  • Since its first release in 2007, the National Institute of Food and Drug Safety Evaluation (NIFDS) has provided pharmacogenomic and comparative information specific to Koreans to allow regulatory reviewers and researchers to adapt their working practices to pharmacogenomics. The highlights of this year's additions include "Drug Information", "Gene Information" and "Pharmacogenomic information in the drug labels" sections. These new additions provide information on 737 genes, 719 drugs and pharmacogenomic data of the labels or relabels of 253 approved drugs as of November 2008. The latest version of the Korean Pharmacogenomic Database (KPD, release 2.0) has expanded significantly since its previous release. More SNP and haplotype information has been added to the database with the latest version of the KPD containing approximately four times as many SNPs and haplotypes than the previous version (719 vs. 152, and 30 vs. 7 respectively). Through the "SNP" and "Haplotype" sections, the KPD provides unique Korean SNP and haplotype information as well as comparative information of other populations (Japanese, Chinese, European, African) to offer a range of pharmacogenomic data that can help reviewers and the public understand pharmacogenomic information. The quality and quantity of information in the KPD has also been improved considerably. This data can be found at: http://www.nitr.go.kr/nitr/contents/m134700/view.do/.

  • For the safety evaluation of adenovirus-mediated gene therapy. we have investigated gene and protein expression after transduction of adenoviral vector (Ad5CMV-p16) which contains tumor suppressor gene. p161NK4$\alpha$ in human non-small cell lung cancer (A549) cells. We compared the differential gene expression level in the A549 cells treated with Ad5CMV (null type) and Ad5CMV-p16 virus. respectively. by using cDNA membrane chip and oligonucleotide chip.

  • Transgenic mouse models have been introduced and accepted by regulatory bodies as an alternative to carcinogenicity assay models to predict and evaluate chemical carcinogens. The recent research outcomes in transgenic mouse models have made progressive advances in the understanding of chemical carcinogenesis and the evaluation of potential human carcinogens. However, these models still remain to be insufficient assay systems although the insufficiencies have been recognised and are being resolved. Based on up to date information from literature, this review article intends to understand currently accepted transgenic mouse models, issues arising from study design, interpretation of the study, results of validation project and their cancer prediction rate, and further perspectives of cancer assay models from the regulatory view point.

  • A simple and reliable reverse phase HPLC method was developed to determine pharmacologically active marker compounds of Epimedii Herba, Atractylodis Rhizoma Alba, and Polygalae Radix. The stability test of water-extracts of the three natural medicines has been evaluated for six months. However, no significant changes in the content of the marker compounds of each extract were observed during the time of investigation.

  • Stem cell-based products (SCPs) are an emerging field of veterinary medicine that focuses on the regeneration, repair, or replacement of damaged tissues or organs. However, there are some issues in applying the traditional regulatory guideline for the approval of SCPs as veterinary medicinal products. This article describes the positions of Korea, US, and EU regarding SCPs, and compares the regulatory guidelines of each country for their safety evaluation. Although there are some differences in the regulatory guidelines, similar considerations in identifying the quality of SCPs and their safety has adopted. Overall, these guidelines need to be harmonized among countries.

  • China is an Asia country with population more than 1,200 millions. According to the national registration, the number Q[ chemicals commonly used in China reaches 80,000, and the number of chemicals produced in China is more than 30,000, about 10% of which has been evaluated for safety and has the toxicological data. Most of the chemicals still need safety evaluation and a part of chemicals need a renewed evaluation. At present. the information techniques and telecommunication network are develop-ing widely and intensively. It is used not only in different institutions and enterprises, but also in many governmental sectors in my country. Here is the introduction of the situation of information network on chemical safety with toxicological data and the work done by different institutions and governmental sectors in China.

  • The National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) provides validation support for US Federal agencies and the US Tox21 interagency consortium, an interagency collaboration that is using high throughput screening (HTS) and other advanced approaches to better understand and predict chemical hazards to humans and the environment. The use of HTS data from assays relevant to the estrogen receptor signaling data pathway is used as an example of how HTS data can be combined with computational modeling to meet the needs of US agencies. As brief summary of US efforts in the areas of biologics testing, acute toxicity, and skin sensitization will also be provided.
