circRNA-disease information
Expression pattern:
UP
Associated gene: NOTCH1 mRNA, NOTCH1
Associated microRNA: miR-193b-3p
Biological function: Promotes T-ALL cell proliferation and cell cycle progression, and represses T-ALL cell apoptosis.
Molecular mechanism: circ_0000745 acts as a miR-193b-3p sponge/decoy to upregulate NOTCH1 expression, thereby promoting proliferation and inhibiting apoptosis in T-ALL cells.
Biological pathway or process:

Notch (promotes); proliferation (promotes); apoptosis (inhibits); cell cycle (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Western Blot; Bioinformatics Analysis

Clinical significance:

circ_0000745 expression was associated with LDH level and risk stratification in T-ALL clinical samples.

Description:

hsa_circ_0000745/circ_0000745 is up-regulated in T-ALL bone marrow and T-ALL cell lines. It promotes proliferation and cell cycle progression while suppressing apoptosis by sponging miR-193b-3p, relieving repression of NOTCH1 mRNA/protein expression. Its expression is associated with clinical pathological parameters including LDH level and risk stratification.

Confidence score:

0.7795
