Abstract Exosomal circRNA serves a novel genetic information molecule, facilitating communication between tumor cells and microenvironmental cells, such as immune fibroblasts, other components, thereby regulating critical aspects of cancer progression including escape, angiogenesis, metabolism, drug resistance, proliferation metastasis. Interestingly, microenvironment have new findings in influencing escape mediated by the release exosomal circRNA. Given intrinsic stability, abundance, broad distribution circRNAs, they represent excellent diagnostic prognostic biomarkers for liquid biopsy. Moreover, artificially synthesized circRNAs may open up possibilities therapy, potentially bolstered nanoparticles or plant exosome delivery strategies. In this review, we summarize functions underlying mechanisms cell non-tumor cell-derived progression, with special focus on their roles immunity metabolism. Finally, examine potential application therapeutic targets, highlighting promise clinical use.

Tumorigenesis is a complex and dynamic process involving cell-cell cell-extracellular matrix (ECM) interactions that allow tumor cell growth, drug resistance metastasis. This review provides an updated summary of the role played by microenvironment (TME) components hypoxia in tumorigenesis, highlight various ways through which cells reprogram normal into phenotypes are pro-tumorigenic, including cancer associated- fibroblasts, -macrophages -endothelial cells. Tumor secrete numerous factors leading to transformation previously anti-tumorigenic environment pro-tumorigenic environment. Once formed, solid tumors continue interact with stromal cells, local infiltrating macrophages, mesenchymal stem endothelial pericytes, secreted ECM within (TME). The TME key response treatment outcome. Importantly, can initially be anti-tumorigenic, but over time promote tumorigenesis induce therapy resistance. To counter hypoxia, increased angiogenesis leads formation new vascular networks order actively sustain growth via supply oxygen nutrients, whilst removing metabolic waste. Angiogenic network aid metastatic dissemination. Successful novel development require identification therapeutic targeting cancer-associated- fibroblasts (CAFs) (CAMs), blocking ECM-receptor interactions, addition reprogramming immune success. Lastly, this highlights potential TME- hypoxia-centered therapies under investigation.

Angiogenesis is essential for tumour growth and metastasis. Antiangiogenic factor-targeting drugs have been approved as first line agents in a variety of oncology treatments. Clinical frequently target the VEGF signalling pathway during sprouting angiogenesis. Accumulating evidence suggests that tumours can evade antiangiogenic therapy through other angiogenesis mechanisms addition to vascular mechanism involving endothelial cells. These include (1) angiogenesis, (2) vasculogenic mimicry, (3) vessel intussusception, (4) co-option, (5) cancer stem cell-derived (6) bone marrow-derived Other non-sprouting angiogenic are not entirely dependent on pathway. In clinical practice, conversion closely related enhancement drug resistance, which often leads treatment failure.

This review explores the spatial temporal heterogeneity of TAMs within microenvironment (TME), highlighting their diverse subtypes, origins, functions. Advanced technologies such as single-cell sequencing multi-omics have elucidated intricate interactions between other TME components, revealing mechanisms behind recruitment, polarization, distribution. Key findings demonstrate that support vascularization, promote epithelial-mesenchymal transition (EMT), modulate extracellular matrix (ECM) remodeling, etc., thereby enhancing invasiveness metastasis. Understanding these complex dynamics offers new therapeutic targets for disrupting TAM-mediated pathways overcoming drug resistance. underscores potential targeting to develop innovative therapies, emphasizing need further research into characteristics functional roles TME.
