circRNA-disease information
Expression pattern:
UP
Associated gene: PI3K/Akt/mTOR signaling
Associated microRNA: miR-613, miR-206
Biological function: facilitates chemo-tolerance/chemo-resistance and promotes proliferation, migration and invasion; modulates autophagy; reduces chemosensitivity in TNBC cells
Molecular mechanism: ceRNA sponging of miR-613 and miR-206 leading to activation of PI3K/Akt/mTOR signaling
Biological pathway or process:

PI3K/AKT/mTOR (promotes); proliferation (promotes); migration (promotes); invasion (promotes); autophagy (other); ceRNA regulation (promotes); chemoresistance (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Survival Analysis; Luciferase Reporter Assay; Transfection; MTT; CCK8; Transwell Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

high hsa_circ_0000199 expression was predictive of large tumor size, advanced TNM grade, high Ki-67 level and poor 3-year survival of TNBC patients

Description:

hsa_circ_0000199 (AKT3-derived) is up-regulated in TNBC and promotes malignant phenotypes and chemoresistance. It sponges miR-206 and miR-613 to modulate PI3K/AKT/mTOR signaling, affecting proliferation, migration/invasion, chemosensitivity and autophagy, and its high expression predicts poor survival in TNBC patients.

Confidence score:

0.7126
