Cell Specific Gene Expression

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

What is Gene Expression?

What is Gene Expression?

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
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

What is Gene Expression?

What is Gene Expression?

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...

Chromatin Position Affects Gene Expression

Chromatin Position Affects Gene Expression

Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

mRNA Stability and Gene Expression

mRNA Stability and Gene Expression

The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

Area of Science:

Developmental Biology
Genomics
Molecular Biology

Background:

The Drosophila wing disc is a key model for studying developmental processes and signaling pathways.
A comprehensive gene expression map of the wing disc is currently unavailable.

Purpose of the Study:

To generate a gene expression atlas for the Drosophila wing disc.
To develop a novel method for analyzing single-cell RNA sequencing (scRNA-seq) data to create spatial expression maps.

Main Methods:

Employed single-cell RNA sequencing (scRNA-seq) on Drosophila wing discs.
Developed a novel scRNA-seq data analysis method based on gene expression correlations, bypassing traditional cell mapping.
Computed genome-wide expression maps for all detected genes within the wing disc.

Main Results:

Successfully generated a gene expression atlas for the Drosophila wing disc.
Discovered 824 genes exhibiting spatially restricted expression patterns.
Identified clusters of genes with similar expression patterns and functional relevance.
Characterized the previously unstudied gene CG5151, demonstrating its role in regulating Wnt signaling.

Conclusions:

The developed method enables the creation of comprehensive gene expression atlases from scRNA-seq data for undifferentiated tissues.
This approach significantly advances the study of developmental processes by providing spatial gene expression information.
The identified spatially restricted genes and the characterization of CG5151 offer new insights into wing disc development and signaling.
