From: High D-glucose levels induce ACE2 expression via GLUT1 in human airway epithelial cell line Calu-3
Immunofluorescence analysis of ACE2 expression in Calu-3 cells. The cells were treated with normal D-glucose (NG), high D-glucose (HG), or HG and 100 nM of glucose transporter 1 inhibitor (BAY-876) for 72 h. Green color indicates ACE2 expression, which was enhanced by HG and suppressed by BAY-876 in Calu-3 cells. Nuclei are stained in blue with DAPI. Scale bar, 100 μm
