cell line-derived xenograft

circRNA-disease information
Expression pattern:
UP
Associated gene: MSI1
Associated microRNA: miR-296-5p
Biological function: promotes tumorigenesis (increases proliferation, promotes cell cycle progression, reduces apoptosis) and suppresses radiosensitivity (promotes survival/colony formation and inhibits radiation-induced apoptosis) in colorectal cancer
Molecular mechanism: ceRNA sponge mechanism: circ_IFT80 sponges miR-296-5p to relieve repression of MSI1, thereby promoting tumorigenesis and radioresistance
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Actinomycin D / DRB Stability Assay; Transfection; MTT; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Colony Formation Assay; Luciferase Reporter Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis; Clinical Sample Validation

Clinical significance:

potential biomarker for diagnosis or treatment for CRC

Description:

circ_IFT80 is up-regulated in CRC patient serum-derived exosomes and CRC cells. It promotes CRC tumorigenesis and radioresistance by acting as a ceRNA sponge for miR-296-5p, thereby increasing MSI1 expression and enhancing proliferation/cell-cycle progression while suppressing apoptosis.

Confidence score:

0.7181
