Peroxisome proliferators cause a rapid and coordinated transcriptional activation of genes encoding the enzymes of the peroxisomal beta-oxidation pathway in rats and mice. Cis-acting peroxisome proliferator responsive elements (PPREs) have been identified in the 5'-flanking region of H202-producing rat acyl-CoA oxidase (ACOX) gene and in other genes(More)
Between March and July 1997, a devastating outbreak of foot-and-mouth disease (FMD), serotype O, occurred in pigs in Taiwan. A total of 6,147 pig farms with more than 4 million pigs were infected, and 37.7 per cent of the pigs in Taiwan either died (0.18 million pigs) or were killed (3.85 million pigs). The epidemic reached its peak during the fifth week(More)
Peroxisome proliferators cause rapid and coordinated transcriptional activation of genes encoding peroxisomal beta-oxidation system enzymes by activating peroxisome proliferator-activated receptor (PPAR) isoform(s). Since the thyroid hormone (T3; 3,3',5-triiodothyronine) receptor (TR), another member of the nuclear hormone receptor superfamily, regulates a(More)
Peroxisomal genetic disorders, such as Zellweger syndrome, are characterized by defects in one or more enzymes involved in the peroxisomal beta-oxidation of very long chain fatty acids and are associated with defective peroxisomal biogenesis. The biologic role of peroxisomal beta-oxidation system, which consists of three enzymes: fatty acyl-CoA oxidase(More)
Peroxisomal acyl-CoA oxidase (ACOX; EC 1.3.3.6) is the first enzyme of the fatty acid beta-oxidation pathway, which catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs, and it donates electrons directly to molecular oxygen, thereby producing H2O2. The discovery of carcinogenic peroxisome proliferators, which markedly increase the levels of this(More)
The aim of the Second International Swine Cluster of Differentiation (CD) Workshop, supported by the Veterinary Immunology Committee (VIC) of the International Union of Immunological Societies (IUIS), was to standardize the assignment of monoclonal antibodies (mAb) reactive with porcine leukocyte differentiation antigens and to define new antibody clusters.(More)
Canine transmissible venereal tumor (CTVT) grows progressively (P-phase) in the host and then spontaneously regresses (R-phase). The mechanisms behind the transition from the P-to R-phases are not well understood. In this study, in order to determine the proliferation characteristics of CTVT, we evaluated telomerase activity and enumerated nuclear(More)
To test the hypothesis that LDL lacking of initial oxidation may also anticipate an essential role in the progression for atherosclerotic lesions, we studied the in vitro effect of foam cells induced by low density lipoprotein (LDL), oxidized (ox)-LDL or acetyl-LDL on smooth muscle cell (SMC) proliferation. Intraperitoneal macrophages collected from ICR(More)
Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear receptor superfamily that transcriptionally regulate responsive genes by binding to the peroxisome proliferator response elements. Protein(s) interacting with PPAR isoforms (alpha, delta, and gamma) may modulate the PPAR-mediated transcriptional activation. Using a yeast(More)
