Gene-Protein-metabolism links Cell Metabolism Assays for OMICS Research
STANDARD Parameters of Functional METABOLIsm Genomics Cells use gene expression to synthesize proteins and other products that are essential for various cellular functions. Gene expression levels, while associated with metabolism, cannot solely predict the functional impact on metabolism. This creates a gap in understanding the complex physiological relation between genes and metabolism. Researchers are using XF Technology to link functional metabolism to gene expression for a complete picture. The XF Cell Mito Stress Test measures the key parameters of mitochondrial respiration: basal respiration, ATP-linked respiration, maximal respiration, and spare respiratory capacity. The XF Glycolysis Stress Test measures the key parameters of glycolytic activity: glycolysis, glycolytic capacity, glycolytic reserve.

Proteomics Advances in proteomic technology enables genome-wide data analysis, pinpointing specific proteins and expression levels. Proteomic data directly links to metabolism without requiring the regulatory mechanisms associated with mrna expression and final protein expression. However, conclusions utilizing only these types of experiments are limited. XF Technology not only confirms proteomic data but also allows for further investigation of protein function.

However, the data from these techniques alone are not sufficient to assess functionality within a biological context. XF Technology provides real-time analysis of cellular response to stress or nutrients, and can direct metabolomics research, adding efficiency and direction to any area of research.

Functional metabolic assays The Genotype-Phenotype Link The traditional paradigm encompassing the flow of information from gene to protein to function can be found in nearly every biology and biochemistry textbook. At the time, this discovery was thought to explain all of biology, health, and disease. However, only focusing on the expression of a single gene or protein neglects the multi-faceted consequences of that expression on metabolism, as well as overall cell and tissue health. Mitochondria are at the crux of cellular energy generation, intracellular signaling, and cell death and survival regulation. Compromised mitochondria can strain the expansive and intricate cellular metabolic network. There is increasing appreciation for the role of mitochondria in disease pathology, etiology, and cell health. Gene Expression Integrating processes that demonstrate the link amongst genes, proteins, and metabolism allows researchers to analytically answer their scientific questions. XF Technology provides researchers the necessary tools to measure the functional, metabolic impact of gene and protein expression, faster and easier using live cells.
