What is Gene Expression?01:36

What is Gene Expression?

12.0K
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised  of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein

piRNA - Piwi-interacting RNAs

7.8K
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...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

1.5K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

38.5K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

26.8K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Summary

Pseudogene RNAs act as competitive endogenous RNAs (ceRNAs) by sponging microRNAs (miRNAs). This ceRNA network regulates gene expression, impacting parental gene activity through miRNA sequestration.

Area of Science:

  • Molecular Biology
  • Genetics
  • RNA Biology

Background:

  • The competitive endogenous RNA (ceRNA) hypothesis posits that RNA transcripts interact through shared microRNA (miRNA) response elements (MREs).
  • Pseudogene RNAs are recognized as key players in ceRNA networks, potentially regulating parental gene expression.

Purpose of the Study:

  • To review the mechanism by which pseudogene transcripts regulate parental gene expression via the ceRNA network.
  • To discuss the biological significance of pseudogene-mediated ceRNA regulation.

Main Methods:

  • Review of existing literature on ceRNA mechanisms and pseudogene functions.
  • Analysis of RNA-RNA interactions through miRNA binding and MREs.

Main Results:

  • Pseudogene RNAs can sequester miRNAs, thereby alleviating repression on their target mRNAs, including parental genes.
  • The ceRNA network involves a complex interplay of various RNA types (mRNA, lncRNA, pseudogenes, etc.) through competitive miRNA binding.

Conclusions:

  • Pseudogene transcripts play a significant role in gene regulation through the ceRNA network.
  • Understanding the ceRNA network is crucial for elucidating complex gene expression regulation and its biological implications.
