OSAS, known for its association with arterial hypertension, coronary artery disease, and heart failure, appears to influence cardiovascular pathology partly through mediators like MRPL20‑AS1, which is demonstrably modulated in affected patients. This observation suggests that MRPL20‑AS1 may contribute to the cellular adaptations or maladaptations induced by OSAS‐associated hypoxic stress."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n \nEmerging evidence indicates that hypoxia, a central feature of OSAS, can trigger the altered expression of specific long non‑coding RNAs. In vitro experiments further support the notion that MRPL20‑AS1 is sensitive to hypoxic conditions, underscoring its potential role as a molecular mediator in the heart’s response to reduced oxygen levels. This finding links MRPL20‑AS1 not only to the pathophysiology of OSAS but also to broader cardiovascular disease mechanisms where oxygen deprivation is a key factor."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n \nOverall, the modulation of MRPL20‑AS1 by both OSAS and direct hypoxic stimuli emphasizes its potential importance in the intricate network of genetic regulation underlying cardiovascular diseases.
