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 Control02:33

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...

Genome-wide Association Studies-GWAS

12.1K
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...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

23.1K
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...

Reporter Genes02:11

Reporter Genes

11.0K
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:

  • Computational Biology
  • Genomics
  • Bioinformatics

Background:

  • Spatial transcriptomics data offers insights into biological phenomena through gene expression patterns.
  • Spatially correlated genes are key to understanding cell-cell interactions and latent biological variables.
  • Existing methods often struggle to distinguish true biological correlations from those driven by cell type composition.

Purpose of the Study:

  • To introduce InSituCor, a novel toolkit for discovering modules of spatially correlated genes.
  • To differentiate true biological spatial correlations from those explained by cell type distribution.
  • To facilitate both unbiased and knowledge-driven exploration of spatial gene expression patterns.

Main Methods:

  • Development of the InSituCor toolkit for analyzing spatial transcriptomics data.
  • Implementation of algorithms to identify gene correlations not explained by cell type landscape.
  • Support for unbiased, whole-dataset correlation discovery and targeted gene exploration.

Main Results:

  • InSituCor effectively identifies spatially correlated gene modules.
  • The toolkit successfully filters out correlations attributable to cell type arrangements.
  • InSituCor enables focused analysis, including the evaluation of spatial co-regulation for ligand-receptor pairs.

Conclusions:

  • InSituCor provides a powerful approach to uncover meaningful biological signals in spatial transcriptomics.
  • By removing confounding factors, InSituCor enhances the efficiency of biological discovery.
  • The toolkit advances the analysis of spatial gene expression and cell-cell communication.
