circRNA-disease information
Expression pattern:
UP
Associated gene: ZEB1
Associated microRNA: miR-1236-3p
Biological function: promotes LUAD cell metastasis and induces EMT
Molecular mechanism: acts as a miRNA sponge for miR-1236-3p to relieve repression of ZEB1, thereby promoting EMT and metastasis
Biological pathway or process:

EMT (promotes); metastasis (promotes); migration (promotes); invasion (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RNase R Treatment; Sanger Sequencing; Actinomycin D / DRB Stability Assay; RT-qPCR; Clinical Sample Validation; Transfection; Transwell Assay; Wound Healing Assay; Luciferase Reporter Assay; FISH / smFISH; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model; H&E Staining; Bioinformatics Analysis; Back-Splice Junction PCR / divergent primers PCR

Clinical significance:

may have important significance in the diagnosis of LUAD and may become biomarkers of LUAD in the future

Description:

circ-HMGA2 (hsa_circ_0027446) is up-regulated in LUAD tissues and cells and promotes migration/invasion and lung metastasis by inducing EMT. It mainly localizes to the cytoplasm and functions as a ceRNA by sponging miR-1236-3p to increase ZEB1 expression, thereby activating an EMT program.

Confidence score:

0.8455

Other information
Title:

Circ-HMGA2 (hsa_circ_0027446) promotes the metastasis and epithelial-mesenchymal transition of lung adenocarcinoma cells through the miR-1236-3p/ZEB1 axis.
