circRNA-disease information
Expression pattern:
UN
Associated gene: EML4-ALK1, SMAD4, ADAR1
Associated microRNA: miR-4673
Biological function: F-circEA1 promotes proliferation, migration, invasion and xenograft tumor growth of EML4-ALK1-positive LUAD cells; interference with F-circEA1 inhibits xenograft growth and EML4-ALK1 expression.
Molecular mechanism: F-circEA1 sponges miR-4673 and participates in a feedback pathway involving SMAD4 and ADAR1 to regulate EML4-ALK1 expression; ADAR1 binds F-circEA1 and facilitates its expression.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); ceRNA regulation (other); TGF-beta/SMAD (other)

Detected method:
Q
H
Validation methods:

RT-qPCR; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Transwell Assay; Western Blot; IHC (Immunohistochemistry); ChIP / ChIP-seq; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

F-circEA1/miR-4673/SMAD4/ADAR1 pathway may provide therapeutic ideas and possible therapeutic direction for EML4-ALK1-positive LUAD.

Description:

F-circEA1 is a human fusion circRNA associated with EML4-ALK1-positive lung adenocarcinoma. It promotes malignant phenotypes of LUAD cells by sponging miR-4673 and participating in a feedback network involving SMAD4, ADAR1 and EML4-ALK1; F-circEA1 interference suppresses xenograft growth and EML4-ALK1 expression.

Confidence score:

0.7629
