Beschreibung:

Background: Breast cancer is a malignant tumor arising from the terminal duct lobular unit of the breast tissues. It is most prevalent malignancy in women and its incidence is increasing, approximately equals to 5-10%.Forkhead box M1 (FOXM1) is a transcription factor associates with proliferation signals and over-expressed in majority of human cancer involved breast. TP53 gene negatively regulates FOXM1 expression and therefore inactivation of TP53 in tumors could partially illustrate the phenomenon of FOXM1 over-expression in human cancers. Objectives: The main objective of the current study is to analyze FOXM1 and TP53 gene expressions levels in formalin fixed paraffin embedded tissues of breast cancer specimens.Subjects and Methods: One hundred formalin fixed paraffin embedded (FFPE) tissue samples of malignant breast tumors as well as 100 FFPE samples of normal breast tissues were investigated. Ages of patients (Mean ±SD) were 48.4 ± 10.90 year with a minimum to maximum of 20 -75 years. Total mRNA was extracted from FFPE blocks by using a specific kit.FOXM1 and TP53 gene expressions were estimated quantitatively by real time PCR.
