DNA sequencing with chain-terminating inhibitors [PDF]

open access: greenProceedings of the National Academy of Sciences of the United States of America, 1977
A new method for determining nucleotide sequences in DNA is described. It is similar to the "plus and minus" method [Sanger, F. & Coulson, A. R. (1975) J. Mol. Biol.

435 Age-dependent Regulation of Follicle-Stimulating Hormone N-glycosylation in Female Gonadotrope Cells

open access: yesJournal of Clinical and Translational Science, 2022
OBJECTIVES/GOALS: Age-specific N-glycosylation occurs on follicle- stimulating hormone (FSH) in pituitaries of post-menopausal women and results in a higher ratio of fully glycosylated to hypoglycosylated FSH.

DNA 5-methylcytosine detection and methylation phasing using PacBio circular consensus sequencing

open access: yesbioRxiv, 2023
Long single-molecular sequencing, such as PacBio circular consensus sequencing (CCS) and nanopore sequencing, is advantageous in detecting DNA 5-methylcytosine (5mC) in CpGs, especially in repetitive genomic regions.

Long-Read DNA Sequencing: Recent Advances and Remaining Challenges.

open access: yesAnnual review of genomics and human genetics (Print), 2023
DNA sequencing has revolutionized medicine over recent decades. However, analysis of large structural variation and repetitive DNA, a hallmark of human genomes, has been limited by short-read technology, with read lengths of 100-300 bp.

Relationships of gut microbiota, short-chain fatty acids, inflammation, and the gut barrier in Parkinson’s disease

open access: yesMolecular Neurodegeneration, 2021
Background Previous studies have reported that gut microbiota, permeability, short-chain fatty acids (SCFAs), and inflammation are altered in Parkinson’s disease (PD), but how these factors are linked and how they contribute to disease processes and ...

Population-wide gene disruption in the murine lung epithelium via AAV-mediated delivery of CRISPR-Cas9 components

open access: yesMolecular Therapy: Methods & Clinical Development, 2022
With the aim of expediting drug target discovery and validation for respiratory diseases, we developed an optimized method for in situ somatic gene disruption in murine lung epithelial cells via AAV6-mediated CRISPR-Cas9 delivery.

Multiomics implicate gut microbiota in altered lipid and energy metabolism in Parkinson’s disease

open access: yesnpj Parkinson's Disease, 2022
We aimed to investigate the link between serum metabolites, gut bacterial community composition, and clinical variables in Parkinson’s disease (PD) and healthy control subjects (HC).

Sequencing DNA with nanopores: Troubles and biases

open access: yesPLoS ONE, 2021
Oxford Nanopore Technologies’ (ONT) long read sequencers offer access to longer DNA fragments than previous sequencer generations, at the cost of a higher error rate. While many papers have studied read correction methods, few have addressed the detailed
