Inhibition of miR-21 suppressed cell growth, migration and intracellular contents of lipids in human non-small cell lung cancer cells. a miR-21 inhibitor treatment inhibited miR-21 expression level. Cells were treated with miR-21 inhibitor or inhibitor control. The miR-21 expression level was detected. b miR-21 inhibitor suppressed cell growth. Cells were transfected with miR-21 inhibitor or inhibitor control. Cell number was counted after trypan blue staining. c The protein expression level of CD36 was detected. d Cellular content of phospholipids was detected in human non-small cell lung cancer cells. e Cellular content of triglycerides was detected in human non-small cell lung cancer cells. f miR-21 inhibitor suppressed cell migration. Cells were treated with miR-21 inhibitor or inhibitor control for 24 h or 48 h. migration abilities of cells were detected. *P < 0.05, **P < 0.01, ***P < 0.001
