circRNA-disease information
Expression pattern:
UP
Associated gene: cullin 4A (CUL4A)
Associated microRNA: miR-665
Biological function: circSNTB2 inhibits NP cell proliferation and promotes apoptosis; knockdown of circSNTB2 promotes NP cell proliferation, inhibits apoptosis, alleviates thermo-mechanical pain and NP injury, and delays LDH progression in rats.
Molecular mechanism: circSNTB2 functions as a ceRNA that binds miR-665, thereby regulating the downstream target gene CUL4A and affecting NP cell proliferation and apoptosis.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (inhibits); apoptosis (promotes); inflammation (promotes)

Detected method:
Q
M
Validation methods:

RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Transfection; CCK8; EdU Staining; TUNEL; Annexin V/PI Flow Cytometry; Western Blot; Luciferase Reporter Assay; RNA Pull-Down; In Vivo Animal Model; H&E Staining; ELISA

Clinical significance:

Knockdown of circSNTB2 may be a potential target to protect NP cells from damage and provides a potential idea for targeted therapy of LDH.

Description:

circSNTB2 is up-regulated in NP tissues from LDH patients and in TNF-alpha-treated NP cells. It promotes LDH-related NP cell dysfunction by acting through the miR-665/CUL4A axis, inhibiting NP cell proliferation and promoting apoptosis, while circSNTB2 knockdown alleviates LDH progression in a rat model.

Confidence score:

0.7053
