So far, the ENCORI (The Encyclopedia of RNA Interactomes) website (https://starbase.sysu.edu.cn/) presents the interactions of miRNA-target gene (miR-17-5p – PPARδ) in NSCLC, and based on it the co-expression profile of PPARδ and miR-17-5p in 512 lung adenocarcinoma (LUAD) samples with p = 0.981 and in 475 lung squamous cell carcinoma (LUSC) samples with p = 0.00847 was assessed. The gene discussed is PPARD; the disease is non-small cell lung carcinoma.
