Abstract:
ObjectiveTo examine the expressions of amplified in breast cancer 1(AIB1) and epithelial cadherin (E-cadherin) in ovarian carcinoma (OC) tissues,and determine the correlation between the expression and clinical pathological features.MethodsThe expression of AIB 1,E-cadherin,estrogen receptor (ER),progesterone receptor (PR) and Ki-67 in tissues of 50OCs and 13 normal ovarians tissues were detected by immunohistochemistry(IHC) EnVision two step process analysis.ResultsPositive expression of AIB1 in OC tissues[68%(34/50) ] was obviously higher than that in normal ovarian tissues [8% (1/13)] (P <0.01).Down-regulation of E-cadherin expression was 60% (30/50).The positive expression of AIB1 was significantly higher in stage Ⅲ and Ⅳ than in stage Ⅰand Ⅱ according to International Federation of Gynecology and Obstetrics (FIGO) stage (P =0.036),in lymph node metastasis group than in none lymph node metastasis group ( P =0.027 ),in stage G3 than in stage G1 and G2 according to Silverberg stage (P =0.003),and in serous adenocarcinoma group than in non-serous adenocarcinoma group (P=0.049);positive rates of ER and Ki-67 were higher than negative rates of ER(P=0.000) and Ki-67 (P =0.009) respectively.Down-regulation of E-cadherin expression was higher in FIGO stage Ⅲ and Ⅳ than in stage Ⅰ and Ⅱ (P =0.044),in serous adenocarcinoma group than in non- serous adenocarcinoma group ( P =0.022) ; positive rates of ER and Ki-67 were higher than negative rates of ER ( P =0.02 1 ) and Ki-67 (P=0.035) respectively.The expression of AIB1 was negatively correlated with E-cadherin expressioh (P =0.026).ConclusionsThe expressions of AIB1 and E-cadherin in OC tissues is closely related to clinical stage.Therefore,AIB1 and E-cadherin may be important moleculars involved in the progression of OC.
