  • Food is a significant source of polycyclic aromatic hydrocarbons (PAHs) to which humans are exposed. In this study, we are analysed 14 PAHs in baked and smoked meats known as major source of PAHs, and defined a correlation between benzo(a)pyrene and pyrene to compare estimating risk from human exposure to PAHs with urinary1-hydroxypyrene.(omitted)

  • Peroxisome proliferator-activated receptors(PPARs) are member of the neuclear hormone receptor superfamiliy of ligand-dependent transcription factors that heterodimerizes with the retinoid X receptor to function as a transcriptional regulator. They are divided into three subtypes(PPAR-$\alpha$, $\beta$ and ${\gamma}$).(omitted)

  • Preclinical test methods for allergenic potential chemicals has been widely used to assess human risks and has been developed. Recently, the murine local lymph node assay (LLNA) has been proposed as a prospective method to identify contact allergens and to replace conventional the guinea pig maximization test (GPMT). The objective of this study was to establish LLNA and to evaluate allergenicity of chemicals by LLNA. (omitted)

  • Tumor cell invasion and metastasis are a complex multistep process that involves the degradation of extracellular matrix proteins by matrix metalloproteinases (MMPs). Tissue inhibitor of metalloproteinase-1 (TIMP-1) acts as a negative regulator of matrix metalloproteinase and thus prevents tumor cell invasion and metastasis by preserving extracellular matrix integrity.(omitted)
