MALAT1 and triple-negative breast carcinoma: found that JAG1 can promote the secretion of exosomes by triple-negative breast cancer cells and upregulate the expression level of LncRNA MALAT1 in the exosomes, and LncRNA MALAT1 promotes macrophage adhesion, migration and osteoclast differentiation by targeting the inhibition of miR-26a-5p [73].
