circRNA-disease information
Expression pattern:
UP
Associated gene: PDK1, BCL11A, Ago2
Associated microRNA: miR-1231
Biological function: promotes NKTL progression and glycolysis (glucose uptake and lactate production)
Molecular mechanism: circKIF4A acts as a ceRNA/miRNA sponge for miR-1231 to regulate PDK1 and BCL11A expression
Biological pathway or process:

glycolysis (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Nuclear-Cytoplasmic Fractionation; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; In Vivo Animal Model; IHC (Immunohistochemistry); Clinical Sample Validation; Cohort Study; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High circKIF4A levels predict poorer OS and PFS and circKIF4A expression is an independent prognostic indicator of NKTL

Description:

circKIF4A is up-regulated in NKTL and high expression is associated with worse OS/PFS. Functionally, circKIF4A promotes NKTL glycolysis (glucose uptake and lactate production) by acting as a ceRNA that sponges miR-1231, thereby increasing PDK1 and BCL11A expression.

Confidence score:

0.8487
