circRNA-disease information
Expression pattern:
UP
Associated gene: TRIM31
Associated microRNA: miR-876-3p
Biological function: circNFIX promotes AML cell proliferation and cell cycle progression and inhibits apoptosis; circNFIX knockdown suppresses proliferation, induces G0/G1 cell cycle arrest, and promotes apoptosis in AML cells.
Molecular mechanism: circNFIX acts as a miR-876-3p sponge and indirectly up-regulates TRIM31 expression through miR-876-3p, thereby promoting AML cell malignant progression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; ROC Analysis; Transfection; MTT; EdU Staining; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Western Blot; Luciferase Reporter Assay; RNA Pull-Down; Bioinformatics Analysis

Clinical significance:

circNFIX may have diagnostic value for AML, with serum circNFIX ROC AUC of 0.927, sensitivity of 83%, and specificity of 97.5%; circNFIX may be an effective target for future AML therapy.

Description:

circNFIX is up-regulated in AML bone marrow samples and AML cell lines and may serve as a diagnostic biomarker. Functionally, circNFIX promotes AML cell proliferation and cell cycle progression while suppressing apoptosis. Mechanistically, circNFIX sponges miR-876-3p to up-regulate TRIM31 expression, forming a circNFIX/miR-876-3p/TRIM31 axis that supports AML progression.

Confidence score:

0.7548
