Alzheimer's disease (AD) occurs when neurons in the memory and cognition regions of the brain are accompanied by an accumulation of the long amyloid beta-proteins of the 39 to 43 amino acids derived from the amyloid precursor protein (APP) by cleavage with beta- and gamma-secretase. An increased production of Abeta-42 by mutation of PS2 genes promotes(More)
The dose and time effect of nine xenobiotics, including 17beta-estradiol, corticosterone, dexamethasone, progesterone, nifedipine, bisphenol A, rifampicin, methamphetamine, and nicotine were investigated, in vitro, using human steroid and xenobiotics receptor (SXR)-binding sites on the human CYP3A4 promoter, which can enhance the linked lacZ reporter gene(More)
The cytochrome P450 enzymes (P450s or CYPs) are a superfamily of hemeproteins that catalyze the monooxygenation of a wide range of endobiotic and xenobiotic substrates. Among members of the superfamily 1, human CYP1B1 (hCY1B1) has been identified in rodent species and in humans [1, 2, 3]. The amino acid sequences in humans, rats, and mice are 80% similar(More)
INTRODUCTION The measurement of flow-mediated dilatation (FMD) via ultrasound has been established as a reliable non-invasive measurement of endothelial function. However, the guidelines mention nothing regarding diurnal variation of FMD. Thus, we investigated the FMD in healthy people and diurnal variation of FMD. METHODS Twenty-five apparently healthy(More)
C57BL/6N is the most widely used inbred mouse strain applied in a wide variety of research areas including cancer, cardiovascular biology, developmental biology, diabetes and obesity, genetics, immunology, neurobiology, and sensorineural research. To compare the fertilization rates of C57BL/6NKorl mice with two commercial C57BL/6N stocks, differences in(More)
Korl:ICR mice, established by the Korean National Institute of Food and Drug Safety Evaluation (NIFDS), are characterized based on their genetic variation, response to gastric injury, and response to constipation inducers. To compare the inhibitory responses of ICR stocks obtained from three different sources to the anticancer drug cisplatin (Cis),(More)
