摘要

The microRNA miR-126 supports endothelial cells and blood vessel integrity. Recent research has shown that it also serves as a key link between exercise and cancer. This article delves into how exercise affects the expression of miR-126, impacting cardiovascular well-being and metabolic control. The article also examines the various contributions of miR-126 in cancer, acting as both a suppressor and an enhancer depending on the particular context. Regular aerobic exercises, including HIIT, consistently increase levels of miR-126, leading to enhanced angiogenesis, endothelial repair, and improved vascular function through mechanisms involving VEGF, HIF-1α, and EPC mobilization. Resistance training affects similar pathways, but does not cause a significant change in miR-126 levels.

MiR-126 involves in cancer by suppressing tumor growth and controlling key pathways such as PI3K/Akt, ERK/MAPK, and EMT. Lower levels are associated with negative outcomes, later stages of the disease, and increased spread of different types of cancer like glioblastoma, CRC, ovarian, esophageal, gastric, and prostate cancer.

The relationship between exercise and cancer suggests a possible therapeutic approach, where the regulation of miR-126 through exercise could help improve vascular function and slow tumor growth. Further studies should focus on understanding the specific molecular pathways through which miR-126 connects these areas, leading to potential interventions that utilize its regulatory network to promote cardiovascular well-being and enhance cancer treatment.
