| Research Abstract |
This study was undertaken in order to elucidate pathogenesis of Zellweger syndrome (ZS), in which peroxisomes do not exist in cells. The following results were obtained 1) The defect of enzymes involved in peroxisomal -oxidation was recognized in cells from the patients with ZS. 2) The defect of peroxisomal membrane proteins of 70 KD, 26 KD and 22 KD was found in cells from the patient with ZD. 3) The enzymes involved in mitochondrial -oxidation were all intact in ZS cells. 4) It was suggested that the peroxisomal enzymes can be synthesized in ZS cells, but they are rapidly decomposed in cytoplasma because of the absence of peroxisomes.
