Triple gene editing in porcine embryos using electroporation alone or in combination with microinjection [PDF]

open access: yesVeterinary World, 2022
Background and Aim: We previously developed the gene-editing by electroporation (EP) of Cas9 protein method, in which the CRISPR/Cas9 system was introduced into porcine in vitro fertilized (IVF) zygotes through EP to disrupt a target gene.

Enhanced Bacterial α(2,6)-Sialyltransferase Reaction through an Inhibition of Its Inherent Sialidase Activity by Dephosphorylation of Cytidine-5'-Monophosphate. [PDF]

open access: yesPLoS ONE, 2015
Bacterial α(2,6)-sialyltransferases (STs) from Photobacterium damsela, Photobacterium sp. JT-ISH-224, and P. leiognathi JT-SHIZ-145 were recombinantly expressed in Escherichia coli and their ST activities were compared directly using a galactosylated bi ...

Aberrant N-glycolylneuraminic acid in breast MCF-7 cancer cells and cancer stem cells

open access: yesFrontiers in Molecular Biosciences, 2022
N-Glycolylneuraminic acid (Neu5Gc) is not normally detected in humans because humans lack the hydroxylase enzyme that converts cytidine-5′-monophosphate-N-acetylneuraminic acid (CMP-Neu5Ac) to CMP-Neu5Gc; thus, any Neu5Gc appearing in the human body is ...

Molecular characterization of blood type A, B, and C (AB) in domestic cats and a CMAH genotyping scheme. [PDF]

open access: yesPLoS ONE, 2018
In domestic cats, the AB blood group system consists of the three types A, B, and C (usually called AB), which vary in frequency among breeds and geographic regions.

N-glycans: phenotypic homology and structural differences between myocardial cells and induced pluripotent stem cell-derived cardiomyocytes. [PDF]

open access: yesPLoS ONE, 2014
Cell surface glycans vary widely, depending on cell properties. We hypothesized that glycan expression on induced pluripotent stem cells (iPSCs) might change during cardiomyogenic differentiation toward the myocardial phenotype.

Comparison of lipooligosaccharides from human challenge strains of Neisseria gonorrhoeae

open access: yesFrontiers in Microbiology, 2023
The alarming rise of antibiotic resistance and the emergence of new vaccine technologies have increased the focus on vaccination to control gonorrhea. Neisseria gonorrhoeae strains FA1090 and MS11 have been used in challenge studies in human males.

Phenotypic and Genetic Characterization for Incompatible Cross-Match Cases in the Feline AB Blood Group System

open access: yesFrontiers in Veterinary Science, 2021
The feline AB blood group system (blood types A, B, and AB) encoding the cytidine monophosphate-N-acetylneuraminic acid hydroxylase (CMAH) gene is the most significant in transfusion medicine and hemolysis of the newborn for cats.

Ferrets exclusively synthesize Neu5Ac and express naturally humanized influenza A virus receptors [PDF]

open access: yes, 2014
Mammals express the sialic acids ​N-acetylneuraminic acid (​Neu5Ac) and ​N-glycolylneuraminic acid (​Neu5Gc) on cell surfaces, where they act as receptors for pathogens, including influenza A virus (IAV). ​Neu5Gc is synthesized from ​Neu5Ac by the enzyme

Clustered Regularly Interspaced Short Palindromic Repeats/Cas9 Gene Editing Technique in Xenotransplantation

open access: yesFrontiers in Immunology, 2018
Genetically modified pigs have been considered favorable resources in xenotransplantation. Microinjection of randomly integrating transgenes into zygotes, somatic cell nuclear transfer, homologous recombination, zinc finger nucleases, transcription ...
