circRNA-disease information
Expression pattern:
DN
Associated gene: AKT/mTOR pathway
Associated microRNA: miR-19a-3p
Biological function: Tumor-suppressive in cervical cancer: increased circHIAT1 contributes to inhibition of cell growth and cell cycle progression and promotion of apoptosis; required for baicalein-mediated suppression of CC and tumor growth in vivo.
Molecular mechanism: circHIAT1 acts as a miRNA sponge (ceRNA-like) for miR-19a-3p, contributing to AKT/mTOR pathway inactivation in baicalein-treated cervical cancer cells.
Biological pathway or process:

PI3K/AKT/mTOR (inhibits); apoptosis (promotes); cell cycle (inhibits); proliferation (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; Luciferase Reporter Assay; RNA Pull-Down; Transfection; CCK8; Colony Formation Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Western Blot; Clinical Sample Validation; Bioinformatics Analysis; In Vivo Animal Model

Clinical significance:

CircHIAT1 is downregulated in CC tissues and is suggested as an available target in baicalein-mediated treatment of CC.

Description:

circHIAT1 is downregulated in cervical cancer tissues/cells but is induced by baicalein. It suppresses CC malignant behaviors by sponging miR-19a-3p and contributing to AKT/mTOR pathway inactivation, thereby inhibiting proliferation/cell cycle progression and promoting apoptosis, including reduced xenograft tumor growth.

Confidence score:

0.705
