EFhd2/Swiprosin-1 is a cytoskeletal Ca-binding protein implicated in Ca-dependent cell spreading and migration in epithelial cells. EFhd2 domain architecture includes an N-terminal disordered region, a PxxP motif, two EF-hands, a ligand mimic helix and a C-terminal coiled-coil domain. We reported previously that EFhd2 displays F-actin bundling activity in the presence of Ca and this activity depends on the coiled-coil domain and direct interaction of the EFhd2 core region.

Protective Effect of Tempol against Cisplatin-Induced Ototoxicity.

Int J Mol Sci

November 2016

Department of Otolaryngology-Head and Neck Surgery, Chosun University School of Medicine, Gwangju 61453, Korea.

One of the major adverse effects of cisplatin chemotherapy is hearing loss. Cisplatin-induced ototoxicity hampers treatment because it often necessitates dose reduction, which decreases cisplatin efficacy. This study was performed to investigate the effect of Tempol on cisplatin-induced ototoxicity in an auditory cell line, House Ear Institute-Organ of Corti 1 (HEI-OC1).

p53R2 regulates thioredoxin reductase activity through interaction with TrxR2.

Biochem Biophys Res Commun

January 2017

Laboratory of Genomic Instability and Cancer Therapeutics, Cancer Mutation Research Center, Chosun University School of Medicine, 375 Seosuk-dong, Gwangju 61452, Republic of Korea; Department of Cellular and Molecular Medicine, Chosun University School of Medicine, 375 Seosuk-dong, Gwangju 61452, Republic of Korea. Electronic address:

Ribonucleotide reductase small subunit p53R2 is a member of the ribonucleotide reductase family that supplies dNTPs for nuclear and mitochondrial DNA replication and repair. Here, we have identified a mitochondrial thioredoxin reductase 2 (TrxR2) as a novel p53R2-binding protein. We demonstrated a direct interaction between the two, and observed that p53R2 stimulated the enzymatic activity of TrxR in vitro.

Systematic review and meta-analysis of prostatic artery embolisation for lower urinary tract symptoms related to benign prostatic hyperplasia.

Clin Radiol

January 2017

Department of Urology, Chosun University Hospital, Chosun University School of Medicine, Gwangju, Republic of Korea. Electronic address:

Aim: To evaluate the efficacy of prostatic artery embolisation (PAE) in lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) at short- and mid-term follow-up.

Materials And Methods: The current study included 484 BPH patients from seven eligible studies. A meta-analysis was performed to determine the mean differences in parameters associated with LUTS, including the international prostate symptom score (IPSS), peak urinary flow (Qmax), post-void residual volume (PVR), quality of life score (QoL), prostate-specific antigen level (PSA), and prostatic volume (PV), between baseline and follow-up periods.

Purpose: Laparoscopic subtotal cholecystectomy (LSC) can be an alternative surgical technique for difficult cholecystectomies. Surgeons performing LSC sometimes leave the posterior wall of the gallbladder (GB) to shorten the operation time and avoid liver injury. However, leaving the inflamed posterior GB wall is a major concern.

The omega loop in β-lactamases plays a pivotal role in substrate recognition and catalysis, and some mutations in this loop affect the adaptability of the enzymes to new antibiotics. Various mutations, including substitutions, deletions, and intragenic duplications resulting in tandem repeats (TRs), have been associated with β-lactamase substrate spectrum extension. TRs are unique among the mutations as they cause severe structural perturbations in the enzymes.

Platelets are essential for progression of atherosclerotic lesions, plaque destabilization, and thrombosis. They secrete and express many substances that are crucial mediators of coagulation, inflammation, and atherosclerosis. Mean platelet volume (MPV) is a precise measure of platelet size, and is routinely reported during complete blood count analysis.

Background: High C-reactive protein (CRP) and mean platelet volume (MPV) levels are associated with poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to evaluate the relationship between CRP level or MPV and infarct transmurality in patients with STEMI.

Methods: We retrospectively reviewed CRP level, MPV, and infarct transmurality in 112 STEMI patients who were assessed with contrast-enhanced cardiac magnetic resonance imaging.

Effect of hydroxyethyl starch on blood glucose levels.

Korean J Anesthesiol

August 2016

Department of Anesthesiology and Pain Medicine, Chosun University School of Medicine, Gwangju, Korea.

Background: Hydroxyethyl starch (HES), a commonly used resuscitation fluid, has the property to induce hyperglycemia as it contains large ethyl starch, which can be metabolized to produce glucose.

Colorectal polyps are classified as neoplastic or non-neoplastic on the basis of malignant potential. All neoplastic polyps should be completely removed because both the incidence of colorectal cancer and the mortality of colorectal cancer patients have been found to be strongly correlated with incomplete polypectomy. The majority of colorectal polyps discovered on diagnostic colonoscopy are diminutive and small polyps; therefore, complete resection of these polyps is very important.

miR146a-mediated targeting of FANCM during inflammation compromises genome integrity.

Oncotarget

July 2016

Laboratory of Genomic Instability and Cancer Therapeutics, Cancer Mutation Research Center, Chosun University School of Medicine, Gwangju, Republic of Korea.

Inflammation is a potent inducer of tumorigenesis. Increased DNA damage or loss of genome integrity is thought to be one of the mechanisms linking inflammation and cancer development. It has been suggested that NF-κB-induced microRNA-146 (miR146a) may be a mediator of the inflammatory response.

Background: Parafibromin is a product of the tumor suppressor gene that has been studied as a potential indicator of tumor aggressiveness in the parathyroid, breast, colorectum, and stomach. However, the clinical significance and potential function of parafibromin expression in head and neck squamous cell carcinomas remain largely unknown. The aim of this study was to evaluate the expression of parafibromin in laryngeal squamous cell carcinoma (LSCC) and to verify its potential as a biomarker of tumor behavior.
