Cardiovascular disease (CVD), including restenosis, is a leading cause of morbidity and mortality in United States of America. Targeting Wnt-Frizzled (Fzd) signaling and Calcium-activated Potassium (KCa) Channels in deciphering the cellular/molecular mechanisms underlying restenosis in Coronary artery bypass graft (CABG) surgery patients is emerging as an attractive therapeutic strategy in management/prevention of CVD. My pilot study aimed to investigate the role of Fzd receptors and KCa channels in human Internal Mammary Artery and Saphenous Vein-derived Vascular Smooth Muscle Cells (VSMCs) from CABG surgery patients of North American ethnicity. Primary human VSMCs were isolated from IMAs and SVs derived from CABG surgery patients using Collagenase-IV enzymatic digestion method. The study was approved by the Institutional Review Board. RNA was extracted from hVSMCs (passages P3-P7) using Trizol method. Fzd and KCa mRNA transcripts were identified by semi-quantitative Reverse Transcriptase-Polymerase Chain Reaction followed by 2% Agarose gel electrophoresis. Whole cell patch clamp electrophysiological recordings were conducted for KCa currents. Mean age of CABG surgery patients (N=9) was 60.3 years (S.D±6.5 years). Receptor studies demonstrated the expression of Fzd1, Fzd2 and Fzd5 mRNA transcripts in IMA and SV-derived hVSMCs. However, BKCa (broad conductance), IKCa (intermediate conductance) and SKCa (small conductance) mRNA transcripts and KCa currents were not expressed/detected in hVSMCs; beta-actin was used as internal control. My preliminary data implicates the public health impact of Wnt-Frizzled signaling in restenosis. Future cell/molecular biology and electrophysiology-based studies targeting Fzd receptors and KCa channels may aid in the development of cost-effective predictive biomarkers for cardiovascular susceptible populations.
