AI Article Synopsis

  • Isoproterenol (ISO) causes major biochemical and tissue changes in the heart, resulting in oxidative stress and inflammation that worsen heart injury.
  • Administering ISO to rats mimics aspects of human heart disease, helping researchers understand disease mechanisms and test new treatments.
  • The chapter discusses how varying dosages and methods of ISO injection can be used to create different levels of heart injury for experimental purposes.

Article Abstract

Isoproterenol (ISO) administration produces significant biochemical and histological changes including oxidative stress, reactive oxygen species (ROS) overproduction, and inflammation that leads to aggravation of myocardial injury. Subcutaneous or intraperitoneal ISO injection into rats can replicate several features of human heart disease, making it a useful tool for comprehending the underlying mechanisms and evaluating potential therapeutic strategies. In the present chapter, we elaborate on how depending on the precise experimental goals and the intended level of severity, different dosages and regimens are employed to induce myocardial injury.

The highly conserved PIWI-interacting RNA CRAPIR antagonizes PA2G4-mediated NF110-NF45 disassembly to promote heart regeneration in mice.

Targeting the cardiomyocyte cell cycle is a promising strategy for heart repair following injury. Here, we identify a cardiac-regeneration-associated PIWI-interacting RNA (CRAPIR) as a regulator of cardiomyocyte proliferation. Genetic ablation or antagomir-mediated knockdown of CRAPIR in mice impairs cardiomyocyte proliferation and reduces heart regenerative potential.

R. China.

Diabetic cardiomyopathy (DCM) is one of the most lethal complications of diabetes and is induced by the overproduction of reactive oxygen species (ROS) in cardiomyocytes due to sustained high glucose levels, leading to cardiac oxidative damage and final sudden death. Drugs and antioxidants currently applied to the clinical therapy of DCM fail to scavenge ROS efficiently, resulting in compromised therapeutic efficacy. Herein, a nanocatalytic antioxidative therapeutic strategy is proposed for DCM treatment.
