background: interfering with cell proliferation and survival is a critical role for antineoplastic drugs leading to cell death through induction of apoptosis. alternative treatments with herbal extracts offer insights into acute myeloid leukemia (aml) therapy. parthenolide (ptl), an extract from feverfew, induces apoptosis in primary human leukemia stem cells (lscs) and bulk leukemic cell popul...
Evidence is presented which confirms that temperature-sensitive (ts) mutants with an RNA- phenotype are spontaneously selected in persistent infection of cell lines with Newcastle disease virus. Persistently infected BHK-21 cells, maintained since 1973, produce no interferon and are completely susceptible to vesicular stomatitis virus. Persistent infection of a canine kidney cell line (MDCK) te...
This study describes the development of Cryptosporidium parvum in MDCK, MA-104, Hep-2 and Vero cell lines. Differences in susceptibility, infectivity, and the methodology of excystation were determined. Various solutions were considered to determine the factors which enhanced the excystation (eg with and without sodium hypochlorite, trypsin or sodium taurocholate). It was shown that the sporozo...
Embryonic development requires cell migration in response to positional cues. Yet, how groups of cells recognize and translate positional information into morphogenetic movement remains poorly understood. In the developing kidney, the ureteric bud epithelium grows from the nephric duct towards a group of posterior intermediate mesodermal cells, the metanephric mesenchyme, and induces the format...
As a model for bacterium-induced epithelial cell injury, we have studied the interaction of Pseudomonas aeruginosa with polarized Madin-Darby canine kidney (MDCK) cells grown on filters. Following an initial period of bacterial adhesion, foci of injured host cells, which consisted of a central region of cell debris, surrounded by cells that were permeable and apparently necrotic, were formed. H...
The antimalarial drug chloroquine is eliminated to a significant extent by renal tubular secretion. The molecular mechanism of renal chloroquine secretion remains unknown. We hypothesized that organic cation transporter 2 (OCT2) and multidrug and toxin extrusion protein 1 (MATE1), localized in the basolateral and luminal membranes of proximal tubule cells, respectively, are involved in chloroqu...
Lamium album L. is a perennial herb widely used in folk medicine. It possesses a wide spectrum of therapeutic activities (anti-inflammatory, astringent, antiseptic, antibiotic, antispasmodic, antioxidant and anti-proliferative). Preservation of medicinal plant could be done by in vitro propagation to avoid depletion from their natural habitat. It is important to know whether extracts from L. al...
mycoplasma and ureaplasma species are the most serious contaminants of cell cultures and this remains one of the major problem encountered in biological research using cell cultures. the aim of this study was to investigate the rate of mycoplasma and a total of 100 different cell culture specimens including, r228, hela, vero, mdck, l20, rd and hep2 were collected. then the specimens were invest...
STUDY OBJECTIVE To evaluate P-glycoprotein (P-gp)-mediated renal drug interactions in an in vitro model of tubular secretion. DESIGN In vitro experiment. SETTING University-affiliated pharmacokinetics laboratory. CELL LINES: Madin-Darby canine kidney (MDCK), multidrug-resistant-1 (MDR1)-MDCK, and human colon carcinoma (Caco-2) cells. INTERVENTION Transepithelial transport (basolateral-to-...
objective: nucleostemin (ns) is a recently identified gene that is expressed mainly in the nucleoli of neuronal, embryonic and mesenchymal stem cells which plays a role in their self renewal. over expression of this gene has been reported in several cancer cell lines tumoral tissues including gastric, hepatic and prostate cancer. in this study, we investigated the effects of suppression of this...
