multicentric reticulohistiocytosis (mrh) is a rare proliferative histiocytic disease of ‎unknown cause with potentially disabling nature. primary manifestations are involvement ‎of skin and joints. the articular destruction can lead to permanent joint deformities. our ‎patient was a 47 year-old woman with bilateral symmetrical polyarthritis and reddish- ‎brown papulonodular cutaneous lesions. t...

in this presentation, we review briefly on biogenesis of peroxisomes with regard to the recent findings on biogenesis. peroxisomes perform a range of various functions as oxidation of very long chain fatty acids, generation and removal of hydrogen peroxide, while peroxisomes have also been implicated in β-oxidation of aromatic and cyclic compounds, synthesis of plasmalogens, isoprenoids, lysine...

Fibrates, such as ciprofibrate, fenofibrate, and clofibrate, are peroxisome proliferator-activated receptor-alpha (PPARalpha) agonists that have been in clinical use for many decades for treatment of dyslipidemia. When mice and rats are given PPARalpha agonists, these drugs cause hepatic peroxisome proliferation, hypertrophy, hyperplasia, and eventually hepatocarcinogenesis. Importantly, primat...

Mevalonate pyrophosphate decarboxylase (MPD) is considered to be a cytosolic protein. Recently, other groups reported that MPD is mostly located in the peroxisomes. In this study, we examined whether the expression of MPD in mice depends on the proliferation of peroxisomes, and whether MPD is predominantly located in the peroxisomes or the cytosol of mice. No increase in the protein level of MP...

purpose: to evaluate the success rate of vitrectomy in giant retinal tears (gtr) and factors influencing it. methods: in an interventional case series, hospital records of 68 eyes of 63 patients operated for grt were reviewed. standard three port vitrectomy plus placement of an encircling band, retinopexy, and internal tamponade was performed for all eyes. possible influencing factors including...

Fibrate class hypolipidemic drugs such as ciprofibrate activate the peroxisome proliferator-activated receptor-alpha (PPARalpha), which is involved in processes including lipid metabolism and hepatocyte proliferation in rodents. We examined the effects of ciprofibrate (50 mg/kg body wt per day for 60 days) on liver gene expression in rats using cDNA microarrays. The 60-day dosing period was cho...

discussions in comparison to the control of wy14643, sandoz58-035, c9 and t11-cla, epa increased the pparα mrna levels (p = 0.024, p = 0.041, p = 0.043, and p = 0.004, respectively), even though, la had no significant effect on the pparα mrna expression (p = 0.489). materials and methods this experimental study investigated the effects of c9, t11-conjugated linoleic acid (c9, t11-cla). alpha li...

we searched for novel chinese hamster ovary (cho) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (pts) of pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (egfp). from mutagenized tkaeg3(1–40) cells, the wild-type cho-k1 stably expressing rat pex2p and of rat pex3p(1–40)-egfp, numerous cell colonies resistant to...
