Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

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...
Combinatorial Gene Control02:33

Combinatorial Gene Control

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...
Genetic Screens02:46

Genetic Screens

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 result in visible changes...

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • Identifying cancer driver genes is crucial for understanding oncogenesis and advancing precision medicine.
  • Current methods often overlook non-coding driver genes by focusing on homogeneous networks and single-omics data.

Purpose of the Study:

  • To develop a novel framework, GMHAN, for identifying both coding and non-coding cancer driver genes.
  • To improve the accuracy and comprehensiveness of cancer driver gene identification by integrating multi-omics data and network topology.

Main Methods:

  • Integrated three types of omics data and protein-protein interaction (PPI) network topology.
  • Utilized heterogeneous graph attention networks (HAN) for deep feature embedding of genes and miRNAs.
  • Employed a multilayer perceptron to predict the probability of genes and miRNAs being cancer drivers.

Main Results:

  • GMHAN demonstrated superior performance compared to seven existing methods on pan-cancer and cancer-specific datasets.
  • Achieved higher Area Under the Curve (AUC) and Area Under the Precision-Recall Curve (AUPR) scores.
  • Effectively identified carcinogenic drivers, including non-coding genes.

Conclusions:

  • GMHAN provides a powerful and effective framework for identifying cancer driver genes.
  • The integration of multi-omics data and network features enhances the accuracy of driver gene discovery.
  • This approach holds promise for advancing precision medicine by uncovering novel therapeutic targets.
