circRNA-disease information
Expression pattern:
UP
Associated gene: PKP3
Associated microRNA: miR-328-5p
Biological function: Promotes NSCLC tumor progression, cellular proliferation, migration, invasion, dissemination, and tumorigenesis in vitro.
Molecular mechanism: circFOXK2 functions as a ceRNA and molecular sponge for miR-328-5p, thereby upregulating PKP3 expression.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Wound Healing Assay

Clinical significance:

The circFOXK2/miR-328-5p/PKP3 signaling axis is identified as a potential therapeutic target in NSCLC.

Description:

circFOXK2 is up-regulated in NSCLC tissues and cell lines. It promotes NSCLC cell proliferation, migration, invasion, and tumorigenic progression in vitro by sponging miR-328-5p and indirectly increasing PKP3 expression. The circFOXK2/miR-328-5p/PKP3 axis is proposed as a potential therapeutic target for NSCLC.

Confidence score:

0.6521
