The proposed mechanisms of action are reduction of the size and fibrosis of infarct scars, improvement of myocardial viability, limitation of ventricular remodeling, improvement of ventricular compliance and paracrine effects.
13, 27, 35 The action of metformin is reduction of hepatic glucose output and reduction of fasting blood glucose levels.
The IABP's main mechanism of action is a reduction of afterload and increased diastolic coronary perfusion via electrocardiogram triggered counterpulsation.
Since insects can synthesize fatty acid de novo from acetate [ 47, 48], one possible mode of action of SCPIs' larvicidal activities is reduction in cholesterol uptake over time resulting in a deficiency in cholesterol that might lead to a high mortality rate in SCPI-treated Manduca larvae [ 34].
An important contributor to the reduction in contractility is reduction in the action potential-induced Ca transient {Zhong, 1997 5497}}, [ 35- 39].
Since high maternal viral load increases the likelihood of MTCT, one of the most effective mechanisms of action is simply the reduction of maternal HIV-1 RNA levels, which in turn lowers fetal prenatal and postnatal HIV exposure from maternal plasma, genital secretions, 24 and breast milk.
While the implied mechanism of action was a reduction in protein synthesis, it is also possible that increased lysosomal protein clearance plays a role in the hypoxic resistance of AARS mutants.
For Cd, DEBtox indicated that the most plausible mode of action was a reduction in energy assimilation.
The mechanism of action is through heart rate reduction, as this influences the viscoelastic properties of the arterial wall.
The overall effect of any of these actions is a reduction in the production of the protein product by the target gene.
