Mitochondrial dysfunction fuels vascular inflammation and atherosclerosis. Mitochondrial calcium uptake 1 (MICU1) maintains mitochondrial Ca2+ homeostasis. However, the role of MICU1 in vascular inflammation and atherosclerosis remains unknown. Here, we report that endothelial MICU1 prevents vascular inflammation and atherosclerosis by maintaining mitochondrial homeostasis. We observed that vascular inflammation was aggravated in endothelial cell–specific Micu1 knockout mice (Micu1ECKO) and attenuated in endothelial cell–specific Micu1 transgenic mice (Micu1ECTg). Furthermore, hypercholesterolemic Micu1ECKO mice also showed accelerated development of atherosclerosis, while Micu1ECTg mice were protected against atherosclerosis. Mechanistically, MICU1 depletion increased mitochondrial Ca2+ influx, thereby decreasing the expression …

Rationale: Atherosclerotic cardiovascular disease (ASCVD) represents the predominant cause of mortality and morbidity globally. Given the established role of hypercholesterolemia as a significant risk factor for ASCVD, the discovery of new lipid-lowering medications is of paramount importance. ATP citrate lyase (ACLY) is a crucial enzyme in cellular metabolism, providing acetyl-CoA as the building block for the biosynthesis of fatty acids and cholesterol. Consequently, it has emerged as a promising drug target for innovative treatments of lipid metabolic disorders.

Methods: Virtual screening of a natural product library was performed to identify small-molecule ACLY inhibitors, leading to the discovery of isoginkgetin (ISOGK). …

Genetic Newborn Screening For Retinoblastoma: A Belgian Initiative Baby Detect, Daniel A Rodriguez, Alex Song, Anshul Bhatnagar, Christina Y Weng

Faculty, Staff and Students Publications

Baby Detect Project, started in September 2022, aimed to create a newborn screening test using targeted next-generation sequencing for all early-onset, treatable, and serious conditions. The elaborated gene panel covers 405 genes, associated with 165 genetic conditions, and includes RB1, linked to retinoblastoma, the only oncological disease tested for. Germline RB1 mutations concern around 50% of all retinoblastoma cases and 100% of the most severe, bilateral cases. Ninety percent of them occur de novo, which delays the diagnosis by about a year with subsequent loss of vision and sometimes the eye itself. Detecting children with germline RB1 mutation at …

Suppression Of Matrigel-Induced Choroidal Neovascularization By Aav Delivery Of A Novel Anti-Scg3 Antibody, Chengchi Huang, Avinash Kaur, Liyang Ji, Hong Tian, Keith A Webster, Wei Li

Faculty, Staff and Students Publications

Efforts to develop gene therapy for long-term treatment of neovascular disease are hampered by ongoing concerns that biologics against vascular endothelial growth factor (VEGF) inhibit both physiological and pathological angiogenesis and are therefore at elevated risk of adverse side effects. A potential solution is to develop disease-targeted gene therapy. Secretogranin III (Scg3), a unique disease-restricted angiogenic factor described by our group, contributes significantly to ocular neovascular disease. We have shown that Scg3 blockade with a monoclonal antibody Fab fragment (Fab) stringently inhibits pathological angiogenesis without affecting healthy vessels. Here we tested the therapeutic efficacy of adeno-associated virus (AAV)-anti-Scg3Fab to block …

As signalling organelles, cilia regulate their G protein-coupled receptor content by ectocytosis, a process requiring localised actin dynamics to alter membrane shape. Photoreceptor outer segments comprise an expanse of folded membranes (discs) at the tip of highly-specialised connecting cilia, into which photosensitive GPCRs are concentrated. Discs are shed and remade daily. Defects in this process, due to mutations, cause retinitis pigmentosa (RP). Whilst fundamental for vision, the mechanism of photoreceptor disc generation is poorly understood. Here, we show membrane deformation required for disc genesis is driven by dynamic actin changes in a process akin to ectocytosis. We show RPGR, a …

Immunologic Basis For Development Of Keratoconjunctivitis Sicca In Systemic Autoimmune Diseases: Role Of Innate Immune Sensors, Michael E Stern, Argyrios N Theofilopoulos, Philipp Steven, Jerry Y Niederkorn, Robert Fox, Margarita Calonge, Christof Scheid, Stephen C Pflugfelder

Faculty, Staff and Students Publications

The literature is filled with citations reporting an increased incidence of chronic dry eye disease, also known as keratoconjunctivitis sicca, in patients with systemic autoimmune diseases such as rheumatoid arthritis, Sjögren's Syndrome, systemic sclerosis and lupus. As the most environmentally exposed mucosal surface of the body, the conjunctiva constantly responds to environmental challenges which are typically self limited, but when persistent and unresolved may provoke pathogenic innate and adaptive immune reactions. Our understanding of the pathophysiological mechanisms by which systemic autoimmune diseases cause dry eye inducing ocular surface inflammation continues to evolve. Conjunctival immune tone responds to self or foreign …
