High throughput gene expression profiling: a molecular approach to integrative physiology.

Area of Science:

• Integrative physiology
• Molecular biology
• Genomics

Background:

• Integrative physiology seeks to understand complex interactions within organisms.
• DNA microarray technology offers high-throughput gene expression profiling.
• Physiology has been slow to adopt these molecular techniques due to data and analysis challenges.

Purpose of the Study:

• To propose a concept of multidimensional integration in physiology.
• To highlight the role of DNA microarrays and other 'omics' approaches.
• To achieve a comprehensive understanding of physiological functions.

Main Methods:

• Utilizing DNA microarray technology for gene expression profiling.
• Integrating data from functional genomics and proteomics.
• Analyzing studies in simpler and mammalian model organisms.

Main Results:

• DNA microarrays are powerful tools for integrative physiology.
• Multidimensional integration is feasible and enhances understanding.
• Question-driven profiling complements traditional hypothesis-driven research.

Conclusions:

• Advances in technology and analysis enable multidimensional integration.
• Integrative physiologists can leverage these techniques for complex functions.
• DNA microarrays are essential for modern integrative physiology research.
