Identification of genes involved in the anti-inflammatory effects of berberine in DNP-activated mouse MC/9 mast cells

ABSTRACT: Atopic dermatitis is a common chronic inflammatory skin disease characterized by infiltration of inflammatory cells, extensive pruritus and a clinical course of symptomatic flares and remissions. Berberine (BER), a naturally occurring isoquinoline alkaloid, has many pharmacological effects including inhibition of protein synthesis, cell cycle arrest, and anti-inflammatory activities. However, a detailed molecular mechanism underling the anti-inflammatory action of BER in inflammatory cells is unclear. Here, to identify genes involved in the anti-inflammatory effects of BER in DNP-activated mouse MC/9 mast cells, global-scale gene expression analysis was carried out using a GeneChip® system.

However, a detailed molecular mechanism underling the anti-inflammatory action of BER in inflammatory cells is unclear. Here, to identify genes involved in the anti-inflammatory effects of BER in DNP-activated mouse MC/9 mast cells, global-scale gene expression analysis was carried out using a GeneChipî system. Mouse MC/9 mast cells were treated with BER (10 microM), DNP (anti-DNP IgE, Sigma; 500 microg/ml) or a combination of BER and DNP. Total RNA samples were prepared from the cells, and quality of the RNA was analyzed using a Bioanalyzer 2100. Gene expression was analyzed by an Affymetrix GeneChipî system with a Mouse Genome 430 2.0 array. Sample preparation for array hybridization was carried out as described in the manufacturerâÂÂs instructions.
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: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.

Comparing miRNA profiles of 40 M-BM-5M-BM--M berberine-treated HepG2 human hepatoma cell line to those of control cells sampled after 2 and 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.
Project description:The anti-diabetes activity of Rhizoma Coptidis was documented in the book âNotes of Elite Physiciansâ written by Hongjing Tao 1500 years ago. Berberine (BBR) is the major isoquinoline alkaloid constituent of the Chinese herb Rhizoma Coptidis, which has the beneficial characteristic of regulating glucose and lipid metabolism and has been extensively used in the treatment of obesity, diabetes and hypercholesterolemia. However, the effect of berberine on specific diabetes treatment targets is unknown. This study was conducted to elucidate the genome-wide gene expression profile in Zucker Diabetic Fatty Rats liver tissues in response to Berberine treatment.
