Western blotting of C2C12 extracts 48h right after infection demonstrated important elevation of fibrogen in Ad-cSTAT3-GFP cultures versus Ad-GFP cultures. In order to identify whether or not fibrinogen was developed right after IL-6 challenging, C2C12 myotubes were exposed to murine recombinant IL-6 for up to 48 h. This resulted into an general boost in fibrinogen, each in the cellular compartment by Western blotting and in the culture medium by ELISA. These experiments show that even within the absence of other cell varieties and tissues, skeletal muscle cells respond to IL-6 and activation of STAT3 by synthesizing acute phase protein RNAs and proteins for secretion. Discussion We sought to mimic the higher serum IL-6, acute phase response and muscle wasting of sufferers with cancer cachexia. We chose C26 adenocarcinoma, which exhibits elevated circulating levels of IL-6 that coincide with muscle wasting. Particular clones of the C26 that do not lead to cachexia coincidently usually do not generate IL-6. Consistent with a causative role in muscle wasting in humans, circulating IL-6 has been reported to be a marker of weight loss in sufferers afflicted by many forms of cancer. The consistency of such muscle wasting across many routes of IL-6 administration, like by direct injection of recombinant IL-6, by transgenesis, by implantation of osmotic pump delivering recombinant IL-6, by injection of IL-6 expressing CHO cells into athymic nude mice, and by transfection of plasmid DNA encoding IL-6, testifies to the potency by which IL-6 causes the cachectic phenotype.
