Aging is a major factor in many cardiovascular diseases. The molecular factors that regulate age-related changes in cardiac physiology and contribute to the increased cardiovascular risk in the elderly are not fully understood. A study recently published in Nature suggests a specific role for microRNAs (miRNAs) in regulating cardiac aging and function, challenging the concept that aging is an inevitable process in the heart.

Background: Immune checkpoint inhibitors (ICIs) have been an important therapeutic advancement in the field of cancer medicine. Recent reports provided greater insights into the cardiovascular adverse events, which prohibited the use of ICIs. Cardiovascular adverse events occur in different forms, such as myocarditis and cardiomyopathy, myocardial fibrosis, heart failure and pericardial disease.

Reduced quantity and quality of stem cells in aged individuals hinders cardiac repair and regeneration after injury. We used young bone marrow (BM) stem cell antigen 1 (Sca-1) cells to reconstitute aged BM and rejuvenate the aged heart, and examined the underlying molecular mechanisms. BM Sca-1 or Sca-1 cells from young (2-3 months) or aged (18-19 months) GFP transgenic mice were transplanted into lethally irradiated aged mice to generate 4 groups of chimeras: young Sca-1 , young Sca-1 , old Sca-1 , and old Sca-1 .

Extracellular vesicles (EVs) are small-sized membrane-surrounded structures released from cells into the blood, which play important roles in regulating various biological processes. However, the role of EVs in Doxorubicin (DOX)-induced cardiomyocytes senescence remains elusive. In this study, we found that human serum EVs inhibited DOX-induced senescence in H9C2 cells, which was abolished by miR-34a mimic.

Background And Aims: Fetal and postnatal growth restriction cause a predisposition to cardiovascular disease (CVD) in adulthood. Telomeres are repetitive DNA-protein structures that protect chromosome ends, and the loss of these repeats (a reduction in telomere length) is associated with CVD. As exercise preserves telomere length and cardiovascular health, the aim of this study was to determine the effects of growth restriction and exercise training on cardiac telomere length and telomeric genes.
