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...

Genetic Screens

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...

Quantitative Aspects of Drug-Receptor Interaction

Quantitative Aspects of Drug-Receptor Interaction

The receptor occupancy theory connects a drug's response to the number of occupied receptors. With higher drug concentrations, more receptors are occupied, leading to increased responses. The formation of drug-receptor complexes involves association and dissociation rates, which reach equilibrium when the forward and backward reactions are equal. The equilibrium association constant (Ka) and its inverse, the equilibrium dissociation constant (Kd), indicate drug affinity. Higher Ka and lower Kd...

Area of Science:

Yeast genetics
Systems biology
Bioinformatics

Background:

Synthetic genetic arrays (SGAs) are powerful for high-throughput genetic interaction analysis in yeast.
Previous SGA methods have been extended to quantify changes in genetic interactions across conditions, termed 'differential interactions'.

Purpose of the Study:

To develop a novel, quantitative differential interaction score using statistical information from experimental design.
To improve the analysis of differential genetic interactions and network structures.

Main Methods:

Leveraging statistical information from experimental design to calculate a quantitative differential interaction score.
Comparing the performance of the novel score against existing differential interaction scores.
Exploring the utility of differential genetic similarity in network analysis.

Main Results:

The proposed quantitative differential interaction score demonstrates favorable performance compared to previous methods.
The approach is well-suited for differential network analysis.

Conclusions:

The novel quantitative score enhances the study of differential genetic interactions in yeast.
The method provides a preferred approach for differential network analysis, with an available MATLAB implementation.
