项目摘要
Project Summary
This K08 proposal will expedite the principal investigator’s progress towards his goal of becoming an
independent physician-scientist focused on increasing our understanding of pathogenic mechanisms of
pulmonary hypertension (PH) and developing innovative therapies to improve outcomes.
Candidate: Dr. Kel Vin Woo is a physician-scientist at Washington University School of Medicine (WUSM).
He completed a fellowship in Pediatric Cardiology and is developing expertise at the intersection of Fibroblast
Growth Factors (FGF) signaling and vascular biology under the mentorship of Dr. David Ornitz, a world authority
on FGF biology. Under Dr. Ornitz’s mentorship, the PI investigated how endothelial FGF signaling modulates
hypoxia-induced PH by mitigating endothelial-to-mesenchymal transition. He will leverage the skills gained
during his fellowship to further analyze FGF signaling in vascular smooth muscle cells and use adenovirus-
delivered endothelial FGF as a potential method of regulating vascular remodeling.
Career Development Plan: Dr. Woo will pursue this line of research with primary mentorship from Dr. Ornitz
and co-mentorship from Dr. Curiel (an expert in adenovirus vectorology). Additionally, a team of intramural and
extramural advisors include experts in PH, and vascular and pulmonary biology, and all have considerable
experience in nurturing independent investigators. WUSM provides a highly interactive environment with
excellent facilities, resources and opportunities. This 5-year plan builds on the PI’s prior experience and further
enriches his training, providing him with the tools needed for independence. It includes the following objectives:
(1) Master techniques in advanced mouse hemodynamic phenotyping; (2) Become proficient with adenovirus
engineering to improve PH outcomes using preclinical models of hypoxia-induced vascular remodeling; (3)
Disseminate research findings in diverse venues and actively establish productive collaborations.
Research Plan: The overall hypothesis of the proposal is that FGF signaling in lung endothelial and vascular
smooth muscle cells protects against hypoxia-induced PH. Specific Aim 1 will investigate how smooth muscle
cell FGF prevents pulmonary vascular remodeling. Aim 2 will interrogate how endothelial targeted adenovirus-
delivered FGF reduces hypoxia-induced vascular remodeling and PH severity. Upon completion of the proposed
research, Dr. Woo will be proficient in: (1) modulating intracellular pathways important for endothelial and smooth
muscle cell remodeling; (2) analyzing newly developed conditional knockout mice to ascertain the hemodynamic
effects on the lungs; and (3) developing approaches for gene delivery to lung endothelium as a potential therapy
for pulmonary vascular disease. These acquired skills will be readily applicable to other forms pulmonary
vascular disease and endothelial-smooth muscle interactions in vascular remodeling. Upon completion of the
proposed training, Dr. Woo will have acquired the necessary expertise to become an independent investigator
focused on reducing the burden of pulmonary diseases, in alignment with the NHLBI mission.

在不同的场所传播研究成果,积极建立富有成效的合作。
研究计划:该提案的总体假设是,肺内皮和血管中的FGF信号传导
平滑肌细胞保护免受缺氧诱导的PH。具体目标1将研究平滑肌如何
细胞FGF防止肺血管重构。目的2将探讨内皮靶向腺病毒-
递送的FGF降低缺氧诱导的血管重塑和PH严重程度。在完成拟议的
研究,吴博士将精通:(1)调节细胞内通路的重要内皮和平滑
肌细胞重塑;(2)分析新开发的条件性基因敲除小鼠以确定血流动力学
对肺的影响;和(3)开发将基因递送到肺内皮作为潜在治疗的方法
治疗肺血管疾病这些获得的技能将很容易适用于其他形式的肺部疾病
血管疾病和血管重塑中的内皮-平滑肌相互作用。完成后
通过拟议的培训,吴博士将获得成为独立调查员所需的专业知识
与NHLBI的使命保持一致,重点关注减轻肺部疾病的负担。
