Plumbagin, a quinonoid found in the plants of the Plumbaginaceae, possesses medicinal properties. In this study we investigated the anti-proliferative and apoptotic activity of plumbagin by using two human colonic cancer cell lines, HT29 and HCT15. IC50 of Plumbagin for HCT15 and HT29 cells (22.5 µM and 62.5 µM, respectively) were significantly different. To study the response of cancer cells d...

Caveolin-1 reportedly acts as a tumor suppressor and promotes events associated with tumor progression, including metastasis. The molecular mechanisms underlying such radical differences in function are not understood. Recently, we showed that caveolin-1 inhibits expression of the inhibitor of apoptosis protein survivin via a transcriptional mechanism involving the beta-catenin-Tcf/Lef pathway....

OBJECTIVES The colorectal cancer stem cells (CSCs) with the CD133(+) phenotype are a rare fraction of cancer cells with the ability of self-renewal, unlimited proliferation and resistance to treatment. Quercetin has anticancer effects with the advantage of exhibiting low side effects. Therefore, we evaluated the anticancer effects of quercetin and doxorubicin (Dox) in HT29 cancer cells and its ...

Entamoeba histolytica, which causes amoebic colitis and occasionally liver abscess in humans, is able to induce host cell death. However, signaling mechanisms of colon cell death induced by E. histolytica are not fully elucidated. In this study, we investigated the signaling role of NOX in cell death of HT29 colonic epithelial cells induced by E. histolytica. Incubation of HT29 cells with amoeb...

Abstract Background In the current study, folic acid-conjugated PEG-PCL-PEG triblock copolymer were synthesized and loaded with 5-fluorouracil magnetite nanoparticles (5-FU-SPION-PEG-PCL-PEG-FA) for targeted delivery of drug to HT29 human colon cancer cells CT26 mouse model. The characterized by nuclear magnetic resonance spectroscopy (NMR) transmission electron microscopy (TEM). cellular uptak...

A clone HT29-18 has been isolated from the parent cell line HT-29, which derived from a human colon adenocarcinoma (Fogh, J., and G. Trempe, 1975, Human Tumor Cells in Vitro, J. Fogh, editor, Plenum Publishing Corp., New York, 115-141). This clone is able to differentiate as the parent cell line does. Differentiation occurs when glucose is replaced by galactose in the culture medium (Pinto, M.,...

BACKGROUND Liver metastasis is the most common cause of death in patients with colorectal cancer. Despite extensive research into the biology of cancer progression, the molecular mechanisms that drive colorectal cancer metastasis are not well characterized. METHODS HT29 LM1, HT29 LM2, HT29 LM3 cell lines were derived from the human colorectal cancer cell line HT29 following multiple rounds of...

CD10 expression is associated with metastases of colorectal cancer (CRC). In the present study, we examined association of CD10 with liver metastasis of CRC cells to clarify the therapeutic significance of CD10. CD10-positive human colon cancer cell line, HT29 cells showed inhibition of growth, invasion and colony formation by treatment with CD10 antisense S-oligodeoxynucleotide (S-ODN). In the...
