Epistasis Analysis01:09

Epistasis Analysis

5.6K
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...

Evolutionary Relationships through Genome Comparisons

6.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Background and Environment Affect Phenotype

7.3K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Genetic Screens

5.5K
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...

Area of Science:

  • Evolutionary biology
  • Cancer research
  • Computational biology

Background:

  • Cancers evolve dynamically, complicating personalized medicine and treatment predictions.
  • Tumor resistance to therapies is a major clinical challenge, often not predictable from genomic data alone.
  • The genotype-phenotype (GP) mapping, linking genetic makeup to observable traits, is crucial but complex in cancer.

Purpose of the Study:

  • To review and compare models of the genotype-phenotype (GP) mapping in cancer evolution.
  • To provide a generalized evolutionary framework for understanding cancer's dynamic nature.
  • To identify understudied areas for future research in cancer evolution and treatment resistance.

Main Methods:

  • Review of existing models describing the genotype-phenotype (GP) mapping.
  • Analysis within a generalized evolutionary framework considering genotype, phenotype, environment, and fitness.
  • Comparison of different modeling approaches and their conserved evolutionary results.

Main Results:

  • Evolutionary results are often conserved across diverse modeling systems for the GP mapping.
  • The GP mapping is neither injective nor functional, making resistance prediction difficult.
  • Identified understudied areas include phenotypic plasticity and bet-hedging in cancer evolution.

Conclusions:

  • Understanding the genotype-phenotype (GP) mapping is essential for predicting cancer evolution and treatment response.
  • A generalized evolutionary framework aids in analyzing cancer's dynamic behavior.
  • Future research on plasticity and bet-hedging is needed to improve personalized cancer therapies.
