TRIM24 and lung cancer: Our cell proliferation analysis showed that the depletion of TRIM24 in H1299 and A549 cells led to a significant reduction of the proliferation rate (A549 39% reduction at day 5, p<0.05; H1299 23% reduction at day 5, p<0.05) and foci numbers as well as sizes (A549 control vs TRIM24si: 400±38 vs 130±20, p<0.05; H1299 control vs TRIM24si: 235±25 vs 85±18, p<0.05), suggesting that TRIM24 modulates proliferation of lung cancer cells (Figure 4).
