(A) Viability curves of A2780 cell lines transfected with <t>pCMV6</t> (S-Ø and R-Ø) and with the overexpression vector (R-ITF2). Each experimental group was exposed to six different CDDP concentrations for 48h. Data were normalized to each untreated control, set to 100%. The data represent the mean ± SD of at least three independent experiments performed in quadruplicate at each drug concentration for each cell line analyzed. (B) Viability of A2780 cell lines transfected with pCMV6 (R-Ø) and with the overexpression vectors (R-ITF2). (C) Relative expression levels of ITF2 measured by quantitative RT-PCR, represented in Log10 scale; In each experimental group, the sensitive cell line transfected with pCMV6 plasmid was used as a calibrator. Each bar represents the combined relative expression of two independent experiments measured in triplicate. (D) β-catenin transcriptional activity was measured in A2780 cells after ITF2 overexpression and treatment with LiCl (10mM) for 24 hours, transfecting with Super8xTopFlash (Top) or Super8xFopFlash (Fop). The results show the fold induction of the Top/Fop ratio with respect to untreated cells (=1). Values represent the mean of three independent experiments measured by triplicate ± SD.

MIN6 cells were plated at 5 × 10 5 cells per well in 6-well plates and exposed to a TCF7L2-specific short hairpin RNA (shTCF7L2) or a scrambled shRNA (shScr) for 72 h, then cultured for 24 h in the presence of 100 nM E 2 or 1 μM P 4 . ( A ) Western blots showing the TCF7L2 protein content after E 2 or P 4 treatment. ( B ) Viable cells. ( C,D ) Basal and stimulated insulin/proinsulin secretions (normalized to viable cell numbers). ( E,F ) Stimulatory indexes. ( G ) Proinsulin-to-insulin ratio. * P < 0.05 vs. sex hormone treatment control; # P < 0.05 shTCF7L2 vs. shScr.
