Single-molecule visualization of DNA G-quadruplex formation in live cells

…, M Catalano, X Zhang, J Shen, LM Needham… - Nature …, 2020 - nature.com
Substantial evidence now exists to support that formation of DNA G-quadruplexes (G4s) is
coupled to altered gene expression. However, approaches that allow us to probe G4s in living …

Rational design of a conformation-specific antibody for the quantification of Aβ oligomers

…, S Chhangur, LM Needham… - Proceedings of the …, 2020 - National Acad Sciences
Protein misfolding and aggregation is the hallmark of numerous human disorders, including
Alzheimer’s disease. This process involves the formation of transient and heterogeneous …

[PDF][PDF] Poly (ADP-Ribose) links the DNA damage response and biomineralization

…, A Verhulst, PC D'Haese, E Neven, LM Needham… - Cell reports, 2019 - cell.com
Biomineralization of the extracellular matrix is an essential, regulated process. Inappropriate
mineralization of bone and the vasculature has devastating effects on patient health, yet an …

[HTML][HTML] ThX–a next-generation probe for the early detection of amyloid aggregates

LM Needham, J Weber, JA Varela, JWB Fyfe… - Chemical …, 2020 - pubs.rsc.org
Neurodegenerative diseases such as Alzheimer's and Parkinson's are associated with
protein misfolding and aggregation. Recent studies suggest that the small, rare and …

Spectrally resolved photodynamics of individual emitters in large-area monolayers of hexagonal boron nitride

…, R Wang, Y Fan, R Mizuta, JC Stewart, LM Needham… - ACS …, 2019 - ACS Publications
Hexagonal boron nitride (h-BN) is a 2D, wide band gap semiconductor that has recently
been shown to display bright room-temperature emission in the visible region, sparking …

[HTML][HTML] Wild-type sTREM2 blocks Aβ aggregation and neurotoxicity, but the Alzheimer's R47H mutant increases Aβ aggregation

…, F Chen, Y Zhang, P Flagmeier, LM Needham… - Journal of Biological …, 2021 - ASBMB
TREM2 is a pattern recognition receptor, expressed on microglia and myeloid cells, detecting
lipids and Aβ and inducing an innate immune response. Missense mutations (eg, R47H) of …

[HTML][HTML] Live-cell three-dimensional single-molecule tracking reveals modulation of enhancer dynamics by NuRD

…, J Balmer, TA Drury, AR Carr, LM Needham… - Nature structural & …, 2023 - nature.com
To understand how the nucleosome remodeling and deacetylase (NuRD) complex regulates
enhancers and enhancer–promoter interactions, we have developed an approach to …

[HTML][HTML] Single-molecule fluorescence detection of a tricyclic nucleoside analogue

GN Samaan, MK Wyllie, JM Cizmic, LM Needham… - Chemical …, 2021 - pubs.rsc.org
Fluorescent nucleobase surrogates capable of Watson–Crick hydrogen bonding are
essential probes of nucleic acid structure and dynamics, but their limited brightness and short …

[HTML][HTML] FRET-enhanced photostability allows improved single-molecule tracking of proteins and protein complexes in live mammalian cells

S Basu, LM Needham, D Lando, EJR Taylor… - Nature …, 2018 - nature.com
A major challenge in single-molecule imaging is tracking the dynamics of proteins or
complexes for long periods of time in the dense environments found in living cells. Here, we …

A comparative photophysical study of structural modifications of Thioflavin T-inspired fluorophores

LM Needham, J Weber, CM Pearson… - The journal of …, 2020 - ACS Publications
The benzothiazolium salt, Thioflavin T (ThT), has been widely adopted as the “gold-standard”
fluorescent reporter of amyloid in vitro. Its properties as a molecular rotor result in a large-…
