Induction of p21 by the Wilms' tumor suppressor gene WT1.

|
We have recently shown that inducible expression of WT1 in osteosarcoma cells triggers programmed cell death, an effect that is associated with transcriptional repression of the endogenous epidermal growth factor receptor.

|
We now show that WT1-mediated apoptosis is preceded by induction of the cyclin-dependent kinase inhibitor p21, associated with G1 phase arrest.

|
This effect is only demonstrated by WT1 isoforms with an intact DNA binding domain, and it is associated with increased expression of endogenous p21 mRNA.

|
WT1-mediated induction of p21 is independent of p53, another tumor suppressor gene known to regulate p21 expression.

|
In the kidney, p21 is expressed in differentiating glomerular podocytes along with WT1.
|

|
We conclude that induction of p21 expression may contribute to WT1-dependent differentiation pathways in the kidney and potentially to the function of WT1 as a tumor suppressor gene.
