Therapy for Myhre Syndrome: Goals, Misconceptions, and Current Agents

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre Syndrome (MYHRS, MIM #139210) is a rare, multisystem connective tissue disorder caused by recurrent heterozygous gain‐of‐function pathogenic variants in the SMAD4 gene, a key player in TGF‐β signaling and a regulator of extracellular matrix homeostasis.

Precise base editing of non-allelic acetolactate synthase genes confers sulfonylurea herbicide resistance in maize

open access: yesCrop Journal, 2020
Single-nucleotide polymorphisms contribute to phenotypic diversity in maize. Creation and functional annotation of point mutations has been limited by the low efficiency of conventional methods based on random mutation.

Construction of a cytidine base editor based on Exopalaemon carinicauda cytidine deaminase and its application in crustacean genome editing

open access: yesAquaculture Reports, 2022
Economic crustaceans play important roles in aquaculture and create great benefits for the world agricultural economy. Studies have found that there are many single nucleotide polymorphism (SNP) sites in the crustacean genomes, which closely related to a

Comparison of cytosine base editors and development of the BEable-GPS database for targeting pathogenic SNVs [PDF]

open access: yesGenome Biology, 2019
Abstract A variety of base editors have been developed to achieve C-to-T editing in different genomic contexts. Here, we compare a panel of five base editors on their C-to-T editing efficiencies and product purity at commonly editable sites, including some human pathogenic C-to-T mutations.

One‐step generation of heritable mitochondrial DNA multiplex‐engineered rats using DddA‐derived cytosine base editor

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established that mixed DdCBE microinjection is an efficient, heritable, and precise strategy for generating multiplex mtDNA mutant rats. This advancement significantly expands the utility of DdCBEs for mitochondrial disease modeling, providing a robust platform for exploring the pathogenic mechanisms of complex mtDNA mutations and developing ...

Evaluation and minimization of Cas9-independent off-target DNA editing by cytosine base editors

open access: yesNature Biotechnology, 2020
Cytosine base editors (CBEs) enable targeted C•G-to-T•A conversions in genomic DNA. Recent studies report that BE3, the original CBE, induces a low frequency of genome-wide Cas9-independent off-target C•G-to-T•A mutation in mouse embryos and in rice. Here we develop multiple rapid, cost-effective methods to screen the propensity of different CBEs to ...

Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]

open access: yes, 2008
The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

Expanded base editing in rice and wheat using a Cas9-adenosine deaminase fusion

open access: yesGenome Biology, 2018
Nucleotide base editors in plants have been limited to conversion of cytosine to thymine. Here, we describe a new plant adenine base editor based on an evolved tRNA adenosine deaminase fused to the nickase CRISPR/Cas9, enabling A•T to G•C conversion at ...

Base Editing Mediated Generation of Point Mutations Into Human Pluripotent Stem Cells for Modeling Disease

open access: yesFrontiers in Cell and Developmental Biology, 2020
Human pluripotent stem cells (hPSCs) are a powerful platform for disease modeling and drug discovery. However, the introduction of known pathogenic mutations into hPSCs is a time-consuming and labor-intensive process.

DNA methylation profiling of the human major histocompatibility complex: A pilot study for the Human Epigenome Project [PDF]

open access: yes, 2004
The Human Epigenome Project aims to identify, catalogue, and interpret genome-wide DNA methylation phenomena. Occurring naturally on cytosine bases at cytosine-guanine dinucleotides, DNA methylation is intimately involved in diverse biological processes ...
