Synthetic Biology

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

The Eukaryotic Promoter Region

The Eukaryotic Promoter Region

The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences. The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

Conservative Site-specific Recombination and Phase Variation

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Reporter Genes

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Area of Science:

Molecular Biology
Synthetic Biology
Genomics

Background:

Synthetic promoters mediate specific gene expression.
Current methods involve random combination of cis-regulatory regions.
Selection of active sequences is typically performed in target cell lines.

Purpose of the Study:

To develop a novel approach for constructing synthetic promoters.
To utilize gene expression profiles from microarray datasets for cis-regulatory element selection.
To create synthetic promoters with enhanced specificity for target cells, such as colorectal cancer cells.

Main Methods:

Gene expression profiles from microarray datasets were used to select cis-regulatory elements.
A new selection criteria was developed based on target cell transcriptome, cis-regulatory sequence frequency in gene modules, and region length.
Synthetic promoter libraries were constructed using this data-driven approach.

Main Results:

Several synthetic promoters were successfully constructed.
These promoters specifically mediated gene expression in colorectal cancer cells.
The novel method allows for the generation of promoter libraries with increased specificity.

Conclusions:

The developed approach enables the construction of synthetic promoters with high specificity.
This method facilitates the selection of promoters active under predefined gene expression profiles.
The findings offer a new strategy for designing synthetic promoters for targeted gene expression applications.
