circRNA-disease information
Expression pattern:
UP
Associated gene: LASP1, METTL3
Associated microRNA: miR-1184
Biological function: Promotes CRC cell proliferation, migration, invasion, tumor formation and radioresistance; inhibits apoptosis.
Molecular mechanism: METTL3-mediated m6A modification of circ_0124554 promotes CRC progression and radioresistance by inducing LASP1 expression through interaction with miR-1184.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); radioresistance (promotes); m6A modification (other); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Transfection; EdU Staining; Annexin V/PI Flow Cytometry; Transwell Assay; Colony Formation Assay; In Vivo Animal Model; IHC (Immunohistochemistry); Luciferase Reporter Assay; MeRIP / MeRIP-seq; Western Blot; Bioinformatics Analysis

Clinical significance:

Potential target to improve radiosensitivity of CRC.

Description:

circ_0124554 is upregulated in colorectal cancer tissues and cells. It promotes CRC proliferation, migration, invasion, tumor growth and radioresistance while suppressing apoptosis. Mechanistically, METTL3-mediated m6A modification increases circ_0124554, which acts through the miR-1184/LASP1 axis to drive malignant phenotypes and resistance to radiation.

Confidence score:

0.8005
