circRNA-disease information
Expression pattern:
UP
Associated gene: PLEK2
Associated microRNA: miR-138-5p
Biological function: Promotes NSCLC malignant phenotype, tumor growth and Warburg effect; promotes proliferation, migration, invasion, glucose uptake and lactate production; inhibits apoptosis.
Molecular mechanism: circCNKSR2 functions as a miR-138-5p sponge and indirectly modulates PLEK2 expression, thereby promoting NSCLC progression and Warburg effect.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); glycolysis (promotes); ceRNA regulation (promotes); other pathway/process (promotes)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; Transfection; CCK8; Annexin V/PI Flow Cytometry; Transwell Assay; Luciferase Reporter Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

circCNKSR2 may serve as a potential molecular biomarker and diagnostic marker for NSCLC.

Description:

circCNKSR2 is up-regulated in NSCLC tissues and cells and mainly localized in the cytoplasm. It promotes NSCLC tumorigenesis, malignant cell behaviors and Warburg effect by sponging miR-138-5p and thereby increasing PLEK2 expression. The study suggests circCNKSR2 may be a diagnostic biomarker and therapeutic target for NSCLC.

Confidence score:

0.7795
