Summary
Circular RNAs (circRNAs) show abnormal regulation in vulvar lichen sclerosus (VLS). This study identified differentially expressed circRNAs, suggesting their role in VLS pathogenesis and disease progression.
Area of Science:
- Gynecology
- Molecular Biology
- Genetics
Background:
- Vulvar lichen sclerosus (VLS) is a common vulvar condition affecting women.
- Thirteen percent of women experience symptomatic vulvar diseases.
Purpose of the Study:
- To investigate the expression profile of circular RNAs (circRNAs) in VLS tissues.
- To identify core genes involved in the pathogenesis of VLS.
Main Methods:
- RNA sequencing was performed on 20 VLS tissue samples and 20 healthy vulvar skin samples after rRNA removal.
- Differential expression analysis was conducted for messenger RNAs (mRNAs), long non-coding RNAs (lncRNAs), and circRNAs.
- Bioinformatics analysis was employed to explore the potential functions of differentially expressed RNAs.
Main Results:
- A total of 79 differentially expressed circRNAs were identified in VLS, with 54 up-regulated and 25 down-regulated.
- Differentially expressed circRNAs were associated with biological processes and molecular functions.
- Key signaling pathways implicated include "human T-cell leukemia virus 1 infection" and "axon guidance".
Conclusions:
- An abnormal circRNA expression profile is characteristic of VLS.
- Dysregulation of circRNAs is potentially linked to the pathogenesis and pathological processes of VLS.
