Project description:Bronchopulmonary dysplasia (BPD) is the most common chronic respiratory disease in premature infants. Recent studies have highlighted the contribution of genetic factors to BPD susceptibility. Our aim was to identify the genetic variants associated to BPD, through a genomewide association study. Two discovery series were performed, using a DNA pooling-based strategy in Caucasian and black African neonates.

Project description:Gender has strong impact on kidney performance. Female gender tends to be renal protective. PKD/Mhm is rat model for human polycystic kidney disease (PKD) caused by a mutation in gene Anks6. PKD progresses faster in male rats compared with females. We used microarrays to detect gender-dependent gene expression in kidney of 36d old PKD/Mhm rats. Experiment Overall Design: Gender-dependent gene expression was examined both in heterozygous PKD/Mhm rats affected with PKD and in their wild type littermates. Three microarrays were hybridized for each combination of gender and genotype.

Project description:Paroxysmal kinesigenic dyskinesia (PKD) is an episodic movement disorder with autosomal-dominant inheritance and marked variability in clinical manifestations.Proline-rich transmembrane protein 2 (PRRT2) has been identified as a causative gene of PKD, but the molecular mechanism underlying the pathogenesis of PKD still remains a mystery. The phenotypes and transcriptional patterns of the PKD disease need further clarification. Here, we report the generation and neural differentiation of iPSC lines from two familial PKD patients with c.487C>T (p. Gln163X) and c.573dupT (p. Gly192Trpfs*8) PRRT2 mutations, respectively. Notably, an extremely lower efficiency in neural conversion from PKD-iPSCs than control-iPSCs is observed by using the iPSC-neural differentiation protocol that relies on the dual inhibition of SMAD signaling. Moreover, we show the high expression level of PRRT2 throughout the human brain and the expression pattern of PRRT2 in other human tissues for the first time. To gain molecular insight into the development of the disease, we conduct global gene expression profiling of PKD cells at four different stages of neural induction and identify altered gene expression patterns, which peculiarly reflect dysregulated neural transcriptome signatures and a differentiation tendency to mesodermal development, in comparison to control-iPSCs. Additionally, functional and signaling pathway analyses indicate significantly different cell fate determination between PKD-iPSCs and controls-iPSCs. Together, the establishment of PKD-specific in vitro models and the illustration of transcriptome features in PKD cells would certainly help us with better understanding of the defects in neural conversion as well as further investigations in the pathogenesis of the PKD disease.

Project description:To explore potential role of SETD2 in PKD-ccRCC transition in vivo, we generated a PKD mouse model by overexpressing oncogene c-MYC under the control of the Ksp promoter (KM mice), and knockout Setd2 gene using the same Ksp promoter in this PKD mice (KMs mice) to establish a ccRCC mouse model. To further characterize biological responses trigered by SETD2 deletion during PKD-ccRCC transition at the mRNA level, we next conducted global transcriptomics studies.

Project description:Current renal organoid models derived from embryonic or induced pluripotent stem cells mimic development. Yet, few studies have attempted to generate organoids from human adult kidney to recapitulate regeneration or pathological dysregulation in vitro. Here, we report a novel expanding regenerative organoids culture system from renal cortex and medulla. Transcriptomic sequencing and immunostaining identified that these organoids share similar molecular features with kidney injury-responsive regeneration. Heterogeneous populations in organoids including cycling epithelial progenitors and differentiated cell types were identified by single cell sequencing including proximal tubules, principal cells and collecting duct (CD) progenitors that can be induced into functional CD system. Furthermore, we established polycystic organoids derived from patients that represent an advanced platform for polycystic kidney disease (PKD) modeling. By drug screening, QNZ, GSK2193874 and AMPK activators were shown to significantly reduce polycystic growth. Our results demonstrated a novel in vitro renal organoid model to study regenerating adult renal cells and PKD mechanism, providing tools for discovery of therapeutic targets.

Project description:Patients with polycystic kidney disease (PKD) encounter a high risk of clear cell renal cell carcinoma (ccRCC), a malignant tumor with dysregulated lipid metabolism. SET domain–containing 2 (SETD2) has been identified as an important tumor suppressor gene in ccRCC. However, the role of SETD2 in tumorigenesis during the transition from PKD to ccRCC remains largely unexplored. Herein, we performed metabolomics, lipidomics, transcriptomics and proteomics with SETD2 loss induced PKD-ccRCC transition mouse model. To characterize biological responses triggered by SETD2 deletion during PKD-ccRCC transition at the protein level, we conducted global proteomics studies.
