Project description:Transcriptome profile in human hepatoma HepG2 cells treated with antioxidant-rich Barringtonia racemosa leaf extract
2025-01-24 | E-GEOD-79473 | ExpressionAtlas
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:The leaf extract of T. indica 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 coagulation system, cholesterol biosynthesis, xenobiotic metabolism signaling and antimicrobial response. HepG2 cells were seeded and treated with an IC20 concentration of the methanol leaf extract of T. indica 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 T. indica leaf-treated HepG2 cells were selected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Microarray whole-transcriptome profiling in HCT116 and HepG2 cells treated with Melicope ptelefolia leaf extract reveals transcriptome profles exhibiting anticancer activity

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: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.

Project description:Berberine, an isoquinoline alkaloid isolated from many medicinal herbs such as Coptis chinensis, has a wide range of pharmacological effects. Here, we used gene expression microarray to analyze gene expression profiles of HepG2 human hepatoma cell line after berberine chloride treatment or 0.08% DMSO as control. Comparing gene expression profiles of 40 M-BM-5M-BM--M berberine-treated HepG2 human hepatoma cell line to those of control cells sampled after 4 hours treatment. A 50 mM stock solution of Berberine chloride was prepared in DMSO. Cells were treated with 40 M-BM-5M-BM--M berberine chloride or 0.08% DMSO as control.
