: Targeting the Oxidative Activation of Protein Kinase G Iα: A Novel Therapeutic Approach for Hypertension.

: Show that mice unable to form the PKG disulfide bond (C42S KI) exhibit different blood pressure responses compared to wild-type (WT) mice. 23484.rar

: Measurement of blood pressure in conscious, freely moving mice using telemetric probe catheters . : Targeting the Oxidative Activation of Protein Kinase

: Data demonstrating that novel compounds targeting this site effectively lower blood pressure. 5. Discussion and Conclusion : Data demonstrating that novel compounds targeting this

: Protein Kinase G Iα (PKG Iα) is usually activated by cGMP, but it can also be activated by "oxidative stress" (specifically the formation of a disulfide bond at Cys42).

: Discuss the potential for developing a new class of antihypertensives that specifically target the oxidative state of the cardiovascular system.

: Summarize how the study identifies a specific redox-sensitive mechanism in PKG Iα that contributes to blood pressure regulation and how small molecules can target this to treat hypertension without the side effects of traditional vasodilators. 2. Introduction
