We have also targeted Trp53 in cells isolated from a previous transgenic murine fallopian tube carcinoma model15, in which Cre recombinase, under the control of the anti-Mullerian hormone type 2 receptor promoter (Amhr2-Cre), was used to delete Dicer, a key processor of microRNAs, and Pten selectively in the fallopian tube. The gene discussed is TP53; the disease is fallopian tube carcinoma.
