Recent studies implicate the regulatory function of microRNAs (miRNAs) in oocyte maturation and ovarian follicular development. Differentially expressed miRNAs are found in the plasma of premature ovarian failure (POF) patients and normal cycling women. In this study, miRNA-regulated signaling pathways and related genes were described using Gene Ontology(More)
Nonsynonymous TP53 exon 4 single-nucleotide polymorphism (SNP), R72P, is linked to cancer and mutagen susceptibility. R72P associations with specific cancer risk, particularly hematological malignancies, have been conflicting. Myelodysplastic syndrome (MDS) with chromosome 5q deletion is characterized by erythroid hypoplasia arising from lineage-specific(More)
Placenta-specific protein 1 (PLAC1), a placenta-specific gene, is known to be involved in the development of placenta in both humans and mice. However, the precise role of PLAC1 in placental trophoblast function remains unclear. In this study, the localization of PLAC1 in human placental tissues and its physiological significance in trophoblast invasion and(More)
Serine proteases have been documented to play key roles in uterine matrix turnover and trophoblastic invasion during implantation. Roles of prostasin serine protease in these processes, however, are currently unclear. The present study was first conducted to investigate the colocalization of prostasin and its cognate serpin, protease nexin-1 (PN-1), in(More)
During early pregnancy, an environment of relative low oxygen tension is essential for normal embryonic and placental vasculature. In low-oxygen conditions, the hypoxic-inducible factor-1 (HIF-1), composed of alpha and beta subunits, controls the expression of a number of genes such as vascular endothelial growth factor (VEGF), a key angiogenic factor. The(More)
Cariporide (HOE 642) inhibits the Na+/H+ exchanger and would be expected to reduce lactate accumulation during ischaemia and stimulate lactate/H+ co-transporter upon reperfusion. The aim of this study was to determine the effect of cariporide on lactate production during global ischaemia and release during reperfusion. Guinea-pig hearts perfused in the(More)
Previous studies have demonstrated that the ubiquitin-proteasome pathway plays an important role in embryo implantation. Low molecular mass polypeptide (LMP) 2 and LMP7 are the two subunits of 20S proteasome, which are critical for proteasome activity. To further elucidate the roles of LMP2 and LMP7 in embryo implantation during early pregnancy, we cloned(More)
Taurine, glutamine, glutamate, aspartate, and alanine are the most abundant intracellular free amino acids in human heart. The myocardial concentration of these amino acids changes during ischemia and reperfusion due to alterations in metabolic and ionic homeostasis. We hypothesized that dilated left ventricle secondary to mitral valve disease has different(More)
Corticosteroid-binding globulin (CBG), a non-inhibitory member of the serine proteinase inhibitor (serpin) super-family, is the high-affinity transport protein for glucocorticoids in vertebrate blood. Plasma CBG is a glycoprotein with 30% of its mass represented by N-linked oligosaccharide chains. Its well-characterized steroid-binding properties represent(More)
Transforming growth factor (TGF)-β and activin, members of TGF-β superfamily, are abundantly expressed in the endometrium and regulate decidualization of endometrial stroma. Smad2 and Smad3 are receptor-regulated Smads (R-Smads) that transduce extracellular TGF-β/activin/Nodal signaling. In situ hybridization results showed that Smad3 was highly expressed(More)
