Research Summary

Center/Research Area Affiliations


Dr. Saint-Geniez joined the Schepens Eye Research Institute of Mass. Eye and Ear in 2002 to complete her postdoctoral training in the laboratory of Dr. Patricia D’Amore. During her fellowship, she characterized the role of VEGF in ocular development and the maintenance of retinal homeostasis. Her current research program focuses on the characterization of novel molecular pathways involved in various retinal degenerative diseases. With support from the National Institutes of Health, the Brightfocus Foundation, the Lions Foundation of Massachusetts, and Research to Prevent Blindness, she is investigating the underlying pathogenic roles of metabolic dysfunction and oxidative damage in photoreceptors and retinal pigment epithelium, as well as the therapeutic benefits of novel metabolic regulators using multidisciplinary approaches, including mouse model generation and molecular and metabolic biology. In 2015, Dr. Saint-Geniez, received the Cotran Early Career Investigator Award 2016 (ASIP) for her contribution to ocular research.

Her Story

Early Research

Dr. Saint-Geniez is a research scientist specializing in ophthalmology. She conducted her graduate studies at the University of Toulouse III, France, and was awarded a competitive Training Grant from the French Associate and Amblyopia (AFAU). Her thesis project focused on the determination of the functions of a new G protein-coupled receptor, msr/apj, and its ligand, Apelin, during physiological and pathological angiogenesis.

In 2002, Dr. Saint-Geniez joined the Schepens Eye Research Institute of Mass. Eye and Ear to begin a postdoctoral fellowship in Dr. Patricia D’Amore's laboratory. Her research focused on the role of VEGF in ocular development and retina function and was funded by a competitive fellowship grant from the Schepens Eye Research Institute of Mass. Eye and Ear (2003-2004).

She demonstrated that VEGF was expressed by various cells during ocular organogenesis and identified a new autocrine VEGF pathway involved in lens fiber differentiation (IOVS 2009).

She also determined that VEGF is a survival factor for adult choroidal vessels (IOVS 2006) and showed that endogenous VEGF is required for the maintenance of the visual function. This work was published in Plos One (Nov 3, 2008) and featured in the November 2008 issue of Harvard Medical School Focus journal.

She used transgenic models to determine the function of RPE-derived VEGF in the maintenance of choroidal vessels and revealed that alteration of VEGF signaling in adult RPE leads to age-dependent anomalies of the back of the eye similar to geographic age-related macular degeneration (or dry AMD) confirming the hypothesis that endogenous VEGF is required for a healthy RPE-choroid complex (PNAS 2009). This work was featured in the February 2010 issue of the EyeNet Magazine, which is published by the American Academy of Ophthalmology.

Translational Research

As an independent investigator, Dr. Saint-Geniez is expanding her scientific interest to new translational research. Notably, she received the NIH Director’s New Innovator Award for the development of new porous polymeric scaffolds for ocular tissue bioengineering. Currently, she is combining biomaterial engineering and stem cells technology to design new methodology for the effective transplantation of RPE for the treatment of AMD (J Mater Sci Mater Med 2013) In addition, Dr. Saint-Geniez is characterizing the role of new metabolic genes in pathological neovascularization of the retina. In collaboration with Dr. Arany (Beth Israel Deaconess Medical Center, Boston), she recently demonstrated that PGC-1a—a transcriptional coactivator that plays a central role in the regulation of cellular metabolism—regulates VEGFA in the retina and is required for normal vessel development and for pathologic neovascularization (AJP 2013). Her laboratory is now investigating the role of PGC-1 isoforms in photoreceptor and RPE and their contribution to retinal diseases such as retinal degeneration and AMD.


PGC-1 Co-activators in Photoreceptor Development and Survival

This study aims to determine the function of the transcription factors PCG1s in photoreceptor development and retinal degenerative diseases.

Role of PGC-1 isoforms in RPE Function and Oxidative Stress: Implications for AMD

This project aims to characterize the functions of PGC-1 isoforms in the metabolic and degenerative processes of the retinal pigmented epithelium.

Roles of Metabolism, Oxidative Stress and PGC-1 Isoforms in Retinal Detachment

This study aims to characterize the metabolic alterations associated with retinal detachment (RD) and determine the function of PGC-1s in RD-mediated retinal degeneration.

Patient-Specific Modeling of Oxygen Distribution for Predicting Retinal Degeneration

This project aims to develop a patient-specific computational model for predicting retinal degeneration due to hypoxia or hyperoxia in the retina.

Mechanobiology of RPE Cells

The goal of this study is to determine the impact of substrate stiffness on RPE biology and to characterize the role of substrate stiffening secondary to aging and/or pathology in the pathogenesis of age-dependent macular degeneration.
