研究室紹介
Professor Jin Sook Yoon's research lab focuses on the molecular mechanisms underlying thyroid-associated ophthalmopathy (Graves' orbitopathy), with a particular emphasis on inflammation, fibrosis, and adipogenesis in orbital fibroblasts. The lab investigates natural compounds such as quercetin for their therapeutic potential in modulating key inflammatory and fibrotic pathways, aiming to develop safe and effective medical treatments. Additionally, the lab explores ocular complications from cosmetic procedures, including filler-induced ocular ischemia, highlighting clinical and translational research in ophthalmic pathology. Their work bridges molecular biology, clinical ophthalmology, and pharmacology to address unmet needs in autoimmune and inflammatory eye diseases.

15BACKGROUND: Mutations in the SLC26A4 gene are responsible for Pendred syndrome and non-syndromic hearing loss (DFNB4). This study analysed non-synonymous SLC26A4 mutations newly identified in East Asians, as well as three common mutations in Caucasians, to characterise their molecular pathogenic mechanisms and to explore the possibility of rescuing their processing defects. METHODS: A total of 11 non-synonymous disease associated mutations were generated and their effects on protein processing a
The authors experienced a case with ocular ischemia with hypotony following injection of a dermal filler for augmentation rhinoplasty. Immediately after injection, the patient demonstrated a permanent visual loss with typical fundus features of central retinal artery occlusion. Multiple crusted ulcerative patches around the nose and left periorbit developed, and the left eye became severely inflamed, ophthalmoplegic, and hypotonic. Signs of anterior and posterior segment ischemia were observed i
Management of Graves' orbitopathy (GO) is challenging, as no reliable, specific, and safe medical therapeutic agents have yet been developed. We investigated the effect of quercetin in primary cultured orbital fibroblasts from GO, targeting pathways of inflammation, aberrant accumulation of extracellular matrix macromolecules, and adipose tissue expansion. Quercetin significantly attenuated intercellular adhesion molecule-1 (ICAM-1), interleukin (IL) -6, IL-8, and cyclooxygenase (COX) -2 mRNA ex
Cigarette smoking is known to aggravate Graves' orbitopathy (GO) severity by enhancing adipogenesis. We investigated the effect of quercetin, an antioxidant, on adipocyte differentiation induced by cigarette smoke extract (CSE) in primary cultured orbital fibroblasts (OFs) from GO patients. Freshly prepared CSE was added to the cells and H(2)O(2) was used as a positive control. Intracellular reactive oxygen species (ROS) generation and adipogenesis were measured. The expressions of proteins pero
Inhibition of proinflammatory cytokines by the natural product quercetin in both primary orbital fibroblasts and tissue culture provides the basis for its potential use as an anti-inflammatory agent in the treatment of GO.
Compared to paired normal eyelids, the eyelids with an ocular prosthesis exhibited significant signs of MGD. These results indicate that clinical assessment and management recommendations for MGD may benefit patients with prosthetic eyes, especially those with ocular discomfort.
An ocular prosthesis is a custom-made polymeric insert that can be placed in an anophthalmic socket for cosmetic rehabilitation of patients who have lost their eyes. The process of creating such a custom-made ocular prosthesis is time-consuming and labor-intensive because it involves artistic work that is carried out manually. This paper proposes a novel semi-automated method for fabricating customized ocular prostheses using three-dimensional (3D) printing and sublimation transfer printing. In
