Is fKBP12 a critical regulator of the heart rhythm and the cardiac voltage-gated sodium current in mice?
FKBP12 is a critical regulator of I(Na) and is important for cardiac arrhythmogenic physiology. FKPB12-mediated dysregulation of I(Na) may underlie clinical arrhythmias associated with FK506 administration.
IGF1 and IGF1R expression is associated with favorable clinicopathologic parameters and may involve early carcinogenesis of SICs. Target therapy for the IGF1R signaling pathway may not have a major therapeutic role in treating SIC.
