Abstract
BACKGROUND Researchers are more and more concerning the safety of fetus or offspring derived from assisted reproductive technology (ART) treatment. As the placenta is a critical organ that sustains and protects the fetus, we hypothesize that altered global gene expression of the placenta subjected to ART manipulation may reflect changes associated with ART procedures and subsequently causal related to offspring health. METHODS Three term placenta samples were obtained from patients undergone in vitro fertilization and embryo transfer due to oviductal factors only. Other three control placentae were from those underwent normal pregnancy. A GeneChip Affymetrix HG-U133 Plus 2.0 Array was utilized to analyze the genes. Using qRT-PCR we certified microarray data from 10 dysregulated genes. Five genes were localized precisely in the placenta as per immunohistochemistry. RESULTS Twenty-six differentially expressed genes were identified in the ART-treated placentae: 17 up-regulated; 9 down-regulated. Eighteen of these were classified into six groups according to critical placental function: immune response; transmembrane transport; metabolism; oxidative stress; cell differentiation; and other functions. Genes involved in immune response, such as ERAP2 and STAT4, and those regulating cell differentiations, such as MUC1, were discerned to be differentially expressed. These gene products were expressed in the placental villus tissues, either in the cytoplasm or in the membrane of syncytiotrophoblastic cells. CONCLUSION To our knowledge, this is the first study in comparing differentially expressed genes in placentae from patients undergone ART treatment vs. those underwent normal pregnancy. Abnormal profiles of critical placental functioning genes, such as ERAP2, STAT4 and MUC1, may be valuable biomarkers to understand how the placenta affects fetal development and ART-derived offspring's health problems.

Abstract
Rh/SiO(2) model catalyst surfaces are prepared under ultra-high vacuum conditions and examined in situ using scanning tunneling microscope and CO infrared reflection absorption techniques, to quantify the number and kinds of active Rh surface sites available for kinetic reaction (CO oxidation) as a function of Rh particle size. The results are compared against CO desorption measurements and elevated pressure CO oxidation reaction kinetics, to evaluate the extent of the correlation between the low and elevated pressure site characterization techniques. Data demonstrate that estimates of Rh active sites exhibit good agreement between the characterization methods and illustrate the utility of low pressure surface science characterization techniques in understanding elevated pressure reaction kinetics on model catalyst surfaces.

Abstract
1. The stereoselective metabolism of ethofumesate (ETO) and its enantiomers in rabbit and rat liver microsomes have been studied by chiral high-performance liquid chromatography (HPLC) method. Two metabolites were detected in both liver microsomes in the presence of beta-nicotinamide adenine dinucleotide phosphate (NADPH). 2. The T(1/2) of (+)-ETO and (-)-ETO in rabbit liver microsomes were 12.2 and 4.7 min of rac-ETO and 25.9 and 6.7 of ETO enantiomers. However, the T(1/2) of (+)-ETO and (-)-ETO in rat liver microsomes were 5.3 and 5.9 min of rac-ETO and 7.8 and 10.6 of ETO enantiomers. The stereoselective selectivity is similar to the in vivo study. 3. After incubation of ETO enantiomers, stereoselectivity was present in the formation of ETO-OH enantiomer in rabbit liver microsomes, but stereoselectivity was not evident in rat liver microsomes. 4. There was no chiral inversion from the (+)-ETO to (-)-ETO or inversion from (-)-ETO to (+)-ETO in both rabbit and rat liver microsomes.

Abstract
Furin, a proprotein convertase (PC), is ubiquitously expressed and implicated in many physiological and pathological processes. This study is aimed to identify the role of furin in human trophoblast invasion and migration. Furin was found to be highly expressed in placental villi of both rhesus monkeys and human beings during early pregnancy. Specifically, furin was found in trophoblast column and trophoblast shell, regions where highly invasive cytotrophoblast cells invade the maternal decidua during human placentation. To determine whether furin plays any role in trophoblast invasion and migration, we employed human extravillous HTR8/SVneo cells in Matrigel invasion and transwell migration assays. Knocking-down furin expression by siRNA significantly inhibited invasion and migration of HTR8/SVneo cells (P<0.01), with corresponding decrease of matrix metalloproteinase-9 (MMP-9) activities. In contrast, over-expression of furin markedly increased cell invasion and migration (P<0.01), accompanied by significant increase of MMP-9 activities. Furthermore, furin siRNA significantly increased the levels of both tissue inhibitors of MMPs (TIMP)-1 and -2. Our results suggest that furin may play an important role in the invasion and migration of human trophoblast cells during early pregnancy.

Abstract
The Krüppel-like factor 5 (KLF5) is a zinc-finger transcription factor promoting cell proliferation, cell-cycle progression and survival. A high expression level of KLF5 mRNA has been shown to be associated with shorter breast cancer patient survival. However, the mechanism of KLF5 action in breast cancer is still not clear. In this study, we found that both KLF5 and its downstream gene fibroblast growth factor binding protein 1 (FGF-BP) are co-expressed in breast cell lines and primary tumors. Manipulation of the KLF5 expression can positively regulate the FGF-BP mRNA and protein levels in multiple breast cell lines. In addition, the secreted FGF-BP protein in the conditional medium is also regulated by KLF5. Furthermore, we demonstrated that KLF5 binds and activates the FGF-BP promoter through a GC box by luciferase reporter, oligo pull down and chromatin immunoprecipitation (ChIP) assays. When FGF-BP is depleted by siRNA, KLF5 fails to promote cell proliferation in MCF10A, SW527 and TSU-Pr1. We further demonstrated that overexpression or addition of FGF-BP rescues the KLF5-knockdown-induced growth arrest in MCF10A cells. Finally, KLF5 significantly promotes MCF7 breast cancer cell xenograft growth in athymic nude mice. These findings suggest that KLF5 may promote breast cancer cell proliferation at least partially through directly activating the FGF-BP mRNA transcription. Understanding the mechanism of KLF5 action in breast cancer may result in useful diagnostic and therapeutic targets.
