We found the gradual decreased expression of Notch-1 (80kDa) and increased expression of Notch-3 (244 kDa) in precancer (P1, P2) and squamous cell cervical carcinoma (C1, C2) as compared to the normal tissues (N1, N2; Figure-1N). This evidence concerns the gene NOTCH3 and cervical squamous cell carcinoma.
