Summary
Pseudogenes can act as competitive endogenous RNAs (ceRNAs) to regulate gene expression. This study details methods for predicting and experimentally validating pseudogene ceRNA targets.
Area of Science:
- Molecular Biology
- Genomics
- Bioinformatics
Background:
- Pseudogenes, once considered non-functional, are increasingly recognized for their regulatory roles.
- One key mechanism involves pseudogenes acting as competitive endogenous RNAs (ceRNAs).
- ceRNAs sequester microRNAs (miRNAs), thereby influencing the expression of miRNA target genes.
Purpose of the Study:
- To provide a comprehensive guide for predicting pseudogene ceRNA targets.
- To outline experimental validation strategies for identified pseudogene ceRNA interactions.
Main Methods:
- Bioinformatic approaches for predicting potential pseudogene ceRNA targets.
- Experimental techniques for validating ceRNA activity and target interactions.
Main Results:
- The study outlines a framework for identifying pseudogene ceRNA networks.
- It emphasizes the importance of both computational prediction and experimental validation.
Conclusions:
- Pseudogene ceRNAs represent a significant layer of gene expression regulation.
- Understanding these mechanisms is crucial for deciphering complex cellular processes and disease pathologies.

3.8K
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.

02:57piRNA - Piwi-interacting RNAs
7.2K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

02:15Experimental RNAi
6.6K
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...

01:23RNA Interference
26.9K
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...

6.7K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

02:28Leaky Scanning
5.3K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...
