研究室紹介
Professor Sae-Hee Park's research lab focuses on endocrine and metabolic disorders, with a strong emphasis on pituitary and thyroid diseases, including acromegaly, Graves' disease, and differentiated thyroid carcinoma. The lab investigates the impact of biological factors such as age and sex on surgical and clinical outcomes, explores gut hormone regulation through novel molecular pathways like OR51E1 in L cells, and examines metabolic signatures and biomarkers in autoimmune thyroid diseases. Additionally, the lab contributes to plant biotechnology by studying gene regulation and ascorbate metabolism in tomato fruit ripening, highlighting translational research across human health and agricultural biotechnology.

15Context: Sex and age are factors conferring resistance to medical treatment in patients with acromegaly. However, their impact on outcomes of transsphenoidal-selective adenomectomy (TSA) has not been evaluated. Objective: To analyze age- and sex-related differences concerning surgical outcomes of growth hormone (GH)-secreting pituitary adenomas. Design: Retrospective. Setting: Single-center tertiary hospital. Participants: Patients with acromegaly (n = 463) who underwent TSA between January 2000
Understanding how comorbidities contribute to death in cancer patients is becoming an important topic. The present study assessed the role of comorbidities in overall mortality and causes of death in patients with differentiated thyroid carcinoma (DTC). This retrospective cohort study included 2070 patients who underwent thyroidectomy for DTC at a single institution between 2002 and 2005. Probabilities of overall, DTC-specific and other-cause death were examined according to the number of comorb
Glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), produced by intestinal enteroendocrine L cells, are important gut hormones that coordinate gastrointestinal physiology, metabolism, and appetite. We aimed to investigate the role of olfactory receptor (OR) OR51E1 in GLP-1 and PYY secretion. We analyzed the expression of olfactory marker protein (OMP), an indicator of OR-mediated events in nonolfactory systems, in human intestinal L cells. Furthermore, we analyzed OMP and OR51E1 expression in
BACKGROUND: There are many non-cereal monocots of agronomic, horticultural, and biofuel importance. Successful transformation of these species requires an understanding of factors controlling expression of their genes. Introns have been known to affect both the level and tissue-specific expression of genes in dicots and cereal monocots, but there have been no studies on an intron isolated from a non-cereal monocot. This study characterizes the levels of GUS expression and levels of uidA mRNA tha
Graves' disease (GD) is an autoimmune disorder that causes the overproduction of thyroid hormones and consequent cascade of systemic metabolism dysfunction. Moreover, Graves' ophthalmopathy (GO) is the main extrathyroidal manifestation of Graves' disease (GD). The goal of the study was to identify metabolic signatures in association with diagnostic biomarkers of GD without GO and GO, respectively. Ninety metabolites were profiled and analyzed based on a non-targeted primary metabolite profiling
Ascorbate is an essential antioxidant substance for humans. Due to the lack of ascorbate biosynthetic enzyme, a human must intake ascorbate from the food source. Tomato is one of the most widely consumed fruits, thus elevation of ascorbate content in tomato fruits will improve their nutritional value. Here we characterized Solanum lycopersicum ASCORBATE PEROXIDASE 4 ( SlAPX4 ) as a gene specifically induced during fruit ripening. In tomatoes, ascorbate accumulates in the yellow stage of fruits,
Trends of severe hypoglycemia were associated with changes in drug classes rather than number of antidiabetic drugs. Relentless efforts to reduce the prescription of drugs with a high risk of hypoglycemia should be implemented, particularly for older women with multiple comorbidities.
Abscisic acid (ABA) is a key signaling molecule that mediates plant response to stress. Increasing evidence indicates that ABA also regulates many aspects of plant development, such as seed germination, leaf development, and ripening. ABA metabolism, including ABA biosynthesis and degradation, is an essential aspect of ABA response in plants. In this study, we identified four cytochrome P450 genes ( CaCYP707A1 , 2 , 3 , and 4 ) that mediate ABA hydroxylation, which is required for ABA degradatio
Hyperglycemia is associated with increased mortality and morbidity in patients with type 2 diabetes mellitus (T2DM) who are undergoing dialysis. Although dipeptidyl peptidase-4 (DPP-4) inhibitors have been widely used in end-stage renal disease (ESRD) patients with T2DM, there are few studies on their efficacy in this population. We studied the effect of 3 different DPP-4 inhibitors on metabolic parameters in ESRD patients with T2DM.Two hundred ESRD patients with T2DM who were treated with DPP-4
Abstract The production of pharmacological vaccines in plants has been an important goal in the field of plant biotechnology. GA733-2, the protein that is also known as colorectal carcinoma (CRC)-associated antigen, is a strong candidate to produce a colorectal cancer vaccine. Tomato is the one of the major targets for production of an edible vaccine, as tomato is a fruit consumed in fresh form. It also contains high content of vitamins that aid activation of immune response. In order to develop
Radioactive iodine (RAI) therapy is an effective treatment option for Graves’ disease. However, predicting treatment failures after RAI therapy remains controversial. The objective of this study was to investigate the factors associated with the success rate of RAI therapy for treatment of Graves’ hyperthyroidism. Thyroid functional outcome, pre-RAI ultrasonographic features, and clinical parameters were evaluated retrospectively in 98 patients followed up for at least 12 months after RAI (mean
GA733-2, an epithelial cell adhesion molecule highly expressed at the human colorectal carcinoma cell surface, is a candidate protein for the development of a colorectal cancer preventive vaccine. In this study, a signal peptide and c-terminal transmembrane domain truncated GA733-2 was fused to a His-tag, and the recombinant protein (rGA733-2) was expressed in Escherichia coli Rosetta (DE3) pLysS. rGA733-2 was expressed in the form of inclusion bodies, and the protein was purified using either a
