circRNA-disease information
Expression pattern:
UP
Associated gene: HMGB3
Associated microRNA: miR-145-5p, miR-338-3p
Biological function: circ_PSD3 promotes PTC cell proliferation, migration, invasion and EMT; circ_PSD3 knockdown suppresses proliferation, migration and invasion.
Molecular mechanism: circ_PSD3 acts as a ceRNA sponge for miR-145-5p and miR-338-3p, thereby regulating HMGB3 expression and promoting malignant behavior and EMT in PTC.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Luciferase Reporter Assay; Transfection; CCK8; Transwell Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

circ_PSD3 expression was associated with lymph node metastasis, TNM stage and tumor volume, and may be a potential therapeutic target for PTC.

Description:

circ_PSD3 is up-regulated in papillary thyroid carcinoma tissues and cells and functions as an oncogenic circRNA. It promotes PTC cell proliferation, migration, invasion and EMT by sponging miR-145-5p and miR-338-3p, thereby enhancing HMGB3 expression. Its expression is associated with lymph node metastasis, TNM stage and tumor volume, suggesting potential clinical relevance.

Confidence score:

0.7129
