Study Purpose

Research on the Role of Circ0014614 in the Formation and Development of ET

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Unknown
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years - 64 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. According to the classification and diagnostic criteria of hematological myeloid tumors by WHO 2016, patients diagnosed as ET are standardized. 2. Voluntary signing of informed consent form. 3. Age ≥ 18 years old, regardless of gender. 4. No pregnancy plan during treatment.

Exclusion Criteria:

1.The researcher judged that it was not suitable to participate in this study

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05921838
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

In recent years, tumor niche involved in the development of myeloproliferative disease（MPN）, which is remodelled by stem progenitor cells driving gene mutation, has attracted attention, but the reason and mechanism of remodelling microenvironment by mutated hematopoietic stem cells（ HSCs） are poorly understood. Our previous studies have shown that there is an obstacle in the transport of extracellular vesicles circ0014614 from MEPs in ET patients, which is enriched in the cytoplasm of megakaryocyte-erythroid progenitor（MEPs）, causing abnormal proliferation and reduced apoptosis of MEPs. The amplified MEPs affect the ossification of Mesenchymal stem cells（MCSs）. Based on this, we propose a hypothesis that circ0014614 may cause abnormal amplification of MEPs, reshape niche, induce ossification of MCSs, and abnormal amplification of osteoblasts（OBCs） through a certain pathway, promoting the formation and development of ET. This study will expand the collection of bone marrow samples from Essential thrombocytosis（ET） patients, detect the differences in circ0014614 levels in peripheral blood and bone marrow before and after treatment, and predict its downstream microRNA and mRNA through bioinformatics analysis to speculate its role in the occurrence and development of the disease.
