  • We demonstrated previously that rat tyrosine phosphatase r-PTPeta expression was suppressed in rat and human thyroid neoplastic cells, and that restoration of r-PTPeta expression reverted the malignant phenotype. To investigate the potential of this gene for cancer therapy, we generated an adenovirus carrying the r-PTPeta cDNA (Ad-r-PTPeta). This virus infected human thyroid carcinoma cells and overexpressed the r-PTPeta protein. Overexpression of r-PTPeta significantly inhibited the growth of four thyroid carcinoma cell lines. Cell growth inhibition was associated with down-regulation of extracellular signal-regulated kinase 1/2 activity, with increased levels of the cell-cycle inhibitor p27(kip1) protein and with dephosphorylation of PLCgamma1, a substrate of DEP-1, the human homologue of r-PTPeta. Finally, the growth of xenograft tumors induced in athymic mice by anaplastic thyroid carcinoma ARO cells transduced with the Ad-r-PTPeta virus was drastically reduced. These data suggest that gene therapy based on restoration of PTPeta function has potential in the treatment of human thyroid malignant neoplasias. (literal)

Abstract
  • We demonstrated previously that rat tyrosine phosphatase r-PTPeta expression was suppressed in rat and human thyroid neoplastic cells, and that restoration of r-PTPeta expression reverted the malignant phenotype.

This virus infected human thyroid carcinoma cells and overexpressed the r-PTPeta protein. Overexpression of r-PTPeta significantly inhibited the growth of four thyroid carcinoma cell lines. Cell growth inhibition was associated with down-regulation of extracellular signal-regulated kinase 1/2 activity, with increased levels of the cell-cycle inhibitor p27(kip1) protein and with dephosphorylation of PLCgamma1, a substrate of DEP-1, the human homologue of r-PTPeta.
