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,...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Epistasis Analysis

Epistasis Analysis

Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Genome-wide Association Studies-GWAS

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...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Background:

Infectious diseases present significant global health challenges.
Genome-Wide Association Studies (GWAS) are crucial for identifying genetic susceptibility to diseases.
Detecting high-order gene interactions (epistasis) is vital for understanding complex disease genetics, but current methods face computational and privacy challenges.

Purpose of the Study:

To develop a secure and efficient algorithm for detecting high-order gene interactions.
To address limitations of existing methods, including low detection power, high computational cost, and privacy vulnerabilities.
To enhance the accuracy of identifying susceptibility genes for infectious diseases.

Main Methods:

Proposed a safe harmony search algorithm (HS-DP) integrating five objective functions (K2-Score, JS divergence, logistic regression, mutual information, Gini) using linear weighting.
Incorporated Differential Privacy (DP) theory through a function disturbance mechanism to protect individual genetic information.
Validated the algorithm's performance and superiority through experimental analysis.

Main Results:

The HS-DP algorithm effectively screens high-order Single Nucleotide Polymorphism (SNP) sets with high correlation.
The differential privacy mechanism provides theoretical and practical guarantees for individual privacy protection.
Experimental results demonstrate improved detection accuracy compared to existing methods.

Conclusions:

HS-DP offers a robust solution for high-order gene interaction detection in GWAS.
The algorithm successfully balances high detection power with strong privacy preservation.
This approach facilitates more accurate and secure identification of genetic factors in infectious diseases.
