Ribosome Profiling02:24

Ribosome Profiling

3.5K
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...

Gene Evolution - Fast or Slow?

7.1K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

RNA-seq03:21

RNA-seq

9.9K
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...

Area of Science:

  • Molecular Biology
  • Genetics
  • Bioinformatics

Background:

  • Biological research often yields gene lists, but understanding gene function is challenging.
  • Systematic prioritization of genes for study is needed to accelerate biological discovery.

Purpose of the Study:

  • To develop and illustrate an approach for prioritizing genes for detailed study using limited resources.
  • To identify understudied genes involved in RNA silencing and their potential regulatory roles.

Main Methods:

  • Utilized RNA silencing in *C. elegans* to perturb gene function.
  • Applied mutual information to capture gene relationships and cluster frequently identified yet understudied genes.
  • Predicted protein-protein interactions for candidate regulators.

Main Results:

  • Identified understudied genes whose products may interact with known RNA silencing regulators, suggesting feedback loops.
  • Discovered links between RNA silencing and processes like cell cycle and asymmetric cell division.
  • Demonstrated that analyzing perturbed transcripts can identify candidate protein-protein interactions.

Conclusions:

  • The developed approach effectively prioritizes genes for further investigation.
  • RNA sequencing and interaction prediction can uncover novel regulators and cellular process connections.
  • This method aids in understanding gene function and regulatory networks in biological systems.
