Research Progress on MicroRNA in Forensic Medicine as Molecular Markers

Area of Science:

• Forensic science
• Molecular biology
• Genomics

Background:

• MicroRNAs (miRNAs) are endogenous non-coding small RNAs (18-24 nucleotides).
• miRNA expression is conserved, time-dependent, and tissue-specific.
• miRNAs are resistant to degradation by RNase and environmental factors (temperature, pH).

Purpose of the Study:

• To summarize the forensic applications of miRNA.
• To highlight miRNA's potential in forensic investigations.

Main Methods:

• Review of existing literature on miRNA applications in forensic science.
• Analysis of miRNA stability and detectability in various conditions.

Main Results:

• miRNAs are detectable even in degraded tissues.
• miRNA properties make them suitable for forensic analysis.
• Potential applications include body fluid identification, postmortem interval estimation, and cause of death analysis.

Conclusions:

• miRNAs offer a promising tool for forensic investigations.
• Further research can expand miRNA's role in forensic medicine.
