Objectives: The present study is to investigate the effect of quercetin on cisplatin-induced growth inhibition, apoptosis and nuclear factor-kappa B (NF-κB) expression in colon cancer HT-29 cells. Methods: HT-29 cells were treated with quercetin, cisplatin or the combination of both. MTT assay was applied to examine cell viability. Transmission electron microscopy and laser scanning confocal mi...
Numerous bioactive compounds have cytotoxic properties towards cancer cells. However, most studies have used single compounds when bioactives may target different pathways and exert greater cytotoxic effects when used in combination. Therefore, the objective of this study was to determine the anti-proliferative effect of γ-tocotrienol (γ-T3) and 6-gingerol (6G) in combination by evaluating apop...
We extracted a glycoprotein from the brown alga Laminaria japonica (LJGP). We previously demonstrated that LJGP induced apoptosis in HT-29 colon cancer cells via the Fasand the mitochondrial signaling pathway, and cell-cycle arrest. However, its effect on the cell membrane remained unknown. In this study, we identified the involvement of matrix metalloproteinase (MMP), integrin, and Epithelial ...
The Houttuynia cordata Thunb (HCT) extract has been used as a traditional Chinese herb medicine and as well as an effective drug for treating allergic inflammation for thousands of years. In this study, we investigated the anti-cancer activity of HCT and its molecular mechanisms in the human colon adenocarcinoma cell line HT-29. HCT inhibited HT-29 cell viability in a dose- and time-dependent m...
Endocan expression is increasingly studied in various human cancers. Experimental evidence showed that human endocan, through its glycan chain, is implicated in various processes of tumor growth. We functionally characterize mouse endocan which is also a chondroitin sulfate proteoglycan but much less glycanated than human endocan. Distant domains from the O-glycanation site, located within exon...
Ropivacaine, a new long-acting local anesthetic, is currently being investigated for the treatment of ulcerative colitis. In view of the increased incidence of dysplasia and neoplasia associated with ulcerative colitis, it is important that the medical treatment of these patients does not stimulate cell proliferation further. This study was performed to evaluate the effect of ropivacaine on the...
BACKGROUND Colon cancer is the third most common cancer in the world, and its metastasis and drug resistance are challenging for its effective treatment. The PI3K/Akt/mTOR pathway plays a crucial role in the pathogenesis of colon cancer. The aim of this study was to investigate the targeting of PI3K in colon cancer cells HT-29 and HCT-116 in vitro. METHODS In HT-29 and HCT-116 cells, BEZ235, ...
BACKGROUND Three-dimensional (3-D) culture systems that simulate the tumor extracellular microenvironment may be appropriate to test cancer cell potential for invasion and tumor cell sensitivity to anticancer drugs. MATERIALS AND METHODS Human PC-3 prostate, A549 colon, HT-29 lung and MCF-7 and MDA-MB231 breast cancer cells were embedded and grown in collagen gel surrounded by a fibrin clot. ...
Necroptosis, also known as "programmed necrosis", has emerged as a critical factor in a variety of pathological and physiological processes and is considered a cell type-specific tightly regulated process with mechanisms that may vary rather greatly due to the change of cell line. Here we used HT-29, a human colon cancer cell line, to establish a necroptosis model and elucidate associated mecha...
Mutation of the adenomatous polyposis coli (APC) gene is associated with the earliest stages of colorectal tumorigenesis and appears to be responsible for the hereditary condition familial adenomatous polyposis (FAP). Evidence indicates that cyclooxygenase-2 (COX-2) is induced and at elevated levels in human colorectal cancers and in the polyps of mouse FAP models. We have used HT-29 cells, a h...
