circRNA-disease information
Expression pattern:
UP
Associated gene: CREB1
Associated microRNA: miR-384
Biological function: promotes GC cell proliferation, migration and invasion; promotes cell cycle progression; inhibits apoptosis; promotes tumor growth in vivo
Molecular mechanism: ceRNA mechanism: circ_0043947 sponges miR-384 to upregulate CREB1
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); cell cycle (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Back-Splice Junction PCR / divergent primers PCR; RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Colony Formation Assay; Wound Healing Assay; Transwell Assay; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model; Clinical Sample Validation; Survival Analysis; Bioinformatics Analysis

Clinical significance:

high circ_0043947 expression was significantly related to the low overall survival of GC patients; correlated with advanced TNM stage, lymph node metastasis and distant metastasis

Description:

Circ_0043947 is up-regulated in gastric cancer tissues and cells and functions as an oncogenic circRNA. It sponges miR-384 to increase CREB1 expression, thereby promoting proliferation, migration/invasion, cell-cycle progression and tumor growth while suppressing apoptosis; high expression is associated with worse overall survival.

Confidence score:

0.8593
