To further evaluate the influence of IGF2BP2 on LINC01133-induced proliferation and metastasis of ER+ breast cancer, IGF2BP2 was transiently transfected into LINC01133-upregulated cells, and siRNA targeting IGF2BP2 was transiently transfected into LINC01133-downregulated cells. Here, IGF2BP2 is linked to breast carcinoma.
