DNA and nuclear protein characteristics in non-neoplastic and neoplastic endometrial tissue.
Feulgen-DNA and nuclear protein (NP) measurements were performed on non-neoplastic and neoplastic endometrium. Non-neoplastic endometrial cells were exclusively characterized by euploid nuclear DNA content. The NP content may vary significantly in relation to the proliferative stage as reflected by a 2-3-fold increase NP/DNA ratio in growing as compared to growth arrested cells. Endometrial adenocarcinomas could be subdivided into euploid and aneuploid types. The euploid tumors were found to exhibit DNA and NP characteristics comparable with those of normal tissue. In contrast, aneuploid tumors showed DNA and NP characteristics indicating increased proliferative activity as well as a pronounced disorder between the DNA and protein cycle.
