About this study

This study involves observing the level of cell cycle regulatory gene in patients with myeloproliferative disorders(MPD). These disorders include polycythemia vera (PV), essential thrombocythemia (ET), myelofibrosis (MF) and chronic myeloid leukemia (CML). The abnormal blood and/or bone marrow cells, or materials derived from these abnormal cells, like DNA, RNA, protein or plasma will be used in laboratory studies.

Cell cycle regulatory protein such as cyclins, cyclin-dependent kinases(Cdks) and Cdk inhibitors(CKIs) play indispensable roles in processes such as transcription, metabolism and stem cell self-renewal. MPD are a group of diseases characterized by abnormally increased proliferation of erythroid, megakaryocytic, or granulocytic cells. The pathogenesis was still unclear. Detecting the level of cell cycle regulatory protein will be useful to look for the possible role in MPD and better understand the cause of MPD.

In this study, the cell cycle regulatory message RNA and protein from patients' and healthy volunteers' bone marrow and peripheral blood will be extracted and quantified by real time polymerase chain reaction and western blot. The different level of cell cycle regulatory gene between patients and volunteers and the relationship between the level and patients' clinical characteristics such as age, gender, type of disease will be analysed by SPSS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. quantified the level of CDK, CCP, PLK by real time PCR and westen blot

    The cell cycle regulatory message RNA and protein from patients' and healthy volunteers' bone marrow and peripheral blood will be extracted and quantified by real time polymerase chain reaction and western blot. The cell cycle regulatory genes contain CDK ,CDKI, Ser/Thr protein kinase, ATP/GTP binding protein-like and so on.

    Measured: two years

  2. age of MPN patients and volunteers

    observe the age of MPN patients and volunteers, and analyze the correlation between the level and the age of patients.

    Measured: two years

  3. gender of MPN patients and volunteers

    observe different level of cell cycle regulatory gene between male patients and femal patients.

    Measured: two years

  4. count of peripheral blood cells

    observe the count of peripheral blood cells, including the white blood cell, red blood cell and platelet.

    Measured: two years

Questions about this trial

What is this clinical trial studying?

An observational study of Myeloproliferative Disorders and Polycythemia Vera, run by Shandong University at 1 site in China.

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: withdrawn, as of the sponsor's last update on 20 Apr 2016. 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 China. 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?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

quantified the level of CDK, CCP, PLK by real time PCR and westen blot (time frame: two years). The study lists 4 primary outcomes in all. 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 20 Apr 2016.
