Epigenetic Symmetry of DLGAP2: Pre-Implantation Maternal Methylation Switches to a Random Monoallelic Profile in Somatic Tissues

Received: 29 May 2018;  Published: 29 July 2018;  doi: 10.21926/obm.genet.1803026

Abstract

Background: Symmetrical DNA methylation profiles of autosomal genes are associated with equal expression by both alleles. Genes with an allelic imbalance or monoallelic expression are associated with discrete intervals of allele-specific methylation (ASM), as highlighted by genomic imprinting, X-chromosome inactivation and genotype-driven ASM. However, a more complex pattern has been described in which random monoallelic methylation provides cells with a unique mechanism for modulating allelic dosage. Methods: We c [...]

Experimental DNA- or RNA-Directed Therapies for Trinucleotide Repeat Disease

Received: 17 April 2018;  Published: 27 July 2018;  doi: 10.21926/obm.genet.1803025

Abstract

Some repeats of three or more nucleotides in tandem, which are present in a gene or in its vicinity, tend to increase in number and for this reason are called dynamic mutations. These triplet repeats are unstable and can expand from one generation to the next. According to the expansion size, an unaffected individual can carry a pre-mutation that will expand through generations leading to the development of triplet repeat expansion diseases. The increase in the number of repeats over time leads to earlier developme [...]

Positive Life Experiences Following a Dementia Diagnosis

Received: 15 June 2018;  Published: 26 July 2018;  doi: 10.21926/obm.geriatr.1803006

Abstract

Background: Given the stigma and fear associated with Alzheimer’s disease (AD), combined with the progressive nature of the disease, the diagnosis of AD or mild cognitive impairment (MCI) is often very difficult; yet, there may still be ways to experience some positive outcomes following diagnosis. We aim to assess the psychological impact of a diagnosis of MCI or early dementia on positive well-being. Methods: Individuals with a diagnosis of MCI or AD were mailed surveys with the Silver-Lining Questionnaire. Resul [...]

To Opt or Not to Opt for Preimplantation and/or Prenatal Genetic Testing?

Received: 05 June 2018;  Published: 23 July 2018;  doi: 10.21926/obm.genet.1803024

Abstract

Both preimplantation genetic testing (PGT) and prenatal diagnosis (PND) are powerful tools to tackle the transmission of inherited disorders carried by families from generation to generation. Here, we present an overview of the current landscape of both methods and identify the pros and cons of each of these reproductive options. In prenatal testing, non-invasive diagnostic methods have become available as an alternative for invasive diagnosis. Different genome sequencing strategies have now been introduced that en [...]

Unusual Ways to Lose a Y Chromosome and Survive with Changed Autosomes: a Story of Mole Voles Ellobius (Mammalia, Rodentia)

Received: 16 May 2018;  Published: 22 July 2018;  doi: 10.21926/obm.genet.1803023

Abstract

Species of mole voles Ellobius demonstrate a broad variation in sex chromosomes and autosomes, which is unique among mammals. In four species, a Y chromosome was lost, and X0 or XX sex chromosomes in both sexes were obtained. The key testis-determining Sry (Sex-determining Region on Y) gene is absent in these species, and the regulation of its target, the Sox9 (SRY -box 9) gene, is questionable due to deletion in the key enhancer. In a single species, E. fuscocapillus, with routine XX-XY, the same deletion is prese [...]

Autoimmunity in Autologous Islet Transplantation

Received: 29 March 2018;  Published: 02 July 2018;  doi: 10.21926/obm.transplant.1803014

Abstract

Total pancreatectomy (TP) is increasingly being utilized for definitive treatment in patients with debilitating chronic pancreatitis (CP). In an effort to prevent surgical diabetes, the procedure can be performed in conjunction with transplantation of islets of Langerhans recovered from the patients’ own resected pancreas (autologous islet transplantation, AIT). Given that patients undergoing TP and AIT are traditionally assumed not to be at risk for the development of beta-cell autoimmunity, it is possible that th [...]

Regulation of Inflammatory Response in Islet Transplantation

Received: 29 March 2018;  Published: 22 June 2018;  doi: 10.21926/obm.transplant.1802013

Abstract

Islet cell transplantation is a developing treatment for patients suffering from severe Type-1 diabetes. The long-term insulin independence after islet cell transplantation has been difficult to achieve, and this has been linked to several factors. One of the major cause of poor long-term outcome is inflammation surrounding the islets. Inflammation in islets is caused at several stages, donor induced, during organ preservation, islet isolation stress, peri-transplant inflammation or instant blood mediated inflammat [...]

On Objectivity in Prenatal Genetic Care

Received: 16 April 2018;  Published: 12 June 2018;  doi: 10.21926/obm.genet.1802022

Abstract

We address an ongoing controversy over what health-care providers tell prospective parents about Down Syndrome (DS). Many parent, disability-rights, and anti-abortion activists believe that the messages that health-care professionals transmit to pregnant women and their partners are distorted. In their view, OB-GYNs, primary-care providers, clinical geneticists, midwives and other medical professionals generally assume that the quality of life for individuals with DS and their families is poor, whereas in fact, tho [...]

Delayed Clinically Significant Portal Hypertension after Total Pancreatectomy-Islet Auto-Transplantation

Received: 21 March 2018;  Published: 12 June 2018;  doi: 10.21926/obm.transplant.1802011

Abstract

Portal hypertension often occurs transiently with injection of islet cells into the portal system during total pancreatectomy-islet autotransplantation (TPIAT). We describe a TPIAT patient with non-cirrhotic portal hypertension (NCPH) two years after surgery initially identified with esophageal varices on upper endoscopy. The underlying mechanism for the development of NCPH after TPIAT is unclear but infectious and immune-related pathways have been proposed. Management of NCPH is primarily treatment of complication [...]

Stem Cell Strategies to Promote Islet Transplantation Outcomes

Received: 02 April 2018;  Published: 05 June 2018;  doi: 10.21926/obm.transplant.1802010

Abstract

Pancreas or islet transplantation is the only reliable cure for Type 1 Diabetes. However, shortage of donor tissue supply, longitudinal graft attrition due to innate and adaptive immunity and the recurrence of autoimmunity, as well as the harmful side-effects of chronic immunosuppressive therapy limit the wide-spread acceptance of islet transplantation as a mainstream cure for autoimmune diabetes. Herein, preclinical and clinical stem-cells based research approaches aimed at obtaining large quantities of islets for [...]

Evolution in the Management of Invasive Fungal Infections in Liver Transplant Recipients

Received: 26 March 2018;  Published: 29 May 2018;  doi: 10.21926/obm.transplant.1802009

Abstract

Invasive fungal infections (IFI) remain an important cause of morbidity and mortality, especially in hospitalized and immunocompromised or critically ill patients. The incidence of IFIs has been declining in liver transplant recipients (LTR). This is likely due to the evolving immunosuppressive drug regimens, improved surgical techniques and targeted antifungal prophylaxis. However, IFI still contribute to high mortality and are associated with high economic burden due to consumption of costly newer antifungal agen [...]
