To investigate the molecular mechanisms underlying RA-mediated responses in lung endothelial cells, we profiled the gene expression of human pulmonary microvascular endothelial cells (HPMECs) treated with RA or ethanol (EtOH) vehicle control. Whole-genome expression analysis using Affymetrix Human U133 Plus 2.0 GeneChips identified transcriptional changes associated with angiogenesis, wound healing, and signalling pathways relevant to alveolar repair.2026/07/02GSE307491GSM9225532GSM9225510GSM9225521GSM9225520GSM9225531GSM9225530GSM9225518GSM9225529GSM9225517GSM9225528GSM9225527GSM9225516GSM9225515GSM9225526GSM9225514GSM9225525GSM9225513GSM9225524GSM9225523GSM9225512GSM9225511GSM9225533GSM9225522GSM9225519570307491Homo sapiens
