Cover Story: COMBinatorial Oligo-nucleotide FISH (COMBO-FISH) in combination with immunostaining offers novel approaches to specifically label the native chromatin architecture by means of fluorescence super-resolution single molecule localization microscopy (SMLM). Unique, repetitively binding COMBO-FISH probes (e.g., for centromere 9, Alu consensus, L1 sequences etc.) in combination with specific antibodies (e.g., for heterochromatin, euchromatin, radiation damage foci, etc.) reveal characteristic patterns in cell nuclei as being measured by SMLM.

Open Access Review

The Role of Mitochondria in Oocyte and Early Embryo Health

Received: 01 January 2019;  Published: 29 March 2019;  doi: 10.21926/obm.genet.1901070

Abstract

The mitochondria of the oocyte are a prominent source of energy metabolism as well as mitochondrial DNA that will later populate the cells of the offspring. Recent discoveries provided new insight into the physiology of the mitochondria and its unique genetics. The concept of heteroplasmy defined as [...]

Clonal Heterogeneity in Non-Small Cell Lung Cancer and the Possible Role in Predicting Response to Treatment with Immune Checkpoint Inhibitors

Received: 15 November 2018;  Published: 22 March 2019;  doi: 10.21926/obm.genet.1901069

Abstract

Immune oncology treatment with immune checkpoint inhibitors (ICIs) is revolutionizing therapeutic approach for advanced non-small cell lung cancer (NSCLC) patients, in terms of longer survival and improved quality of life. To date, the widely used and approved biomarker is programmed death ligand 1 [...]

FISH-Based Analysis of Mosaic Aneuploidy and Chromosome Instability for Investigating Molecular and Cellular Mechanisms of Disease

Received: 08 February 2019;  Published: 20 March 2019;  doi: 10.21926/obm.genet.1901068

Abstract

Recently, numerous studies have reported convincing data suggesting that chromosome instability may be not only a trigger of cancers but a possible mechanism for a wide spectrum of brain diseases. According to our original experience, chromosome instability is commonly observed during karyotyping of [...]

Interphase Quantitative Fluorescence in Situ Hybridization (IQ-FISH)

Received: 02 February 2019;  Published: 20 March 2019;  doi: 10.21926/obm.genet.1901067

Abstract

Fluorescence in situ hybridization (FISH) seems to be the most applicable and versatile molecular cytogenetic platform for interphase chromosome analysis offering a variety of opportunities for studying chromosomal structure and behaviour at the highest microscopic resolution and at all stages of th [...]

New DNA Extraction Method for the Detection of Pneumocystis in Lung Tissue Samples of Colonized Individuals

Received: 30 January 2019;  Published: 18 March 2019;  doi: 10.21926/obm.genet.1901066

Abstract

Background: Pneumocystis jirovecii colonization in patients is associated with a low organism burden, which supports the need to use highly sensitive molecular techniques, such as nested-PCR to determine the presence of the organism. However, few studies have considered the effect of nucleic acid ex [...]

New Tools in Cognitive Neurobiology: Biotin-Digoxigenin Detection of Overlapping Active Neuronal Populations by Two-Color c-fos Compartment Analysis of Temporal Activity by Fluorescent in situ Hybridization (catFISH)

Received: 12 October 2018;  Published: 04 March 2019;  doi: 10.21926/obm.genet.1901065

Abstract

The method of cellular compartment analysis of temporal activity by fluorescent in situ hybridization (catFISH) is widely used in cellular and behavioral neurobiology. It exploits stimulus-induced expression of immediate early genes (IEGs) and allows identification of two neuronal populations activa [...]

COMBO-FISH: A Versatile Tool Beyond Standard FISH to Study Chromatin Organization by Fluorescence Light Microscopy

Received: 14 September 2018;  Published: 19 February 2019;  doi: 10.21926/obm.genet.1901064

Abstract

Background: Fluorescence In Situ Hybridization (FISH) has become routine for bio-medical research and medical diagnosis, thereby offering a variety of probes and ready-to-use kits that fulfil requirements for many applications. However, conventional FISH relies on chemo- and/or thermal denaturation [...]

Interphase FISH: A Helpful Assay in Prenatal Cytogenetics Diagnosis

Received: 01 October 2018;  Published: 28 January 2019;  doi: 10.21926/obm.genet.1901063

Abstract

Since its introduction around the end of the 1970s, interphase in situ hybridization supports classical and latest techniques for determining foetal karyotype in the prenatal diagnosis, providing relevant information for the management of pregnancy quickly. Interphase FISH plays an important role in [...]

Repli-FISH (Fluorescence in Situ Hybridization): Application of 3D-(Immuno)-FISH for the Study of DNA Replication Timing of Genetic Repeat Elements

Received: 22 July 2018;  Published: 25 January 2019;  doi: 10.21926/obm.genet.1901062

Abstract

Background: Genetic repeat elements (interspersed or tandem repeats) have diverse functions within cells and at different phases of the cell cycle. Yet, their investigation at a genome-wide scale has been difficult ever since due to their repetitive nature. Here, we describe a method to study the DN [...]

The Usefulness of Preimplantation Genetic Testing for Chromosome Aneuploidy Informed by A Randomised Controlled Trial

Received: 29 October 2018;  Published: 22 January 2019;  doi: 10.21926/obm.genet.1901061

Abstract

United Kingdom guidelines recommend single embryo transfer (fresh or cryopreserved) in the first full assisted conception cycle for women under 40 years most at risk of having twins. Based on a recent randomized clinical trial for women aged 36 to 40 years, the hypothetical effect of preimplantation [...]

Genotyping Pneumocystis jirovecii: Impacting Our Understanding of Interhuman Transmission

Received: 04 December 2018;  Published: 17 January 2019;  doi: 10.21926/obm.genet.1901060

Abstract

Pneumocystis jirovecii is an atypical fungus transmitted via interhuman airborn contact. This fungus is exclusively associated with humans and almost each individual has encountered it at least once before reaching the age of two. Pneumocystis jirovecii can be responsible for spontaneously resolutiv [...]
