Figure 3From: Klotho inhibits growth and promotes apoptosis in human lung cancer cell line A549Effects of klotho on A549 cells growth dynamics determined by MTT. (A) A549 cells transfected by negative control-shRNA (shRNAc) or klotho-directed shRNAs sh-2 and sh-4. (B) A549 cells were transfected with either MYC-KL or pCMV6, starved for 24 hr and treated by IGF-1 (25 nM) for 24-96 hr.Back to article page
