From development to cancer: lessons from the kidney to uncover new therapeutic targets

Anticancer Res. 2012 Sep;32(9):3609-17.

Abstract

Several genes play essential roles in human development and alteration of their expression or regulation leads to various pathologies. This review examines the literature on the expression and the roles of neurogenic locus notch homolog protein (NOTCH), sonic Hedgehog (SHH) and wingless-type (WNT) pathways, as well as the nephrogenic transcription factors Wilms' tumor 1 (WT1), paired box 2 (PAX2) and homeobox protein lim-1 (LIM1) in clear cell renal cell carcinoma. Besides being re-expressed in human tumors, the inhibition of these factors has strong antitumor activity both in vitro and in vivo. Interestingly, these pathways are also part of the molecular network involved in the development of organs including nephrogenesis. The identification of developmental pathways involved in clear cell renal cell carcinoma growth places an additional piece into the molecular puzzle of cancer mechanisms. Moreover, the evaluation of these molecules could pave the way to innovative and safe therapies for this refractory disease. Valuable prognostic markers might also be identified through these studies. Finally, the proof of concept in other types of cancer is reviewed.
