Figure 2. S100A4 controls metastatic activity.
(A) LM2 cells were infected with lentiviruses encoding the indicated shRNAs. Equal amounts of total proteins were subjected to immunoblotting with antibodies to the indicated antigens. shSC, non-targeting shRNA; shS100A4, shRNAs targeting S100A4. (B) SN12C cells were infected with retroviruses bearing a vector encoding S100A4 or an empty vector. Total cellular lysis was subjected to immunoblotting using antibodies against the specified proteins. (A, B graphs) Groups of 5 mice were injected in the kidney subcapsule with the indicated cell populations and numbers of lung metastatic nodules were scored after 2 months.
