It was shown that lncRNA DLX6‐AS1 (DLX6 Antisense RNA 1) formed a DNA–RNA triplex structure with the promoter of the DLX6 transcription factor via recruitment of P300/E2F1 (E1A Binding Protein P300) acetyltransferase in endometrial cancer cells (H. Zhao & Xu, 2020). This evidence concerns the gene DLX6 and endometrial cancer.
