Peptide of Trichinella spiralis infective larval extract that harnesses growth of human hepatoma cells

ABSTRACT: This project aimed to explore novel anticancer therapeutics from products of parasite since several data related to benefits from the T. spiralis infection have been documented. We validated antitumor activity of T. spiralis infective larval extract and extricate the parasite-derived-antitumor peptide. We found that larval extract exerted antitumor activity to three types of carcinoma cells including hepatocellular carcinoma HepG2, ovarian cancer SK-OV-3, and lung adenocarcinoma A549. Interestingly, it displayed the most antitumor effect to HepG2 cells. Using proteomic and bioinformatic approaches, three putative anticancer peptides were identified from T. spiralis infective larval extract. One of these peptides showed a dose-dependent-anti-HepG2 effect by inducing ROS accumulation, leading to inhibition of the cell proliferation. Our data indicate potential application of the larval extract-derived antitumor peptide as a complementary agent for human hepatoma treatment and highlight a positive aspect of parasite apart from its deleterious effect.

Transcript Level Expression Profiling: anticancer pathways of Smilax Glabra rhizome extract (SW) [HepG2 cells]

Project description:To find the possible signaling pathways which contribute to the anticancer effect of SW-treated HepG2 cells Global gene expression profiling is an ideal technique to obtain useful clues for exploration of the anticancer mechanism of SW. Through comparing microarray results between solvent- and SW-treated cells, differentially expressed genes were obtained (>1.5 fold). The microarray results were validated using real-time RT-PCR. We used the KEGG database, STRING database and GO database for further ananlysis, and therefore got the possible signaling pathways underlying the anticancer effect of SW. We analyzed total RNA samples of solvent- and SW-treated HepG2 cells using the Affymetrix Human Gene 1.0 ST platform. No techinical replicates were performed.

Transcriptome sequencing of Strongyloides ratti

Project description:Strongyloides ratti is a common gastro-intestinal parasite of the rat. The adult parasites are female only, about 2mm long and live in the mucosa of the small intestine. These parasites produce eggs that pass out of the host in its faeces. In the environment infective larval stages develop either directly or after a facultative sexual free-living adult generation. Infective larvae infect hosts by skin penetration.S. ratti is the laboratory analogue of the parasite of humans, S. stercoralis. S. stercoralis is a wide-spread parasite of humans, occurring principally in the tropics and sub-tropics: some 100-200 million people are infected worldwide. Infection of immunosuppressed individuals can result in disseminated strongyloidiasis, in which worms occur throughout the body. This can be fatal unless anti-Strongyloides therapy is given. Other species of Strongyloides parasitise a wide range of vertebrates. As part of the Strongyloides ratti genome project we are profiling the transcriptome of the parasite across its life cycle using RNA-Seq.. This data is part of a pre-publication release.

DNA methyltransferase inhibitor zebularine inhibits human hepatic carcinoma cells proliferation and induces apoptosis.

Project description:Hepatocellular carcinoma is one of the most common cancers in world wide. During tumorigenesis, tumor suppressor and cancer-related genes are commonly silenced by aberrant DNA methylation in their promoter regions. Zebularine [1-(β-ᴅ-ribofuranosyl)-1,2-dihydropyrimidin-2-one] acts as an inhibitor of DNA methylation and exhibits chemical stability and minimal cytotoxicity both in vitro and in vivo. In this study, we explore the effect and possible mechanism of action of zebularine on hepatocellular carcinoma cell line HepG2. Here, we demonstrated that zebularine exhibited antitumor activity on HepG2 cells by inhibiting cell proliferation and inducing apoptosis. Zebularine treatment down-regulated CDK2 and phosphorylation of retinoblastoma protein (RB), and up-regulated p21WAF/CIP1 and p53. We also found that zebularine treatment up-regulated phosphorylation of p44/42 MAPK. These results suggest that p44/42 MAPK pathway play a role in zebularine induced cell cycle arrest by regulating activity of p21WAF/CIP1 and Rb. Furthermore, we found that zebularine induced apoptosis. Although proapoptotic protein Bax levels were not affected, antiapoptotic protein Bcl-2 level was down-regulated with zebularine treatment. The data in the present study suggest that the action of the double-stranded RNA-dependent protein kinase (PKR) is involved in inducing apoptosis with zebularine. These results provide a novel mechanism of zebularine-induced cell growth arrest and apoptosis in hepatocellular carcinoma. Three each independent batches of zebuluarine-treated and control HepG2 cells were subjected to illumina Human methylation 450K Beadchip analysis.

Modulation of gene expression induced by supercritical fluid rosemary extract in colon cancer cells

Project description:Supercritical rosemary extract (containing 16.90% carnosic acid, 1.90% carnosol and 13.59% volatile compounds) showed antitumor activity on colon cancer cells in vitro. We treated colon cancer cells with the extract and we employed whole genome microarray expression profiling to identify genes potentially involved in its antitumor mechanism of action. We analyzed gene expression of colon cancer SW620 cells after treating during 48h with supercritical rosemary extract at concentrations that cause 50% inhibition of cell viability (30 M-NM-<g/mL), citostatic effect (60 M-NM-<g/mL) and 50% cell death (100 M-NM-<g/mL), in comparison to control cells (0 M-NM-<g/mL). Two independent experiments were performed in triplicate. Each sample is the pool of the triplicates of one of the experiments (a or b) at the indicated concentration.
