To identify lncRNAs that may play a role in the diabetes-impaired angiogenesis in ECs, we examined RNA sequencing (RNA-seq) data sets from human ECs subjected to high glucose (HG) (19) (GSE135357), TNF-α (20) (GSE163433), and hypoxia (2% O2) (21) (GSE136912), respectively. The gene discussed is TNF; the disease is diabetes mellitus.
