Potential Diagnostic Value of Circular RNA hsa_circ_0008882 in Rheumatic Valvular Heart Disease

Area of Science:

• Cardiovascular Research
• Molecular Biology
• Biomarker Discovery

Background:

• Rheumatic valvular heart disease (RVHD) poses a significant global health challenge.
• The underlying pathogenesis and reliable diagnostic markers for RVHD require further elucidation.
• Circular RNAs (circRNAs) are emerging as critical regulators in various diseases, including cardiovascular conditions.

Purpose of the Study:

• To investigate the role of circRNAs in RVHD pathogenesis.
• To evaluate hsa_circ_0008882 as a potential diagnostic biomarker for RVHD.
• To explore the underlying molecular mechanisms of hsa_circ_0008882 in RVHD.

Main Methods:

• Expression analysis of circRNAs in RVHD patient samples (plasma and valve tissues).
• Correlation analysis between hsa_circ_0008882 levels and clinical-pathological characteristics.
• Diagnostic value assessment using ROC analysis.
• Mechanistic studies including dual luciferase reporter assays to validate interactions.

Main Results:

• Hsa_circ_0008882 expression was significantly upregulated in RVHD plasma and tissues.
• Plasma hsa_circ_0008882 showed moderate diagnostic ability (AUC=0.707) and correlated with disease severity.
• Hsa_circ_0008882 was identified as an independent risk factor for RVHD and interacts with hsa-miR-4739.

Conclusions:

• Hsa_circ_0008882 plays a crucial role in the pathogenesis of RVHD.
• Plasma hsa_circ_0008882 holds potential as an auxiliary diagnostic indicator for RVHD.
• Further research into circRNA-mediated mechanisms in RVHD is warranted.
