About this study

Official title: Study of IGFBP-3 in the Ovarian Carcinoma Cell Invasion

An ovarian cancer cell line (OVTW-59) derived from an ovarian endometrioid carcinoma was established and its sublines, labeled as P0, P1, P2, P3, and P4 with increasing invasion abilities were selected from transwell invasion chambers.Using cDNA microarray and verified with quantitative reverse-transcriptase polymerase chain reaction, we have identified IGFBP-3 as an invasion-suppressor gene. We plan to study the role of IGFBP-3 in ovarian cancer invasion.

Read the detailed description

We have successfully established an ovarian cancer cell line (OVTW-59), which was derived from an ovarian endometrioid carcinoma. Its sublines, labeled as P0, P1, P2, P3, and P4 with increasing invasion abilities, were selected from transwell invasion chambers, where P0 represented the original cell line at 100th passage. By using cDNA microarray and verified with quantitative reverse-transcriptase polymerase chain reaction, we have identified the differentially gene expression profiles of these OVTW-59 series cell lines in order to identify the invasion related suppressor and oncogenes from ovarian carcinoma. From these genes, we selected insulin-like growth factor binding protein (IGFBP)-3, which is a suppressor gene, and found it lower expressed in higher-grade tumors and correlated with poor patient survival. In vitro, we found IGFBP-3 related to the inhibition of cancer cell migration. In this study, we plan to setup stable transfected IGFBP-3 cell lines in P0 and P4, and study the relationship among IGFBP-3, metalloproteinase-2 (our previous studies which verified its relationship with tumor invasiveness) and insulin-like growth factor (IGF)-1. We would study the changes in cytoskeletal structures and the known functions of anti-proliferation and apoptosis in IGFBP-3. Furthermore, we would like to investigate the mechanism of IGFBP-3 in the inhibition of invasion/migration of ovarian carcinoma, either signaling through MAPK or PI3K/AKT pathways. Finally, through xenograft, we plan to study for the possible application of IGFBP-3 in ovarian cancer therapy.

Questions about this trial

What is this clinical trial studying?

A study testing immunohistochemical staining, transfection, invasion assay in people with Ovarian Carcinoma, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 12 Sep 2005. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Torng Pao-Ling, MD, PhD (886223123456 ext. 7039, pltorng@ha.mc.ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

migration, invasion, metastasis. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2005.
