TRIM8-associated non-coding RNA panel as a biomarker for Lupus nephritis activity

Area of Science:

• Molecular biology
• Immunology
• Biomarker discovery

Background:

• Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE).
• Accurate biomarkers for assessing LN activity are crucial for effective patient management.
• Current diagnostic methods for LN activity can be invasive.

Purpose of the Study:

• To evaluate the TRIM8 gene and its associated non-coding RNAs (lnc-SSBP2-1:1 and hsa-miR-126-5p) as potential non-invasive biomarkers for LN activity.
• To investigate the diagnostic and prognostic value of these molecular markers in LN.

Main Methods:

• Bioinformatics analyses were used to identify candidate mRNA and non-coding RNAs (ncRNAs) in LN.
• Expression levels of TRIM8, lnc-SSBP2-1:1, and hsa-miR-126-5p were quantified using real-time PCR.
• Samples were analyzed from patients with active LN, inactive LN, and healthy controls.

Main Results:

• TRIM8 mRNA and lnc-SSBP2-1:1 lncRNA were significantly upregulated in active LN patients.
• hsa-miR-126-5p was significantly downregulated in active LN patients.
• Disease activity scores (SLEDAI-2K) correlated with the expression levels of these markers.

Conclusions:

• The TRIM8-associated non-coding RNA regulatory network shows potential as a biomarker for LN activity.
• These findings suggest a novel, non-invasive approach for monitoring LN.
• This research may lead to improved clinical management strategies for patients with lupus nephritis.
