Pulmonary arterial hypertension (PAH) is a fatal disease characterized by increased blood pressure in the lung circulation. The prevalence of PAH in the HIV-positive population is dramatically higher than that in the general population. While HIV-1 Group M Subtype B is the most prevalent subtype in western countries, the majority of HIV-1 infections in eastern Africa and former Soviet Union countries are caused by Subtype A. Research on vascular complications in the HIV-positive population in the context of subtype differences, however, has not been rigorous. Much of the research on HIV has focused on Subtype B, and information on the mechanisms of Subtype A is nonexistent. The lack of such knowledge results in health disparities in the development of therapeutic strategies to prevent\/treat HIV complications. The present study examined the effects of HIV-1 gp120 of Subtypes A and B on human pulmonary artery endothelial cells by performing protein arrays. We found that the gene expression changes caused by gp120s of Subtypes A and B are different. Subtype A is a more potent downregulator of perostasin, matrix metalloproteinase-2, and ErbB than Subtype B, while Subtype B is more effective in downregulating monocyte chemotactic protein-2 (MCP-2), MCP-3, and thymus- and activation-regulated chemokine proteins. This is the first report of gp120 proteins affecting host cells in an HIV subtype-specific manner, opening up the possibility that complications occur differently in HIV patients throughout the world.<\/jats:p>","DOI":"10.3390\/ijms24043536","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T02:56:13Z","timestamp":1675997773000},"page":"3536","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["gp120 Envelope Glycoproteins of HIV-1 Group M Subtype A and Subtype B Differentially Affect Gene Expression in Human Vascular Endothelial Cells"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6575-9275","authenticated-orcid":false,"given":"Andrew J.","family":"Suh","sequence":"first","affiliation":[{"name":"Department of Pharmacology and Physiology, Georgetown University Medical Center, Washington, DC 20007, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dante I.","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Physiology, Georgetown University Medical Center, Washington, DC 20007, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergiy G.","family":"Gychka","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy, Bogomolets National Medical University, 01601 Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tinatin I.","family":"Brelidze","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Physiology, Georgetown University Medical Center, Washington, DC 20007, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6689-0497","authenticated-orcid":false,"given":"Yuichiro J.","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Physiology, Georgetown University Medical Center, Washington, DC 20007, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"288","DOI":"10.1016\/j.cjca.2019.01.005","article-title":"Pulmonary hypertension in HIV","volume":"35","author":"Basyal","year":"2019","journal-title":"Can.
