circRNA-disease information
Expression pattern:
UP
Associated gene: GRB10
Associated microRNA: miR-5195-3p
Biological function: circ_0009910 promotes AML cell proliferation and cell cycle progression and inhibits apoptosis; knockdown suppresses proliferation and cell cycle progression while facilitating apoptosis.
Molecular mechanism: Exosome-transmitted circ_0009910 acts as a ceRNA sponge for miR-5195-3p to modulate GRB10 expression, thereby regulating AML cell proliferation, cell cycle and apoptosis.
Biological pathway or process:

proliferation (promotes); cell cycle (promotes); apoptosis (inhibits); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Western Blot; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Bioinformatics Analysis

Clinical significance:

High circ_0009910 expression was significantly correlated with AML risk status and was associated with poor risk status; it may have potential diagnostic and prognostic value in myeloid leukemia.

Description:

In AML, hsa_circ_0009910/circ_0009910 is up-regulated in bone marrow samples, AML cell lines, and AML cell-derived exosomes. It functions as an oncogenic exosomal circRNA that promotes proliferation and cell cycle progression while inhibiting apoptosis, at least partly through the circ_0009910/miR-5195-3p/GRB10 ceRNA axis. Clinically, higher circ_0009910 expression is associated with AML risk status and poor-risk disease.

Confidence score:

0.7032
