Human placental alkaline phosphatase (HPLAP), carcinoembryonic antigen (CEA), and cancer antigen 125 (CA 125) were localized immunohistochemically in paraffin sections of normal lung tissue from 16 patients, using monoclonal antibodies and an indirect avidin-biotin-peroxidase staining procedure. HPLAP and CEA were present in epithelial cells of respiratory bronchioli and alveolar type I pneumoc...

CA 125 is found in body fluids in a variety of molecular weight forms. The largest species are found in normal abdominal fluid and cervical mucus. The present study therefore incorporated CA 125 derived from these sources as well as ascites fluid to investigate if the source of CA 125 influenced epitope characterization. Ascites-derived CA 125 varied in size from about 190 to about 2,700 kD. Ce...

Mucin16 [MUC16/cancer antigen 125 (CA-125)], a high-molecular-weight glycoprotein expressed on the ovarian tumor cell surface, potentiates metastasis via selective binding to mesothelin on peritoneal mesothelial cells. Shed MUC16/CA-125 is detectable in sera from ovarian cancer patients. We investigated the potential role of membrane type 1 matrix metalloproteinase (MT1-MMP, MMP-14), a transmem...

PURPOSE The capacity of nadir CA-125 levels to predict the prognosis of epithelial ovarian cancer remains controversial. This study aimed to explore whether the nadir CA-125 serum levels could predict the durations of overall survival (OS) and progression free survival (PFS) in patients with high-grade serous ovarian cancer (HG-SOC) from the USA and PRC. MATERIALS AND METHODS A total of 616 H...

The aim of this study was to assess the incidence of ovarian cancer in the industrial hub of Uttar Pradesh. A total of 50 samples were collected and estimated for CA-125 by Sandwich Method. CA-125 [Cancer antigen 125 or carbohydrate antigen 125 or Mucin 16] is a high molecular mass glycoprotein recognized by the monoclonal antibody OC 125 and encoded by MUC 16 gene. It contains 24% carbohydrate...

The aim of this study was to investigate the factors associated with serum levels of several tumor markers in a group of patients operated for uterine myoma. One hundred thirty-seven female patients operated for uterine myoma were included. Serum samples were examined for CA 125, CA 19-9, CA 15-3, carcinoembryonic antigen (CEA) and alpha-fetoprotein (AFP) levels as part of routine workup. Patho...

OBJECTIVE In the present study, we evaluated changes in CA-125 cut-off values predictive of complete interval debulking surgery (IDS) after neoadjuvant chemotherapy (NAC) using receiver operating characteristic (ROC) analysis. METHODS This retrospective single-institution study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage III epithelial ovarian can...

We developed a high-throughput yeast-based assay to screen for chemical inhibitors of Ca(2+)/calmodulin-dependent kinase pathways. After screening two small libraries, we identified the novel antagonist 125-C9, a substituted ethyleneamine. In vitro kinase assays confirmed that 125-C9 inhibited several calmodulin-dependent kinases (CaMKs) competitively with Ca(2+)/calmodulin (Ca(2+)/CaM). This s...
