Ribosome Profiling02:24

Ribosome Profiling

3.2K
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...

RNA-seq03:21

RNA-seq

9.4K
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...

lncRNA - Long Non-coding RNAs

7.5K
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...

Types of RNA01:20

Types of RNA

13.9K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Experimental RNAi02:15

Experimental RNAi

6.5K
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...

RNA Interference01:23

RNA Interference

24.3K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Area of Science:

  • Genetics
  • Molecular Biology
  • Developmental Biology

Background:

  • Long noncoding RNAs (lncRNAs) are transcripts longer than 200 nucleotides.
  • The functions of many lncRNAs remain largely uncharacterized.
  • Understanding lncRNA roles is essential for deciphering gene regulation.

Purpose of the Study:

  • To investigate the functional roles of specific long noncoding RNA molecules.
  • To determine the involvement of lncRNAs in developmental processes using genetic models.

Main Methods:

  • Utilized genetic knockout techniques in a mouse model.
  • Analyzed developmental phenotypes resulting from the absence of specific lncRNAs.
  • Employed molecular biology methods to assess gene expression changes.

Main Results:

  • Genetic ablation of certain long noncoding RNAs led to observable developmental defects in mice.
  • Confirmed that specific lncRNAs are essential for normal embryonic development.
  • Identified key developmental pathways regulated by the studied lncRNAs.

Conclusions:

  • Long noncoding RNAs possess critical developmental functions.
  • Genetic knockout studies provide robust evidence for the necessity of lncRNAs in development.
  • Further research into lncRNA function can reveal new therapeutic targets.
