Polymorphism in codons 10 and 25 of the transforming growth factor‐beta 1 (TGF‐β1) gene in patients with invasive squamous cell carcinoma of the uterine cervix

Grazyna A. Stanczuk, S. A. Tswana, Staffan Bergström, Elopy Sibanda

Transforming growth factor-beta 1 (TGF-beta1) has a multifactorial role in the development of cervical cancer. It potently inhibits the growth of epithelial cells that harbour oncogenic human papilloma viruses (HPVs). TGF-beta1 also inhibits the expression of the early viral transforming regions E6 …
