Recurrent oncogenic ZC3H18 mutations stabilize endogenous retroviral RNA.

Endogenous retroviral (ERV) RNA is highly expressed in cancer, although the molecular causes and consequences remain unknown. We found that ZC3H18 (Z18), a component of multiple nuclear RNA surveillance complexes, has recurrent truncating mutations in cancer. We show that Z18 mutations are oncogenic and that Z18 plays an evolutionarily conserved role in nuclear RNA surveillance of ERV RNA.

Lupeol Attenuates Palmitate-Induced Hypertrophy in 3T3-L1 Adipocytes.

Obesity is characterized by the enlargement of adipose tissue due to an increased calorie intake exceeding the body's energy expenditure. Changes in the size of adipose tissue can lead to harmful consequences, with excessive fat accumulation resulting in adipocyte hypertrophy and promoting metabolic dysfunction. These adiposity-associated pathologies can be influenced by dietary components and their potential health benefits.

Empagliflozin in diabetic cardiomyopathy: elucidating mechanisms, therapeutic potentials, and future directions.

Diabetic cardiomyopathy (DCM) represents a significant health burden, exacerbated by the global increase in type 2 diabetes mellitus (T2DM). This condition contributes substantially to the morbidity and mortality associated with diabetes, primarily through myocardial dysfunction independent of coronary artery disease. Current treatment strategies focus on managing symptoms rather than targeting the underlying pathophysiological mechanisms, highlighting a critical need for specific therapeutic interventions.

Accuracy of Intraoperative Transesophageal Echocardiographic Doppler Parameters in Assessing the Right Ventricular Diastolic Function After Repair of Tetralogy of Fallot in Pediatric Patients.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.

Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.
