The present study aimed to investigate the effects of JWA knockout (JWA-/-) on malignant transformation of murine embryonic fibroblast (MEF) cells using a conditional JWA-/- mouse model. Once MEF cells were prepared, the potential role of JWA-/- on proliferation, migration, invasion and colony formation of MEF cells was investigated by cytological examination. The effects of JWA-/- on the regul...

INTRODUCTION One of the major contributing factors, which may cause failure of endodontic treatment, is the presence of residual microorganisms in the root canal system. For years, most dentists have been using calcium hydroxide (CH) as the intracanal medicament between treatment sessions to eliminate remnant microorganisms. Reducing the size of CH particles into nanoparticles enhances the pene...

The humanized liver mouse model is being exploited increasingly for human drug metabolism studies. However, its model stability, intercommunication between human hepatocytes and mouse nonparenchymal cells in liver and murine intestine, and changes in extrahepatic transporter and enzyme expressions have not been investigated. We examined these issues in FRGN [fumarylacetoacetate hydrolase (Fah-/...

The injury border zone (IBZ), a region of transitional tissue between intact myocardium and the ischemic area, is often the site of lethal reentrant arrhythmia generation in post-myocardial infarction (MI) patients. Disruption to normal connexin43 (Cx43) localization at the intercalated disc (ID), separation of myocytes by activated fibroblasts and deposited scar tissue are thought to be factor...

the skin is the largest tissue of man with several functions. cosmetics/cosmeceuticals agents always are needed to be evaluated for their detrimental effects on the skin. nowadays, the therapeutic potential of stem cells has and fibroblasts have increased the hope for a successful cell therapy in aesthetic medicine. stem cells are unspecialized cells capable of renewing themselves through cell ...

Mouse fibroblasts (L cells) were incubated for 5 h with 1,000 U of murine fibroblast interferon (MuIFN alpha+ beta) per ml and then were infected with either Chlamydia trachomatis (LGV 440), C. psittaci (6BC), or C. psittaci (Cal 10). Intracellular development of C. trachomatis was reduced 90% in interferon-treated cells 24 h after infection when compared with controls, whereas C. psittaci grow...

In the course of structure-activity relationship studies, diversely substituted 1-(beta-D-glucopyranosyl)-isoindigo derivatives were prepared from commercially available indolines. Their antiproliferative activities were evaluated toward a panel of human solid cancer cell lines (PC 3, DLD-1, MCF-7, M4Beu, A549, PA 1), a murine cell line (L929) and a human fibroblast primary culture to get an in...

increased arginase activity in the airways decreases l-arginine and causes deficiency of bronchodilating and anti-inflammatory nitric oxide (no) in asthma. as, it is suggested that l-arginine may have therapeutic potential in asthma treatment, we aimed to investigate the effects of inhaled l-arginine on oxygen saturation (sao₂) and airway histology in a murine model of acute asthma. twenty eigh...
