NR2F1-AS1 and neoplasm: Although several studies have reported that the lncRNA termed NR2F1 antisense RNA 1 (NR2F1-AS1) affects various cellular processes that initiate tumorigenesis and promote tumor progression [24–29], studies reporting the expression and role of NR2F1-AS1 in NSCLC and the mechanisms underlying its pro-oncogenic activities in NSCLC progression are limited.
