Study Notes
Key Concepts in Gene Expression Analysis
- Trivial ratio differences may not be significant due to variation, despite large values.
- P-value of 0.05% results in 5% false positives in all tests, leading to significant but non-existent differences.
- False Discovery Rate (FDR) is used for multiple testing in gene expression, giving the probability of false positives among significant differences.
- Bonferroni method is stringent and may miss true positives in gene expression analysis.
- Clustering heat maps visualize gene expression profiles and sample similarities, aiding in identifying regulatory networks or pathways.
- Successful gene expression analysis involves understanding phenotypic effects, protein families, physical properties, and gene ontology.
- Gene expression is dynamic and affected by lifestyle; positive changes can be achieved through learning, exercise, diet, fasting, and specific breathing techniques.
- Gene ontology categorizes gene functions into cellular component, biological process, and molecular function, providing insight into biological systems and pathways.
- Enrichment analysis using gene ontology helps understand the pathways/processes affecting a phenotype.
- Protein structure changes, such as amino acid substitutions, can have dramatic effects, leading to diseases like cystic fibrosis and sickle cell disease.
- Protein analysis involves determining secondary and tertiary structures using algorithms, prediction, and databases like the Protein Data Bank.
- Transcription factors like Spi1 and C/EBP, and cytokines like IL-1B, play critical roles in gene regulation and inflammatory responses.
