ROCK1 and breast cancer: Results of this research revealed that MiR-145 was transferred to BC cells by AT-MSC-exos, and this increased miR-145 level in breast cancer cells can induce apoptosis and impede breast cancer metastasis by regulating the expression of several genes such Rho-Associated Coiled-Coil Containing Protein Kinase 1 (ROCK1), Erb-B2 Receptor Tyrosine Kinase 2 (ERBB2), Tumor Protein p53 (TP53), and Matrix Metalloproteinase 9 (MMP9) [274, 275].
