Research Description

Identification of Factors and Mechanisms that Regulate the Stability of Late Stage Atherosclerotic Lesions and the Probability of Thromboembolic Events Including a Heart Attack or Stroke
Atherothrombosis, resulting from rupture or erosion of unstable atherosclerotic plaques, is the leading cause of death worldwide. However, the mechanisms that regulate the stability of late stage atherosclerotic lesions remain poorly understood. The general dogma based on extensive human histopathology studies is that: 1) plaque composition not size is a critical determinant of late stage lesion stability and the probability of rupture or erosion and a possible heart attack or stroke; 2) plaques containing a large necrotic core, a thin fibrous cap, and large numbers of CD68+ cells relative to Acta2+ cells [presumed to be macrophages (MФ) and smooth muscle cells (SMC) respectively] are more prone to rupture or erosion; and 3) the primary role of the SMC is athero-protective by virtue of them being the primary cell type responsible for formation of a protective fibrous cap.
However, several recent Nature Medicine studies1, 2 by our lab involving simultaneous SMC lineage tracing and SMC-specific knockout (KO) of the stem cell pluripotency genes Oct4 or Klf4, have provided compelling evidence challenging this dogma and showing that SMC play a much greater role in lesion pathogenesis than has been generally appreciated [see our recent review3]. For example, we showed that >80% of SMC-derived cells within advanced lesions of ApoE-/- mice fed a Western diet (WD) for 18 weeks lacked detectable expression of SMC markers such as Acta2 typically used to identify them meaning that previous studies in the field have grossly under-estimated the number of SMC-derived cells within advanced lesions. Moreover, >30% of cells previously identified as MФ within advanced mouse brachiocephalic artery (BCA) lesions and human advanced coronary artery lesions were found to be of SMC not myeloid origin meaning that previous estimates of SMC/ MФ ratios are highly inaccurate. Even more importantly, we found that SMC can play either a beneficial or detrimental role in lesion pathogenesis depending on the nature of their phenotypic/functional transitions. For example, Klf4-dependent transitions, including formation of SMC-derived MФ-marker+ foam cells1 exacerbated lesion pathogenesis whereas Oct4-dependent transitions2 were atheroprotective including being critical for migration and investment of SMC into a protective fibrous cap. Indeed, remarkably, results of RNAseq and Oct4/Klf4 CHIPseq analyses of advanced brachiocephalic lesions from SMC Klf4 versus SMC Oct4 knockout mice showed virtually completely opposite genomic signatures. Taken together, results show that SMC play an absolutely critical, even dominant role, in late stage lesion pathogenesis in that conditional loss of a single gene in SMC can completely alter lesion pathogenesis [see our recent review3].
A major focus of our current studies is to identify factors, mechanisms, and potential therapeutic targets that can promote beneficial, and/or inhibit detrimental SMC phenotypic transitions within advanced lesions and thereby promote increased plaque stability. In addition, we are determining if mutations or gene polymorphisms that are linked to increased cardiovascular disease in humans may function, at least in part, by promoting detrimental changes in SMC phenotype and their associated functions. Finally, we have initiated additional studies investigating the potential role of SMC and pericyte phenotypic transitions in the pathogenesis of microvascular disease associated with Type II diabetes/metabolic disease, and in regulation of tumor cell growth and metastasis. The latter studies, which were published in Nature Medicine4 and done in collaboration with Dr. Kaplanâs lab at NIH, showed that highly metastatic tumor cells secrete factors that circulate in blood and induce Klf4-dependent reprogramming of SMC and pericytes within metastatic niches that make them permissive for tumor cell invasion and survival. Remarkably, we found that SMC-pericyte specific knockout of the stem cell pluripotency gene Klf4 dramatically reduced tumor metastasis by >70%.

Personal Statement

Research interests and thematic emphasis
Dr. Owens research is focused on the molecular regulation of differentiation of vascular smooth muscle cells (SMC) during development, and how transitions in the differentiated state of these cells, or so-called SMC phenotypic switching contributes to the pathogenesis of major human diseases including atherosclerosis, cancer, hypertension, and aneurysms which are the leading causes of death worldwide. A major focus of current studies is to identify factors, mechanisms, and potential therapeutic targets that can promote beneficial, and/or inhibit detrimental SMC phenotypic transitions and associated functional changes within advanced lesions and thereby promote increased plaque stability. In addition, we are determining if mutations or gene polymorphisms that are linked to increased atherosclerotic disease in humans may function, at least in part, by promoting detrimental changes in SMC phenotype and their associated functions. We have also initiated new studies aimed at defining the role of SMC and pericyte phenotypic transitions in the pathogenesis of microvascular disease associated with Type II diabetes/metabolic disease, and in regulation of tumor cell growth and metastasis. Finally, the lab is studying the role of epigenetic mechanisms (e.g. histone modifications and chromatin structure) and embryonic stem cell (ESC) [and induced pluripotential stem (iPS) cell] pluripotency gene networks in regulating transitions in SMC phenotype during development of atherosclerosis as well as in tissue repair and regeneration. Remarkably, using novel mouse model systems developed by his group, they have evidence showing that perivascular cells including SMC and pericytes represent a source of multi-potential MSC-like cells that play a key role in tissue regeneration and repair, and that phenotypic transitions of these cells are mediated via the ESC pluripotency genes Oct4 and Klf4.
