As shown in Figure 2C, the transfected cells had much higher viability or proliferative capacity than SKOV3; meanwhile, they also displayed increased colony formation capacity (Figure 2D); furthermore, according to the cell cycling assay, SKOV3-IGF-1R cells (pool) has S-phase cells than SKOV3, suggesting much quicker cell multiplication rate of SKOV3-IGF-1Rcells (Figure 2E); in in vivo tumor formation assay, IGF-1R positive cells exhibited more rapid growth capacity than parental cells (Figure 2F), indicating thatIGF-1R can promote the proliferation of SKOV3. The gene discussed is IGF1R; the disease is neoplasm.
