GINS1 and breast cancer: We showed that miR‐101‐5p acted as an anti‐tumor miRNA in breast cancer (BrCa) cells through targeting several oncogenic genes (i.e. High Mobility Group Box 3, Epithelial splicing regulatory protein 1, GINS complex subunit 1 (GINS1), Tumor Protein D52, Serine/Arginine‐Rich Splicing Factor Kinase 1, Vang‐like protein 1, and Mago Homolog B).
