Immunohistochemical analysis of paraffin-embedded Human kidney tissue using ENT1 Antibody (HY-P81506, 1/500) . The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (PH 6.0)for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Function
NTPDase8, a member of the ectonucleoside triphosphate diphosphohydrolase (E-NTPDase) family, hydrolyzes extracellular nucleoside triphosphates and diphosphates to monophosphates, thereby regulating purinergic signaling[1][2]. Mechanistically, its catalytic activity depends on conserved apyrase regions and requires divalent cations such as Ca2+ or Mg2+ for efficient phosphate bond hydrolysis[1]. NTPDase8 is primarily localized to hepatocyte canalicular membranes, where it modulates bile secretion and extracellular nucleotide concentrations, distinguishing it from NTPDase1-3 that exhibit broader tissue distribution[3][4]. In disease models, NTPDase8 protects against liver ischemia-reperfusion injury by controlling ATP accumulation and mitigating P2 receptor-mediated inflammatory responses in hepatocytes[5]. Compared with related isoforms, NTPDase8 demonstrates selective substrate preference and distinctive kinetic parameters, emphasizing its non-redundant role in hepatic purinergic homeostasis[3][6]. Experimental studies utilizing recombinant expression systems have enabled detailed kinetic characterization, while selective inhibitors such as thienopyrimidine derivatives and sulfamoyl benzamides provide pharmacological tools to probe NTPDase8 activity in vitro[7][8][9]. These inhibitors exhibit isoform-specific binding interactions, allowing differentiation of NTPDase8 activity from other family members and facilitating functional studies in enzymology, liver physiology, and therapeutic screening applications[10][11].
