Youngmi Kim, Minjeong Yeon, Dooil Jeoung
This study investigated the role of cancer/testis antigen DDX53 in regulating cancer stem cell-like properties. DDX53 shows co-expression with CD133, a marker for cancer stem cells. DDX53 directly regulates the SOX-2 expression in anticancer drug-resistant Malme3MR cells. DDX53 and miR-200bwere found to be involved in the regulation of tumor spheroid forming potential of Malme3M and Malme3MR cells. Furthermore, the self-renewal activity and the tumorigenic potential of Malme3M(R)-CD133 (+) cells were also regulated by DDX53...

Extrahepatic cholangiocarcinoma (ECC), a malignant tumor of biliary origin, has a poor prognosis with limited treatment options. The KRAS oncogene is the most commonly mutated gene in ECC and one of the factors that predicts a poor prognosis and low survival rate. L1 cell adhesion molecule (L1CAM) is expressed in ECC cells and acts as an independent poor prognostic factor in predicting patient survival. In this study we investigate the functional significance of L1CAM in ECC cells with activating KRAS mutation...

Long interspersed nuclear element-1 (LINE-1) is a retrotransposon that contains a CpG island in its 5-untranslated region. The CpG island of LINE-1 is often heavily methylated in normal somatic cells, which is associated with poor prognosis in various cancers. DNA methylation can differ between formalin-fixed paraffin-embedded (FFPE) and frozen tissues. Therefore, this study aimed to compare the LINE-1 methylation status between the two tissue-storage conditions in gastric cancer (GC) clinical samples and to evaluate whether LINE-1 can be used as an independent prognostic marker for each tissue-storage type...

Serratia marcescens is reported to possess the potential for industrial 2,3-butanediol or acetoin production by fermentation. But 2,3-butanediol or acetoin are always co-produced and this may make purification process difficult. So biocatalytic technologies may be the appropriate production methods. In this study, we developed an auto-inducing expression system based on pET system and swr quorum sensing system by using S. marcescens. By using this system, S. marcescens could be engineered as whole-cell biocatalyst to obtain 2,3-butanediol or acetoin...

Renal cell carcinoma (RCC) is the most common subtype of kidney cancer. Currently, there is a lack of efficient treatment for RCC. Bicyclol, an anti-hepatitis drug, has been demonstrated to possess anti-tumor properties. However, the effect of bicyclol in RCC remains elusive. Therefore, the aim of this study is to investigate the biological effects of bicyclol on RCC and the underlying mechanisms. The data from this study indicated that bicyclol markedly induced cell apoptosis and cell cycle arrest and increased the production of reactive oxygen species (ROS) in RCC cells...

The World Health Organization (WHO) classification of central nervous system (CNS) tumors was revised in 2016 with a basis on the integrated diagnosis of molecular genetics. We herein provide the guidelines for using molecular genetic tests in routine pathological practice for an accurate diagnosis and appropriate management. While astrocytomas and IDH-mutant (secondary) glioblastomas are characterized by the mutational status of IDH, TP53 , and ATRX , oligodendrogliomas have a 1p/19q codeletion and mutations in IDH, CIC , FUBP1 , and the promoter region of telomerase reverse transcriptase ( TERTp )...

AIM: The contribution of the inflammatory mediator interleukin-17 (IL-17) in nonsmall cell lung cancer (NSCLC) malignancy has been reported in the literature. MicroRNA-181a-5p (miR-181a-5p) acts as a tumor suppressor which can regulate target gene at the posttranscriptional level. Our study aimed to investigate the interaction between IL-17 and miR-181a-5p in NSCLC. METHODS: 35 patients with NSCLC and 24 COPD controls were selected and examined in our study. In vitro, H226 and H460 cell lines were exposed to different doses (20, 40, 60, and 80 ng/mL) of IL-17 to examine the effect of IL-17 on miR-181a-5p and vascular cell adhesion molecule 1 (VCAM-1) expression...
