circRNA-disease information
Expression pattern:
UP
Associated gene: SLC7A11
Associated microRNA: miR-1261
Biological function: Promotes HCC cell proliferation, invasion, tumor growth and metastasis; knockdown promotes ferroptosis.
Molecular mechanism: ceRNA mechanism: circ0097009 sponges miR-1261 to regulate SLC7A11, affecting ferroptosis (system Xc- and GPX4-related).
Biological pathway or process:

ferroptosis (inhibits); proliferation (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Clinical Sample Validation; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model; H&E Staining; Bioinformatics Analysis

Clinical significance:

Circ0097009 may be used as a diagnostic biomarker for HCC and as a potential target for HCC therapy.

Description:

circ0097009 (hsa_circ_0097009), derived from SLC5A8, is up-regulated in HCC tissues and cell lines and promotes malignant phenotypes (proliferation, invasion, tumor growth and metastasis). Mechanistically, it sponges miR-1261 to de-repress SLC7A11, thereby inhibiting ferroptosis (system Xc- and GPX4-related) and facilitating HCC progression.

Confidence score:

0.8442

Title:

Ferroptosis is involved in the progression of hepatocellular carcinoma through the circ0097009/miR-1261/SLC7A11 axis.
