CCND1 and urinary bladder cancer: LncRNA differentiation antagonizing non-protein coding RNA (DANCR) promotes tumor progression in bladder cancer by activating the signal transducer and activator of transcription 3 (STAT3) pathway and upregulating cyclin D1 (CCND1) expression by interacting with leucine rich pentatricopeptide repeat containing (LRPPRC) protein to stabilize related mRNA [11].
