FY-hESC Micro-array raw data

ABSTRACT: Human embryonic stem cells (hESCs) exhibit a skewed X chromosome inactivation (XCI) have recently been reported. Whether there is any copy number variation (CNV), loss of heterozygousity (LOH) and single nucleotide variant (SNV) in those epigenetically distinct cells and whether these abnormalities have any correlation to skewed XCI in hESCs is currently unknown.

Affymetrix SNP array data for hepatocellular carcinoma tissue

Project description:Genetic variations play an important role in tumor development and metastasis. Hepatocellular carcinoma (HCC) is one of leading cause of cancer-related death. Despite improvements in surveillance and clinical treatment strategies, the prognosis of HCC remains dismal. Affymetrix SNP 6.0 array were used to evaluate the genetic characteristics of tumor DNA in 30 HBV-related HCC patients who were underwent liver transplantation. Recurrence related SNPs were selected and validated. Affymetrix SNP 6.0 arrays were performed according to the manufacturer's directions on DNA extracted from formalin-fixed paraffin-embedded HCC tissues

A Comparative Liver Label-Free Liquid Chromatography-Mass Spectrometry Proteomic Profile Highlights Putative Metabolic Differences Between two Pig Breeds

Project description:Pig breeds have different attitude to traits like growth rate, carcass composition and reproduction parameters as well as other traits. These traits considered as external traits or end phenotypes are the outcome of complex biological processes and interactions. The main goal of pig breeding programs and the basis for crossbreeding is finding a balance between these traits. In pig production, Large White and Duroc breeds are commonly used to optimise respectively fertility and growth ability and differ on several production traits, indeed the first breed as a high fertility characters whereas Duroc is used as terminal sire for her growth performance and good carcass quality traits. In this study, we have used a quantitative label-free LC-MS proteomics approach to characterise and compare the liver proteome of two heavy Italian pig breeds, Italian Duroc and Italian Large White to identify difference due to their different genetic background. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 703094.

Gene expression profiles of DFCs and SHED 48 hours after in vitro transfection with a TP53 plasmid, a SP1 plasmid, or an empty vector.

Project description:Dental follicle is a loose connective tissue that surrounds the developing tooth. Dental follicle cells (DFCs) have a promising potential for tissue engineering applications including periodontal and bone regeneration. However, little is known about the molecular mechanisms underlying osteogenic differentiation. In a previous study we detected that more than 35 % of genes that are regulated during osteogenic differentiation of DFCs have promoter binding sites for the transcription factors TP53 and SP1. However, the role of these transcription factors in dental stem cells is still unknown. We hypothesize that both factors influence the processes of cell proliferation and differentiation in dental stem cells. Therefore, we transiently transfected DFCs and dental pulp stem cells (SHED; Stem cells from human exfoliated decidiuous teeth) with expression vectors for these transcription factors. After overexpression of SP1 and TP53, SP1 influenced cell proliferation and TP53 osteogenic differentiation in both dental cell types. The effects on cell proliferation and differentiation were less pronounced after siRNA mediated silencing of TP53 and SP1. This indicates that the effects we observed after TP53 and SP1 overexpression are indirect and subject of complex regulation. Interestingly, upregulated biological processes in DFCs after TP53-overexpression resemble the downregulated biological processes in SHED after SP1-overexpression. Here, regulated processes are involved in cell motility, wound healing and programmed cell death. In conclusion, our study demonstrates that SP1 and TP53 influence cell proliferation and differentiation and similar biological processes in both SHED and DFCs. Total RNAs were isolated from dental follicle cells after 48 hours of transfection with a TP53 expressions plasmid, a SP1 expressions plasmid and for control with an empty vector.

Genomic profiling of immature hematopoietic cells to obtain insights into imatinib resistance

Project description:Chronic myeloid leukemia (CML) epitomizes successful targeted therapy, with 86% of patients in the chronic phase treated with tyrosine kinase inhibitors (TKIs) attaining remission. However, resistance to TKIs occurs during treatment, and patients with resistance to TKIs progress to the acute phase called Blast Crisis (BC), wherein the survival is restricted to 7-11 months. About 80 % of patients in BC are unresponsive to TKIs. This issue can be addressed by identifying a molecular signature which can predict resistance in CML-CP prior to treatment as well as by delineating the molecular mechanism underlying resistance. Herein, we report genomic analysis of CML patients and imatinib-resistant K562 cell line to achieve the same. Thirteen CML patients (sensitive and resistant to TKIs) and 2 BMT donors (as control) were recruited for the study. DNA was isolated from an enriched CD34+ fraction for each sample as well as from K562 cells made resistant to imatinib which provided a model system for further molecular investigations. DNA was subjected to Cytoscan HD array (Affymatrix) analysis from patient samples and cell lines. Affymetrix CytoScan™ HD array (Applied Biosystems™, Cat# 901835) chip consists of 2.6 M oligonucleotide probes across the genome, including 1953K unique non-polymorphic probes and 750K bi-allelic SNP (single nucleotide polymorphism) probes. Our study identified accumulation of aberrations on chromosomes 1, 3, 7, 16 and 22 as predictive of occurrence of resistance. Further, recurrent amplification in chromosomal region 8q11.2-12.1 was detected in highly resistant K562 cells as well as CML patients. The genes present in this region were analyzed to understand molecular mechanism of imatinib resistance.

De novo homozygous deletion of segmental KAL1 and entire STS cause Kallmann syndrome and X-linked ichthyosis in a Chinese family

Project description:Kallmann syndrome is a genetically heterogeneous condition and a treatable form of male infertility. Defects in KAL1 gene have been implicated in Kallmann syndrome, which can be associated with X-linked ichthyosis in contiguous gene syndromes. In order to uncover the genetic cause of two brothers with Kallmann syndrome and X-linked ichthyosis, a custom semiconductor targeted resequencing panel to detect seventeen Kallmann syndrome causal genes and STS gene was designed. Next-generation sequencing was performed using this panel in the two affected brothers and their normal parents. To validate the result, we applied CytoScanâ¢ HD array, quantitative real-time PCR and direct PCR electrophoresis analysis with the participants. The patients received clinical assessment, human chorionic gonadotropin treatment and follow-up for 39 months. The results showed that the two affected siblings have the same de novo deletion at Xp22.3 including exons 9-14 of KAL1 gene and entire STS gene but showed different phenotypes in some respects. The secondary sex characteristics of the patients were greatly improved after treatment. We firstly reported that a de novo homozygous deletion contribute to KS with bilateral cryptorchidism and unilateral renal agenesis or normal kidney development and developed a cost-effective and reliable semiconductor targeted resequencing panel for genetic diagnosis of Kallmann syndrome in routinely obtained samples. One of the two brothers with Kallmann syndrome and X-linked ichthyosis was analyzed for validation the results of the deletion detected by next-generation sequencing.
