To further validate the impact of PTPN14 on the metastatic properties of breast cancer cells, particularly on anoikis resistance, we injected MDA‐MB‐231‐Luc (luciferase) cells overexpressing PTPN14 and their control counterparts into NOD SCID mice via the tail vein (Figure S3J, Supporting Information). This evidence concerns the gene PTPN14 and breast carcinoma.
