Catalase is one of the crucial antioxidant enzymes with diverse applications in textile, food industries, wastewater treatment, cosmetics, and pharmaceutics, which, however, highly sensitive to environmental challenges. Resisting loss activity prolongation formulation storage can be achieved via catalase entrapment into insoluble carriers. Affordable degradable vaterite proposed as amicable mat...

BACKGROUND In this study, we investigated whether lobetyolin, lobetyol, and methyl linoleate derived from Codonopsis pilosula affect MUC5AC mucin secretion, production, and gene expression from airway epithelial cells. METHODS Confluent NCI-H292 cells were pretreated with lobetyolin, lobetyol, or methyl linoleate for 30 minutes and then stimulated with phorbol 12-myristate 13-acetate (PMA) fo...

The hypothesis that dietary proteins or their hydrolysates may regulate intestinal mucin discharge was investigated in the isolated vascularly perfused rat jejunum using an enzyme-linked immunosorbent assay for rat intestinal mucins. On luminal administration, casein hydrolysate [0.05-5% (wt/vol)] stimulated mucin secretion in rat jejunum (maximal response at 417% of controls). Lactalbumin hydr...

Mucin secretion by airway goblet cells is under the control of apical P2Y2, phospholipase C-coupled purinergic receptors. In SPOC1 cells, the mobilization of intracellular Ca2+ by ionomycin or the activation of protein kinase C (PKC) by phorbol 12-myristate 13-acetate (PMA) stimulates mucin secretion in a fully additive fashion [L. H. Abdullah, J. D. Conway, J. A. Cohn, and C. W. Davis. Am. J. ...

The prognostic value of histologic classifications of gastric adenocarcinoma is controversial, although they have been commonly used. The clinical significance of the mucin phenotype has not been clarified. This study was conducted to determine the clinical significance of mucin phenotype as a possible prognostic factor. Mucin histochemistry by paradoxical concanavalin A (Con A) staining and im...

Excessive airway mucin production contributes to airway obstruction in lung diseases such as asthma and chronic obstructive pulmonary disease. Respiratory infections, such as atypical bacterium Mycoplasma pneumoniae (Mp), have been proposed to worsen asthma and chronic obstructive pulmonary disease in part through increasing mucin. However, the molecular mechanisms involved in infection-induced...
