We recently uncovered the role of lncRNA-HAL in promoting the stemness in breast cancer cells; the action of lncRNA LINC00052 in the suppression of migration, as well as the role of LncMat2B in the induction of breast cancer cell invasiveness using in vivo xenotransplantation assays in zebrafish (36, 107, 129). Here, HAL is linked to breast carcinoma.
