Metal-based drugs with extensive clinical applications hold great promise for the development of cancer chemotherapeutic agents. In the last few decades, Schiff bases and their complexes have become well known for their extensive biological potential. In the present study, we examined the antiproliferative effect of a copper (II) complex on HT-29 colon cancer cells. The Cu(BrHAP)2 Schiff base c...

(OFI) contains health-promoting compounds like flavonoids, being the isorhamnetin glycosides the most abundant. We evaluated the effect of OFI extracts with different isorhamnetin glycosides against two different human colon cancer cells (HT-29 and Caco2). The extracts were obtained by alkaline hydrolysis with NaOH at 40 °C during 15, 30 or 60 min. Tri and diglycosides were the most abundant is...

2,4',6-Trihydroxy-4-methoxybenzophenone was isolated from the ethyl acetate fraction of Phaleria macrocarpa (Scheff.) Boerl. fruits. It was found to inhibit cell proliferation in HT-29 human colon carcinoma cell line but caused little damage to WRL-68 normal human liver and MRC-5 normal human fibroblast lung cell lines. The compound was found to sharply affect the viability of HT-29 cells in a ...

EVI1 (Ecotropic Viral Integration site I), which was originally identified as a myeloid transforming gene by means of retroviral insertional mutagenesis in mouse leukemia, encodes a nuclear DNA binding zinc finger protein. The presence of zinc fingers that are able to bind to specific sequences of DNA suggests that EVI1 is a transcriptional regulator; however, except a few, target genes of EVI1...

This study aimed to evaluate the anticarcinogenic activities of aqueous extract of fermented wheat germ with Lactobacillus plantarum dy-1 (LFWGE). The anticarcinogenic activities, including antiproliferative effects and the induction of apoptosis, were studied in human HT-29 colon cancer cells. The 2,6-dimethoxybenzoquinone and total phenol contents in LFWGE were determined by HPLC and the Foli...

Abreu-Martin, Maria T., Andrew A. Palladino, Mary Faris, Nelson M. Carramanzana, André E. Nel, and Stephan R. Targan. Fas activates the JNK pathway in human colonic epithelial cells: lack of a direct role in apoptosis. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G599–G605, 1999.—Fas is expressed constitutively by colonic epithelial cells, and its ligand is expressed by intraepithelia...

BACKGROUND Luteolin is a 3',4',5,7-tetrahydroxyflavone found in various fruits and vegetables. We have shown previously that luteolin reduces HT-29 cell growth by inducing apoptosis and cell cycle arrest. The objective of this study was to examine whether luteolin downregulates the insulin-like growth factor-I receptor (IGF-IR) signaling pathway in HT-29 cells. METHODS In order to assess the ...

The potential chemopreventive properties of the crude extract of Onopordum cynarocephalum were evaluated. Growth inhibition was investigated in FHs74Int human normal intestinal cells and ModeK mouse normal intestinal cell line and in two human colon cancer cells HCT-116 (p53+/+) and HT-29 (p53+/-). The extract was not cytotoxic to FHs74Int cells at concentrations 2-fold higher than the IC50 of ...
