The promoter of CDKN1A antisense DNA damage-activated RNA (lncRNA-PANDAR) at 6p21.2 primarily regulates responses to DNA damage, is upregulated in CRC tissues (Lu et al., 2017), and is significantly associated with poor overall survival (Lu et al., 2017; Han et al., 2019; Li X. et al., 2017). Here, CDKN1A is linked to colorectal carcinoma.
