Insights

MicroRNAs (miRNAs) are increasingly linked to diseases. This study reveals patterns in miRNA-disease links, finding miRNAs show similar dysfunction evidence for similar diseases and uncovering correlations between miRNA tissue-specificity, conservation, and disease association.

Area of Science:

  • Genomics
  • Molecular Biology
  • Bioinformatics

Background:

  • MicroRNAs (miRNAs) are implicated in various diseases, but the underlying association patterns are not well understood.
  • Understanding these patterns is crucial for disease diagnosis and therapeutic strategies.

Purpose of the Study:

  • To comprehensively analyze human miRNA-disease association data.
  • To identify and dissect underlying patterns in these associations.
  • To build a human miRNA-disease association network.

Main Methods:

  • Manual collection and curation of human miRNA-disease association data from scientific literature.
  • Construction of a human miRNA-disease association network.
  • Bioinformatic analysis of network properties, miRNA tissue-specificity, conservation, and grouping.

Main Results:

  • miRNAs exhibit similar or distinct dysfunctional evidence correlating with similar or different disease clusters.
  • A negative correlation exists between miRNA tissue-specificity and the number of associated diseases.
  • Associations were observed between miRNA conservation and disease linkage.
  • miRNAs linked to the same disease often belong to predefined miRNA groups.

Conclusions:

  • The study elucidates key patterns in miRNA-disease associations, providing insights into their biological significance.
  • Findings suggest potential for identifying novel disease-associated miRNAs based on network properties and miRNA characteristics.

MicroRNAs

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...

Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
