The human cervical carcinoma cell line HeLa and human embryonic kidney cell line HEK293A were obtained from ATCC (Manassas, VA, USA). LATS1/2-DKO HEK293A cells were generously provided by Dr Kun-Liang Guan, the Department of Pharmacology and Moores Cancer Center at University of California San Diego (43 (link)). The cells were maintained in Dulbecco's modified Eagle medium (DMEM; WELGENE, Gyeongsan, Korea) supplemented with 10% fetal bovine serum (FBS; Gibco, Gaithersburg, MD, USA), 100 U/ml penicillin, and 100 μg/ml streptomycin (WELGENE). The cells were incubated at 37°C in a humidified atmosphere containing 5% CO2.
