CircRNA Interference Pathway: A New Target for Intervention in Different Stages of Heart Failure.

Cardio-cerebrovascular disease has seen a rapid rise in recent years, with Heart Failure (HF) -- a terminal stage of various cardiovascular diseases -- also on the rise. HF has a complex pathogenesis involving multiple factors, such as inflammation, fibrosis, and oxidative stress. Due to its unique reverse shear mechanism, HF exhibits distinct expression patterns across different diseases. CircRNA has been linked to conditions like cancer, diabetes, and osteoarthritis. This article briefly introduces the mechanisms of circRNA biogenesis and its associated biological functions, focusing on CircSLC8A1-1, CircRNA_000203, and others at the early stage of HF, CircRNA PAN3, CircRNA (ACR), and others during the progression of HF, and CircHIPK3, CircNfix, and others at the end stage of HF. These circRNAs play a participatory role in the exact mechanism. As a research method, circRNA can be utilized to study the pathogenesis of heart failure and serve as a target for drug discovery and development. Therefore, circRNA's ability to mark the disease at different stages has significant guiding implications for HF monitoring, treatment, and prognosis.
