Fig. 4From: Identification of MFGE8 and KLK5/7 as mediators of breast tumorigenesis and resistance to COX-2 inhibitionCRISPR knock out of COX-2 and 10 candidate genes in TNBC cells. a, b MDA-MB-231 cells were infected by lentivirus containing various gRNA sequences targeting 10 candidate genes (a) and COX-2 (b), and then subjected to Surveyor nuclease assay. Cleavage efficiency for each KO was calculated. c COX-2 KO in MDA-MB-231 cells was validated by western blotBack to article page
