Silencing mutations in JAG1 gene may play crucial roles in the pathogenesis of Tetralogy of Fallot.

JAG1 gene through Notch signaling is implicated in cell fate decisions in early cardiac development, and mutations in several proteins in the pathway have been involved in various disorders. Tetralogy of Fallot (TOF) is the most frequent form of complicated congenital heart disease. The abnormality of TOF begins through the first eight weeks of fetal growth and is confused with ventricular septal defects, obstruction to right ventricular outflow tract, aortic dextroposition, and right ventricular hypertrophy.

Serum Levels of IL-6, IL-8, TNF-α, and TGF-β in Chronic HBV-Infected Patients: Effect of Depression and Anxiety.

Objective: To assess the effects of depression and anxiety on serum cytokine levels in patients with chronic hepatitis B (CHB) infection.

Methods: In this cross-sectional study, 60 healthy control individuals and 60 patients with CHB participated after filling out standard questionnaires. We examined their serum interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, and TGF-β levels using enzyme-linked immunosorbent assay (ELISA) techniques.
