H19 and breast cancer: Many studies investigated the oncogenic or tumor suppressor effects of different lncRNAs on BC features, for example, H19 is an oncogenic lncRNA that dysregulates in BC and affects different BC features including proliferation, invasion, migration, cell cycle arrest, apoptosis, metastasis, tumor values, steroid receptor status, tumor size, nodal status, disease-free survival, prognosis, stemness, mesenchymal-to-epithelial transition (MET), epithelial-to-mesenchymal transition (EMT) (Table 1 and Additional file 1: Table S1).
