As the goal of this study was to identify TXNIP expression in brain-derived cells in tissue, immunoblots employing cells extracts from purified microglia, purified endothelial cell, hCMEC/D3 endothelial cell line, human brain-derived astrocytes, and neurons derived from neuronal progenitor cells and differentiated LAN-5 neuroblastoma cells were probed with the four TXNIP antibodies to identify whether there were noticeable differences in specificity for the TXNIP polypeptides expressed by these neural cells. The gene discussed is TXNIP; the disease is neuroblastoma.
