They also potently blocked MEK phosphorylation in human thyroid cancer cell lines with either RET/PTC1 (TPC1) or BRAF(V600E) (NPA, ARO, and FRO) mutations.
S1P (sphingosine 1-phosphate) receptor expression and the effects of S1P on migration were studied in one papillary (NPA), two follicular (ML-1, WRO) and two anaplastic (FRO, ARO) thyroid cancer cell lines, as well as in human thyroid cells in primary culture.
To investigate TB10 function and relevance in a model system we used an antisense methodology to suppress TB10 protein synthesis in two human thyroid carcinoma cell lines (NPA and ARO).
We studied several GLUT isoforms expression in thyroid tumor cell lines deriving from anaplastic (ARO, FRO), papillary (NPA), follicular (WRO) and medullary (TT) human thyroid carcinoma.
We also investigated the expression level of SRF and an SRF target gene, c-fos in fresh PTC tissues and thyroid cancer cell lines (NPA, FRO and ARO) by Western blot analyses.
