PURPOSE: An intestinal microbial enzyme complex and a method for preparing the same are provided to ensure anti-allergic, anti-inflammatory, anticancer, and anti-aging effects in vitro. CONSTITUTION: An intestinal microbial enzyme complex contains Megasphaera elsdenii, Parabacteroides distasonis, Klebsiella pneumoniae, and Eubacterium rectale in a ratio of 1:1:1:1. The complex has an enzyme activity to one or more substrates selected from the group consisting of p-nitrophenyl-beta-Dglucuronide, p-nitrophenyl-beta-D-xylopyranoside, nitrophenyl-alpha-L-rhamnopyranoside, and pnitrophenyl-beta-D-glucopyranoside.
Abstract:
The present invention relates to a biomarker for screening drugs causing nephyrotoxicity and side effects and to a method for screening drugs causing nephyrotoxicity and side effects using the same and, specifically, to a biomarker in which gene expression is commonly increased or decreased for various drugs causing nephyrotoxicity and to a method for screening drugs causing nephyrotoxicity and side effects using the same. The fact that pyruvate kinase isozyme M2 (PKM2) and eukaryotic elongation factor 1-gamma (EEF1G) are effectively increased in a culture medium of human kidney epithelial cell in which nephyrotoxicity is caused by drugs is confirmed, and such result can be effectively used for assessing toxicity using the human kidney epithelial cell. The biomarker of the present invention can be effectively used for monitoring and deciding drugs or chemicals having risks of novel nephyrotoxicity and side effects and can be used as a tool for investigating a mechanism which generates nephyrotoxicity.

PURPOSE: A method for predicting drug response to celecoxib using the genotype of cytochrome p450 2C9 (CYP2C9) gene is provided to analyze the genotype of CYP2C9 gene for predicting drug response to celecoxib and to present a proposal on drug approvals in consideration of Korean pharmacogenomics. CONSTITUTION: A method for analyzing the genotype of CYP2C9 gene for predicting drug response to celecoxib comprises the steps of: acquiring exon 2 and exon 7 of a gene encoding CYP2C9 from genomic DNA and sequencing exon 2 and exon 7; detecting single nucleotide polymorphisms (SNPs) in each determined base sequence, wherein 101^th base (T) of sequence number 1 (exon 2) in CYP2C9 is substituted with C (CYP2C9*13) and 114^th base (A) of sequence number 2 (exon 7) in CYP2C9 is substituted with C (CYP2C9*3); and determining if the genotype of CYP2C9 belongs to the extensive metabolizer (EM) group or intermediate metabolizer (IM) group using the detected SNP. A method for predicting drug response to celecoxib by each CYP2C9 genotype comprises the steps of: orally administering 120-250 mg of celecoxib to each of the EM group and the IM group; and comparing the area under the concentration-time curve (AUC) by each genotype and computing a dosage of celecoxib by each genotype.
