Using a myriad of in vitro and in vivo models and tools such as single-cell RNA-seq, ChIP-seq and flow cytometry, the authors showed that the deletion of this lncRNA completely abolished the metastasis potential of BC cells, while the overexpression of MALAT1 led to the awakening or reactivation of these dormant BC cells [91]. This evidence concerns the gene MALAT1 and breast cancer.
