 TGF-β0, either alone or in combination, or were left untreated. Then, either nuclear extracts (n.e.) or total cell lysates (t.c.l.) were analysed by westernblot (**A,C**), or RNA samples were analysed by real-time PCR (**B,D**) for the expression of Slug, L0CAM, E-cadherin or vimentin. Lamin-A/C and Hsp00 were used as loading controls for the westernblots of nuclear extracts and total cell lysates, respectively (**A,C**), and for normalization of Slug, L0CAM, E-cadherin and vimentin mRNA level TBP was analysed in parallel (**B,D**). Either a representative result from three independent experiments (**A,C**) or the mean ± SD from six independent experiments (**B,D**) are shown, \*p\<0.00 (+
