Tumor Microenvironment and Metastasis

The tumor microenvironment (TME) plays a pivotal role in the progression and metastasis of lung cancer. Recent research has identified nicotinamide N-methyltransferase (NNMT) as a negative regulator of cancer-associated fibroblasts (CAFs) in lung adenocarcinoma, suggesting that metabolic and epigenetic regulation within the TME can influence metastatic potential (ref: Wang doi.org/10.1002/cac2.12633/). Additionally, exercise has been shown to exert anticancer effects, with a study identifying muscle-derived extracellular vesicle-associated miR-29a-3p as a key mediator in enhancing antitumoral immune responses (ref: Plaza-Florido doi.org/10.1016/j.trecan.2024.11.006/). The interplay between the TME and immune cells is critical, as evidenced by findings that higher peripheral T cell diversity correlates with better responses to dual immune checkpoint inhibitor therapy (ref: Altan doi.org/10.1136/jitc-2024-008950/). This highlights the potential for leveraging TME characteristics to predict treatment responses and tailor therapies accordingly. Overall, understanding the TME's influence on lung cancer progression and treatment response is essential for developing more effective therapeutic strategies.
