Full textEpidemiological and experimental studies suggest that the progression of Chronic Kidney Disease (CKD) after an initial injury is genetically determined, but the genetic networks that contribute to this predisposition remain unknown. Among the potential molecular pathways involved in CKD, this study focused on the Hippo pathway, an evolutionarily conserved signaling cascade crucial for regulating organ size and cell proliferation. The paralogs proteins YAP and TAZ, two transcriptional coactivators of the Hippo pathway, have recently been identified also as mechanosensors, capable of detecting a wide range of mechanical cues and translating them into cell-specific transcriptional programs. Activation of YAP and TAZ has been implicated to the progression of several kidney diseases and in the transition from acute kidney injury (AKI) to CKD. However, the underlying mechanisms remain unclear and their role under physiological conditions is still not well understood. The aim of this project is to elucidate the role of YAP and TAZ in the renal tubules. First, using the combination of inducing transgenic mouse models and nephrectomy as a model of CKD, we investigated the effect of the selective inactivation of Yap or Taz gene in renal tubular cells in this disease context. Our findings revealed a potential redundancy between these two proteins in tubular epithelial cells. Interestingly, our mice deficient in both YAP and TAZ developed a spontaneous severe renal phenotype with tubular injury, fibrosis and inflammation, which was described in detail in this work. Through transcriptomic analysis, we identified a new novel molecular signature that may provide further insight into the mechanisms regulated by YAP and TAZ in tubular cells. Paradoxically, in our double knock-out model, we observed a worsening of YAP and TAZ expression and activation, in parallel with the lesion progression. This appeared to be the result of an expansion of the "non-recombined" cells, showing the complex roles of YAP and TAZ in the cross-talk with the neighbouring cells. These data demonstrated the essential role of YAP and TAZ in maintaining tubular homeostasis and the intricate balance required for their regulation. This complexity may have implications for therapeutic strategies targeting the inhibition of YAP and TAZ in kidney disease, especially considering the potential side effects that could make such approaches more challenging

Full textHepatocyte Nuclear factor 1 beta (HNF1beta) is a transcription factor expressed in epithelial cells of different organs, such as pancreas, intestine and kidney. The most penetrant phenotypic trait in patients carrying HNF1B mutations is the presence of renal abnormalities, frequently associated with Maturity Onset Diabetes of the Young type 5 (MODY5). During my thesis, I analyzed the role played by this transcription factor in different compartments and at different time points in mouse kidney, using a Cre LoxP strategy. Our laboratory has previously shown that Hnf1b specific inactivation in the epithelial nephron precursors cells (Six2Cre) leads to defective tubular specification and expansion and to the formation of glomerular cysts. The analysis of the morphogenetic processes of glomerulogenesis in the absence of HNF1beta led me to propose a new mechanism of glomerular cyst formation. In mutant nephron, the connection between the glomerulus and the tubular component is abnormally trapped inside the glomerular cup. Due to this unusual configuration, the trapped tubule is surrounded by capillaries and mesangial cells, leading to a constriction of the urinary glomerular outflow. When filtration starts, the production of the primary urine might induce the dilation of the Bowman capsule and the formation of glomerular cyst. In the second part of my thesis, I analyzed the role played by Hnf1b in proliferative versus quiescent tubular cells, by inactivating this gene in renal tubules at different time points (inducible Ksp-CreERT2). My results showed that Hnf1b inactivation during postnatal tubular elongation leads to polycystic kidney disease, as previously described in our laboratory. Analysis of this new inducible model of Hnf1b inactivation also highlighted for the first time a fibrotic phenotype in the tissue surrounding the cysts. The later inactivation in a more quiescent status is characterized by the presence of focal tubulointerstitial fibrosis and tubular dilation. Interestingly, in this context, Hnf1b-deficient proximal tubular cells present a partial loss of epithelial differentiation, characterized by a reduced expression of tubular markers (LTL) and de novo expression of vimentin. At the molecular level, the expression of Zeb2, a transcription factor involved in epithelial to mesenchymal transition, is increased. This is due to the downregulation of its inhibitor miR200, a direct target of HNF1beta. Finally, transcriptomical analyses in postnatal and postweaning periods showed that two major pathways are commonly affected. The development and differentiation of nephrons are severely compromised and pro-inflammatory and fibrotic signaling cascades are strongly upregulated. All together these results improved our knowledge about the role of HNF1beta in glomerulogenesis and adult kidney
