High expression of glucose transporter family members, which augment glucose uptake and glycolytic flux, has been shown to play a pivotal role in the proliferation and survival of tumor cells, contributing to the energy supply, biosynthesis and homeostasis of cancer cells. Among the many members, solute carrier family 2 member 1 (SLC2A1) encodes a...

Physical activity has been found to aid the maintenance of health in the elderly. Exercise-induced skeletal muscle contractions lead to the production and secretion of many small proteins and proteoglycan peptides called myokines. Thus, studies on myokines are necessary for ensuring the maintenance of skeletal muscle health in the elderly. This rev...

We investigated the effect of endoplasmic reticulum (ER) protein 29 (ERp29) on thyroglobulin (Tg) secretion and its negative regulation by microRNAs (miRNAs). ERp29 overexpression promoted Tg secretion from thyrocytes of PCCL3 cells via activation of ER stress sensors, including activation of transcription factor 6 fragmentation, XBP1 mRNA splicing...

Ninety percent of patients with scrub typhus (SC) with vasculitis-like syndrome recover after mild symptoms; however, 10% can suffer serious complications, such as acute respiratory failure (ARF) and admission to the intensive care unit (ICU). Predictors for the progression of SC have not yet been established, and conventional scoring systems for I...

Ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX) is involved in the epigenetic regulation. A previous mouse xenograft study revealed that UTX knockdown is associated with downregulated expression of matrix metalloproteinase-11 (MMP-11). The authors investigated 224 cases of breast cancer from Kangbuk Samsung Medical Center betw...

Background Matrix metalloproteinase-9 (MMP-9) is associated with remodelling of the extracellular matrix and invasion in various cancers. Identifying proteins connected to high MMP-9 expression is important in explaining its mechanisms. Our study aims to shed light on genes associated with high MMP-9 expression and to discuss their clinical impact...

The revised criteria of the 8th American Joint Committee on Cancer (AJCC) cancer staging system consider depth of invasion as one of the factors that determine stage in distal bile duct (DBD) cancer, but exclude adjacent organ invasion. The aims were to evaluate the association between adjacent organ invasion and relapse-free survival (RFS) and ove...

There is few information about troponin gene expression by starvation in insect skeletal muscle and digestive tracts. The objective of this study was to perform molecular cloning of troponin I from the two-spotted cricket, Gryllus bimaculatus (GrybiTnI) and determine its expression patterns in three different skeletal muscles and digestive tracts d...

Background/Aims: To evaluate the usefulness of modified ultrasonographic scoring system (mUSSS) compared to that of liver stiffness measurement (LSM) by transient elastography in diagnosis of mild to moderate cirrhosis. Method: One hundred and five patients with only alcoholic liver disease (96 males, 9 females; age, 50.5 ± 10.0 year-old) were enro...

Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular sh...

Aims: Breast cancers are heterogeneous, making it essential to recognise several biomarkers for cancer outcome predictions. Ki67 proliferation index and B cell lymphoma 2 (BCL2) proteins are widely used as prognostic indicators in many types of malignancies. While Ki67 is a marker of normal or tumour cell proliferation, BCL2 plays a central role i...

GATA3 and fascin proteins are known prognostic markers in several cancers. GATA3 is a key regulator of mammary gland morphogenesis and luminal cell differentiation, whereas fascin is a pro-metastatic actin-bundling protein. In this study, we analyzed and compared the predictive abilities of GATA3 and fascin for clinical outcomes of patients with br...
