A study of ceRNAs in the Alzheimer’s disease showed that BACEl-AS (BACEl-antisense, BACEl-AS) could be an endogenous competitive RNA to target miRNA (mir01273, mir-1285, and mir-3064) and activate the transcription of SERFla (small EDRK-rich factor 1A, SERF1a). The gene discussed is SERF1A; the disease is early-onset autosomal dominant Alzheimer disease.
