Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Cancer-Critical Genes I: Proto-oncogenes

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Area of Science:

Bioinformatics and Computational Biology
Genomics and Cancer Research

Background:

Discovering novel cancer genes is crucial for understanding cancer and developing targeted therapies.
Bioinformatics approaches can accelerate the identification of potential cancer genes.

Purpose of the Study:

To develop and evaluate a classifier for predicting potential cancer genes by integrating diverse biological evidence.
To compare the performance of different machine learning models in cancer gene prediction.

Main Methods:

Integrated multiple biological evidence: protein-protein interaction network properties, sequence, and functional features.
Detected 55 significant features and selected 14 cancer-associated features for classifier training.
Trained and evaluated four machine learning models: logistic regression, Support Vector Machines (SVM), BayesNet, and decision tree (J48) using 5-fold cross-validation.

Main Results:

Logistic regression achieved the highest prediction power (Area Under the Curve = 0.834), outperforming SVM, BayesNet, and J48 tree.
The integrated prediction model significantly outperformed models based on individual biological evidence.
Network and functional features demonstrated stronger predictive power than sequence features for cancer genes.

Conclusions:

The developed logistic regression classifier, integrating multiple biological features, effectively identifies potential cancer gene candidates.
The integrated approach significantly enhances the accuracy of cancer gene prediction compared to single-feature models.
Network and functional data are key predictors in identifying novel cancer genes.
