compared to normal prostate cells or stroma, in malignant epithelium, expression of ARSB and Dickkopf Wnt Signaling Pathway Inhibitor DKK3 declines, and expression of galactose-6-sulfate-sulfatase and Wnt signaling targets increases
Manually annotated by BRENDA team
ARSB is extensively expressed and distributed in the entire spinal cord. Expression in anterior horn of gray matter is significantly higher than that in the posterior horn of gray matter and significantly higher than that in the central canal. ARSB is mainly distributed in the microglia and neuron cells in the wild-type mice

differences in distribution, intensity, and pattern of ARSB staining among normal colon, adenomas, and adenocarcinomas, overview. Distinctive, intense luminal membrane staining is present in the normal epithelial cells but reduced in the malignancies and less in the grade 3 than in the grade 1 adenocarcinomas. ARSB enzymatic activity is significantly greater in normal than in malignant tissue, detailed overview
