DNA microarrays of Wilson's disease patient-specific induced pluripotent stem cells

ABSTRACT: Wilson’s disease (WD) is a relevant human genetic disease caused by mutations in the ATP7B gene, whose product is a liver enzyme responsible for copper export into bile and blood. Interestingly, the spectrum of ATP7B mutations is vast and can influence clinical presentation (a variable spectrum of hepatic and neural manifestations), though the reason for this is not well understood. Here we describe the successful generation of iPSCs from a Chinese patient with Wilson’s disease that bears the R778L Chinese hotspot mutation in the ATP7B gene. Global gene expression profiling with DNA microarrays showed that WD iPSCs cluster together with human ESCs (H9) compared to donor fibroblasts. WD patient fibroblasts were isolated and expanded from a dermal biopsy of a middle age Chinese Han male, WD iPSCs were generated by overexpression of human Oct4/Sox2/Klf4/c-Myc in WD fibroblasts and expanded on Matrigel with mTESR1 culture medium. For DNA microarray analysis, WD fibroblasts (passage 5), 3 cell lines of WD iPSCs growing on Matrigel (passage 8) and human ES H9 growing on Matrigel (passage 40) were treated with Trizol, followed by RNA extraction and hybridization.

Recapitulation of human premature aging by using iPSCs from Hutchinson-Gilford progeria syndrome

Project description:Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature aging disease1-5, characterized by premature atherosclerosis and degeneration of vascular smooth muscle cells (SMCs)6-8. HGPS is caused by a single-point mutation in the LMNA gene, resulting in the generation of progerin, a truncated mutant of lamin A. Accumulation of progerin leads to various aging-associated nuclear defects including disorganization of nuclear lamina and loss of heterochromatin9-12. Here, we report the generation of induced pluripotent stem cells (iPSCs) from fibroblasts obtained from patients with HGPS. HGPS-iPSCs show absence of progerin, and more importantly, lack the nuclear envelope and epigenetic alterations normally associated with premature aging. Upon differentiation of HGPS-iPSCs, progerin and its associated aging consequences are restored. In particular, directed differentiation of HGPS-iPSCs to SMCs leads to the appearance of premature senescent SMC phenotypes associated with vascular aging. Additionally, our studies identify DNA-dependent protein kinase catalytic subunit (DNAPKcs) as a component of the progerin-containing protein complex. The absence of nuclear DNAPKcs correlates with premature as well as physiological aging. Since progerin also accumulates during physiological aging6,12,13, our results provide an in vitro iPSC-based model with an acceleration progerin accumulation to study the pathogenesis of human premature and physiological vascular aging. Microarray gene expression profiling was done to: (1) Compare differences between WT fibroblasts and fibroblasts from patients suffering of the Hutchinson-Gilford progeria syndrome (2) Check that iPSC originating from WT and patients are in fact similar to ESC

Attenuation of early atherogenesis in LDLR-KO mice by proteasome inhibition

Project description:To get further insights into the processes leading to attenuation of early stage atherosclerosis in the bortezomib treated LDLR-KO mice, microarray profiling of gene expression was performed on RNA taken from whole aortae of bortezomib treated LDLR-KO and sham- treated LDLR-KO mice fed a Western diet for 6 weeks and compared the changes in gene expression in both groups to non-atherosclerotic CD animals. Male 10-week-old LDLR-KO mice (B6.129S7-Ldlrtm1Her/J; JAX Mice, Boston) were fed a Western-type diet for 6 weeks ad libitum and received intraperitoneal injections of bortezomib (50 µg/kg body weight; WD+Bor) or saline (WD) twice weekly (n = 4). Mice that were fed normal diet served as chow diet control (CD; n = 4). Gene expression in aortic tissue was measured. Two independent experiments were performed.

Gene expression profiles of induced pluripotent stem cells (iPSCs) and skin fibroblasts from orangutans

Project description:Orangutans are an endangered species whose natural habitats are restricted to the Southeast Asian islands of Borneo and Sumatra. For potential species conservation and functional genomics studies, we derived induced pluripotent stem cells (iPSCs) from cryopreserved skin fibroblasts obtained from captive orangutans. We report the gene expression profiles of iPSCs and skin fibroblasts derived from orangtuans. The overall goal was to evaluate gene expression biomarkers of pluripotency in iPSCs and skin fibroblasts derived from PBD-ZSD patients and healthy controls. Dermal fibroblast cultures from 2 orangutans were reprogrammed into iPSCs by transfection with retroviruses designed to express the human OCT4, SOX2, KLF4 and c-MYC cDNA. Fibroblasts and iPSCs were cultured in 1:1 ratio of DMEM:F12 medium supplemented with 20% KOSR (knock-out serum replacement) at 37°C with 5% CO2 until confluence for RNA extraction. The overall goal was to evaluate gene expression biomarkers of pluripotency in iPSCs and original fibroblast cultures.

The proteomic study of serially passaged human skin fibroblast cells uncovers down-regulation of SMC4 involved in replicative senescence

Project description:In this study, a label-free quantitative proteomic approach was employed to analyze the serial passaged human skin fibroblast （CCD-1079Sk） cells, within 3305 proteins quantified. Of which, 372 proteins were significantly changed in early passage(P6), middle passage (P12) and later passage (P21), with a time-dependent decrease or increase tendency. Then, of which, SMC4 was selected for further biological validation. The results confirmed that the expression of SMC4 was significantly down-regulated in a time-dependent manner in the subculture of human skin fibroblasts (HSFb) with Western Blot experiment.

Expression data in induced pluripotent stem cells (iPSCs) derived from a DNA repair deficient fibroblast

Project description:Cockayne syndrome (CS) is an autossomal human disorder characterized by premature aging along with other symptoms. At the molecular level, CS is characterized by a deficiency in the Transcription-couple DNA repair pathway caused by a mutation mainly in ERCC6 gene and the absence of its functional protein. It has been shown that the presence of DNA damage and the lack of some functional proteins related to DNA repair constitute a barrier for somatic cell reprogramming. Recently, it was demonstrated that one protein involved in Genome Global Repair controls the expression of an important pluripotent gene, highligting its importance for cellular reprogramming. We used microarray to confirm cellular reprogramming of CS fibroblasts at the molecular level and detail the expression of some genes invoved in cell death and aging control that might explain the unique characteristics of these iPSCs. Normal (wild type) and fibroblasts from a CS patient were reprogrammed and independent clones were isolated. After sucessive passages in culture, total RNA from donor fibroblasts, iPSCs clones and human embryonic stem cell line (HUES6) were isolated and transcriptional analysis using human genome Affimetrix Gene Chip arrays were performed. HUES6 was used to demonstrate that CS and normal iPSCS show a global gene expression similar to an embryonic stem cell, confirming that both fibroblasts were successfully reprogrammed. We also used fibroblasts from CS to point out the diiferences in global gene expression after reprogramming. We sought to use normal (control) iPSCs to compare the levels of some genes involved in cell death and aging in iPSCs from CS fibroblasts.

Influence of ATM-mediated DNA damage response on genomic variation in human induced pluripotent stem cells (Affymetrix expression)

Project description:Genome instability is a potential limitation to the research and therapeutic application of induced pluripotent stem cells (iPSCs). Observed genomic variations reflect the combined activities of DNA damage, cellular DNA damage response (DDR), and selection pressure in culture. To understand the contribution of DDR on the distribution of copy number variations (CNVs) in iPSCs, we mapped CNVs of iPSCs with mutations in the central DDR gene ATM onto genome organization landscapes defined by genome-wide replication timing profiles. We show that following reprogramming the early and late replicating genome is differentially affected by CNVs in ATM deficient iPSCs relative to wild type iPSCs. Specifically, the early replicating regions had increased CNV losses during retroviral reprogramming. This differential CNV distribution was not present after later passage or after episomal reprogramming. Comparison of different reprogramming methods in the setting of defective DNA damage response reveals unique vulnerability of early replicating open chromatin to retroviral vectors. We isolated RNA from Ataxia-telangiectasia (A-T) patient fibroblast derived iPS cells and A-T patient fibroblasts for hybridization to the Affymetrix gene expression microarrays.
