OVCAR8, a cell line derived from human ovarian adenocarcinoma, has been instrumental in advancing cancer research since its discovery in the early 1980s. Developed by J. C. Soucie and colleagues at the National Cancer Institute, OVCAR8 cells exhibit characteristics typical of high-grade serous ovarian carcinoma, making them valuable tools for studying ovarian cancer biology, progression, and therapeutic responses. OVCAR8 cells have been extensively characterized for their genetic and phenotypic features, including their ability to form tumors in xenograft models.
Moreover, the Luciferase Reporter Cell Line based on OVCAR8 provides an enhanced platform for studying gene expression regulation and signaling pathways implicated in ovarian cancer. This reporter system incorporates a luciferase reporter gene under the control of specific promoters or response elements, enabling quantitative assessment of transcriptional activity in OVCAR8 cells. The integration of luciferase technology with the OVCAR8 cell line enhances the sensitivity and specificity of detecting molecular events associated with ovarian cancer progression and treatment responses.
Proliferation And Apoptosis Adaptor (PEA15) is a 15kDa multifunctional phosphoprotein that plays crucial roles in regulating cancer cell proliferation and apoptosis. Researchers analyzed PEA15 expression in ovarian cancer tissues, finding it significantly upregulated compared to normal tissues. High PEA15 expression correlated with advanced cancer stages and poor prognosis. Knockdown inhibited cell proliferation and induced apoptosis, while overexpression promoted proliferation. miR-212 negatively regulated PEA15 expression and affected cell proliferation and apoptosis. PEA15 emerges as a promising biomarker and therapeutic target in ovarian cancer treatment.
Figure 1. Researchers analyzed miR212 regulation in ovarian cancer (OC) cells. They identified miR212 as a potential PEA15 target via luciferase reporter assays in OVCAR8 cells. MiR212 downregulation in OC tissues correlated with decreased PEA-15 expression. Overexpression of miR212 reduced PEA-15 protein levels, impacting cell proliferation and apoptosis.
