Pax8 and Wnt4 expression in human thyroid cancer cell lines. Wnt4 and Pax8 expression was measured by qRT-PCR in four human thyroid cancer cell lines: WRO from follicular thyroid cancer, Cal62 from anaplastic thyroid carcinoma, FB2 and BCPAP from papillary thyroid carcinoma. RNA from six non-pathological thyroids (N.T.) was used as control. Quantitative real-time PCR was carried out in triplicate as described in Materials and Methods. Glyceraldehyde 3-phosphate dehydrogenase was used as reference gene; results are reported as 2-∆Ct. Data are expressed as the mean ± SD (P < 0,05). The bottom panel shows the total protein extracts of FRTL-5 cells (used as normal thyroid) and human thyroid cancer cells WRO, Cal62, FB2 and BCPAP separated on SDS-PAGE and subjected to Western blot analysis with specific antibodies as indicated in the panel. The hybridization with GAPDH assessed the protein uniform loading integrity. Fold represents the quantification of protein levels normalized with GAPDH.
