MYC and lung adenocarcinoma: To establish that the ability of SLFN12 to reduce cell number in LUAD is at least in part through its effect in reducing c-myc protein levels, we analyzed cell numbers using toluidine blue cell staining after co-expression of both SLFN12 and c-myc using adenoviral vectors in H23 lung adenocarcinoma cells (we used H23 LUAD cells for this experiment because this cell line showed the least apoptotic cell death, as shown previously).
