LCN2 and stroke disorder: In particular, the three DElncRNAs (CTD-2545M3.2, RP11-24N18.1, and RP11-473C18.7) and four DEGs (LCN2, LAIR2, RPS10, and HBB) that showed the most significant variations between PSA and HC samples were selected for further qPCR verification in the samples from the HC, stroke, PSA, and PSA-T groups.
