Genome-wide Association Studies-GWAS

12.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Genetic Screens

4.8K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Combinatorial Gene Control

8.2K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Area of Science:

  • Molecular Biology
  • Bioinformatics

Background:

  • Codon optimization is crucial for heterologous protein expression due to species-specific codon bias.
  • Existing codon optimization tools may produce sequences with suboptimal local guanine-cytosine (GC) content.
  • Poor GC content distribution hinders primer design for gene subcloning and whole gene synthesis via polymerase chain reaction (PCR).

Purpose of the Study:

  • To develop a user-friendly software tool for manual adjustment of GC content in optimized gene sequences.
  • To facilitate improved primer design and gene synthesis experiments.

Main Methods:

  • A stand-alone software application was developed using Python.
  • The software features a Graphical User Interface (GUI) for intuitive codon manipulation.
  • It defaults to *Escherichia coli* codon frequency but supports other species.

Main Results:

  • The software enables users to visualize and modify local GC content in real-time.
  • It allows for manual adjustment of codons to achieve desired GC profiles.
  • Facilitates more efficient gene subcloning and PCR-based gene synthesis.

Conclusions:

  • The developed software offers a convenient solution for fine-tuning gene GC content.
  • It addresses limitations of existing tools by providing manual control over GC distribution.
  • Enhances the success rate of subsequent gene cloning and synthesis experiments.
