circRNA-disease information
Expression pattern:
UP
Associated gene: EGFR, CCNE1, PIK3CD, Ki-67
Associated microRNA: miR-7
Biological function: Promotes tumor progression and cell growth/proliferation; inhibits apoptosis; promotes G1/S cell-cycle progression in NSCLC.
Molecular mechanism: Acts as a miR-7 sponge (ceRNA) to up-regulate miR-7 target genes (EGFR, CCNE1, PIK3CD), antagonizing miR-7 tumor-suppressive effects.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model; Survival Analysis; Luciferase Reporter Assay; Bioinformatics Analysis

Clinical significance:

High CDR1as expression is associated with higher TNM stage, lymph node metastasis, and shorter overall survival; CDR1as is an independent prognostic factor in NSCLC.

Description:

CDR1as is up-regulated in NSCLC and acts as an oncogenic circRNA. It sponges miR-7, thereby up-regulating miR-7 targets (EGFR, CCNE1, PIK3CD) to promote proliferation/cell growth and inhibit apoptosis, and its high expression predicts poorer overall survival.

Confidence score:

0.7408
