Single molecule microscopy reveals key physical features of repair foci in living cells

J Miné-Hattab, M Heltberg, M Villemeur, C Guedj… - Elife, 2021 - elifesciences.org
In response to double strand breaks (DSB), repair proteins accumulate at damaged sites,
forming membrane-less sub-compartments or foci. Here we explored the physical nature of …

[PDF][PDF] Enhanced DNA repair through droplet formation and p53 oscillations

MS Heltberg, A Lucchetti, FS Hsieh, DPM Nguyen… - Cell, 2022 - cell.com
Living organisms are constantly exposed to DNA damage, and optimal repair is therefore
crucial. A characteristic hallmark of the response is the formation of sub-compartments around …

[HTML][HTML] Noise induces hopping between NF-κB entrainment modes

M Heltberg, RA Kellogg, S Krishna, S Tay, MH Jensen - Cell systems, 2016 - cell.com
Oscillations and noise drive many processes in biology, but how both affect the activity of the
transcription factor nuclear factor κB (NF-κB) is not understood. Here, we observe that when …

[PDF][PDF] A tale of two rhythms: Locked clocks and chaos in biology

ML Heltberg, S Krishna, LP Kadanoff, MH Jensen - Cell Systems, 2021 - cell.com
… chaos from lower dimensional dynamics, is to construct a Poincare section inside the embedded
attractor and determine the correlations of the points in this section (Heltberg et al., 2017…

[PDF][PDF] Chaotic dynamics mediate brain state transitions, driven by changes in extracellular ion concentrations

R Rasmussen, MH Jensen, ML Heltberg - Cell systems, 2017 - cell.com
Previous studies have suggested that changes in extracellular ion concentrations initiate
the transition from an activity state that characterizes sleep in cortical neurons to states that …

Coupled oscillator cooperativity as a control mechanism in chronobiology

MS Heltberg, Y Jiang, Y Fan, Z Zhang, MS Nordentoft… - Cell Systems, 2023 - cell.com
Control of dynamical processes is vital for maintaining correct cell regulation and cell-fate
decisions. Numerous regulatory networks show oscillatory behavior; however, our knowledge …

Physical observables to determine the nature of membrane-less cellular sub-compartments

ML Heltberg, J Miné-Hattab, A Taddei, AM Walczak… - Elife, 2021 - elifesciences.org
The spatial organization of complex biochemical reactions is essential for the regulation of
cellular processes. Membrane-less structures called foci containing high concentrations of …

[HTML][HTML] A possible universal role for mRNA secondary structure in bacterial translation revealed using a synthetic operon

Y Chemla, M Peeri, ML Heltberg, J Eichler… - Nature …, 2020 - nature.com
In bacteria, translation re-initiation is crucial for synthesizing proteins encoded by genes that
are organized into operons. The mechanisms regulating translation re-initiation remain, …

[HTML][HTML] Machine-learning vs. logistic regression for preoperative prediction of medical morbidity after fast-track hip and knee arthroplasty—a comparative study

C Michelsen, CC Jørgensen, M Heltberg… - BMC …, 2023 - Springer
Background Machine-learning models may improve prediction of length of stay (LOS) and
morbidity after surgery. However, few studies include fast-track programs, and most rely on …
