background: mucopolysaccharidosis type-vi (mps-vi), which is inherited as an autosomal recessive trait, results from the deficiency of n-acetylgalactosamine 4-sulfatase (arylsulfatase b) activity and the lysosomal accumulation of dermatan sulfate. in this study, arsb mutation analysis was performed on three unrelated patients who were originally from the west azerbaijan province of iran. method...

Arylsulfatase B (ARSB; N-acetylgalactosamine 4-sulfatase) is reduced in several malignancies, but levels in melanoma have not been investigated previously. Experiments were performed in melanoma cell lines to determine ARSB activity and impact on melanoma invasiveness. ARSB activity was reduced ~50% in melanoma cells compared to normal melanocytes. Silencing ARSB significantly increased the mRN...

A combination of differential centrifugation and carrier-free continuous electrophoresis is introduced as a new method for the isolation of animal cell organelles. Various buffers were systematically checked in order to find the system which preserves the organelles and gives as well a good separation in the free-flow electrophoresis apparatus. Triethanolamine-acetate buffer (10 mM), pH 7.4 was...
