Platinum resistance is a critical barrier for clinicians to improve the survival of ovarian cancer. Our study evaluated the correlation between copy number variations (CNVs) of neurotrophic tyrosine receptor kinase 3 (NTRK3) and the prognosis of ovarian cancer, which might predict platinum
Ovarian cancer is the number one cause of death from gynaecological malignancy. Platinum-based and taxol-based chemotherapy has been used as a standard therapy, but intrinsic and acquired resistance to chemotherapy is a major obstacle to treat the disease. In the present study, we found that in the
The vast majority of ovarian cancers originate in the ovarian surface epithelium. Unfortunately, there is a lack of appropriate animal models for ovarian cancer research. Spontaneously transformed mouse ovarian surface epithelial cells may provide a faithful animal model for human ovarian cancer.
Most women with epithelial ovarian cancer are diagnosed with advanced disease. Despite surgery and initial tumor reduction by standard chemotherapy, the tumors frequently recur and the patients eventually die of their disease. New drugs that inhibit tyrosine kinase receptors (TKRs) are being
Over-expression of EGFR, as in most cases of ovarian cancer, is associated with advanced-stage disease and poor prognosis. Activation of EGFR signaling pathway is involved in increased cell proliferation, angiogenesis, metastasis and decreased apoptosis. Tyrosine kinase activity is essential for
BACKGROUND
Epithelial ovarian cancer (EOC) is the second most common gynecologic malignancy and the leading cause of death from gynecologic cancer in the USA. EOC is an exquisitely chemo-sensitive disease with response rates of over 75% in the upfront setting. Despite this, due to high rates of
BACKGROUND
Epithelial ovarian cancer (EOC) is the leading cause of gynaecologic cancer death. Although in some cases initial treatment is effective, most of the women diagnosed with EOC will probably need medical treatment for their disease. There is a critical need to develop effective new
Increased expression and activation of human epidermal growth factor receptor (EGFR) and HER-2 have been reported in numerous cancers. The aim of this study was to determine the sensitivity of a large panel of human ovarian cancer cell lines (OCCLs) to treatment with various forms of small molecule
Src tyrosine kinase has been found to be overexpressed in both mouse and human ovarian cancer cells as well as in human primary ovarian cancers. Furthermore, Src inhibition sensitizes ovarian cancer cells to chemotherapeutic agents such as paclitaxel and cisplatin. Interestingly, Src inhibition has
Adaptive chemoresistance and consequent tumor recurrence present major obstacles to the improvement of the prognosis and quality-of-life of patients with advanced-stage ovarian cancer. In this issue of Cancer Cell, Yu and colleagues describe the critical role of spleen tyrosine kinase (SYK) in
Our current understanding of human ovarian tumorigenesis is limited by the lack of a discrete precursor lesion as well as a limited knowledge of the steps in tumor progression. Since the alterations in the regulation of the tyrosyl residues on various cellular proteins appear to be an important
The paper gives data on the changed levels of tyrosine-containing peptides (TCP) in the plasma of patients with ovarian tumors of varying histological structure. The most considerable blood TCP accumulations were observed in women with malignancies, which is indicative of their body's marked
For many decades, ovarian cancer (OC) has been one of the most common gynecological cancer. Despite advances in OC diagnosis and treatment, the risk of recurrence is ever present and approximately 85% of patients will experience relapse. Recurrent OC after first-line therapy is almost always
The Src protein tyrosine kinase is overexpressed and activated in a number of human cancers, including some human ovarian cancers. To determine whether Src activity plays a role in ovarian tumor growth, stable derivatives of the SKOv-3 human ovarian cancer cell line that exhibited reduced Src
BACKGROUND
Advanced ovarian cancer is often a fatal disease as chemotherapeutic drugs have limited effectiveness. Better targeted therapy is needed to improve the survival and quality of life for these women. Receptor tyrosine kinases including EGFR, Her-2 and c-Met are associated with a poor
