circRNA-disease information
Expression pattern:
UP
Associated gene: ROCK1
Associated microRNA: miR-532-3p
Biological function: promotes high glucose-induced HK-2 cell injury (oxidative stress, apoptosis, fibrosis) and inhibits proliferation
Molecular mechanism: ceRNA mechanism: circ_0000064 sponges miR-532-3p, relieving repression of ROCK1
Biological pathway or process:

ceRNA regulation (other); apoptosis (promotes); proliferation (inhibits); fibrosis (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Western Blot; Clinical Sample Validation; Bioinformatics Analysis

Clinical significance:

circ_0000064 was increased in serum of DN patients and was higher in macroalbuminuria than microalbuminuria, suggesting association with DN progression

Description:

circ_0000064 is up-regulated in DN patient serum and in HG-treated HK-2 cells, and it aggravates HG-induced renal tubular epithelial cell injury (oxidative stress, apoptosis and fibrosis) while suppressing proliferation. Mechanistically, it functions as a ceRNA by sponging miR-532-3p to increase ROCK1, and knockdown of circ_0000064 alleviates injury via the miR-532-3p/ROCK1 axis.

Confidence score:

0.7045

Other information
Title:

Circ_0000064 promotes high glucose-induced renal tubular epithelial cells injury to facilitate diabetic nephropathy progression through miR-532-3p/ROCK1 axis.
