circRNA-disease information
Expression pattern:
UP
Associated gene: G6PC2, IRS-1
Associated microRNA: hsa-miR-338-3p
Biological function: Aggravates abnormal glucose metabolism and insulin resistance; inhibits glucose uptake; represses IRS-1 activation
Molecular mechanism: Acts as a miRNA sponge for hsa-miR-338-3p to regulate G6PC2 expression and insulin signaling (IRS-1 activation).
Biological pathway or process:

ceRNA regulation (promotes); glucose metabolism (other); insulin resistance (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Sanger Sequencing; FISH / smFISH; Luciferase Reporter Assay; Transfection; Western Blot; Clinical Sample Validation; In Vivo Animal Model; H&E Staining; Bioinformatics Analysis

Clinical significance:

hsa_circ_0046060 was identified as a potential candidate for diagnosing and treating GDM.

Description:

In GDM, exosomal hsa_circ_0046060 is upregulated and aggravates abnormal glucose metabolism/insulin resistance. It functions mainly via a ceRNA mechanism by sponging hsa-miR-338-3p, leading to increased G6PC2 and reduced IRS-1 activation; silencing hsa_circ_0046060 in exosomes reverses these effects in L-02 cells and a diet-induced GDM mouse model.

Confidence score:

0.7759
