circRNA-disease information
Expression pattern:
UP
Associated gene: RPN2
Associated microRNA: miR-1258
Biological function: promotes CRC cell proliferation, invasion, and tumor growth
Molecular mechanism: circ_SMAD2 sponges miR-1258 to upregulate RPN2 expression
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); invasion (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; RNase R Treatment; divergent primers PCR; Nuclear-Cytoplasmic Fractionation; RNA Pull-Down; Luciferase Reporter Assay; FISH / smFISH; Transfection; CCK8; Cell Cycle Assay; Colony Formation Assay; Transwell Assay; In Vivo Animal Model; Western Blot; Bioinformatics Analysis; Clinical Sample Validation; Survival Analysis

Clinical significance:

High circ_SMAD2 levels were positively correlated with CRC clinicopathological features; elevated circ_SMAD2 levels were correlated with advanced clinical features and poor CRC prognosis

Description:

In colorectal cancer, circ_SMAD2 (hsa_circ_0000847) is up-regulated and promotes proliferation, invasion, and in vivo tumor growth. It mainly acts as a ceRNA by sponging miR-1258, thereby increasing RPN2 expression and driving CRC progression.

Confidence score:

0.8539

Title:

circ_SMAD2 regulate colorectal cancer cells proliferation through targeting miR-1258/RPN2 signaling pathway.
