Inhibition of prolyl hydroxylase promotes the reprogramming of Sox9+ renal progenitor cells and renal regeneration

Project description:Mammalian kidney has very limited ability to repair or regenerate after acute kidney injury (AKI). The maladaptive repair of AKI promotes the progression to chronic kidney disease (CKD). Therefore, it is extremely urgent to explore new strategies to promote the repair/regeneration of injured renal tubules after AKI. It has been shown that hypoxia induces heart regeneration in adult mice. However, it is unknown whether hypoxia can induce kidney regeneration after AKI. In this study, we used a prolyl hydroxylase domain inhibitor (PHDI), MK-8617, to mimic hypoxia condition and found that MK-8617 significantly ameliorates ischemia reperfusion injury (IRI) induced acute kidney injury. We then showed that MK-8617 dramatically facilitates renal regeneration via promoting the proliferation of injured renal proximal tubular cells (RPTCs) after IRI-induced AKI. We then performed bulk mRNA sequencing and discovered that multiple nephrogenesis- related genes were significantly upregulated with MK-8617 pretreatment. Furthermore, we showed that MK-8617 may alleviate proximal tubule injury via stabilizing HIF-1α protein specifically in renal proximal tubular cells. We also demonstrated that MK-8617 promotes the reprogramming of renal proximal tubular cells to Sox9+ renal progenitor cells, and the regeneration of renal proximal tubules. In summary, we discovered that inhibition of prolyl hydroxylase improves renal proximal tubule regeneration after IRI-induced AKI via promoting the reprogramming of renal proximal tubular cells to Sox9+ renal progenitor cells.

Integration of Epigenetic and Transcriptomic Signature reveals Key Transcription Factors involving in Renal Tubular Response to extracellular Stimuli

Project description:To understand the transcription regulation of renal tubular epithelial cells under stimuli, here we investigated transcriptome, chromatin accessibility and their dynamics through RNA-seq and ATAC-seq under the three types of treatments. We identified genome-wide functional regions which coordinated transcription regulation in human renal proximal tubule epithelial cells (HK2). Our results provide a cell type-specific landscape of chromatin dynamics under stimuli and discovered an important TF in renal tubular epithelial cells that mediated genomic response to different injury stimuli.

Peroxisomes are dispensable for normal renal function.

Project description:Peroxisomes are highly abundant in proximal tubules where peroxisomal enzymes have been proposed to play an important role in a variety of metabolic and antioxidant functions. This hypothesis was supported by human genetic studies that identified mutations leading to peroxisomal biogenesis deficiency, resulting in severe multi-organ damage (Zellweger’s spectrum disorders (ZSD)), including renal impairment. However, the role of proximal tubule peroxisomes in renal (patho)physiology remains uninvestigated. We addressed this question in mice with conditional ablation of peroxisomal biogenesis in the renal tubule. Our results demonstrate that renal tubular peroxisomes are dispensable for normal renal function and suggest that renal damage in ZSD patients is of extrarenal origin.

miRNA profiles of tubular cells (Rodent A and Rodent B)

Project description:MicroRNAs (miRNAs) are endogenous small RNAs of 18–23 nucleotides that regulate gene expression. Recently, plasma miRNAs have been investigated as biomarkers for various diseases. In the present study, we assessed whether the miRNA expression profiles of tubular tissues could discriminate proximal tubule injury and diagnose acute kidney injury (AKI) and the renal tubular dysfunction without morphological changes.

Generation of nephronal cells from human pluripotent stem cells via renal-vesicle formation

Project description:Human pluripotent stem cells (hPSC) provide a possible source for generation of kidney cells and organoids applicable in regenerative medicine, disease modeling and drug screening. By analyzing the effect of different factors on renal differentiation, we established an 8-day-protocol that steered hPSCs to the renal lineage by a step-wise process, segmented into mesoderm induction, intermediate mesoderm specification and metanephric induction outlining renal organogenesis. The differentiated cells contain populations of SIX2+/CITED1+ metanephric mesenchyme- (MM) and of HOXB7+/GRHL2+ ureteric bud (UB)-like cells at the end of 6 days. Transcriptome analysis corroborated that the in vitro generated precursor cell types at day 8 resemble their renal vesicle counterparts in vivo. The cells were further differentiated in 2-dimensional culture into podocyte- and diverse tubular epithelial-like cell types, showing their nephrogenic potential. In 3-dimensional culture, the progenitors gave rise to renal vesicles, and upon mouse embryonic kidney re-aggregation they form tubular structures.

APOL1 renal-risk variants induce mitochondrial dysfunction (Affymetrix 2)

Project description:To assess differential gene expression by APOL1 renal-risk (2 risk alleles) vs. non-risk (G0G0) genotypes in primary proximal tubule cells (PTCs), global gene expression (mRNA) levels were examined on Affymetrix HTA 2.0 arrays in primary PTCs cultured from non-diseased kidney in African Americans without CKD who underwent nephrectomy for localized renal cell carcinoma. To detect differentially expressed gene profiles attributable to APOL1 renal-risk genotypes, African American primary proximal tubule cells with two APOL1 renal-risk alleles (N=5) and lacking renal-risk alleles (N=25) were included in comparisons of global gene expression.
