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.

Project description:Background:We have previously reported anticancer activities of Melicope ptelefolia (MP) leaf extracts on four different cancer cell lines. However, the underlying mechanisms of actions have yet to be deciphered. In the present study, the anticancer activity of MP hexane extract (MP-HX) on colorectal (HCT116) and hepatocellular carcinoma (HepG2) cell lines was characterized through microarray gene expression profiling. Methods:HCT116 and HepG2 cells were treated with MP-HX for 24 hr. Total RNA was extracted from the cells and used for transcriptome profiling using Applied Biosystem GeneChip™ Human Gene 2.0 ST Array. Gene expression data was analysed using an Applied Biosystems Expression Console and Transcriptome Analysis Console software. Pathway enrichment analyses was performed using Ingenuity Pathway Analysis (IPA) software. The microarray data was validated by profiling the expression of 17 genes through quantitative reverse transcription PCR (RT-qPCR). Results:MP-HX induced differential expression of 1,290 and 1,325 genes in HCT116 and HepG2 cells, respectively (microarray data fold change, MA_FC ? ±2.0). The direction of gene expression change for the 17 genes assayed through RT-qPCR agree with the microarray data. In both cell lines, MP-HX modulated the expression of many genes in directions that support antiproliferative activity. IPA software analyses revealed MP-HX modulated canonical pathways, networks and biological processes that are associated with cell cycle, DNA replication, cellular growth and cell proliferation. In both cell lines, upregulation of genes which promote apoptosis, cell cycle arrest and growth inhibition were observed, while genes that are typically overexpressed in diverse human cancers or those that promoted cell cycle progression, DNA replication and cellular proliferation were downregulated. Some of the genes upregulated by MP-HX include pro-apoptotic genes (DDIT3, BBC3, JUN), cell cycle arresting (CDKN1A, CDKN2B), growth arrest/repair (TP53, GADD45A) and metastasis suppression (NDRG1). MP-HX downregulated the expression of genes that could promote anti-apoptotic effect, cell cycle progression, tumor development and progression, which include BIRC5, CCNA2, CCNB1, CCNB2, CCNE2, CDK1/2/6, GINS2, HELLS, MCM2/10 PLK1, RRM2 and SKP2. It is interesting to note that all six top-ranked genes proposed to be cancer-associated (PLK1, MCM2, MCM3, MCM7, MCM10 and SKP2) were downregulated by MP-HX in both cell lines. Discussion:The present study showed that the anticancer activities of MP-HX are exerted through its actions on genes regulating apoptosis, cell proliferation, DNA replication and cell cycle progression. These findings further project the potential use of MP as a nutraceutical agent for cancer therapeutics.

Project description: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.

Project description:The water extract of the leaf of B. racemosa had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the glycolysis, gluconeogenesis and metabolism of xenobiotics. HepG2 cells were seeded and treated with an 50 µg/ml of the water leaf extract of B. racemosa for 24 h. Following this, cells were trypsinized and then preciptated by centrifugation. Cells were washed with phosphate buffer saline (PBS) before total cellular RNA (tcRNA) were extracted from the cells. tcRNA from both untreated and B. racemosa leaf-treated HepG2 cells were selected for RNA extraction and hybridization on Affymetrix microarrays. All experiments were done in triplicate. The microarray analysis was performed on Affymetrix Human Gene 1.0 S.T Array according to the manufacturer's protocol. The gene sets were then subjected to analysis of variance (ANOVA) in the Partek Genomics Suite software to determine significantly expressed genes which was set according to P value less than 0.05 and fold change difference of equal to or greater than 1.5.

Project description:Mi(cro)RNAs are small non-coding RNAs of 18-25 nucleotides in length that modulate gene expression at the post-transcriptional level. These RNAs have been shown to be involved in a several biological processes, human diseases and metabolic disorders. Proanthocyanidins, which are the most abundant polyphenol class in the human diet, have positive heath effects on a variety of metabolic disorders such as inflammation, obesity, diabetes and insulin resistance. The present study aimed to evaluate whether proanthocyanidin-rich natural extracts modulate miRNA expression. Using microarray analysis and Q-PCR, we investigated miRNA expression in HepG2 cells treated with proanthocyanidins. Our results showed that when HepG2 cells were treated with grape seed proanthocyanidin extract (GSPE), cocoa proanthocyanidin extract (CPE) or pure epigallocatechin gallate isolated from green tea (EGCG), fifteen, six and five differentially expressed miRNAs, respectively, were identified out of 904 mRNAs. Specifically, miR-30b* was downregulated by the three treatments, and treatment with GSPE or CPE upregulated miR-1224-3p, miR-197 and miR-532-3p. Therefore, these results provide evidence of the capacity of dietary proanthocyanidins to influence microRNA expression, revealing a new mechanism of action of proanthocyanidins. microRNA profiling of Human hepatocellular liver carcinoma cell line (HepG2) comparing control untreated HepG2 cells with cells treated with grape seed proanthocyanidin extract (100 mg/L, 5h), cacao proanthocyanidin extract (100 mg/L, 5h) or epigallocatechin gallate (50 mg/L, 5h). Two biologival replicates were used for control and treated cells with one replicate per array.
