circRNA-disease information
Expression pattern:
UP
Associated gene: PLAG1, ATG12
Associated microRNA: miR-488-3p
Biological function: promotes proliferation, migration, invasion and autophagy-associated cisplatin chemoresistance; promotes tumor growth in vivo
Molecular mechanism: ceRNA sponging of miR-488-3p leading to activation of PLAG1 and ATG12
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); autophagy (promotes); chemoresistance (promotes); ceRNA regulation (promotes)

Detected method:
Q
H
Validation methods:

RT-qPCR; ISH (In Situ Hybridization); FISH / smFISH; Nuclear-Cytoplasmic Fractionation; Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Colony Formation Assay; Transwell Assay; MTT; Annexin V/PI Flow Cytometry; IF (Immunofluorescence); Western Blot; ChIP / ChIP-seq; In Vivo Animal Model; IHC (Immunohistochemistry); Bioinformatics Analysis; Survival Analysis

Clinical significance:

increased circPOFUT1 expression indicated poor prognosis

Description:

circPOFUT1 is upregulated in gastric cancer and is associated with worse patient survival. It promotes proliferation, migration, invasion, and autophagy-associated cisplatin resistance by sponging miR-488-3p to activate the PLAG1-driven ATG12 program, enhancing tumor growth in xenografts.

Confidence score:

0.8772

Other information
Title:

Circular RNA circPOFUT1 enhances malignant phenotypes and autophagy-associated chemoresistance via sequestrating miR-488-3p to activate the PLAG1-ATG12 axis in gastric cancer.
