Pulmonary fibrosis is a fatal progressive disease with no effective therapy. Transforming growth factor (TGF)-β1 has long been regarded as a central mediator of tissue fibrosis that involves multiple organs including skin, liver, kidney, and lung. Thus, TGF-β1 and its signaling pathways have been attractive therapeutic targets for the development of antifibrotic drugs. However, the essential bi...

Atherosclerosis is initiated by the infiltration of monocytes into the subendothelial space of the vessel wall and subsequent lipid accumulation of the activated macrophages. The molecular mechanisms involved in the anomalous behavior of macrophages in atherogenesis have only partially been disclosed. Chitotriosidase and human cartilage gp-39 (HC gp-39) are members of the chitinase family of pr...

BACKGROUND Nephropathic cystinosis is an inherited autosomal recessive lysosomal storage disorder characterized by the pathological accumulation and crystallization of cystine inside different cell types. WBC cystine determination forms the basis for the diagnosis and therapeutic monitoring with the cystine depleting drug (cysteamine). The chitotriosidase enzyme is a human chitinase, produced b...

PURPOSE Gaucher disease is caused by a β-glucocerebrosidase (GBA) deficiency. The aim of this study is to investigate the clinical and genetic characteristics according to subtypes of Gaucher disease in the Korean population. METHODS Clinical findings at diagnosis, GBA mutations, and clinical courses were reviewed in 20 patients diagnosed with Gaucher disease. RESULTS Eleven patients were d...

UNLABELLED Gaucher's disease is a lysosomal storage disorder due to a genetically transmitted deficiency of the enzyme glucocerebrosidase. In the most common form of the disease (type 1), accumulation of glucosylceramide in the reticuloendothelial cells of liver, spleen, and bone marrow leads to visceromegaly, anemia, thrombocytopenia, and osteopenia. Skeletal manifestations secondary to infilt...

Magnesium is crucial for baculovirus transmission in Culex nigripalpus (Theobald) and Culex quinquefasciatus (Say) larvae. However, the mechanistic role of magnesium in baculovirus transmission is unknown. To investigate the possible role of host response factors in baculovirus transmission, suppression subtractive hybridization was used to identify genes differentially transcribed after magnes...

Human Glyco_18 domain-containing proteins constitute a family of chitinases and chitinase-like proteins. Chitotriosidase and AMCase are true enzymes which hydrolyse chitin and have a C-terminal chitin-binding domain. YKL-40, YKL-39, SI-CLP and murine YM1/2 proteins possess solely Glyco_18 domain and do not have the hydrolytic activity. The major sources of Glyco_18 containing proteins are macro...

Actinopterygii express two types of chitinase (acidic fish chitinase-1 (AFCase-1) and acidic fish chitinase-2 (AFCase-2)) that are active at acidic pHs and involved in digestion in the stomach. We proposed the existence of a new fish chitinase that has a non-digestive function. In this study, we used Sebastiscus marmoratus, for which characteristics and cDNA cloning of chitinase isozymes (SmChi...

Intercalation of polyatomic molecules into a superconductor can drastically affect the properties of the compound. A mechanism responsible for a large increase in Tc for such systems is proposed. It explains the recent remarkable observation of high Tc superconductivity in the hole-doped C60/CHX3 (X≡Cl,Br) compounds and the large shift in their Tc upon Cl→Br substitution. The increase in Tc is ...
