Hydrogen Sulfide Therapy Suppresses Cofilin-2 and Attenuates Ischemic Heart Failure in a Mouse Model of Myocardial Infarction

Hydrogen sulfide (H2S) protects against ischemic and inflammatory injury following myocardial ischemia via induction of microRNA (miR)-21. We sought to determine whether H2S attenuates ischemic heart failure with reduced ejection fraction (HFrEF) and interrogate the role of cofilin-2, a target of miR-21, in this protective process. Adult male mice underwent myocardial infarction (MI) by coronary artery ligation after baseline echocardiography. Following MI, mice were treated with Na2S (100 μg/kg/day; intraperitoneal [IP]) or saline up to 28 days. End-diastolic pressure, measured by Millar catheter, was significantly increased (P < .05 vs sham) at 3 days post-MI in the saline group, which was attenuated with Na2S. Left ventricular (LV) fractional shortening decreased significantly at 28 days post-MI in the saline group but was preserved with Na2S and LV infarct scar size was smaller in Na2S group as compared to control. Apoptotic signaling, measured by Bcl-2/Bax ratio, was significantly increased in the saline group but was mitigated with Na2S. Survival rate was 2-fold higher in Na2S group compared to saline control (P < .05).

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
