DTL and cervical cancer: To check that if this effect is getting translated at protein level, we performed western blot analysis for HPV positive and negative cervical cancer cells to be confirmed that there is a significant amount of decrease in the levels of Cdt2 protein in cancerous cells (Fig. 2B, Lanes 3–8 and Fig. 2C), while no such effect could be observed in non-cancerous cells (Fig. 2B, Lanes 1 and 2 and Fig. 2C).
