circRNA-disease information
Expression pattern:
UP
Associated gene: ZNF90
Associated microRNA: miR-6809-3p
Biological function: promotes proliferation and migration/invasion; suppresses apoptosis; facilitates in vivo tumor growth; promotes EMT
Molecular mechanism: ceRNA mechanism: circMRPL35 sponges miR-6809-3p to de-repress ZNF90, affecting EMT and TGF-beta1/SMAD2/3 signaling
Biological pathway or process:

EMT (promotes); TGF-beta/SMAD (promotes); proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; Bioinformatics Analysis; RT-qPCR; RNase R Treatment; divergent primers PCR; Sanger Sequencing; FISH / smFISH; Clinical Sample Validation; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Wound Healing Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Western Blot; IF (Immunofluorescence); Luciferase Reporter Assay; In Vivo Animal Model; ELISA

Clinical significance:

correlating with lymphatic metastasis and tumor size; potential biomarker for GC

Description:

circMRPL35 is upregulated in gastric cancer tissues and cell lines and promotes GC cell proliferation, migration/invasion, EMT, and in vivo tumor growth while inhibiting apoptosis. Mechanistically, it acts as a ceRNA that sponges miR-6809-3p to increase ZNF90, thereby activating the TGF-beta1/SMAD2/3 signaling axis.

Confidence score:

0.8072

Other information
Title:

circMRPL35 promotes gastric cancer progression through the miR-6809-3p/ZNF90 axis and affects the EMT process and TGF-beta1/SMAD2/3 signaling.
