Repression of Pax 2 by WT 1 during normal kidney development . ^^^ We have examined the spatial and temporal expression patterns of Pax 2 and the Wilm ' s tumor suppresser protein WT 1 with specific antibodies in developing mouse kidneys . ^^^ A marked increase in WT 1 protein levels coincided precisely with down regulation of the Pax 2 gene in the individual precursor cells of the visceral glomerular epithelium , suggesting a direct effect of the WT 1 repressor protein on Pax 2 regulatory elements . ^^^ To examine whether WT 1 could directly repress Pax 2 transcription , binding of WT 1 to three high affinity sites in the 5 ' untranslated Pax 2 leader sequence was demonstrated by DNAseI footprinting analysis . ^^^ Furthermore , co transfection assays using CAT reporter constructs under the control of Pax 2 regulatory sequences demonstrated WT 1 dependent transcriptional repression . ^^^ |

Differential regulation of the human Wilms tumour suppressor gene ( WT 1 ) promoter by two isoforms of PAX 2 . ^^^ PAX 2 and WT 1 encode transcription factors expressed during fetal kidney development in patterns that overlap both spatially and temporally . ^^^ The overlap of PAX 2 and WT 1 expression in fetal kidney prompted us to determine whether PAX 2 regulates the WT 1 gene . ^^^ To investigate this possibility , the WT 1 promoter and a series of WT 1 promoter deletion fragments were cloned into a luciferase reporter vector , and used in co transfection experiments with PAX 2 expression constructs . ^^^ PAX 2 transactivated the WT 1 promoter up to 35 fold in CHO K 1 cells , and from four to sevenfold in 293 cells . ^^^ |

In the present study , the fate of Wt 1 mutant cells in chimeric kidneys was assessed by in situ marker analysis , and immunocytochemistry was used to re examine the claim that glomerulosclerosis ( GS ) is caused by loss of WT 1 and persistent Pax 2 expression by podocytes . ^^^ The development of GS was preceded by widespread loss of ZO 1 signal in podocytes ( even in kidneys where < 5 % of glomeruli contained Wt 1 mutant podocytes ) , increased intra renal renin expression , and de novo podocyte TGF beta 1 expression , but not podocyte Pax 2 expression or loss of WT 1 , synaptopodin , alpha actinin 4 or nephrin expression . ^^^ However , podocytes in partially sclerotic glomeruli that still expressed WT 1 at high levels showed reduced vimentin expression , cell cycle re entry , and re expressed desmin , cytokeratin and Pax 2 . ^^^ The results suggest that : ( 1 ) GS is not due to loss of WT 1 expression by podocytes ; ( 2 ) podocyte Pax 2 expression reflects re expression rather than persistent expression , and is the consequence of GS ; ( 3 ) GS is mediated systemically and the mechanism involves activation of the renin angiotensin system ; and ( 4 ) podocytes undergo typical maturational changes but subsequently de differentiate and revert to an immature phenotype during disease progression . . ^^^ |

Possible regulation of Wilms ' tumour gene 1 ( WT 1 ) expression by the paired box genes PAX 2 and PAX 8 and by the haematopoietic transcription factor GATA 1 in human acute myeloid leukaemias . ^^^ PAX 2 , PAX 8 and GATA 1 are known physiological regulators of WT 1 . ^^^ In the present study , we analysed either bone marrow or blood samples of 43 AML patients for the expression levels of WT 1 , PAX 2 , PAX 8 and GATA 1 by real time reverse transcription polymerase chain reaction ( LightCycler ) . ^^^ PAX 2 expression was found in 11 of 43 AML samples , with a clear correlation of PAX 2 with WT 1 expression levels observed . ^^^ In conclusion , PAX 2 , and possibly PAX 8 , appears to be a candidate for the upregulation of WT 1 in a proportion of AML , whereas GATA 1 expression can not be explained as an inducer of WT 1 . ^^^ |
