Cytokeratin 15 marks basal epithelia in developing ureters and is upregulated in a subset of urothelial transitional cell carcinomas

ABSTRACT: The mammalian ureter contains a water-tight epithelium surrounded by smooth muscle. Key molecules have been defined which regulate ureteric bud initiation and drive the differentiation of ureteric mesenchyme into peristaltic smooth muscle. Less is known about mechanisms underlying the developmental patterning of the multilayered epithelium characterising the mature ureter. In skin, which also contains a multilayered epithelium, cytokeratin 15 (CK15), an intermediate filament protein, is a marker for cells whose progeny contribute to epidermal regeneration following wounding. Moreover, CK15+ precursor cells in skin can give rise to basal cell carcinomas. In the current study, using transcriptome microarrays of embryonic wild type mouse ureters, we detected Krt15, coding for CK15.

RNA-SEQ analysis of various developing and adult kidney components.

Project description:We used micro-dissection techniques and/or FACS to isolate cell types from the developing and adult kidney (E11.5 ureteric buds, E12.5, P1 and P4 cap mesenchyme, E15.5 collecting ducts, proximal tubules, ureter, Adult renal proximal tubules, podocytes, endothelial and mesangial cells). RNA-SEQ analysis was performed to determine the transcriptional profile of each cell type, identify component specific transcripts and isoforms and cell-type specific long-noncoding RNAs. In addition the unbiased nature of RNA-SEQ will potentially identify novel transcripts that have not been annotated in the database. Total RNA is obtained from micro-dissected and/or FACS isolated embryonic and adult kidney components. The long term goal is to generate a transcriptional atlas of developing kidney.

Distal nephron plasticity allows the induction of ureteric tip and stalk for the modelling of collecting duct disease

Project description:During development, distinct progenitors contribute to the nephrons versus the ureteric epithelium of the kidney. Indeed, previous pluripotent stem cell-derived models of kidney tissue either contain nephrons or pattern specifically to the ureteric epithelium. By reanalysing the transcriptional distinction between distal nephron and ureteric epithelium in human fetal kidney, we show here that while existing nephron-containing kidney organoids contain distal nephron epithelium and no ureteric epithelium, this distal nephron segment alone displays significant in vitro plasticity and can adopt a ureteric epithelial tip identity when isolated and cultured in defined conditions. “Induced” ureteric epithelium cultures can be cryopreserved, serially passaged without loss of identity and transitioned towards a collecting duct fate. Indeed, cultures harbouring loss-of-function mutations in PKHD1 recapitulate the cystic phenotype associated with autosomal recessive polycystic kidney disease.

Fat transcriptome patterns associated with heterogeneous metabolic, hormonal and behavioral adaptation to high fat diet feeding in mice

Project description:The effect of high fat diet feeding on adipose tissue gene transcription regulation was investigated in C57Bl/6J mice using Affymetrix gene expression arrays. Expression profiling was determined in 5 months old male mice showing heterogeneous metabolic, hormonal and behavioral adaptation to high fat diet (40% fat) feeding for 15 weeks. Control mice were fed a standard carbohydrate chow. Six animals per group were used.
