| Research Abstract |
There is a lot of pathological evidence to suggest the theory that carcinoma of the ovary develops from endometrial tissue.Endometrial tissue expands with blood and then sheds the blood during menstruation. Red Blood Cells contain an iron-rich protein, hemoglobin. Iron overload is associated with carcinogenesis. In addition, the Fenton reaction may cause oxidative damage at a specific part of the genome. Hepatocyte nuclear factor-1beta (HNF-1beta), a transcription factor overexpressed in clear cell adenocarcinoma, might sustain chk1 protein phosphorylation to arrest the cell cycle and inhibit cell death induced by an anticancer agent. And, expression of CD44 is an important facter in endometriosis.
