small cell nueroendocrine ca
which one - beshi - in cervical carcinoma ?

E6
E7
Carcinoma in situ feature ?
severe dysplasia
diffuse atypia
progressive atypia
E6 pathogenesis ?
E6 = binds with p53 = degrade it = upregulate the expression of telomerase = leads to cellular immortalization
E7 pathogenesis ?
E7 binds with hypophosphorylated active form of RB & promote the degradation via proteosome pathway —- inhibit p21 p27 = cyclin dependent kinase inhibitors

exo/ecto-cervix lining ?
squamous epithelium
