Recent findings suggest that the lncRNA breast cancer anti-estrogen resistance 4 (BCAR4)24 can control GLI family zinc finger 2 (GLI2) gene expression to promote cancer cell migration by interacting with Smad nuclear interacting protein 1 (SNIP1) and serine/threonine-protein phosphatase 1 regulatory subunit 10 (PNUTS). Here, BCAR4 is linked to cancer.
