background: p19 cells are mouse embryonic carcinoma cells which contain pluripotent ability, like stem cells, to differentiate into different cell lines. there are several properties for this cell line that make it a valuable cell model for study of developmental stages. methods: at the first step, pts2-egfp coding sequence which was cloned in pucd2.hygro vector was used for transfection in to ...

Cells of transplantable MC38 colon carcinoma of C57BL/6 mice were adapted to growth in vitro as the MC38/0 cell line. Along the establishing process, MC38/0 cells preserved their tumorigenicity. After transduction with a retroviral vector carrying murine interleukin 12 (mIL-12) genes and further selection, stable MC38/IL-12 transductant cells were obtained. These cells produced IL-12 (approx. 2...

Squamous cell carcinoma (SCC) of the anal canal is a rare condition comprising only 2-4% of all cancers of the colon, rectum and anus. The most common sites of metastases are liver and lung. We report a case of 34-year-old male, who presented with diarrhoeal illness and an acutely tender protruding anal lesion initially thought to be thrombosed external hemorrhoid. Examination under anaesthesia...

cancer is a major global problem and is the second leading cause of mortality in the developed countries.resistance to current chemotherapeutics and high incidence of adverse effects are the two principal reasons for developing new anticancer agents. phenylacetamide derivatives can act as potential anticancer agents. synthesis and screening of 2-(4-fluorophenyl)-n-phenylacetamide derivatives in...

The aim of our study was to investigate the effects of rabeprazole, a proton pump inhibitor, on MDR1 expressed on human colon carcinoma cell line, Caco-2, and MDR1-overexpressing human cervical carcinoma cell line, HeLa cells selected by exposure to 100 nM vinblastine (Hvr100-6 cells). Inhibitory effects of rabeprazole on MDR1-mediated transport of Rhodamine123 were examined in these cells. A t...

Abstract Objectives In our study, we aimed to (1) create a peritoneal metastasis (PM) model in nude mice, administer intraperitoneal chemotherapy using the infusion pump developed this model, and (2) compare efficacy of various drugs at different temperatures. Methods The was established mice CC531 colon carcinoma cell line. Models with were randomized into four groups seven animals each: Group...

Introduction Colorectal cancer cells can induce apoptosis in cells of various tissues [1]. Apoptosis can be induced by a number of factors such as Fas inducing apoptosis through the Fas/ FasL pathway; other factors involve the TRAIL pathway and TNF. It is known that metastasizing colon cancer cells express more FasL then primary carcinoma cells [2]. We investigated whether a rat colon carcinoma...

We have investigated the influence of Ki-ras oncogene on Met/hepatocyte growth factor (HGF) receptor signaling in human carcinoma cells. The model system used in these studies included the DLD-1 colon cancer cell line with a mutated Ki-ras allele, and the DKO-4 cell line generated from DLD-1, with its mutant Ki-ras allele inactivated by targeted disruption. These cell lines were transduced with...

A series of ruthenium and iridium complexes have been synthesized and characterized with 20 novel crystal structures discussed. The library of β-ketoiminato complexes has been shown to be active against MCF-7 (human breast carcinoma), HT-29 (human colon carcinoma), A2780 (human ovarian carcinoma), and A2780cis (cisplatin-resistant human ovarian carcinoma) cell lines, with selected complexes' be...
