Protein Biomarker For Ovarian Cancer

Background Epithelial ovarian cancer is characterised by an. It is a glycoprotein belonging to the family of whey acidic four-disulfide core proteins accounting for its alternative name of WFDC2 and the larger protein family called WAP for whey acidic proteins.

Ovarian cancer Platelet proteome Biomarker Liquid biopsy Background Epithelial ovarian cancer is characterised by an.

Protein biomarker for ovarian cancer. 03052021 Several studies have focused on proteomic alterations during carcinogenesis. The forest and the trees. In addition CA125 detected in the serumof early ovarian cancer.

Commonly used blood-based biomarker for ovarian cancer diagnostic. HE4 either gives higher specificity 95 and sensitivity 73 for ovarian cancer screening whereas in combination with CA125 sensitivity and specificity increase up to 100 and 74 respectively. 27032019 Human Epididymis Protein 4 HE4 is a new biomarker which has been currently evaluated for diagnosing ovarian malignant tumors.

06072021 Currently HE4 protein is still the most researched protein of WFDC family which is used for ovarian cancer biomarker in clinical trials. The goal of effective population-based screening for ovarian cancer remains elusive despite intense efforts aimed at improving upon biomarker and imaging modalities. 15012021 Protein biomarker HE4 is approved by FDA as a tumor marker for the onset progression and reoccurrence of epithelial ovarian cancer.

However CA125 is elevated in some case of certain common benign diseases such as endometriosis follicular cysts pregnancy and cystadenoma indicating that CA125 lacks the specificity to predict ovarian cancer 8. 01012012 Other protein biomarkers underexpressed in ovarian cancer include ApoA1 and transthyretin TTR which have been evaluated extensively as components of diagnostic panels for ovarian cancer and may originate from tumoral local or systemic sources 6268103104. 10042019 Novel biomarkers Over recent decades limitations in the ability of CA125 to detect ovarian cancer have led investigators to evaluate additional serum proteins as potential candidates for biomarker utility given the relative ease and reliable reproducibility of serum testing.

12012018 We identified a group of platelet protein biomarker candidates that can quantify the differential expression between ovarian cancer cases as compared to benign adnexal lesions. Protein biomarkers of ovarian cancer. Efficacy of other WFDC family proteins needs further researched by clinical trial.

04042018 TGF β1 MAGE 36 proteins have a cell-surface biomarker feature special for ovarian cancer. Plethora of proteins in different biological fluids may serve as prospective identifiers for the disease. We identified a group of platelet protein biomarker ca ndidates that can quantify the differential expression between ovarian cancer cases as compared to benign adnexal lesions.

20062019 MUCIN-16 also known as Cancer antigen 125 CA-125 was introduced as a biomarker for ovarian cancer in 1983 2 and is currently the most important single biomarker for epithelial ovarian cancer. The most valuable therapeutic targets to study the phenomenon of chemoresistance in advanced ovarian cancer are proteins. However higher levels of KLK4 expression are associated with the progression of ovarian cancer mainly late stage serous epithelial-derived ovarian carcinomas where hK4 represents a potential biomarker for diagnosis and.

Previous studies reported that KLK4 hK4 proteins are present in normal prostate tissue and are secreted in seminal plasma. These markers can be detected by filtration and ultracentrifugation methods in ovarian cancer plasma samples and can be used for prognosistherapy monitoring of disease. Over the years accurate identification of proteins secreted by EOC cells has been perfected by in vitro and in silico state of art technologies.

Kinase inhibitors PARP inhibitors and immune-checkpoint inhibitors. B7-h4 is a novel membrane-bound protein and a candidate serum and tissue biomarker for ovarian cancer. The diagnostic utility of these glycoprotein cancer biomarkers with the exception of prostate-specific antigen PSA is limited by lack of tissue specificity and they are used to monitor disease progression but are not adequate for screening.

Several initial studies in the early 2000s suggested combinations of. 01072003 We therefore performed experiments to explore whether quantitation of HE4 protein levels in serum can be used as a biomarker for ovarian carcinoma. A fusion gene was constructed encoding the HE4 protein fused to a gene encoding the murine IgG2a Fc domain.
