circRNA-disease information
Expression pattern:
UP
Associated gene: MTDH
Associated microRNA: miR-124-3p
Biological function: Promotes endothelial cell viability, tube formation, angiogenesis, and tumor growth in breast cancer context.
Molecular mechanism: Exosomal circHIPK3 acts as a ceRNA that sponges miR-124-3p, thereby increasing MTDH expression and promoting angiogenesis.
Biological pathway or process:

angiogenesis (promotes); proliferation (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RT-qPCR; FISH / smFISH; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Tube Formation Assay; Western Blot; IHC (Immunohistochemistry); H&E Staining; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

Might serve as a therapeutic target for anti-angiogenesis therapy for breast cancer.

Description:

In this study, breast cancer cell-derived exosomal circHIPK3 was upregulated and could be transferred to endothelial cells. It promoted endothelial cell proliferation, tube formation, angiogenesis, and tumor growth by sponging miR-124-3p and increasing MTDH expression, suggesting potential value as an anti-angiogenesis therapeutic target in breast cancer.

Confidence score:

0.7799

Other information
Title:
