The Warburg effect plays a significant role in the advancement of cancer, and focusing on the suppression of aerobic glycolysis could offer a promising strategy for anti-cancer treatment. Various glycolysis processes are associated with tumor metastasis, primarily involving non-coding RNA (ncRNAs), signaling pathways, transcription factors, and more. Various categories of noncoding RNAs, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), have shown promise in influencing glucose metabolism associated with the spread of tumors. Additionally, circular RNAs (circRNAs) and long non-coding RNAs (lncRNAs) predominantly act as competitive endogenous RNAs (ceRNAs) by sequestering microRNAs, thereby modulating the expression of target genes and exerting significant influence on the metabolic processes of cancerous cells. Furthermore, the process of tumor metastasis through glycolysis also encompasses various signaling pathways (such as PI3K/AKT, HIF, Wnt/β- Catenin, and ERK, among others) and transcription factors. This article delineates the primary mechanisms through which non-coding RNAs, signaling pathways, and transcription factors contribute to glycolysis in tumor metastasis. It also investigates the potential use of these factors as prognostic markers and targets for cancer treatment. The manuscript also explores the innovative applications of specific traditional Chinese medicine and clinical Western medications in inhibiting tumor spread through glycolysis mechanisms, offering potential as new candidates for anti-cancer drugs.</p>","PeriodicalId":93964,"journal":{"name":"Current molecular pharmacology","volume":" ","pages":"e18761429308361"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142121404","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}

Multiple molecular mechanisms, including inflammation, reactive oxygen species (ROS) generation, fibrotic reactions, and angiogenesis, are involved in the pathogenesis of endometriosis; however, the exact cause of this disorder still remains a matter of discussion. Recently, it has been shown that the local renin-angiotensin system (RAS) has been expressed in different tissues, like the gynecological tract, and alterations in its expression are associated with multiple pathological conditions like endometriosis. Angiotensin II (Ang II), as a main peptide of the RAS through angiotensin type 1 receptor (AT1R), upregulates signal transduction pathways such as nuclear factor kappa B (NF-κB), mitogen activation protein kinase (MAPK), and transforming growth factor beta (TGF-β) to promote inflammation, oxidative stress, and fibrogenesis. Angiotensin receptor blockers (ARBs) control high blood pressure, which is increased by excessive AT1R activity. Recently, it has been recognized that ARBs have tissue protective effects because of their anti-inflammatory and antifibrotic effects.
