circRNA-disease information
Expression pattern:
UP
Associated gene: HTRA1 / HtrA serine peptidase 1 / HtrA Serine Peptidase 1, E-cadherin, N-cadherin
Associated microRNA: miR-188-3p
Biological function: Restrains trophoblast cell proliferation, invasion, migration and EMT, and induces apoptosis in JEG-3 and HTR8/SVneo cells.
Molecular mechanism: circ_0001326 acts as a sponge for miR-188-3p and regulates HTRA1 through sequestering miR-188-3p.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Annexin V/PI Flow Cytometry; Transwell Assay; Wound Healing Assay; Western Blot; ROC Analysis; Bioinformatics Analysis

Clinical significance:

circ_0001326 had high diagnostic value for PE; high circ_0001326 expression was associated with higher proteinuria, systolic blood pressure and diastolic blood pressure.

Description:

circ_0001326 is up-regulated in placental tissues from patients with preeclampsia and shows diagnostic value for distinguishing PE placentae from normal placentae. In trophoblast cells, circ_0001326 overexpression suppresses proliferation, invasion, migration and EMT while promoting apoptosis. Mechanistically, circ_0001326 functions through the miR-188-3p/HTRA1 axis by sponging miR-188-3p to regulate HTRA1.

Confidence score:

0.7859
