H19 and breast carcinoma: Wang et al. (2019c) suggested that lncRNA HULC in breast cancer tissues and cell lines paired with miR-6754-5p and upregulated LYPD1 (LY6/PLAUR domain containing 1) gene expression (Wang et al., 2019c). Vennin et al. (2017) demonstrated that oncogenic lncRNA 91H prevents histone and DNA methylation on the maternal allele at the H19/IGF2 (Insulin Like Growth Factor 2) locus (Vennin et al., 2017).
