We begin with four different modular networks within and
between which nodes (in this case, genes, mRNA, proteins, biochemical or physiological properties, or environmental factors) interact to yield the ultimate
phenotype.
If interactions
between IL - 15 and IL - 15Rα were to occur strictly as a secreted cytokine binding to a cell surface receptor, then similar exercise and muscle
phenotypes would have been observed in both IL - 15Rα — KO mice and IL - 15 — KO mice, since ligand - receptor binding would have been interrupted in both of these mouse strains.
More patients are needed to clarify the possible correlation
between the location of the mutation and disease severity, but understanding this relationship could be of great value in identifying molecules directly involved in clinical
phenotypes and in providing new targets for drug discovery,» says Dr. Tohyama.
