A number of studies have recently indicated that numerous lncRNAs are associated with breast cancer progression, including GAS5 (Mourtada-Maarabouni et al., 2009; Zheng et al., 2020), H19 (Adriaenssens et al., 1998), HOTAIR (Rinn et al., 2007), MALAT1 (Loi et al., 2007), NEAT1 (Silva et al., 2011), UCA1 (Wang et al., 2008), XIST (Benoît et al., 2007), and BCAR4 (Peng et al., 2021). Here, UCA1 is linked to breast cancer.
