Bacterial decomposition of butterfish and smelts in small sealed jars containing seawater and other solutions, for periods ranging from 65 to 205 days, results in a large increase in concentrations of dissolved bicarbonate, carbonate, and ammonia (plus volatile amines). Accompanying this is a rise in pH and the precipitation of Ca(++) ion from solution. The Ca(++) is not precipitated as CaCO(3)...

Decay-accelerating factor (DAF) has been reported to be a cellular receptor for several enteroviruses. Buffalo green monkey kidney (BGMK) cells expressing human DAF (BGMK-hDAF cells) showed increased susceptibility and sensitivity to several types of enteroviruses compared to wild-type BGMK cells. When 17 frozen positive clinical samples were tested, BGMK cells detected 8 and BGMK-hDAF cells de...

In arid and semi-arid lands, people eats many kinds of spices. Capsaicin is one effect active component of spices. Previously we demonstrated that capsaicin induced tight junction (TJ) opening in human intestinal Caco-2 cells. We showed that the increase of TJ permeability was involved in actin polymerization. However the underlying mechanisms are unclear. The major aims of this study were to d...

Cetuximab is widely used in patients with metastatic colon cancer expressing wildtype KRAS. However, acquired drug resistance limits its clinical efficacy. Exosomes are nanosized vesicles secreted by various cell types. Tumor cell-derived exosomes participate in many biological processes, including tumor invasion, metastasis, and drug resistance. In this study, exosomes derived from cetuximab-r...

Fusobacterium nucleatum (F. nucleatum) plays a critical role in gastrointestinal inflammation. However, the exact mechanism by which F. nucleatum contributes to inflammation is unclear. In the present study, it was revealed that F. nucleatum could induce the production of proinflammatory cytokines (IL-8, IL-1β and TNF-α) and reactive oxygen species (ROS) in Caco-2 colorectal) adenocarcinoma cel...

The Caco-2 model is employed in pre-clinical investigations to predict the likely gastrointestinal permeability of drugs because it expresses cytochrome P450 enzymes, transporters, microvilli and enterocytes of identical characteristics to the human small intestine. The FDA recommends this model as integral component of the Biopharmaceutics Classification System (BCS). Most dedicated laboratori...

The present study aimed at exploring the potential of the P-glycoprotein (P-gp) transporters as a barrier to the repaglinide (REG) epithelial permeability. In-vitro intestinal absorption models, the everted gut sac, and Caco-2 cell line, were used to study the possible role of P-gp in intestinal transport of REG. In the everted gut sacs, apparent permeability coefficients showed cargo concentra...

Introduction: Efforts are made to identify the new potential components such as anticancer drugs. Medicinal plants belonging to Euphorbia genus are widely studied with promising effects. The current study aimed at investigating the effect of ethanolic extract of the root of E. tehranica, grown in Iran, on Caco-2 human colorectal cancer cell-line. Methods: The Caco-2 cells were treated with dif...

Abstract Two polyester-lignite composite coated urea slow-release fertilizers (SRFs; Poly3 and Poly5) were developed their physicochemical properties studied. Both these SRFs significantly (p < 0.05) extended the release compared to uncoated urea; Poly5 by 117 172 h, respectively. The characteristics of further enhanced linseed oil application (Poly5-linseed). SEM images demonstrated coating...

For the development of an efficient intestinal delivery system for Porcine interferon-α (PoIFN-α), the understanding of transport mechanisms of which in the intestinal cell is essential. In this study, we investigated the absorption mechanisms of PoIFN-α in intestine cells. Caco-2 cells and fluorescein isothiocyanate-labeled (FITC)-PoIFN-α were used to explore the whole transport process, inclu...
