Abstract

The hypothesis we tested was that administering corticotropin-releasing factor receptor agonists preserves muscle mass during cancer that is related to changes in tissue gene expression. cDNA microarrays were used to compare mRNAs from muscle and adipose tissues of non-treated and agonist-treated tumor-bearing rats. In muscle of non-tumor-bearing agonist-treated animals we observed decreased expression of genes associated with fatty acid uptake and esterification. In tumor-bearing animals, CRF2R agonist administration produced decreased mRNA content of the atrogene lipin-1. In white adipose tissue, agonist treatment of non-tumor-bearing animals induced genes typically related to muscle structure and function. The fact that this... (More)

The hypothesis we tested was that administering corticotropin-releasing factor receptor agonists preserves muscle mass during cancer that is related to changes in tissue gene expression. cDNA microarrays were used to compare mRNAs from muscle and adipose tissues of non-treated and agonist-treated tumor-bearing rats. In muscle of non-tumor-bearing agonist-treated animals we observed decreased expression of genes associated with fatty acid uptake and esterification. In tumor-bearing animals, CRF2R agonist administration produced decreased mRNA content of the atrogene lipin-1. In white adipose tissue, agonist treatment of non-tumor-bearing animals induced genes typically related to muscle structure and function. The fact that this treatment decreased expression of atrogenes could have clinical application. In addition, agonist treatment changed the gene pattern of adipose tissue to render it similar to that of skeletal muscle; thus, treatment with this agonist alters the gene pattern to what could be called "muscularization of white adipose tissue."
