Project description:Cardiovascular complications are the leading cause of death in autosomal dominant polycystic kidney disease (ADPKD), and intracranial aneurysm (ICA) causing subarachnoid hemorrhage is among the most serious complications. The diagnostic and therapeutic strategies for ICAs in ADPKD have not been fully established. We here generated induced pluripotent stem cells (iPSCs) from seven ADPKD patients, including four with ICAs. The vascular cells differentiated from ADPKD-iPSCs showed altered Ca2+ entry and gene expression profiles compared with those from control-iPSCs. We found that the expression level of a metalloenzyme gene, matrix metalloproteinase (MMP) 1, was specifically elevated in the iPSC-derived endothelia from ADPKD patients with ICAs. Furthermore, we confirmed a statistically significant correlation between the serum MMP1 levels and the development of ICAs in 354 ADPKD patients, indicating that the serum MMP1 levels may be a novel risk factor and become more beneficial when combined with other risk factors. These results suggest that cellular disease models with ADPKD-specific iPSCs can be used to study the disease mechanisms and to identify novel disease-related molecules or risk factors. The gene expression profiles of vascular endothelia and smooth muscle cells derived from ADPKD-iPSCs were analyzed. Seven ADPKD-iPSC derived ECs, and seven ADPKD-iPSC derived SMCs were analyzed.

The gene expression profiles of vascular endothelia and smooth muscle cells derived from control- and ADPKD-iPSCs were analyzed. Seven control-iPSC derived endothelial cells (ECs), seven ADPKD-iPSC derived ECs, ten control-iPSC derived vascular smooth muscle cells (SMCs), and seven ADPKD-iPSC derived SMCs were analyzed.

We here generated induced pluripotent stem cells (iPSCs) from seven ADPKD patients, including four with ICAs. The vascular cells differentiated from ADPKD-iPSCs showed altered Ca(2+) entry and gene expression profiles compared with those of iPSCs from non-ADPKD subjects. We found that the expression level of a metalloenzyme gene, matrix metalloproteinase (MMP) 1, was specifically elevated in iPSC-derived endothelia from ADPKD patients with ICAs. Furthermore, we confirmed the correlation between the serum MMP1 levels and the development of ICAs in 354 ADPKD patients, indicating that high serum MMP1 levels may be a novel risk factor. These results suggest that cellular disease models with ADPKD-specific iPSCs can be used to study the disease mechanisms and to identify novel disease-related molecules or risk factors.

Project description:We carried out a case control study in an attempt to identify changes in circulating microRNAs in patients with intracranial aneurysms (IAs). We selected 40 cases (20 ruptured and 20 unruptured) and 20 healthy controls. We randomly selected 5 samples from each group and combined them into a sample pool. In this way we obtained 12 sample pools and one pool was used for a single microarray. Changes in microRNA levels in the plasma were surveyed with Agilent Human microRNA Microarray (Release 14.0, 8x15K). We identified 20 microRNAs that were unanimously changed in both ruptured and unruptured patients.

Total RNA was isolated from 1 ml plasma from each sample pool and resuspended in the same volume of buffer. A fixed volume of RNA sample was used for microarray detection.
