Background: Understanding of cellular and molecular mechanisms involved in cell/tumor growth and progression has led to molecular-targeted therapy. HER1 and HER2 are two main oncogenic components of HER-receptor family considered as targets for cancer research and therapy. Reliable results of HER- related research and targeted therapies dependent upon cell line with known HER expression status....
Background Circulating tumor cells (CTCs) can provide the basis for a liquid biopsy and may guide the use of targeted therapies. We report on unbiased quantification of Her-2 protein expression of CTCs. Patients and methods Her-2 assessment of CTCs was carried out using the CellSearch(®) system in 103 metastatic (M1) and 88 non-metastatic (M0) breast-cancer patients. Expression of Her-2 on CTCs...

In an insightful essay on the representation of racial and religious difference in early modern English drama, Ania Loomba has pointed out the crucial significance of gender in this respect. More often than not, she observes, ‘a fair maid of an alien faith and ethnicity [is] romanced by a European, married to him, and converted to Christianity. Her story, unlike those of converted men, does not...
پروتئین کیناز atm نقش مهمی در حفظ تمامیت ژنوم از طریق فعال کردن زنجیره واکنش های بیوشیمیایی که به فعال کردن نقاط کنترلی چرخه سلولی و ترمیم اسیب dna می انجامد، ایفا می کند. سایکلین d1 در تنظیم مرحله g1 چرخه سلولی نقش دارد. مطالعات تجربی و بالینی دخالت آنها را در ترنسفورماسیون و توسعه تومور پیشنهاد می کند. توجهات زیاد به دقت روش های سنجش her-2 مبین اهمیت روزافزون وضعیت her-2 در مدیریت بیماران مبت...
Amplification and overexpression of the HER-2 (neu/ erbB-2) gene in human breast cancer are clearly important events that lead to the transformation of mammary epithelial cells in approximately one-third of breast cancer patients. Heterodimer interactions between HER-2 and HER-3 (erbB-3) are activated by neu differentiation factor/heregulin (HRG), and HER-2/HER-3 heterodimers are constitutively...
AIMS Topoisomerase IIalpha (TOPOIIalpha) and HER-2/neu are chromosome 17q genes coamplified in various cancers; no data exist for Barrett's oesophagus (BO) and BO adenocarcinoma (ADC). The aim was to investigate gene amplification and protein overexpression of TopoIIalpha and Her-2/neu in non-dysplastic BO, dysplastic BO, Barrett ADC, and chromosome 17 aneusomy. METHODS AND RESULTS Forty-four...
Analysis of HER-2/neu gene amplification by fluorescence in situ hybridization was performed in 40 patients with invasive bladder cancer in order to evaluate the potential for molecular targeted therapy of HER-2 as a tailor-made treatment for patients with invasive bladder cancer. This study included 40 patients seen at the Aichi Medical University Hospital from January 2001 to December 2004 an...
