Cytoplasmic Microinjection of piggyBac Transposase mRNA and Transposon Vectors for Efficient In Vitro Production of Transgenic Porcine Parthenotes

Received: 07 July 2022;  Published: 29 September 2022;  doi: 10.21926/obm.genet.2203166

Abstract

The efficient production of transgenic (Tg) piglets has remained a challenge in the field of domestic animal studies. Unlike mice, the pronuclei of pig zygotes cannot be easily studied because of the abundance of lipid droplets. Therefore, the zygotes must be briefly centrifuged before pronuclear injection (PNI) to move the lipid droplets to the periphery of the zygote for PNI-mediated production of Tg piglets. However, this procedure is temporal because lipid droplets return to the original spa [...]

Newborn Screening in Gaucher Disease: A Bright and Complicated Future

Received: 20 July 2022;  Published: 26 September 2022;  doi: 10.21926/obm.genet.2203165

Abstract

Gaucher disease (GD) is one of the most common lysosomal storage disorders resulting from biallelic mutations in the GBA1 gene, causing a dysfunction of the lysosomal hydrolase, glucocerebrosidase (acid-β-glucosidase; E.C 3.2.1.45). Clinical manifestations are heterogenous and can include splenomegaly, anemia, and neurological impairments in the case of neuronopathic Gaucher disease types 2 and 3. Newborn screening, arguably the most important public health initiative to dat [...]

Successive Detection of Telomerase by IHC and Assessment of Telomere Length by Q-FISH in Paucicellular Cumulus Samples from Cumulus-Oocyte Complexes Obtained in Assisted Reproduction Programs

Received: 13 May 2022;  Published: 23 September 2022;  doi: 10.21926/obm.genet.2203164

Abstract

This paper suggests an approach for the use of a single paucicellular histological sample to investigate two characteristics indicative of the cell’s functional potential: 1) the content of telomerase reverse transcriptase (TERT) and 2) the telomere length. An algorithm has been suggested for the successive detection of the catalytic telomerase subunit with immunohistochemical staining and assessment of telomere length with Q-FISH on the same set of cells. The described approach uses [...]

High-Altitude Pulmonary Edema in the Context of COVID-19

Received: 18 July 2022;  Published: 09 September 2022;  doi: 10.21926/obm.genet.2203163

Abstract

High-altitude pulmonary edema (HAPE) and COVID-19 pneumonia are different diseases, but HAPE-susceptible individuals (whose susceptibility often has a genetic basis) can also suffer from severe COVID-19. We hypothesized that certain pathogenic mechanisms might overlap if such a coincidence occurs, since these patients could react to alveolar hypoxia with a more intense and heterogeneously distributed pulmonary vasoconstriction than non-HAPE-susceptible patients. It is also not known [...]

Trisomy 14 Mosaicism Including Concomitant Uniparental Disomy: Population Frequency, Cytogenetic Profile, Sex Ratio, Maternal Age and Obstetric History

Received: 02 May 2022;  Published: 05 September 2022;  doi: 10.21926/obm.genet.2203162

Abstract

Mosaicism for trisomy of chromosome 14 (T14) is a very rare chromosomal disease in liveborn patients. Since the 1970s, when the first patients with mosaicism for T14 were reported, a number of studies on the clinical manifestations of this abnormality have been published. No information on epidemiological parameters was known except for the rarity of the disease and its predominance among female carriers. This was the first systematic review of published cases of mosaic T14 that addressed some e [...]

Newborn Screening for Classic Galactosemia: Biochemical Testings, Challenges, and Future

Received: 04 May 2022;  Published: 02 August 2022;  doi: 10.21926/obm.genet.2203161

Abstract

Galactosemia is a group of hereditary disorders of galactose metabolism. Newborn screening for galactosemia type I is mandatory in all states in the US since timely intervention can prevent life-threatening sequela. The biochemical basis, clinical presentation, and potential treatment options for different types of galactosemia are described. This review has a focus on the screening methodologies, including the principle of the assay, the transition from the initial bacteria inhibition test to t [...]
