Expression of ras Oncogene Product, MHC class II Antigen and Human Papillomavirus 16/18 DNA in Carcinomas of the Uterine Cervix.: K J Cho, Ja June Jang; Korean J Pathol. 1993;27(5):485-490.

Abstract PDF: Immunohistochemical study for ras oncogene product(p21) and MHC class II(HLA-DR) antigen, and in situ hybridization for human papillomavirus(HPV) type 16/18 were performed on 50 squamous cell carcinomas of the uterine cervix. Activated ras and aberrant DR expression were noted in 26 cases(52%) and 11 cases(22%), respectively, without a difference between keratinizing and non-keratinizing types. No direct correlation between ras and DR expression was histologically found. p21 was diffusely distributed with a finely granular pattern in the cytoplasm. Aberrant DR expression was also diffuse, with linear staining along the cell membrane. In situ hybridization revealed HPV type 16/18 DNAs in superficial koilocytotic cells of 4 cases, in which ras or DR expression was not correlated with the presence of HPV DNA.
