circRNA-disease information
Expression pattern:
UP
Associated gene: SH2B1, E-cadherin, Vimentin, Ki67
Associated microRNA: miR-136
Biological function: hsa_circ_0136666 promotes CRC cell proliferation, migration, invasion, cell cycle progression, EMT-mediated invasion, and tumor growth in vivo; knockdown suppresses these malignant phenotypes and arrests cells in G0/G1 phase.
Molecular mechanism: hsa_circ_0136666 functions as a ceRNA/molecular sponge for miR-136, thereby increasing SH2B1 expression and promoting CRC progression.
Biological pathway or process:

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

Detected method:
Q

Validation methods:

RNase R Treatment; RT-qPCR; Microarray; Clinical Sample Validation; Transfection; CCK8; Colony Formation Assay; Cell Cycle Assay; Wound Healing Assay; Transwell Assay; In Vivo Animal Model; IHC (Immunohistochemistry); Luciferase Reporter Assay; RNA Pull-Down; Western Blot; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High hsa_circ_0136666 expression was associated with poor overall survival of patients with CRC, suggesting potential biomarker and therapeutic relevance.

Description:

hsa_circ_0136666 is up-regulated in colorectal cancer tissues and cell lines and high expression predicts poorer overall survival. Functionally, it acts as an oncogenic circRNA that promotes proliferation, migration, invasion, EMT-related changes, cell cycle progression, and xenograft tumor growth. Mechanistically, it sponges miR-136 to increase SH2B1 expression, forming the hsa_circ_0136666/miR-136/SH2B1 regulatory axis.

Confidence score:

0.8354
