Differential expression analysis is a statistical method used to identify changes in gene expression levels between different conditions or groups, often used in genomics to understand disease mechanisms or treatment effects. It involves comparing the expression levels of genes across samples to determine which genes are upregulated or downregulated in response to a specific condition.

Differential expression analysis

Statistical methods are a collection of mathematical techniques used to analyze and interpret data, helping to make informed decisions based on empirical evidence. They encompass a range of procedures, including data collection, analysis, interpretation, and presentation, enabling researchers to draw valid conclusions and predictions from data samples.

Genomics is the study of the entirety of an organism's genes, known as its genome, and how these genes interact with each other and the environment. This field has revolutionized medicine, agriculture, and biological research by enabling a deeper understanding of genetic contributions to health, disease, and evolution.

Disease mechanisms refer to the biological processes and interactions that lead to the development and progression of diseases. Understanding these mechanisms is crucial for identifying potential therapeutic targets and developing effective treatments.

disease mechanisms

Treatment effects refer to the causal impact of a specific intervention or policy on an outcome of interest, distinguishing between the observed outcome and what would have occurred in the absence of the treatment. Understanding these effects is crucial for evaluating the effectiveness of interventions, requiring careful consideration of counterfactual scenarios and potential biases.
