The aim of the multicenter study is to investigate the correlation between the expression of estrogen alpha receptors (ERα), progesterone receptors (PR), human epidermal growth factor receptor 2 (HER2), stromal cell-derived factor 1 (SDF1) and its receptor C-X-C chemokine receptor type 4 (CXCR4), breast cancer metastasis suppressor 1 (BRMS1), astrocyte elevated gene 1 (AEG1), depending on the status of BRCA1 protein, in patients suffering from OC and BC with brain metastases.
In conclusion, HER2 protein is over-expressed in epithelial ovarian cancer tissues, and trastuzumab exerts anti-tumor effect by inhibiting cell proliferation and inducing apoptosis, suggesting it might be a novel approach for the treatment of ovarian cancer.
In order to assess the validity of ErbB2-targeted therapy in ovarian cancer, we investigated the effectiveness of two FDA-approved tyrosine kinase inhibitors of ErbB2, lapatinib and neratinib, on the growth of ovarian cancers.
In the present work we combined functional and spectroscopic magnetic resonance technologies, such as in vivo diffusion-weighted MRI and <sup>1</sup> H MRS, with ex vivo high resolution MRS (HR-MRS) metabolomic analyses, with the aim of identifying new pharmacodynamic markers of Trab effectiveness on well characterized, highly aggressive human SKOV3.ip (a HER2-enriched cell variant derived from SKOV3 cells) EOC xenografts.
However, analyses that considered all 41 genes with clinical variables together identified genes TLR4, BSCL2, CDH1, ERBB2, BRCA2 and SCGB2A1 as independently related to survival in OC.
The prognostic role of human epidermal growth factor receptor 2 (HER2) in ovarian cancer has been investigated in previous studies, but the results remain controversial.
The data demonstrate that the growth of xenografts of human ovarian cancer with high expression of HER2 could be inhibited effectively by Ad-HER2-siRNA+DDP.
PET imaging and biodistribution studies in subcutaneous models of ovarian cancer were performed for non-invasive in vivo evaluation of HER2 expression.
Our study showed that the expressions of HER2, STAT3, and SOCS3 are associated with the progression of OC, and higher expressions of HER2 and STAT3 and lower expression of SOCS3 predict poor prognosis of OC.
Goals of this study were: i) to define a possible association between Estrogen Receptor (ER), Progesterone Receptor (PR), Androgen Receptor (AR),human EGF receptor 2 (HER2) and brain progression in EOC patients, and ii) to identify differences in ER, PR, AR and HER2 protein expression from primary EOC and its matched resected brain metastasis.
SYD985 and T-DM1 induced similar ADCC in the presence of peripheral blood lymphocytes (PBL) against EOC cell lines with differential HER2/neu expression.
Overall, these findings support the view that PC-PLC inhibition may represent an effective means to target the tumorigenic effects of HER2 overexpression in EOC and that <i>in vivo</i> MR approaches can efficiently monitor its effects.
