DSCAM-AS1 and breast cancer: Xu et al. (2017) identified a cluster of oncogenic upregulated lncRNAs in BC tissue and that the knockout of DSCAM-AS1, TINCR, or HOTAIR prohibited BC cell proliferation. Currently, several curated databases have archived the known BC-associated factors, such as the Comparative Toxicogenomics Database (CTD) (Davis et al., 2017), Human microRNA Disease Database (HMDD) (Huang et al., 2019), and LncRNADisease (Bao et al., 2019). Although great progress has been made in identifying genetic risk factors of BC, the genetic contribution to BC etiology remains to be elucidated (Skol et al., 2016).
