Research Techniques Made Simple: Studying Circular RNA in Skin Diseases

Area of Science:

• Molecular Biology
• Genomics
• Biochemistry

Background:

• Circular RNAs (circRNAs) are a distinct class of RNA molecules with a covalently closed structure.
• High-throughput sequencing reveals the widespread presence and intricate nature of circRNAs.
• Altered circRNA expression levels are associated with various disease states, notably skin diseases.

Purpose of the Study:

• To summarize protocols for the identification, validation, and characterization of circRNAs.
• To discuss methods for repressing and overexpressing specific circRNAs to investigate their functions.
• To explore the potential role of circRNAs in the pathogenesis of skin diseases.

Main Methods:

• Review of established and emerging protocols for circRNA detection and analysis.
• Description of techniques for experimental manipulation of circRNA levels (repression and overexpression).
• Emphasis on the need for carefully controlled experiments due to similarities between circRNAs and linear RNAs.

Main Results:

• circRNAs exhibit diverse functions, including acting as microRNA inhibitors, protein interactors, and mRNA regulators.
• Specific experimental techniques are crucial for accurate circRNA identification and functional assessment.
• The summarized protocols provide a framework for studying circRNAs in disease contexts.

Conclusions:
