We investigated the biological role of thymidine phosphorylase (TP), an angiogenic factor, in gastric cancer cell migration and invasion and explored a therapeutic approach for high TP-expressing tumors using TP enzymatic inhibitor (TPI) and rapamycin. We established TP cDNA overexpressing gastric cancer cell lines (MKN-45/TP and YCC-3/TP) and did invasion(More)
OBJECTIVE To evaluate the dose effect of recombinant mouse granulocyte-macrophage colony-stimulating factor (rmGM-CSF) or brain-derived neurotrophic factor (BDNF) in culture medium on the development of in vitro fertilized mouse embryos. METHODS Mature oocytes were retrieved from superovulated female BDF1 mice and inseminated by sperm from male BDF1 mice.(More)
OBJECTIVE To investigate fertilization and embryo quality of dysmorphic mature oocytes with specific morphological abnormalities obtained from intracytoplasmic sperm injection (ICSI). METHODS The fertilization rate (FR) and embryo quality were compared among 58 dysmorphic and 42 normal form oocytes (control 1) obtained from 35 consecutive ICSI cycles,(More)
OBJECTIVES To determine whether the kappa opioid receptor agonist U-50,488H, a benzacetamide derivative of the cyclo-hexane-1,2-diamine analgesics, may be a useful molecular probe to define the structural requirements of this class of drugs for cardiac sodium channel blockade. ANIMALS AND METHODS The electrophysiological effects of U-50,488H were compared(More)
Advanced gastric cancer is one of the most aggressive gastrointestinal malignancies, and ADAM (A disintegrin and metalloproteinase)-9 is a cell-surface membrane glycoprotein with oncogenic properties that is overexpressed in several cancers. Herein, we investigated the biologic mechanism of ADAM9 in the progression, proliferation, and invasion of gastric(More)
Spiradoline, an arylacetamide kappa (kappa) opioid receptor agonist, produced a potent tonic block of rat neuronal (EC(50)= 34+/-5 microM) and heart (EC(50)= 183+/-13 microM) sodium channels and also blocked IFMQ3 mutant neuronal sodium channels (EC(50)= 130+/-34 microM) that lack fast inactivation when expressed in Xenopus oocytes. Spiradoline produced a(More)
OBJECTIVE Smoking has been reported to harm nearly every organ of the body, but conflicting results have been reported regarding the effects of smoking on assisted conception. In this prospective cohort study, we aimed to investigate the prevalence of positive urinary cotinine tests in infertile couples and whether cotinine positivity was associated with(More)
OBJECTIVE The hereditary nonpolyposis colorectal cancer is inherited syndrome characterized by the development of cancers in various organ system; these includes colorectum, endometrium, and less frequently, small bowel, stomach, urinary tract, ovaries, and brain. We aimed to investigate the clinicopathologic characteristics of hereditary nonpolyposis(More)
