Glycoconjugates in the epithelial cells of the efferent ductules in the dog were investigated using lectin histochemistry. These ductules connect the extratesticular rete with the epididymis. The epithelium of the ductules consisted both of ciliated and nonciliated cells. Whereas the apical zone of ciliated cells showed selective binding with WGA, SWGA,(More)
Sorafenib is an agent that inhibits vascular endothelial growth factor and is associated with onset or worsening of hypertension in some patients. We conducted a retrospective analysis of whether the development of hypertension during sorafenib treatment of advanced hepatocellular carcinoma could be a predictor of anti-cancer efficacy. The study included 38(More)
Mutation in K-RAS (K-RAS-MT) plays important roles in both cancer progression and resistance to anti-epidermal growth factor receptor (EGFR) therapy in gastrointestinal tumors. Insulin-like growth factor-1 receptor (IGF-1R) signaling is required for carcinogenicity and progression of many tumors as well. We have previously shown successful therapy for(More)
A form of cytochrome P-450, P-450-D3, cross reactive with antibodies to rat P-450d was purified from liver microsomes of polychlorinated biphenyl (PCB)-treated female Beagle dogs to an electrophoretic homogeneity. Judging from the result of sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE), the molecular weight of P-450-D3 was estimated to(More)
Male Fisher rats were fed a diet ad lib. containing eugenol (4-allyl-2-methoxyphenol) to observe its effects on liver drug-detoxifying enzymes such as UDP-glucuronyltransferase (GT), UDP-glucose dehydrogenase (DH) and glutathione S-transferase (GST). Liver weights were not affected significantly by a diet containing 3% eugenol (w/w) for 13 weeks. The(More)
The serum cholinesterase (ChE) isoenzyme in rats shows 6 bands after polyacrylamide gradient gel electrophoresis. The effects of organophosphates (fenthion, chlorpyrifos, diazinon, bromophos, propaphos, haloxon, and DFP) on serum ChE isoenzyme bands were studied in 32 male and 32 female 6-w-old Sprague-Dawley rats. Each organophosphate was randomly(More)
Pancreatic cancer is a highly aggressive malignancy, with <50% patients surviving beyond 6 months after the diagnosis, and thus, there is an urgent need to explore new diagnostic and therapeutic approaches for this disease. Therefore, we conducted microRNA (miRNA) array analysis to detect miRNA molecules potentially associated with pancreatic cancer(More)
Pregnant rats on day 21 of gestation received a subcutaneous injection of paraquat (25 mg/kg). Two hr later, some fetuses of these rats received a subcutaneous injection of prostaglandin E2 (PGE2). The caliber of the ductus arteriosus (DA) of fetuses was measured 1 hr later. The DA of fetuses of paraquat-treated pregnant rats was significantly constricted(More)
