background the process of neoplastic transformation in the stomach has been reported to be associated with decreased expression of normal mucins of the gastric mucosa and denovo expression of mucins that are normally expressed in other organs. this association may be used as a means to bring new insights into biologic behavior and genetic pathways in the development of gastric cancer. there are...

the mucus layer plays an important role as an intermediate for the protection of the gut against acidic chyme, digestive enzymes, and pathogens; in addition, it acts as a lubricant and facilitator of nutrient transportation. phytogenic compounds seem to promote intestinal mucus production. objectives: the current study was conducted to investigate the effects of low and high levels of energy an...

background: black seed (bs) is used in traditional medicine as a therapy for a variety of diseases including allergic asthma. materials and methods: in the present study, anti-inflammatory and immunomodulatory effects of bs on cytokine gene expression, lung airway eosinophilia and goblet cell hyperplasia were examined in a mouse mice model of allergic asthma. groups of 6-week-old female balb/c ...

Gram-negative bacteria can stimulate mucin production but excessive mucus supports bacterial infection and consequently leads to airway obstruction. Therefore the effect of dexamethasone (DEX) and the antioxidant acetyl-cysteine (ACC) on bacterial induced mucus expression was investigated. Explanted human airway mucosa and mucoepidermoid cells (Calu-3) were stimulated with lipopolysaccharide (L...

To investigate which retinoid receptors are critical in the regulation by all-trans-retinoic acid (RA) of the mucin genes MUC2, MUC5AC and MUC5B in cultured normal human tracheobronchial epithelial (NHTBE) cells, we used pan-RAR-, pan-RXR- and RAR- isotype (alpha, beta and gamma)-selective agonists and RARalpha- and RARgamma-selective antagonists (RAR is RA receptor and RXR is retinoid X recept...

Our recent studies have demonstrated that AQP5 is involved in the metastatic potential of lung cancer. Here, our aim was to explore the effects of AQP5 expression on mucin production in lung adenocarcinoma. We tested MUC5AC and MUC5B mucin production induced by AQP5 expression in lung adenocarcinoma metastasis. Lung adenocarcinoma cells with different levels of AQP5 expression were used in this...

Interleukin 1beta(IL-1beta), a proinflammatory cytokine, is related with inflammatory diseases and it up-regulates MUC2 gene expression and mucin secretion. This study was designed to investigate the signal transduction pathway of the IL-1beta-mediated MUC2 gene expression and mucin secretion in human airway epithelial cells. In cultured human airway NCI-H292 epithelial cells, the steady state ...

Complementary DNA clones encoding four different mucin core peptides have been isolated. However, the expression of these mucin genes in the colon has not been systematically studied. The present investigation used Northern blot analysis to study the expression of MUC1, MUC2, MUC3, and MUC4 mRNA in paired normal and cancerous colonic tissues, and nine colon cancer cell lines. Results were corre...
