Cardiac fibrosis constitutes irreversible necrosis of the heart muscle as a consequence of different acute (myocardial infarction) or chronic (diabetes, hypertension, …) diseases but also due to genetic alterations or aging. Currently, there is no curative treatment that is able to prevent or attenuate this phenomenon that leads to progressive cardiac dysfunction and life-threatening outcomes. This review summarizes the different targets identified and the new strategies proposed to fight cardiac fibrosis. Future directions, including the use of exosomes or nanoparticles, will also be discussed.

Astragaloside IV (ASIV), the main active component of the traditional Chinese medicine HuangQi, exhibits ameliorating effects on myocardial fibrosis through unclear mechanisms. To investigate the effects of ASIV on Endothelial-to-mesenchymal transition (EndMT) in myocardial fibrosis, 10 ng/mL TGF-β1 was used to induce EndMT in human umbilical vein endothelial cells (HUVECs) and a 5 mg/kg/d subcutaneous injection of Isoproterenol (ISO) was used to induce myocardial fibrosis in mice . The drug affinity-responsive target stability (DARTS) was used to identify the target proteins of ASIV in endothelial cells.

The progression of renal fibrosis is difficult to reverse, and Poria cocos, one of the main components of Wenyang Zhenshuai Granules, has been shown to be crucial to the development of the epithelial-mesenchymal transition (EMT). This study aimed to examine the molecular mechanism by which Poricoic Acid A (PAA) inhibited the advancement of EMT in renal tubular epithelial (RTE) cells. The protein levels of sprouty RTK signaling antagonist 2 (SPRY2) extracellular regulated protein kinases (ERK), and p-ERK were measured.

Myocardial infarction (MI), induced by ischemia and hypoxia of the coronary arteries, presents as myocardial necrosis. Patients often experience intense, prolonged retrosternal pain that is unrelieved by rest or nitrate therapy and is frequently associated with high blood myocardial enzyme levels. Physical effort may exacerbate this anxiety, increasing the likelihood of life-threatening consequences such as arrhythmias, shock, or cardiac failure.

Background: Cystic fibrosis (CF) is a genetic disorder that remains underrecognized across Africa, where limited diagnostic capacity, low awareness, and competing health priorities contribute to delayed or missed diagnoses [1-4]. Although increasing data suggests CF is more prevalent than previously believed in Africa, survival remains poor [1]. These challenges do not only affect people with CF (pwCF) in Africa but also have implications for global understanding of the disease, particularly among populations historically excluded from CF research and treatment advances.

Cardiac fibrosis, especially in the infarct border zone, leads to decreased cardiac compliance, impaired systolic and diastolic function, resulting in heart failure. M6A methylation plays a role in fibrosis development. However, its underlying mechanism remains poorly understood.
