Although AKT ⁄ protein kinase B is constitutively active in nonsmall cell lung cancer (NSCLC) cells and is an attractive target for enhancing the cytotoxicity of therapeutic agents, the distinct roles of the AKT isoforms in NSCLC are largely unknown. In the present study, we investigated the roles of AKT1 and AKT2 in NSCLC cells using RNAi. The siRNA targeting of AKT1 or AKT2 effectively decreased protein levels of AKT1 and AKT2, respectively, in A549 and H460 cells. Cisplatin treatment of these

The International Society for the Study of Vascular Anomalies classifies vascular anomalies into vascular tumors and vascular malformations. Vascular tumors are neoplasms of endothelial cells, among which infantile hemangiomas (IHs) are the most common, occurring in 5%-10% of infants. Glucose transporter-1 protein expression in IHs differs from that of other vascular tumors or vascular malformations. IHs are not present at birth but are usually diagnosed at 1 week to 1 month of age, rapidly prol

BACKGROUND: Community-acquired pneumonia (CAP) is a common respiratory disorder in children, which necessitates hospitalization. Bacterial pneumonia, especially lobar pneumonia and parapneumonic effusions, is associated with considerably severe clinical course and extensive alveolar infiltrates. Serum procalcitonin (PCT) level has been used to distinguish bacterial from viral infections, but its usefulness is disputed. The diagnostic accuracy and usefulness of PCT, C-reactive protein (CRP), eryt

Hereditary hemolytic anemia (HHA) is a very rare disease entity characterized by premature red blood cell (RBC) destruction and anemia due to intrinsic RBC defects. The 3 main etiologies causing HHA, in order of frequency, are RBC membrane disorders, hemoglobin disorders, and RBC enzyme disorders. The prevalence of HHA in Korea is very low, because hereditary spherocytosis (HS) is less common in Asians than in Caucasians-with an incidence of 1 in 5000 births-and because Korea is not located in t

There have been growing concerns about venous thromboembolism (VTE), especially in Western counties where the incidence is greater than Asian counties. In Korea, the annual incidence of VTE per 100,000 population in all age group, age group of 0–9 years and 10–19 years were 8.83, 0.19 and 0.71 in 2004, and increased to 13.8, 0.30 and 0.64 in 2008, respectively, showing significantly lower incidence of VTE in children and adolescents in comparison to adults [1]. Although the incidence of VTE is r

OBJECTIVES: To evaluate the prognostic value of ultrasound and MRI findings in patients with infantile hemangioma undergoing propranolol therapy. METHODS: This study was based on retrospective interpretation of prospectively acquired data. Thirty-eight consecutive patients (28 females and 10 males; mean age ± standard deviation, 3.2 ± 2.2 months) who underwent propranolol treatment for infantile hemangioma were included. Pre-treatment ultrasound images were assessed in terms of echogenicity, les

The first human bone marrow transplantation in a patient with hematologic malignancy took place in the 1950s, but only transient engraftment of the bone marrow was noted [1]. In the 1960s, additional information regarding the HLA system became available; the serologic HLA typing method was developed; and bone marrow transplantations for children with immnunodeficiency were successfully performed [2]. Hematopoietic stem cell transplantation (HSCT) has now become an established and potentially cur

Abstract Cell dose is one of the most important factors predicting successful outcome after cord blood transplantation (CBT), and the University of Minnesota group recently reported results of transplantation using 2 partially HLA-matched cord blood units for adult patients. Although a significant proportion of pediatric recipients would benefit by cell dose augmentation, data concerning multiple unit CBT in children are lacking by far. We investigated the feasibility of double unit CBT for pedi

Disparity of minor histocompatibility antigens (mHAs) is known to induce graft-versus-tumor and graft-versus-host disease reactions in stem cell transplantation. Not much information is available on genotypic and phenotypic distributions of the currently identified mHAs, especially in Korean population. Therefore, we report genotype and phenotype frequency analyses of 10 autosomal mHAs in 329 unrelated healthy Koreans using the Sequenom MassARRAY matrix-assisted laser desorption/ionization time-

Abstract Abstract 5157 Background: With the development of diagnostic technique, an accurate diagnosis of hereditary hemolytic anemia (HHA)- red blood cell (RBC) membranopathy, hemoglobinopathy, RBC enzymopahty – have been made. Therefore, we surveyed the prevalence and characteristics of patients diagnosed as HHA during recent five years in Korea. Methods: Through the use of questionnaires, information on the clinical and laboratory findings of HHA diagnosed from 2007 to 2011 in Korea was colle

Abstract TNF-related apoptosis-inducing ligand (TRAIL) is a potent inducer of apoptosis in most, but not all, cancer cells. The molecular factors regulating the sensitivity to TRAIL are still incompletely understood. The transcription factor nuclear factor-kappa B (NF-kB) has been implicated, but its exact role is controversial. In this study, we have investigated the role of NF-kB on enhancement of TRAIL cytotoxicity in neuroblastoma cells. IkB kinase (IKK) inhibitor decreased basal NF-kB activ
