Ebolavirus (EBOV), the causative agent of a severe hemorrhagic fever and a biosafety level 4 pathogen, increases its genome coding capacity by producing multiple transcripts encoding for structural and nonstructural glycoproteins from a single gene. This is achieved through RNA editing, during which non-template adenosine residues are incorporated into the EBOV mRNAs at an editing site encoding...
Kok et al. conclude that results with Morpholino oligos, which are not recapitulated by natural mutations or gene editing mutations, must be due to off-target effects and, when morphants and mutants differ, they contend that antisense oligo studies should be disregarded. Morpholinos and gene editing mutagenesis are very different technologies and, even if both work perfectly, may yield differen...
ABSTRACT Gene-editing technologies, ie those able to make changes in the DNA of an organism, are object global competition and a regulatory race between countries regions. There is attempt craft legal frameworks protective enough for users, but flexible developers gene-editing technologies. This article examines imaginary built into framing EU-level regulation human technologies identifies its ...
Objective(s): Oncolytic Herpes simplex virus type 1 (HSV-1) has emerged as a promising strategy for cancer therapy. However, development of novel oncolytic mutants has remained a major challenge owing to low efficiency of conventional genome editing methods. Recently, CRISPR-Cas9 has revolutionized genome editing.Materials and Methods: I...
Beta-thalassemia (β-thal) is a congenital hemoglobinopathy explained by a decreased level (β+) or absence (βο) of β-globin gene expression. Microcytic hypochromic anemia and various clinical symptoms comprising severe anemia to clinically nonsymptomatic features. Treatment with an ordered blood transfusion and iron chelator agents can decrease transfusion iron overload that causes normal matura...
Gene editing directed by modified single-stranded DNA oligonucleotides has been used to alter a single base pair in a variety of biological systems. It is likely that gene editing is facilitated by the direct incorporation of the oligonucleotides via replication and/or by direct conversion, most likely through the DNA mismatch repair pathway. The phenomenon of strand bias, however, as well as i...
CRISPR-Cas9 gene editing of human cells and tissues holds much promise to advance medicine and biology, but standard editing methods require weeks to months of reagent preparation and selection where much or all of the initial edited samples are destroyed during analysis. ArrayEdit, a simple approach utilizing surface-modified multiwell plates containing one-pot transcribed single-guide RNAs, s...
Single-stranded DNA oligonucleotides (ssODNs) can direct the repair of a single base mutation in human genes. While the regulation of this gene editing reaction has been partially elucidated, the low frequency with which repair occurs has hampered development toward clinical application. In this work a CRISPR/Cas9 complex is employed to induce double strand DNA breakage at specific sites surrou...
