The present study provides evidence that H19 recruits CTCF to downregulate the expression of PKD1, thereby promoting vulnerable plaque formation and intraplaque angiogenesis in mice with atherosclerosis.
Restoring these miRs by injection of precursors influenced the reduced size of cysts in Pkd1 conditional knockout mice. miR-192 and -194 may act as potential therapeutic targets to control the expansion and progression of cysts in patients with ADPKD.-Kim, D. Y., Woo, Y. M., Lee, S., Oh, S., Shin, Y., Shin, J.-O., Park, E. Y., Ko, J. Y., Lee, E. J., Bok, J., Yoo, K. H., Park, J. H. Impact of miR-192 and miR-194 on cyst enlargement through EMT in autosomal dominant polycystic kidney disease.
We observed that VEGF/PKD-1 signaling axis significantly stimulated the expression of arteriogenic genes and promoted EC proliferation, along with downregulation of CD36 expression.
We also found that tubacin reduced cyst growth by inhibiting proliferation of cyst-lining epithelial cells, downregulated cyclic AMP levels, and improved renal function in a Pkd1-conditional mouse model of ADPKD.
Lysophosphatidic acid/PKD-1 signaling leads to nuclear accumulation of histone deacetylase 7, where it interacts with forkhead box protein O1 to suppress endothelial CD36 transcription and mediates silencing of antiangiogenic switch, resulting in proangiogenic and proarteriogenic reprogramming.
Few patients have been reported carrying, in addition to the familial mutation, variation(s) in polycystic kidney disease 1 (PKD1) or HNF1 homeobox B (HNF1B), inherited from the unaffected parent, or biallelic polycystic kidney and hepatic disease 1 (PKHD1) mutations.
A mouse tumor angiogenesis model revealed enhanced PKD-1 signaling and expression of ephrin B2 and smooth muscle actin in neovessels of Lewis Lung Carcinomas, along with low-CD36 expression or CD36 deficiency.
We also found that tubacin reduced cyst growth by inhibiting proliferation of cyst-lining epithelial cells, downregulated cyclic AMP levels, and improved renal function in a Pkd1-conditional mouse model of ADPKD.
In summary, we described a novel function of a multiple kinase inhibitor which strongly inhibits the VEGFR2-PKD1 signaling and might be a novel inhibitor of pathological inflammatory pathways.
Conversely, in EGR1 short hairpin RNA lentivirally transduced THP-1 cells, reduced EGR1 led to a significant up-regulation of PKD1, especially after treatment with pioglitazone.
Examples of such pClasper mediated gene modifications include: Claspette-mediated capture of large-insert genomic fragments from BACs-human polycystic kidney disease-1 (PKD1); modification of pClasperA clones by the RareGap method-PKD1 mutations; Claspette-mediated modification of pClasper clones-mouse albumin-1 gene; and, of most relevance to our interest in lymph node vasculature-Claspimer-mediated modification of pClasper clones-high endothelial venule and lymphatic vessel genes.
Indeed, we show here that in Pkd1 conditional deletion mice expression of the PCP component Four-jointed (Fjx1) is decreased while its expression is required during tissue regeneration.
Multivariable logistic regression analysis with adjustment for conventional risk factors revealed that the -572G-->C polymorphism of the interleukin-6 (IL-6) gene (IL6) was significantly (P<0.001) associated with both atherothrombotic cerebral infarction and intracerebral hemorrhage and that the -55C-->T polymorphism of the uncoupling protein 3 gene (UCP3), the -863C-->A polymorphism of the tumor necrosis factor (TNF) gene (TNF), and the G-->A (Gly243Asp) polymorphism of the polycystic kidney disease 1-like gene (PKD1-like) were significantly associated with subarachnoid hemorrhage.

Although the D298 ENOS allele may be associated with lower vascular activity of eNOS, this did not correlate with severity of renal disease in this PKD1 population.
Some of these alterations suggest mechanisms by which HGF/SF may exert its protective activity, e.g., up-regulation of polycystic kidney disease-1 (a survival-promoting component of cadherin-catenin complexes), down-regulation of 51C (an inositol polyphosphate-5-phosphatase), and down-regulation of TOPBP1 (a topoisomerase IIB binding protein).

This study strongly suggests that PKD 1 patients homozygous for the deletion allele of the ACE gene are at increased risk of developing ESRF at a early age.
Further mutations of the PBP gene were found in PKD1 patients, two deletions (one a de novo event) and a splicing defect, confirming that PBP is the PKD1 gene.
