Modulation of potassium channel gating by external divalent cations
We have examined the actions of Zn2+ ions on Shaker K channels. We found that low (100 microM) concentrations of Zn2+ produced a substantial (approximately three-fold) slowing of the kinetics of macroscopic activation and inactivation. Channel deactivation was much less affected. These results were obtained in the presence of 5 mM Mg2+ and 4 mM Ca2+ in the external solution and so are unlikely ...
متن کاملAre Heart Muscle Irisin Levels and FNDC5 Gene Expression Regulated by Endurance and Resistance Exercises?
Background. Irisin is the result of the proteolysis of fibronectin type III domain-containing protein 5, the levels of which are determined by physical activity. Objective(s). This study aims to identify changes in FNDC5 gene expression and the heart muscle irisin levels in male rats following 8 weeks resistance and endurance training. Methods. Fifteen male rats (10-12 weeks old and 331.8&plu...
متن کاملmRNA levels Are Regulated by Muscle Activity
Denervation of adult skeletal muscle results in increased sensitivity to acetylcholine in extrajunctional regions of the muscle fiber. This increase in acetylcholine sensitivity is accompanied by a large increase in the level of mRNAs coding for the a-, f3-, Y-, and S-subunits of the acetylcholine receptor. To determine whether muscle activity is sufficient to regulate expression of extrajuncti...
متن کاملPlant defense genes are regulated by ethylene.
One of the earliest detectable events during plant-pathogen interaction is a rapid increase in ethylene biosynthesis. This gaseous plant stress hormone may be a signal for plants to activate defense mechanisms against invading pathogens such as bacteria, fungi, and viruses. The effect of ethylene on four plant genes involved in three separate plant defense response pathways was examined; these ...
متن کاملMacrophage Functions Are Regulated by Murine
Introduction Because of their paternal antigens, the fetus and placenta may be considered an allograft in the maternal host. Understanding the mechanisms which prevent maternal immunological rejection of the fetus remains a fundamental unsolved problem in immunology. We have previously reported that macrophages are inhibited by maternal decidual stromal cells residing at the maternal-fetal inte...
