circRNA-disease information
Expression pattern:
UP
Associated gene: NEK4
Associated microRNA: miR-485-3p
Biological function: circ-MEMO1 promotes LUAD cell viability, cell cycle progression, proliferation, migration and invasion under propofol treatment, and its overexpression attenuates propofol-induced anti-growth and anti-metastasis effects.
Molecular mechanism: circ-MEMO1 acts as a ceRNA that sponges miR-485-3p to regulate NEK4, thereby weakening propofol-induced tumor-suppressive effects in LUAD cells.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); cell cycle (promotes); migration (promotes); invasion (promotes); metastasis (promotes); drug resistance (other)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; MTT; EdU Staining; Cell Cycle Assay; Transwell Assay; Western Blot; Luciferase Reporter Assay; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High circ-MEMO1 expression was associated with low 5-year overall survival and with tumor size, TNM stage, lymph node metastasis, and differentiation grade in LUAD patients.

Description:

circ-MEMO1 is up-regulated in LUAD tissues and LUAD cell lines and high expression is linked to poorer overall survival. In vitro, circ-MEMO1 overexpression counteracts propofol-induced suppression of LUAD cell growth, migration and invasion by sponging miR-485-3p and regulating NEK4 within a ceRNA axis.

Confidence score:

0.7126
