KLF4 and Alzheimer disease: For example, LNC_000854, LNC_001450, LNC_001451, LNC_001887, LNC_002205, LNC_002746, LNC_ 003197, LNC_003206, LNC_003458, LNC_004148, LNC_004514, LNC_004707 and LNC_006482 were identified as ceRNAs of mmu-miR-122-5p, which targets Klf4. The expression of Klf4 was higher in AD mice than in WT mice.
