Alan O. Perantoni, Ph.D.
Senior Investigator
Head, Differentiation and Neoplasia Section

Dr. Perantoni has devoted his efforts to identifying (1) the ligands responsible for renal progenitor/stem cell survival and differentiation, (2) the molecular targets of those ligands, (3) the mechanisms responsible for the dysregulation of normal signaling in Wilms tumor, and (4) the targets of dysregulation in those tumors.

As Chief, he is responsible for a laboratory dedicated to the analysis of major developmental signaling pathways that contribute to cell growth, differentiation, morphogenesis, and cancer.

Areas of Expertise
1) kidney and reproductive tract development 2) renal progenitor signaling 3) STAT transcription factors in development and cancer 4) FGF and WNT signaling in kidney 5) Wilms tumor

Growth/Differentiation Factors in Organogenesis and Their Roles in Tumorigenesis

Morphogenesis in the differentiating metanephros is regulated by reciprocal interactions between ureteric bud (UB) epithelia and the metanephric mesenchyme (MM). The UB invades the overlying MM and induces conversion of the mesenchyme into stromal and epithelial elements, which form the nephron. In turn, the MM stimulates the UB to grow and branch, forming the collecting duct system. The Differentiation and Neoplasia Section focuses on the elucidation of mechanisms of inductive signaling in metanephric development, seeking (1) the ligands responsible for renal progenitor survival and nephronic differentiation, (2) other non-inductive regulatory factors of nephrogenesis, (3) the molecular targets of induction, (4) dysregulation of normal inductive signaling during development of pediatric neoplasms such as the Wilms tumor or congenital mesoblastic nephroma, and (5) targeting the dysregulated signaling in these tumors. The Section uses both explants of metanephric rudiments and mouse genetic models in these studies. We also have ongoing efforts to map the genetic locus responsible for sensitivity to nephroblastoma (Wilms) induction in rats. We expect that as we decipher the roles of various inductive signaling mechanisms in development and understand their dysregulation in tumorigenesis, our studies will lead to novel animal models and targeting agents for drug development.
