Project description:Potentilla indica and Melastoma dodecandrum lour are medicinal herbs used in traditional Chinese medicine. We sampled the plants from Nanyang Technological University's herb garden for transcriptomics analysis.
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.
Project description:Panax ginseng C.A. Meyer is one of the most popular medicinal herbs. In order to research the genes that related to the flowering period of ginseng, and find out the antifungal proteins and transcription factors that combat various biotic and abiotic stress, a cDNA sample was prepared from the flowering period ginseng root of a five-year-old plant and sequenced using the Illumina sequencing platform. In this study, we produced nearly 40 million sequencing reads. These reads were assembled into 134,045 contigs using Trinity software (mean size: 282 bp). Based on a similarity search with known proteins, we identified 79,307 sequences with a cut-off E-value of 10-5. Assembled sequences were then annotated using gene ontology (GO) terms, clusters of orthologous group (COG) classifications and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways respectively.
Project description:Berberine is a natural isoquinoline alkaloid found in Chinese medicinal herbs which is active against a variety of microbial infections. To examine the potential effects of berberine on Shigella flexneri, a whole-genome DNA microarray was constructed and transcriptome analysis of the cellular responses of S.flexneri when exposed to Berberine Chloride (BC) was performed.
Project description:Berberine, an isoquinoline alkaloid isolated from many medicinal herbs such as Coptis chinensis, has a wide range of pharmacological effects. Since xenobiotic drug-induced micoRNAs have recently emerged as key regulators in guiding their pharmacological effects and toxicity, we were interested in whether or not micoRNA expression was differentially altered by berberine treatment in liver. Here, we used miRNA microarray to analyze microRNA expression profiles of primary human hepatocytes after berberine chloride treatment or 0.08% DMSO as control.

Project description:Psoriasis is a chronic and complex disease characterized by itching, burning, and soreness with scaly plaques and erythematous lesions. we evaluated the effect of Bojungikki-tang (BJT, Buzhong-Yiqi-Tang in traditional Chinese medicine and Hochu-ekki-to in Kampo medicine) as a combination of medicinal herbs against psoriasis. Network analysis from transcriptomics was used to determine the effective phytochemical constituents of BJT.

Project description:Berberine, an isoquinoline alkaloid isolated from many medicinal herbs such as Coptis chinensis, has a wide range of pharmacological effects including anti-cancer effects. Since xenobiotic drug-induced micoRNAs have recently emerged as key regulators in guiding their pharmacological effects and toxicity, we were interested in whether or not micoRNA expression was differentially altered by berberine treatment in HCC. Here, we used miRNA microarray to analyze microRNA expression profiles of HepG2 human hepatoma cell line after berberine chloride treatment or 0.08% DMSO as control.
Project description:Emodin, a bioactive compound abundant in Chinese medicinal herbs, possesses broad therapeutic potential but raises safety concerns due to conflicting reports of hepatotoxicity. This study investigated the toxicological mechanisms underlying emodin-induced liver injury. We showed that emodin induced dose-dependent cytotoxicity and hepatic injury in HepG2 cells. Moreover, emodin (400 mg/kg) induced hepatotoxicity in mice after administered for three weeks.This study delineates the metabolic detoxification pathways of emodin and elucidates its toxicological mechanisms.
