NOTCH1 and hydrops fetalis: The effect of testosterone on Notch1/N1ICD expression was partly suppressed by HF in both TM4 (p < 0.01; Figure 4c,f,l) and PSC (p < 0.01; Figure 4e,h,n), whereas Bic completely inhibited testosterone-induced Notch1/N1ICD expression in all cellular models studied (p < 0.001; Figure 4c–h,l–n).
