circRNA-disease information
Expression pattern:
UP
Associated gene: ETS1, ACAN, COL2A1
Associated microRNA: -
Biological function: circETS1 is associated with IDD progression; inhibition of circETS1 enhances NPC viability and proliferation, mitigates TNF-alpha-induced apoptosis, promotes extracellular matrix secretion and repair, reduces inflammation, and delays IDD progression.
Molecular mechanism: Silencing circETS1 using si-circETS1 delivered by PLGA microspheres suppresses circETS1 expression without impacting linear ETS1 mRNA, thereby improving NPC activity and extracellular matrix metabolism in IDD models.
Biological pathway or process:

proliferation (inhibits); apoptosis (promotes); inflammation (promotes); other pathway/process (inhibits)

Detected method:

S
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; circRNA-seq; Actinomycin D / DRB Stability Assay; RT-qPCR; FISH / smFISH; IF (Immunofluorescence); Clinical Sample Validation; Transfection; Annexin V/PI Flow Cytometry; IHC (Immunohistochemistry); In Vivo Animal Model; H&E Staining; Bioinformatics Analysis

Clinical significance:

circETS1 could serve as an effective therapeutic target for IDD, and PLGA microspheres loaded with si-circETS1 represent a promising therapeutic strategy.

Description:

This study identified hsa_circ_0002083/circETS1 as an ETS1-derived circRNA up-regulated in severely degenerated human nucleus pulposus tissues and TNF-alpha-induced degenerative NPCs. Functionally, circETS1 appears to aggravate IDD-related NPC dysfunction by suppressing proliferation, promoting apoptosis, and impairing extracellular matrix metabolism, while si-circETS1 delivery using PLGA microspheres suppresses circETS1 and delays IDD progression in vitro and in vivo.

Confidence score:

0.8037
