circRNA-disease information
Expression pattern:
UP
Associated gene: Diaphanous Homolog 1, DIAPH1
Associated microRNA: miR-665
Biological function: Circ_0044556 functions as an oncogenic circRNA in colorectal cancer, promoting cell proliferation, cell cycle progression, migration, invasion, EMT, and tumor growth.
Molecular mechanism: Circ_0044556 acts as a miR-665 sponge to upregulate DIAPH1 expression, thereby promoting CRC progression.
Biological pathway or process:

proliferation (promotes); cell cycle (promotes); migration (promotes); invasion (promotes); EMT (promotes); metastasis (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

Actinomycin D / DRB Stability Assay; RNase R Treatment; RT-qPCR; Clinical Sample Validation; Transfection; CCK8; EdU Staining; Cell Cycle Assay; Western Blot; Transwell Assay; Luciferase Reporter Assay; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

circ_0044556 might be an efficient biomarker to improve the management of diagnosis and treatment in CRC.

Description:

circ_0044556 is up-regulated in colorectal cancer tissues and cell lines and acts as an oncogenic circRNA. It promotes CRC proliferation, cell cycle progression, migration, invasion, EMT, and tumor growth by sponging miR-665 and increasing DIAPH1 expression. The study also suggests circ_0044556 may serve as a biomarker for CRC diagnosis and treatment management.

Confidence score:

0.7595
