Article Title: gp120 Envelope Glycoproteins of HIV-1 Group M Subtype A and Subtype B Differentially Affect Gene Expression in Human Vascular Endothelial Cells
doi: 10.3390/ijms24043536
Figure Lengend Snippet: gp120 proteins of HIV-1 Group M Subtype A and Subtype B differentially affect prostasin, MMP-2, and ErbB3 expression. Human pulmonary artery endothelial cells were treated with gp120 of HIV-1 Subtype A (gp120A) or Subtype B (gp120B) at 1 nM for 20 h in triplicate. Expression patterns of various proteins were monitored using R&D Human XL Oncology Array. ( A ) Prostasin was found to be higher in gp120B-treated cells, while neighboring E-selectin spots were unchanged. ( B ) MMP-2 was found to be higher in gp120B-treated cells, while neighboring progranulin spots were unchanged. ( C ) ErbB3 was found to be higher in gp120B-treated cells, while neighboring Dkk-1 spots were unchanged. Representative images are shown at the top. Densitometry values from two spots from each array were averaged, and statistical analysis was performed using results from three separate treatments/arrays. Bar graphs represent means ± SEM (N = 3 for all groups). * p < 0.05. ** p < 0.01. *** p < 0.001. The y -axis indicates the mean pixel density of protein spots.
Article Snippet: Cells were treated in triplicate with either the recombinant gp120 of HIV-1 Group M Subunit A (catalog number 40403-V08H, Sino Biological, Inc., Beijing, China), gp120 of HIV-2 Group M Subunit B (catalog number 40404-V08H, Sino Biological), S1 of SARS CoV-2 spike protein (catalog number 40591-V08H, Sino Biological), or S1 of the omicron variant SARS CoV-2 spike protein (catalog number 40591-V08H41, Sino Biological).
