MicroRNAs

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...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique helps...

Background:

Microarray analysis is a common method for identifying microRNA targets.
Microarrays have technical limitations in assessing transcript levels accurately.
Exploring microRNA targetomes requires precise transcriptomic data.

Purpose of the Study:

To evaluate the utility of next-generation sequencing (NGS) for microRNA target identification.
To compare NGS with microarray platforms for microRNA targetome analysis.
To investigate the role of transcript structure in microRNA-mediated gene regulation.

Main Methods:

Illumina-based high-throughput multiplexed NGS was used to analyze transcriptome changes.
Transcriptome data was analyzed to infer the microRNA targetome.
NGS results were compared with 3' UTR reporter assay data.
Transcript structure information from NGS data was used to investigate discordant results.

Main Results:

NGS identified a larger microRNA targetome compared to microarray studies.
General concordance was observed between NGS and 3' UTR reporter data.
Transcript structure significantly influences microRNA targeting efficacy and failure.

Conclusions:

NGS provides a more accurate and comprehensive approach to microRNA target identification than microarrays.
NGS is valuable for studying microRNA biology and mechanisms of action.
Understanding transcript structure is crucial for interpreting microRNA targeting effects.
