chitinase/necrosis

Expression of the chitinase 3-like protein HC-gp39 (human cartilage glycoprotein 39) is associated with conditions of increased matrix turnover and tissue remodelling. High levels of this protein have been found in sera and synovial fluids of patients with inflammatory and degenerative arthritis. In

Pseudomonas aeruginosa causes hospital-acquired pneumonia and is associated with high mortality. An effective response to such an infection includes efficient clearance of pathogenic organisms while limiting collateral damage from the host inflammatory response, known as host resistance and host

BACKGROUND Clara cell 10-kD (CC10) protein, an antiinflammatory molecule, is involved in inflammatory upper airway diseases, but its regulatory role is unclear, particularly in the process of chronic rhinosinusitis (CRS). OBJECTIVE To investigate the regulatory mechanisms of CC10 in eosinophilic CRS

OBJECTIVE To determine the intracellular proteome of normal human chondrocytes stimulated with interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha) and to ascertain differences in the protein expression patterns of these 2 cytokines. METHODS Normal human knee cartilage

Coagulation is a critical component in the progression of liver disease. Identification of key molecules involved in the intrahepatic activation of coagulation (IAOC) will be instrumental in the development of effective therapies against liver disease. Using a mouse model of concanavalin A

Theobroma cacao L. plants over-expressing a cacao class I chitinase gene (TcChi1) under the control of a modified CaMV-35S promoter were obtained by Agrobacterium-mediated transformation of somatic embryo cotyledons. Southern blot analysis confirmed insertion of the transgene in eight independent

CHI3L1 (chitinase-3-like protein 1) is a glycoprotein consisting of 383 amino acids with a molecular mass of 40 kDa, and its serum level is elevated in inflammatory diseases. Although CHI3L1 is described as a biomarker of inflammation, the function of this protein is not completely understood. In

OBJECTIVE To compare the response of chondrocytes and cartilage matrix to injurious mechanical compression and treatment with interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha), by characterizing proteins lost to the medium from cartilage explant culture. METHODS Cartilage

A complementary DNA encoding an ethylene-inducible acidic chitinase of azuki bean (Vigna angularis) was isolated, and its complete nucleotide sequence was determined. The nucleotide and deduced amino-acid sequence were very similar to those of an acidic chitinase from cucumber leaves that had been

BACKGROUND Indian jujube is a fruit abundantly cultivated in Taiwan. Its major allergen in latex-fruit syndrome is Ziz m 1 of the chitinase III family. The Ziz m 1 Pichia (rZiz m 1-P) has chitinase activity but not Ziz m 1 E. coli (rZiz m 1-E). OBJECTIVE This study examined whether plant chitinase

Chitinase 1 (CHIT1) is secreted by activated macrophages. Chitinase activity is raised in atherosclerotic patient sera and is present in atherosclerotic plaque. However, the role of CHIT1 in atherosclerosis is unknown. Preliminary studies of atherosclerosis in cynomolgous monkeys revealed CHIT1 to

C57BL/6 mice develop an allergic bronchopulmonary mycosis following intratracheal inoculation of Cryptococcus neoformans 24067. We determined that only low levels of tumor necrosis factor alpha (TNF-alpha) are produced in the lungs following infection. Thus, the objective of the present studies was

Human chitotriosidase (Chit), a chitinolytic enzyme, is a member of the chitinase family. In human plasma, Chit activity has been proposed as a biochemical marker of macrophage activation in several lysosomal diseases. Recently we found that Chit activity is higher in patients affected by Plasmodium

Chitinase 3-like 1 (CHI3L1) is a secreted glycoprotein that mediates inflammation, macrophage polarization, apoptosis, and carcinogenesis. The expression of CHI3L1 is strongly increased by various inflammatory and immunological conditions, including rheumatoid arthritis, multiple sclerosis,
