Professor SiHyun Cho's research lab focuses on identifying and validating novel biomarkers for endometriosis, with a particular emphasis on urinary and serum proteins such as VDBP, sFlt-1, osteopontin, and COX-2. The lab investigates the molecular and immunological mechanisms underlying endometriosis pathogenesis, especially the roles of angiogenesis, inflammation, and immune modulation in different disease stages. Their work also explores therapeutic strategies, including the use of hormonal intrauterine devices for postoperative recurrence prevention. The lab integrates clinical observations with molecular biology to advance non-invasive diagnostics and targeted therapies for endometriosis.

Urinary VDBP levels are elevated in patients with endometriosis. They have limited value as a potential diagnostic biomarker for endometriosis but suggest it would be worthwhile to investigate other urinary proteins for this purpose.
The pathogenesis of minimal-to-mild endometriosis and moderate-to-severe endometriosis seems to be different. Increased sFlt-1 levels in serum and urine of minimal-to-mild disease indicate that sFlt-1 may have an important role in inhibiting angiogenic process of the disease.
Cox-2 expression increased in the eutopic endometrium and ovarian endometriotic tissue of the patients with endometriosis. These findings indicate that Cox-2 may be involved in the pathogenesis and progression of endometriosis.
Osteopontin may be involved in the pathogenesis of endometriosis and plasma OPN may be a useful non-invasive marker for the diagnosis of endometriosis.
The region of the murine major histocompatibility complex (MHC) between the Pb (A beta 3) and Ob (A beta 2) genes controls the expression of an intracellular complex named the LMP (low molecular weight polypeptide) complex. DNA probes for at least seven different genes mapping to this region were isolated. These hybridize to a minimum of eight different transcripts ranging from approximately 1.3 to 3.7 kilobases (kb). The deduced amino acid sequences of the corresponding cDNAs indicate that thre
Postoperative LNG-IUS use seemed to be comparable to the use of cyclic OC in preventing endometrioma recurrence.
Because energy production involves oxidative phosphorylation, mitochondria are major sources of reactive oxygen species in the cell. Recent findings indicate that mitochondrial DNA (mtDNA) variants may play a role in the etiology of certain autoimmune and chronic inflammatory diseases. The aim of this study was to investigate the possible association between mtDNA polymorphisms and susceptibility to endometriosis. This study included 198 patients with histologically confirmed endometriosis and 1
<b>Background:</b> Repair of DNA double strand break (DSB) is an important mechanism for maintaining genetic stability during a DNA damage event. Although, a growing body of recent evidence suggests that DNA DSBs and related repair mechanisms may be important in ovarian aging and in various cancers, there are few reports in endometriosis. We, therefore, examined expression levels of genes pertaining to DNA DSB repair in patients with endometriosis to assess the potential effects on ovarian reser
Individuals with atrial fibrillation (AF), especially women, have an increased risk of stroke and death. Although hormone replacement therapy (HRT) is widely used in postmenopausal women, the association between HRT use and AF risk is unclear. We aimed to investigate the association between various types of HRT and AF. This was a population-based retrospective cohort study from The Korean National Health Insurance Service-National Sample Cohort (2004-2015). Participants were aged 45-60 years and
Serum IL-32 levels are elevated in patients with endometriosis, and with combination of serum CA-125 levels, it may serve as a potential biomarker for endometriosis.
