To determine the role of 14-3-3 in colorectal cancer apoptosis induced by nonsteroidal anti-inflammatory drugs (NSAIDs), we evaluated the effects of sulindac on 14-3-3epsilon protein expression in colorectal cancer cells. Sulindac sulfide inhibited 14-3-3epsilon proteins in HT-29 and DLD-1 cells in a time- and concentration-dependent manner. Sulindac sulfone at 600 mumol/L inhibited 14-3-3epsil...

Disrupted apoptosis not only confers a survival advantage to cancer cells but also causes resistance to chemotherapies. Therefore, inducing cell apoptosis has become a promising strategy for anticancer treatment. Patrinia scabiosaefolia (PS) has long been used to clinically treat various types of malignancies including colorectal cancer (CRC). However, the precise mechanism of its tumoricidal a...

Riceberry rice bran is the part of that has been scrubbed out during coloring process. There are various health benefits to be gained from foods with a high protein content. This work aimed study effect hydrolyzed riceberry extracts on colon cancer cell lines compared normal cells. The MTT assay result showed our extract lower cytotoxicity effects cells (PCS-201-010, IC50 = 6745 µg/mL) and grea...

Flavonoids are polyphenolic compounds that occur ubiquitously in plants. They are discussed to represent cancer preventive food components in a human diet that is rich in fruits and vegetables. To understand the molecular basis of the putative anticancer activity of flavonoids, we investigated whether and how the core structure of the flavones, 2-phenyl-4H-1-benzopyran-4-one (flavone) affects p...

To examine the effect of hydrophobicity on the anticancer activity of 1,4-naphthoquinone derivatives, a series of compounds bearing a 2-O-alkyl-, 3-C-alkyl- or 2/3-N-morpholinoalkyl group were synthesized and evaluated for their anticancer activity against five human cancer cell lines in vitro. The cytotoxicity of these derivatives was assayed against HT-29, SW480, HepG2, MCF-7 and HL-60 cells ...

objective: it is well-known that all living cells emit ultra-weak photon emission (upe), which is due to byproducts of chemical reactions in cell metabolisms. it has been shown that reactive oxygen species (ros) in the cells enhances the upe intensity. the magnitude of such upe is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...

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...

The nonsteroidal anti-inflammatory drug sulindac is known to inhibit chemical carcinogenesis in rodent models and cause regression of adenomas in patients with adenomatous polyposis coli. Sulindac is a prodrug that is metabolized to a pharmacologically active sulfide derivative that potently inhibits prostaglandin synthesis. Recent studies, however, have shown that a sulfone derivative of sulin...

Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...

Background: Lactobacillus and Bifidobacterium species are among the probiotics discussed due to their anti-cancer effects in the treatment of colorectal and breast cancers in recent studies. The aim of this study was to investigate the anticancer effect of Familact, a commercial probiotic capsule containing seven bacterial strains (L. casei, L. acidophilus, L. rhamnosus, L. bulgaricus, B. breve...
