Description
Kruppel-like transcription factor 5 (Klf5) is expressed during late embryogenesis in the forming murine bladder urothelium. Targeted disruption of the Klf5flox alleles by the ShhGfpCre transgene resulted in failure of the bladder urothelium to mature accompanied by hydronephrosis, hydroureter, and vesicoureteric reflux in all E18.5 fetuses. The bladder urothelium did not stratify nor did it express terminal differentiation markers characteristic of basal, intermediate, and umbrella cells including keratins 20, 14, and 5, and uroplakins. At E18.5, an ectopic alpha smooth muscle actin positive layer of cells was identified subjacent to the undifferentiated Klf5-deficient urothelium. The effects of Klf5 deficiency were unique to the urothelium since maturation of the epithelium comprising the bladder neck and urethra were unaffected by the lack of KLF5. mRNA microarray analysis of whole E14.5 control and Klf5 deficient bladders identified Ppar-gamma and Grhl3 as putative downstream intermediary transcription factors that regulate urothelial maturation. Transient transfection assays demonstrated that KLF5 regulated expression of the mGrhl3 promoter. These observations show that alterations in maturation of the bladder urothelium alone are sufficient to induce bladder dysfunction leading to prenatal hydronephrosis.

Description
Upstream Binding Factor (UBF) is a unique multi-HMGB-box protein first identified as a co-factor in RNA polymerase I (RPI/PolI) transcription. However, its poor DNA sequence selectivity and its ability to generate nucleosome-like nucleoprotein complexes suggest a more generalized role in chromatin structure. We previously showed that extensive depletion of UBF reduced the number of actively transcribed ribosomal RNA (rRNA) genes, but had little effect on rRNA synthesis rates or cell proliferation, leaving open the question of its requirement for RPI transcription. Using conditional gene deletion in mouse, we now show that UBF is indeed essential for transcription of the rRNA genes.

Description
We have previously shown that Il1a-knockout (KO) mice exhibit rapid (at day 1) and persistent improvements in locomotion associated with reduced lesion volume compared with Il1b-KO mice and C57BL/6 controls after traumatic spinal cord injury (SCI). To investigate the mechanism by which Il1a mediates its detrimental effect, we analyzed the transcriptome of the injured spinal cord of Il1a-KO, Il1b-KO and C57BL/6 mice at 24 hours after SCI using GeneChip microarrays.
