In first place, I would like to thank the members of the jury that have kindly accepted to evaluate my work: Pr. Knebelmann, Pr Waltz, Pr Knebelman, Pr Salomon. A special thank goes to Mme Lelongt and M Cohen-Tannoudji to have reviewed my thesis and to give very useful suggestions in order to ameliorate it. A long journey needs good leading. For the precious and irreplaceable help and support I would like to thank Marco and Evelyne that overviewed all my work (and corrected the not- so-few mistakes I did on the way). They avoid me to get lost in failing experiments and frustrating periods, as well as to encourage my enthusiasm. I’m still in love with the research! Once the journey has started, I found a very important help from the entire group of colleagues: the “Pontoglio’s team” crew always supported me and offered me the pratical/technical/moral support to achieve my work. I would like to thank the actual members of the lab (Serge, Michel, Magali, Jon, Cecile and Claire) and the people I have the pleasure to meet in the lab and that are now in the different corner of the world (the spanish Miguel and Kiko, Celine and Tristan). A big thank to all the friends that I meet during my thesis: too many to number them without forgiving someone… Thanks for the support you gave me, for the antibodies protocols and suggestion you gave me, without forgetting the long nights spent partying around! In conclusion, useless to check the list of the names, I could not double the size of my thesis!! But I will remember all of you wherever I will go Of course, a very special thank goes to my parents Ezio and Grazia that supported me (even with excellent food supplies) all along my thesis and to my brothers Corrado and Emanuele! Thanks also to Giulia and Veronica to support and stand my bros, and without forgetting the newcomer Edoardo. Finally, THE very special thanks to Eva that stand me all along the way and gave me the strength to keep going on, even if sometimes the things seem not to work and I was tempted to give up.

The structure of the pronephros and development of mesonephric kidney in Russian sturgeon larvae, Acipenser gueldenstaedtii Brandt at different stages of early postembryonic development (from hatching to 14 days), were studied with histological and electronic microscopy methods. The larval pronephros is represented by the system of bilaterally located pronephric tubules with ciliated nephrostomes and funnels and exog- enous single glomus, which is not integrated directly into pronephric tubules and located in the pronephric chamber. The glomus is positioned below the dorsal aorta and vascular- ized by its capillaries. The glomus has the same features of the thin structure that are typical of and necessary for the function of a filtering organ. The structure of the prone- phros in acipenserids is discussed and compared with teleosts and amphibians. Histogen- esis of the mesonephric kidney is observed during the period of pronephros functioning; it is complete by the time the larvae transfer to exogenous feeding. At this moment, the pronephros undergoes significant structural degradation.

Heterozygous mutations in human HNF1B cause the complex multisystem syndrome known as Renal Cysts And Diabetes (RCAD). The most prominent clinical features of this autosomal dominant disorder are non-diabetic renal disease resulting from abnormal renal development and diabetes mellitus (reviewed by Clissold RL et al., 2015). During early mouse kidney development, Hnf1b has been shown to be required for ureteric bud branching and initiation of nephrogenesis (Lokmane et al., 2010). Hnf1b conditional inactivation in murine nephron progenitors has revealed an additional role in segment fate Xenopus is a well established and attractive model to study kidney development (Krneta-Stankic V. et al, 2017). Renal function at larval stages relies on two pronephroi located on both sides of the body, each consisting on one giant nephron displaying the same structural and functional organisation than the mammalian nephron. Moreover, pronephric and metanephric differentiation and morphogenesis share most of the signalling cascades and gene regulatory networks.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Several molecular targeting agents have failed to treat ovarian CCC. Recent reports have identified metabolic alterations through HNF1B, which is highly expressed in ovarian CCC. The Warburg effect, GSH synthesis, and mitochondrial regulation occur in CCC. The metabolic behaviors of ovarian CCC resemble the evolution of life to survive in stressful environments. Understanding the fundamental biology of ovarian CCC might help in the development of novel therapeutic strategies.

MAMMALIAN KIDNEY DEVELOPMENT The filtration function of the kidneys is accomplished by basic units called nephrons (Fig. 1.1). Humans on average have 1 million nephrons per adult kidney but the range of ANATOMIC OVERVIEW OF THE 4 MAMMALIAN KIDNEY total nephrons is highly variable across human populations. Each mouse kidney may contain up to 12,000–16,000 nephrons The kidney is a sophisticated, highly vascularized organ that depending on the strain.5 This wide range in nephron number plays a central role in overall body homeostasis.
