Abstract:
ObjectiveTo explore the expression of p130Cas and paxillin in breast carcinoma and investigate the relationships of p130Cas and paxillin levels with clinical and pathological characteristics.MethodsReverse transcriptase polymerase chain reaction (RT-PCR) was applied to detect the expression of p130Cas and paxillin in tumor tissues from 30 cases of primary breast carcinoma,15 cases of normal breast tissues and 10 cases of breast fibroadenoma.ResultsThe levels of p130Cas and paxillin were 0.444 ± 0.088,0.493 ± 0.073,0.739 ± 0.092,0.755 ± 0.137 in normal breast tissues and breast fibroadenoma tissues.The levels of p130Cas and paxillin were 0.914 ±0.186,0.303 ±0.043 in breast carcinoma tissues.Breast carcinoma tissues showed higher levels of p130Cas and lower levels of paxillin than normal breast tissues and breast fibroadenoma tissues(P ＜ 0.01 ).The expression of p130Cas was related with age (r =0.599,P =0.000 ),menopausal status (t =5.602,P =0.000 ),estrogen receptor ( ER ),progesterone receptor ( PR ) status (t =5.768,P =0.000; t =4.151,P =0.000 ) and histological grades (r =-0.668,P =0.000 ),but not related with tumor size (F =0.717,P =0.497 ),lymph node status (F =1.230,P =0.308 ) and pathological stages(r =0.283,P =0.137).The expression of paxillin was related with rumor size (F=4.114,P =0.028 ),pathological stages( r =-0.520,P =0.003),and lymph node status(F=12.418,P=0.000 ),but not related with age(r =0.294,P=0.115),menopausal status(t =-0.403,P =0.690),ER,PR status(t =0.749,P =0.460;t =0.006,P =0.995) and histological grades (r =-0.173,P =0.362).Conclusions p130Cas and paxillin have relations with the malignant transformation,invasion and metastasis of breast carcinoma.Measurement of p130Cas and paxillin may provide useful prognostic information for patients with primary or metastatic breast carcinoma.
