Summary
Extracellular microRNAs (miRNAs) are promising non-invasive biomarkers for endocrine and metabolic diseases. This review covers their origins, roles, and challenges in diagnostic applications.
Area of Science:
- Endocrinology
- Molecular Biology
- Biochemistry
Background:
- Endocrine disorders require specific, sensitive, and non-invasive biomarkers.
- MicroRNAs (miRNAs) are key regulators of gene expression, often dysregulated in metabolic and endocrine diseases.
- Extracellular miRNAs are secreted into biofluids and mediate intercellular communication.
Purpose of the Study:
- To review the characteristics of extracellular miRNAs.
- To summarize their origin and roles in endocrine and metabolic diseases.
- To discuss challenges and future perspectives for their use as biomarkers.
Main Methods:
- Literature review of studies on extracellular miRNAs.
- Analysis of miRNA biogenesis and secretion.
- Evaluation of miRNA detection and measurement techniques.
Main Results:
- Extracellular miRNAs are protected in biofluids, making them suitable biomarker candidates.
- Dysregulated miRNAs are implicated in various endocrine and metabolic conditions.
- Significant technical challenges exist in identifying and quantifying circulating miRNAs.
Conclusions:
- Extracellular miRNAs hold significant potential as diagnostic and prognostic biomarkers for endocrine and metabolic diseases.
- Further research is needed to overcome technical hurdles and validate their clinical utility.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
