circRNA-disease information
Expression pattern:
UP
Associated gene: E2F1, eIF4A3
Associated microRNA: miR-1205
Biological function: promotes proliferation; promotes migration; promotes tumor growth; promotes liver metastasis; promotes EMT
Molecular mechanism: sponges miR-1205 to counteract miR-1205-mediated inhibition of E2F1; recruits eIF4A3 and stabilizes E2F1 mRNA; increases E2F1 to facilitate EMT
Biological pathway or process:

proliferation (promotes); migration (promotes); metastasis (promotes); EMT (promotes); ceRNA regulation (promotes); mRNA stability (promotes)

Detected method:
Q
M
Validation methods:

Microarray; Bioinformatics Analysis; RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Nuclear-Cytoplasmic Fractionation; FISH / smFISH; Sanger Sequencing; Back-Splice Junction PCR / divergent primers PCR; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Western Blot; RNA Pull-Down; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Wound Healing Assay; In Vivo Animal Model; H&E Staining; Co-IP

Clinical significance:

potential therapeutic target for patients with BCLM; prognosis correlation with circMYBL2 not verified

Description:

circMYBL2 (hsa_circ_0060467) is up-regulated in BCLM tissues and BC cells and promotes BC proliferation, migration, tumor growth, and liver metastasis. It sponges miR-1205 and recruits eIF4A3 to increase E2F1 (including via stabilizing E2F1 mRNA), thereby promoting EMT.

Confidence score:

0.8266
