lncRNA profiles in ovarian follicles. a Porcine ovarian follicles (3–5 mm diameter) were classified into healthy follicles (HF) and early atresia follicles (EAF). b Venn diagram of the overlapping lncRNAs in HF and EAF. c Chromosome distribution and expression schema of lncRNAs. The outermost layer represents chromosomes, and the gray dots represent the chromosomes corresponding to each lncRNAs. The red and yellow histograms represent lncRNA expression in HF and EAF, respectively. d Heat map showing differentially expressed lncRNAs (DELs) between the HF and EAF groups. e Validation of the DELs. The expression levels of the DELs in HF and EAF were detected by qRT-PCR. The data are presented as the mean ± SEM of at last three independent experiments. * P < 0.05. ** P < 0.01. *** P < 0.001
