Identification of microRNAs Derived from Transposable Elements in the Macaca mulatta (Rhesus Monkey) Genome

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Background:

• Transposable elements (TEs) are mobile DNA sequences that can influence genome evolution.
• MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
• Some miRNAs originate from TEs, termed miRNAs derived from TEs (MDTEs), and can act as regulatory elements.

Purpose of the Study:

• To identify MDTEs in the Macaca mulatta (rhesus monkey) genome.
• To investigate the expression and functional implications of identified MDTEs.

Main Methods:

• Genome-wide identification of MDTEs using miRNA and TE coordinates.
• Quantitative polymerase chain reaction (qPCR) to examine MDTE expression.
• Gene Ontology (GO) analysis for putative target gene functions.

Main Results:

• Seventeen MDTEs were identified exclusively in the Macaca mulatta genome.
• Expression analysis of five selected MDTEs was performed.
• Functional enrichment analysis of target genes provided insights into MDTE roles.

Conclusions:

• MDTEs represent a significant source of regulatory small RNAs in the rhesus monkey genome.
• These findings contribute to understanding the evolutionary impact of TEs on host gene regulation.
• Further research can elucidate the specific roles of MDTEs in primate biology.
