circRNA-disease information
Expression pattern:
UP
Associated gene: TCF12, PI3K, AKT, Ago2
Associated microRNA: miR-515-5p
Biological function: Promotes glioma cell proliferation, invasion, EMT and tumor growth; inhibits apoptosis.
Molecular mechanism: Acts as a ceRNA to sponge miR-515-5p, thereby upregulating TCF12 and activating the PI3K/AKT pathway.
Biological pathway or process:

PI3K/AKT (promotes); proliferation (promotes); invasion (promotes); EMT (promotes); apoptosis (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Clinical Sample Validation; Transfection; CCK8; BrdU; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; RIP (RNA Immunoprecipitation); RNA Pull-Down; Luciferase Reporter Assay; In Vivo Animal Model; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High circPIP5K1A expression is associated with shorter survival and malignant clinicopathological features; it is a potential prognostic marker in glioma.

Description:

CircPIP5K1A is up-regulated in glioma and promotes malignant behaviors (proliferation, invasion, EMT, tumor growth) while inhibiting apoptosis. Mechanistically, it sponges miR-515-5p to upregulate TCF12 and activate the PI3K/AKT pathway, and higher circPIP5K1A is associated with worse patient survival.

Confidence score:

0.8169

Title:

CircRNA PIP5K1A promotes the progression of glioma through upregulation of the TCF12/PI3K/AKT pathway by sponging miR-515-5p.
