginseng berry can improve cDDP resistance in EOC cells via suppressing fucosylation and inducing autophagy, suggesting its potential in the adjuvant chemotherapy of EOC patients.","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"621-646"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143722803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous studies reported that electroacupuncture (EA) preconditioning exerted cardioprotective effects, the underlying mechanisms remain elusive. Thus, this study aimed to investigate the effects of EA preconditioning on oxidative stress and pyroptosis in MIRI rats, and explore the role of nuclear factor E2-associated factor 2 (Nrf2) throughout that process. A MIRI model was constructed by ligating the left anterior descending coronary artery for 30 min, followed by 4 h of reperfusion in rats. Prior to modeling, rats were subjected to EA at the Neiguan Point for three days. Furthermore, ML385, a Nrf2 inhibitor, was administered in order to examine the role of Nrf2 in regulating oxidative stress and pyroptosis following EA preconditioning. The results revealed that EA preconditioning improved left ventricular function after MIRI and reduced both the myocardial infarction area and cTnT levels. Meanwhile, EA preconditioning alleviated MIRI-induced oxidative stress and pyroptosis, as evidenced by the downregulation of ROS, MDA, NF-κB p65, caspase-1, IL-1β, and GSDMD-N, and the upregulation of SOD and HO-1. Mechanistically, EA up-regulated enhanced the expression of Nrf2. However, its cardioprotective effects and ability to attenuate oxidative stress and pyroptosis were suppressed by the inhibition of Nrf2. Taken together, our study indicated that EA preconditioning attenuated MIRI in rats by mitigating oxidative stress and pyroptosis, with Nrf2 playing a vital role in this protective mechanism.","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"337-352"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the primary site of involvement is the colon, UC can extend to encompass the entire rectum and colon. The causes and development mechanisms of UC are still not well understood; nonetheless, it is currently held that factors including environmental influences, genetic predispositions, intestinal mucosal integrity, gut microbiota composition, and immune dysregulation contribute to its development. Dysregulated immune responses are pivotal in the pathophysiology of UC, and these aberrant responses are considered key contributors to the disease onset. In patients with UC, immune cells become hyperactive and erroneously target normal intestinal tissue, resulting in inflammatory cascades and damage to the intestinal mucosa. The therapeutic strategies currently employed for UC include immunosuppressive agents such as aminosalicylates and corticosteroids. However, these treatments often prove costly and carry significant adverse effects - imposing a considerable burden on patients. Traditional Chinese Medicine (TCM) has attracted worldwide attention because of its multi-target approach, minimal side effects, cost-effectiveness, and favorable efficacy profiles. In this review, the ways in which TCM modulates inflammatory responses in the treatment of ulcerative colitis have been outlined. Research into TCM modalities for modulating inflammatory pathways in the treatment of UC, which has yielded promising advancements, including individual herbs, herbal formulations, and their derivatives, has been summarized. TCM has been utilized to treat UC and the immune system plays a key role in regulating intestinal homeostasis. It is imperative to facilitate large-scale evidence-based medical research and promote the clinical application of TCM in the management of UC.","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"435-473"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Targeted bile acid (BA) metabolomics and Western blotting demonstrated that GL improved DB-induced reduction in BA efflux by regulating FXR-mediated efflux transporters. Furthermore, analysis of 16S rDNA gene sequencing revealed that GL effectively restored the relative abundance of beneficial bacteria, reduced the relative abundance of harmful bacteria, and reinstated the structure of the intestinal flora. Additionally, correlation analyses between BA and intestinal flora indicated that Firmicutes, Bacteroidota, TDGA, DGA, UDGA, GDGA, THDGA, and HDGA could serve as major markers for DB-induced liver injury.

With ongoing research, however, it has been gradually determined that OA is not caused solely by mechanical injury or aging, but rather involves chronic low-grade inflammation, metabolic imbalances, dysfunctional adaptive immunity, and alterations in central pain processing centers. The main risk factors for OA include obesity, age, gender, genetics, and sports injuries. In recent years, extensive research on gut microbiota has revealed that gut dysbiosis is associated with some common risk factors for OA, and that it may intervene in its pathogenesis through both direct and indirect mechanisms. Therefore, gut flora imbalance as a pathogenic factor in OA has become a hotspot topic of research, with potential therapeutic connotations. In this paper, we review the role of the gut microbiota in the pathogenesis of OA, describe its relationship with common OA risk factors, and address candidate gut microbiota markers for OA diagnosis.

The mechanisms underlying ferroptosis in EMS primarily involve iron accumulation, lipid peroxidation, and loss of glutathione peroxidase 4 activity. These mechanisms confer resistance to ferroptosis within the ectopic tissues and facilitate cell survival and proliferation. Traditional Chinese medicine (TCM) has demonstrated therapeutic potential for modulating ferroptosis. Studies have shown that TCM monomers may regulate ferroptosis by modulating iron transport proteins and anti-oxidant defense mechanisms. TCM formulas employ distinct treatment strategies depending on the stage of EMS: in the early stages, they promote ferroptosis to control lesion growth, whereas in the later stages, they inhibit ferroptosis to reduce oxidative stress and inflammation in order to improve reproductive health and slow disease progression.
