circRNA-disease information
Expression pattern:
DS
Associated gene: -
Associated microRNA: -
Biological function: circPVT1 is overexpressed in AML blast cells, enriched as cargo inside AML patient extracellular vesicles, and is suggested to participate in crosstalk between AML cells and the tumor microenvironment.
Molecular mechanism: extracellular vesicle cargo-mediated communication in the AML tumor microenvironment
Biological pathway or process:

immune regulation (other); other pathway/process (other)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Digital PCR

Clinical significance:

circPVT1 is more abundant inside EVs from the plasma of AML patients compared with healthy subjects and may reflect AML EV cargo features; the study suggests a potential role in AML cell-microenvironment crosstalk.

Description:

This study found circPVT1 overexpression in primary AML blast cells compared with normal CD34+ cells and enrichment of circPVT1 cargo inside plasma EVs from AML patients. The authors propose that EV-associated circPVT1 may participate in communication between leukemic blasts and the tumor microenvironment, although detailed functional mechanisms were not experimentally defined.

Confidence score:

0.3588
