circRNA-disease information
Expression pattern:
DN
Associated gene: PIF1, AGO2, AIM2, ASC, BRCA1, gammaH2AX, caspase-1, GSDMD, GSDMD-N, IL-1beta, IL-18
Associated microRNA: miR-1184
Biological function: circNEIL3 knockdown promotes radiation-induced cell pyroptosis and enhances radiotherapy efficacy; circNEIL3 overexpression inhibits pyroptosis in irradiated LUAD cells.
Molecular mechanism: Acts as a ceRNA/miRNA sponge for miR-1184 to relieve repression of PIF1, leading to increased DNA damage and AIM2 inflammasome activation, thereby affecting pyroptosis during radiotherapy.
Biological pathway or process:

pyroptosis (inhibits); other pathway/process (other); ceRNA regulation (other)

Detected method:
Q
S
Validation methods:

circRNA-seq; RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Nuclear-Cytoplasmic Fractionation; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; Transfection; ELISA; Annexin V/PI Flow Cytometry; Western Blot; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; IF (Immunofluorescence); In Vivo Animal Model; IHC (Immunohistochemistry); Colony Formation Assay; Bioinformatics Analysis

Clinical significance:

Potential therapeutic target/strategy to enhance radiotherapy in lung cancer.

Description:

In irradiated LUAD cells, circNEIL3 is downregulated and functions as a cytoplasmic ceRNA by sponging miR-1184 to upregulate PIF1. This axis modulates DNA damage/AIM2 inflammasome signaling to regulate radiation-induced pyroptosis and affects radiotherapy efficacy in vivo.

Confidence score:

0.8366
