NR4A1 and neoplasm: Accumulating evidence indicates that NR4A1 decreases tumour cell growth by triggering apoptosis signalling in many solid tumours.28, 29, 30 To investigate the underlying mechanism by which the Lnc‐NA‐NR4A1 axis regulates cell growth, apoptosis, migration, and invasion, we determined the expression of proteins involved in apoptosis signalling.
