circRNA-disease information
Expression pattern:
DN
Associated gene: DDX5 / DEAD-box helicase 5 / Ago2
Associated microRNA: miR-340-5p
Biological function: Mitigates cerebral ischemia-reperfusion/OGD/R-induced neuronal injury by inhibiting apoptosis and inflammation and reducing LDH release; knockdown aggravates injury and promotes glial activation.
Molecular mechanism: Acts as a competing endogenous RNA (ceRNA) that sponges miR-340-5p to regulate DDX5, thereby modulating NF-kappaB activation and neuronal injury phenotypes.
Biological pathway or process:

apoptosis (inhibits); inflammation (inhibits); NF-kappaB (inhibits); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; Bioinformatics Analysis; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; CCK8; Annexin V/PI Flow Cytometry; ELISA; Western Blot; TUNEL; IF (Immunofluorescence); In Vivo Animal Model; H&E Staining

Clinical significance:

-

Description:

circPUM1 is down-regulated in tMCAO mouse brain and OGD/R-treated SH-SY5Y cells. Functionally, circPUM1 overexpression alleviates neuronal injury (reduced apoptosis, inflammation, LDH release) by sponging miR-340-5p to increase DDX5 and suppress NF-kappaB pathway activation.

Confidence score:

0.6279
