I transferred to the Arispe Lab as a Staff Research Associate in May 2010 after 9 years of working for the Division of Laboratory Animal Medicine at UCLA. There I used to manage the Assisted Reproductive Technologies Lab for mice where I had the opportunity to work with Dr. Arispe and some of her amazing students. My current role in the lab involves a variety of tasks like getting new lab members set up with all of the required training, helping to maintain and update the animal use protocols, assisting lab members with various animal techniques, and cryopreserving mouse embryos just to name a few. My goals are to become proficient in ES cell culture and novel transgenic technologies to be able to provide additional support to our lab and contribute more to the scientific community as a whole while continuing to maintain my firm ideals in humane animal use in research. I feel blessed to have been given this incredible opportunity to work with Dr. Arispe and some of UCLA’s brightest that also share my compassion and respect for all life whether for our mice or fellow human beings.
I have been serving as administrative support to Dr. Arispe and her research lab since May 2017 and am delighted to encounter a bright group of scientists ready to collaborate and advance in their respective fields. I hope to make a positive contribution to The Arispe Lab, the Department of Molecular Cell and Development Biology, and the Molecular Biology Institute.
Undergrad/Master Institution: UPMC (Pierre and Marie Curie University) Paris, France
Graduate Institution: IRNS (Institute of Radioprotection and Nuclear Safety), under the tutoring of Dr. Fabien Milliat
I joined the Arispe lab in January 2016. During my PhD project I investigated the deleterious effect of endothelial PAI-1 in the pathogenesis of radiation-induced enteritis.
My goals during this post-doctoral training are to further use my expertise in radiobiology and radiopathology to address physiopathological processes in endothelial cells, while expanding my knowledge of vascular biology.

My research centers around the interplay of tumor cells with the vascular endothelium, and its role on metastasis and immune regulation in different types of cancer. I received my medical degree at the Charite-Humboldt University Berlin (Germany), where I developed a strong interest in the diagnosis and treatment of patients with solid tumors. To combine my scientific interests in vascular and cancer research, I joined the Arispe lab in August 2013. My current projects address two major tumor microenvironmental aspects and its therapeutic potential: a) the importance of blood vessels for immune response and immune escape of solid tumors. b) Mechanisms how cancer cells overcome the endothelial barrier during extravasation and distant metastasis. By applying tumor models in-vitro and in-vivo, as well as high throughput screenings and functional genomics, we are seeking new strategies to prevent cancer metastasis and tumor progression, with the ultimate goal of clinical translation. I am encouraged by the collaborative and interdisciplinary environment at UCLA and Los Angeles.

Graduate: Université Catholique de Louvain, Brussels, Belgium, Lab of Human Molecular Genetics, de Duve Institute
Postdoc Fellow: University of California, Los Angeles, CA, Molecular, Cell & Developmental Biology, Luisa Iruela-Arispe
I am currently a postdoctoral fellow in the Arispe lab. After graduating with a Masters degree in Immunology and Genetics from the University of Bayreuth in Germany, I carried out my PhD in Biomedical Sciences in the lab of Prof Miikka Vikkula at Université catholique de Louvain in Belgium. My research focused on the pathogenic effects of venous malformation-causative mutations in the tyrosine kinase receptor TIE2. I am very interested in the molecular bases of human disease, particularly (cardio-) vascular disease. To gain deeper insights into the cellular and molecular mechanisms underlying vascular development, I joined the Arispe lab in early 2015. My current project includes the characterization of vascular malformations and tumors and the study of novel pathways involved in vascular development. I am specifically interested in exploring the cross-talk of genes found to be associated with the emergence of vascular anomalies, in order to determine their function in maintenance of endothelial homeostasis.
Undergrad: University of California, Los Angeles, CA, Microbiology, Immunology and Molecular Genetics
Graduate: University of California, Los Angeles, CA
I joined the Aripse Lab in July 2016. As a graduate student my research focused on utilizing systems genetics approaches to identify novel contributors to cardiovascular disorders such as atherosclerosis and congestive heart failure. As postdoctoral fellow, my research focuses on understanding the function of the gene NOTCH3 in vascular smooth muscles and how NOTCH3 dysregulation contributes to development the familial stroke disorder Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL).

Residency: Cedars-Sinai, Obstetrics & Gynecology
I am a current Maternal Fetal Medicine fellow at UCLA having completed a residency in Obstetrics and Gynecology. My work in the Arispe lab will focus on the molecular mechanisms that underlie fetal congenital heart defects in both low-risk and high-risk pregnancies. Briefly, we hope to investigate how maternal diabetes alters genetic predisposition to fetal congenital heart diseases by characterizing epigenetics and transcriptome analysis in both a murine model and human umbilical cord model.

In the Arispe lab I am studying various factors that affect vascular endothelial homeostasis through the modulation of Notch signaling.
Graduate: University of California, MCIP Home Area
I am a graduate student in the Molecular, Cellular, and Integrative Physiology PhD program and I joined the Arispe Lab in the spring of 2019. I graduated from UC Irvine in 2016 with a degree in biomedical engineering and then became a post-baccalaureate fellow at the University of Missouri where I studied endothelial cell invasion and morphogenesis in the lab of Dr. George E Davis. I am currently working with Sanna to study how flow affects microtubule post-translational modifications in endothelial cells and am also getting the Arispe Lab’s own 3D printer up and running!
Undergrad: Mount Holyoke College, South Hadley, MA, Biochemistry
Graduate: University of California, Los Angeles, MBIDP (Cell and Developmental Biology Home Area)
I am a graduate student in the Molecular Biology Interdepartmental PhD Program and joined the lab in Summer 2017. I completed my undergraduate degree at Mount Holyoke College as a Biochemistry major where I studied the effects of DNA damage on nucleosome formation. In the Arispe lab my research focus is on the mechanobiology of vascular endothelium in the context of homeostasis and repair. Outside of lab you will find me taking dance classes or trying the best ice cream spots around the city!

NOTCH1 is a mechanosensor in adult arteries. Nature Communications. 8(1): 1620.
I am currently working under the mentorship of Dr. Milagros Romay who studies the function of the NOTCH3 gene in context of Cerebral Autosomal Dominant Arteriopathy with Subcortcial Infarcts and Leukoencephalopathy (CADASIL). While I’m new to the lab and have yet to determine the course of my undergraduate research career, it is my overarching goal to increase my understanding of genetically-linked diseases and their mechanisms at the molecular and cellular levels.
I am a second-year Physiological Science major working under the tutelage of Gloria Hernandez, predoctoral student at the Arispe Lab. We are currently working towards defining the intimal immune cell population and determining the biological relevance of immune cell accumulation in a non-diseased, aged mouse model.
I am a first-year MIMG major that joined the lab recently. Currently, I am working with Dr. Melanie Uebelhoer to learn basic lab techniques and learn about all of the science that the lab is working on.
My current project focuses on the effects of tension on regenerating vascular endothelial cells. I will specifically be looking at how in vitro cells respond to tension through Ibidi flow, and also be looking for the presence of multinucleated cells, using immunofluorescence and confocal microscopy. I will be planting cells on y-slides and observing areas of both high and low laminar flow to analyze differences in actomyosin contractility.
For this summer, I will be working with Gloria and exploring her project regarding intima-resident immune cells. Such cells surprisingly accumulate in the innermost layer of descending aortas in non-diseased adult mice. However, these immune cells are not found in the descending aortas of young mice. These findings raise questions about the significance of the intima-resident immune cells to cardiovascular disease as a result of aging. It is also worth noting that the intima contains a monolayer of endothelial cells, which again present a possible relationship with these immune cells. Our goal is to determine the functionality of the intima-resident immune cells and their relevance to cardiovascular disease and/or endothelial cells, if there is any.
I am currently studying the effects of cholesterol on endothelial homeostasis under my mentor, Hanna Sunshine. Atherosclerosis and heart disease are already known to be heavily affected by high cholesterol diets, but recent studies have shown that there is a genetic link between variations in Notch1 levels and atherosclerosis risk. Mainly through Western Blots, I aim to delve deeper into that link to better understand theses common diseases. By working on this project, I hope to apply my knowledge to further cardiovascular research in the future.
