    Abstract
    The human pancreatic cancer cell line T3M4, is known to produce transforming growth factor-alpha (TGF-alpha); as well as overexpress the receptor for this ligand, epidermal growth factor (EGF) receptor. TGF-alpha messenger RNA (mRNA) levels were assayed using northern blot, after addition of epidermal growth factor or TGF-alpha. The level of TGF-alpha mRNA was found to increase 2-fold at 2 hours and then return to near basal levels at 10 hours, after treatment with either ligand. Both ligands were also equipotent in a 2 hour dose response assay, with half maximal stimulation seen at 1 nM and maximal stimulation reached at 4 nM. Furthermore, there appeared to be a 2-fold increase in TGF-alpha transcription as determined by nuclear runoff experiments. Induction of TGF-alpha mRNA coupled with the overexpression of the EGF receptor, may result in a potent autocrine cycle; which may be found in other cancers.
