Dietary protein might modulate mucin flow and intestinal mucin gene expression. Since unheated phaseolin from Phaseolus vulgaris bean is resistant to digestion and increases gut endogenous protein losses, we hypothesised that unheated phaseolin influences mucin flow and gene expression, and that phaseolin heat treatment reverses these effects. The hypothesis was tested using a control diet cont...

The present study was aimed at investigating the role of in ovo administered amino acids: lysine, arginine, threonine or methionine plus cysteine (Met+Cys) in 14-day embryos on expression profile of growth (chicken growth hormone (cGH), insulin like growth factors (IGF) I and II, and mucin) and immunity related genes (IL-2, IL-4, IL-6, IL-12, TNF-α, and IFN-γ). On incubation day (ID) 18, higher...

Mucins locate to the apical surfaces of all wet-surfaced epithelia including ocular surface. The functions of the mucins include anti-adhesive, lubrication, water retention, allergens and pathogen barrier function. Ocular surface pathologies, i.e. dry eye syndrome or allergic conjunctivitis, are reportedly associated with alteration of expression pattern of mucin components. Recent investigatio...

Twenty mucin genes have been identified and classified in two groups (encoding secreted membrane-bound proteins). Secreted mucins participate mucus formation by assembling a 3-dimensional network via oligomerization, whereas are anchored to the outer membrane mediating extracellular interactions cell signaling. Both associated with carcinogenesis progression epithelial cancers, therefore consid...

conclusions it can be concluded that the nettle extract can reduce blood glucose levels in diabetic mice, at least partly, by influencing the glut2 gene expression in mice liver. results the results showed that the nettle extract significantly decreased high levels of blood glucose (p < 0.001). the nettle extract also had a preventive effect on decrease in body weight. in addition, the results ...

Previous studies have suggested that mucin gene expression is tissue-specific; however, the relationship between unique mucin gene products and the biochemical properties of mucins is unknown. The purpose of this study was to determine the biochemical and molecular characteristics of mucin synthesized by adenocarcinoma cell lines derived from breast (ZR-75-1), stomach (MGC-803), pancreas (Capan...

Treatment of HT-29 cells with phorbol 12-myristate 13-acetate (PMA), an activator of protein kinase C (PKC), induces MUC2 expression. To investigate the role of PKC in regulating mucin genes in intestinal cells, we examined the regulation of MUC1, MUC2, MUC5AC, MUC5B, and MUC6 expression in two human mucin-producing colonic cell lines, T84 and HT29/A1. T84 and HT29/A1 cells (at 80-90% confluenc...

The nucleoside analogue gemcitabine displays therapeutic effects mainly against breast, ovarian and pancreatic cancer. Mucin, encoded by the gene MUC1, is a well-established tumor antigen expressed on these tumors. Knowledge of possible effects of chemotherapeutic drugs on the level of mucin epitope expression is important for the design of clinical protocols combining chemo- and immunotherapeu...
