circRNA-disease information
Expression pattern:
UP
Associated gene: NLRP3
Associated microRNA: miR-942
Biological function: circ_0001438 inhibits proliferation, migration and invasion, and promotes apoptosis and inflammatory responses in HTR-8/Svneo trophoblast cells, contributing to villous trophoblast dysfunction in preeclampsia.
Molecular mechanism: circ_0001438 targets miR-942 and negatively regulates miR-942 expression, thereby activating NLRP3 expression through the circ_0001438/miR-942/NLRP3 regulatory network.
Biological pathway or process:

ceRNA regulation (other); proliferation (inhibits); apoptosis (promotes); migration (inhibits); invasion (inhibits); inflammation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; MTT; Colony Formation Assay; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot

Clinical significance:

circ_0001438 may be a useful biomarker and significant therapeutic biomarker linked to the pathogenesis of PE.

Description:

circ_0001438 is up-regulated in placental tissues from patients with preeclampsia. In HTR-8/Svneo trophoblast cells, circ_0001438 suppresses proliferation, migration and invasion while promoting apoptosis and inflammatory responses. Mechanistically, it acts through the circ_0001438/miR-942/NLRP3 regulatory network and may serve as a therapeutic biomarker for PE.

Confidence score:

0.6536

Other information
Title:

Circ_0001438 participates in the pathogenesis of preeclampsia via the circ_0001438/miR-942/NLRP3 regulatory network.
