PG - 451-458 LID - 10.1038/s41434-020-0142-z [doi] AB - RNA polymerase III (Pol III) promoters express short non-coding RNAs and have been adopted for expression of microRNA, interference RNA, and CRISPR single guide RNA (sgRNA). Vectors incorporating H1 and U6 Pol III promoters are being applied for therapeutic genome editing, including multiplexed CRISPR/Cas9 effects. We report a nucleosome-depleted, minimal U6 promoter, which when embedded within lentiviral long terminal repeat (LTR) regions, supports high level transcriptional activity. Furthermore, duplex minimal H1 & U6 promoters transcribed dual sgRNAs for simultaneous disruption of T cell receptor (TCR) and human leukocyte antigen (HLA) molecules, supporting efficient generation of 'universal' CAR T cells.
