IgG down-regulation inhibits lung cancer cell migration and attachment.

With specific IGHG1 siRNA transfection, the ability of migration and attachment of lung cancer cells was reduced markedly in A549 and SK-MES-1 cells, whereas not in Beas2B cells. A, representative photographs (200×) of transwell assays. B, representative photographs (200×) of attachment assays. The histograms represent the four independent assays. Data are presented as mean ± S.E. *, p<0.05.
