In addition, TSC tumors from 75 week-old male SJL.AMH-SV40Tag mice also expressed anti-Müllerian hormone (AMH; Fig. 4d), a protein traditionally associated with Sertoli cell tumors that would ordinarily develop within the seminiferous tubules and not in the interstitial space where Leydig cell tumors develop [18]. The gene discussed is AMH; the disease is Leydig cell tumor.
