Small interfering RNA (siRNA)‐mediated suppression of α5 integrin. (a) α5 integrin mRNA expression levels in Lewis lung cancer (LLC)/control and LLC/α5 siRNA were determined with quantitative real‐time polymerase chain reaction using specific primer sets. The result is expressed as mean ± SD. P < 0.05 versus LLC/control. (b) The expression of α5 integrin in LLC/control and LLC/α5 siRNA were assessed with flow cytometric analysis. The dotted lines indicate the fluorescence intensity of α5 integrin.
