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 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)
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)
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)
SDS-PAGE, Western blot analysis and immunohistochemical staining were used to detect heat shock proteins (HSPs) 60, 70 and 90 in canine transmissible venereal tumor (CTVT). Tissues tested for HSPs included: (1) tissues from different growth phases of CTVT tumors artificially induced in dogs; (2) tissues from other canine tumors; (3) normal dog tissues. Our(More)
Peroxisomal acyl-CoA oxidase (ACOX; EC 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)
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)
