Circ_0088212 Targeting miR-576-5p/FKBP1A Axis Inhibits Osteosarcoma Progression

Area of Science:

• Oncology
• Molecular Biology
• Gene Regulation

Background:

• Circular RNAs (circRNAs) are key gene expression regulators.
• The specific role of circRNAs in osteosarcoma (OS) requires further elucidation.

Purpose of the Study:

• To investigate the function of circ_0088212 in osteosarcoma (OS).

Main Methods:

• Quantification of circ_0088212, miR-576-5p, and FKBP1A via qRT-PCR.
• Cellular function assays (proliferation, migration, apoptosis) and in vivo xenograft experiments.
• Western blotting for apoptosis-related proteins (Bcl-2, Bax) and dual-luciferase/RNA immunoprecipitation assays to confirm molecular interactions.

Main Results:

• circ_0088212 expression was downregulated in OS cells and tissues.
• Overexpression of circ_0088212 inhibited OS cell proliferation and migration, and increased apoptosis.
• circ_0088212 overexpression suppressed tumor growth in vivo, mediated by the miR-576-5p/FKBP1A axis.

Conclusions:

• circ_0088212 acts as a tumor suppressor in osteosarcoma.
• The miR-576-5p/FKBP1A axis is a key downstream pathway regulated by circ_0088212 in OS.
• circ_0088212 holds potential as a therapeutic target for osteosarcoma.
