Validation of five selected DE lncRNAs performed in triplicate using qRT-PCR. a–e Expression of LOC103692676, LOC102546895, LOC100911992, Ncl-ps1, and LOC103692397 in hippocampus tissues of normal group, sham group, POCD group, and Dex treatment group. Gene expression was normalized to GAPDH transcript levels. Significance was determined using one-way ANOVA. ns no significant, *p < 0.05, **p < 0.01
