  sub:_5 prov:value "e have made use of the Lmx1b knockout mouse. Transmission electron micrographs showed that glomerular development in general and the differentiation of podocytes in particular were severely impaired. The glomerular capillary network was poorly elaborated, fenestrae in the endothelial cells were largely missing, and the glomerular basement membrane was split. In addition podocytes retained a cuboidal shape and did not form foot processes and slit diaphragms. Expression of the alpha4 chain of collagen IV and of podocin was also severely reduced. Using gel shift assays, we demonstrated that LMX1B bound to two AT-rich sequences in the promoter region of NPHS2, the gene encoding podocin." ;
