Insights

MicroRNAs (miRNAs) regulate gene expression and are linked to animal development and disease. This review discusses their roles in biological processes and genetic disorders.

Area of Science:

  • Molecular Biology
  • Genetics
  • Developmental Biology

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally.
  • They function by binding to messenger RNAs (mRNAs), leading to translational inhibition or mRNA degradation.
  • While numerous miRNAs exist, the functions of many remain uncharacterized.

Purpose of the Study:

  • To review the current literature on the roles of miRNAs in animal development.
  • To discuss the involvement of miRNAs in various diseases, including cancer and genetic disorders.
  • To highlight the significance of miRNA dysregulation in biological processes.

Main Methods:

  • Literature review of scientific publications on miRNAs.
  • Analysis of studies investigating miRNA function in animal models.
  • Examination of research linking miRNA expression patterns to disease states.

Main Results:

  • miRNAs are crucial regulators of fundamental cellular processes such as apoptosis and tissue morphogenesis.
  • Altered miRNA expression signatures are associated with the development and progression of various cancers.
  • Changes in miRNA target sites are implicated as causative factors in certain genetic disorders.

Conclusions:

  • MicroRNAs play integral roles in animal development and are significantly implicated in disease pathogenesis.
  • Further research into miRNA function and dysregulation is essential for understanding and treating diseases.
  • miRNAs represent promising targets for future therapeutic interventions.

MicroRNAs01:22

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...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
lncRNA - Long Non-coding RNAs02:39

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)...
