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...

Types of RNA

Types of RNA

Overview
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 the regulation of 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.

T Cell Types and Functions

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Cis-regulatory Sequences

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Connective Tissue Cell Types

Connective Tissue Cell Types

Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Background:

Understanding cell-type-specific gene expression is crucial for deciphering tissue and organ biology.
Existing methods for cell-specific transcriptomics often involve laborious cell sorting or isolation techniques.

Purpose of the Study:

To develop and validate a streamlined method for cell-specific transcriptomics.
To enable the analysis of newly synthesized RNA in specific cell types within intact tissues.

Main Methods:

Integration of metabolic RNA labeling (thiouracil tagging) with SLAMseq (thiol (SH)-linked alkylation for the metabolic sequencing of RNA).
Utilizing transgenic mice expressing cell-type-specific uracil phosphoribosyltransferase (UPRT) for targeted RNA labeling.
Employing SLAM-DUNK software for mapping RNA sequencing reads with T>C conversions to identify labeled transcripts.

Main Results:

The SLAM-ITseq method successfully identifies cell-specific transcriptomes from total RNA pools.
Demonstrated identification of approximately 5,000 genes expressed in a specific cell type.
The protocol is adaptable and can be completed within 5 days.

Conclusions:

SLAM-ITseq offers a powerful, efficient, and accessible approach for cell-specific transcriptomics.
This method eliminates the need for cell sorting, simplifying the study of gene expression dynamics.
The technique facilitates deeper insights into the molecular mechanisms of multicellular organisms.
