sub:_3 prov:value "In hyperplastic lung tissues and in tumors induced at early times after BRafVE expression, a high percentage of cells stain positive for Ki67 (Fig. 4E,F), phospho-histone H3, and BrdU incorporation. However, in tumors observed at later times, the percentage of Ki67-positive cells is dramatically decreased even though the BRafVE–MEK–ERK signaling pathway remains active in these cells (Figs. 3A,B, 4G)." ;
