circRNA-disease information
Expression pattern:
UP
Associated gene: COL1A1
Associated microRNA: miR-193a-5p
Biological function: promotes colorectal cancer cell stemness and tumor-initiating ability
Molecular mechanism: acts as a ceRNA to sponge miR-193a-5p and upregulate COL1A1 in a miR-193a-5p-dependent manner
Biological pathway or process:

stemness (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Clinical Sample Validation; Survival Analysis; FISH / smFISH; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; Transfection; RNA Pull-Down; Luciferase Reporter Assay; CCK8; Western Blot; Colony Formation Assay; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

correlated with TNM stage, depth of invasion, lymphatic metastasis and distant metastasis; high hsa_circ_0001806 level associated with lower overall survival

Description:

hsa_circ_0001806 is upregulated in colorectal cancer and promotes cancer cell stemness and tumor-initiating ability. It functions as a ceRNA by sponging miR-193a-5p to relieve repression of COL1A1, forming a hsa_circ_0001806/miR-193a-5p/COL1A1 axis associated with advanced clinicopathologic features and poorer overall survival.

Confidence score:

0.8625
