The ups and downs of p53: understanding protein dynamics in single cells

E Batchelor, A Loewer, G Lahav - Nature Reviews Cancer, 2009 - nature.com
Cells living in a complex environment must constantly detect, process and appropriately
respond to changing signals. Therefore, all cellular information processing is dynamic in nature. …

p53 dynamics control cell fate

JE Purvis, KW Karhohs, C Mock, E Batchelor, A Loewer… - Science, 2012 - science.org
Cells transmit information through molecular signals that often show complex dynamical
patterns. The dynamic behavior of the tumor suppressor p53 varies depending on the stimulus; …

Circular RNAs are a large class of animal RNAs with regulatory potency

…, LH Gregersen, M Munschauer, A Loewer… - Nature, 2013 - nature.com
Circular RNAs (circRNAs) in animals are an enigmatic class of RNA with unknown function.
To explore circRNAs systematically, we sequenced and computationally analysed human, …

Homo‐and heterodimerization of APP family members promotes intercellular adhesion

P Soba, S Eggert, K Wagner, H Zentgraf, K Siehl… - The EMBO …, 2005 - embopress.org
Lower levels of APLP2ΔCT interaction are due to lower expression levels of this construct.
(C) Heterointeraction of APP, APLP1, and APLP2 with different deletion constructs in COS7 …

We are all individuals: causes and consequences of non-genetic heterogeneity in mammalian cells

A Loewer, G Lahav - Current opinion in genetics & development, 2011 - Elsevier
The human body is formed by trillions of individual cells. These cells work together with
remarkable precision, first forming an adult organism out of a single fertilized egg, and then …

[HTML][HTML] Basal dynamics of p53 reveal transcriptionally attenuated pulses in cycling cells

A Loewer, E Batchelor, G Gaglia, G Lahav - Cell, 2010 - cell.com
The tumor suppressor p53 is activated by stress and leads to cellular outcomes such as
apoptosis and cell-cycle arrest. Its activation must be highly sensitive to ensure that cells react …

Stimulus‐dependent dynamics of p53 in single cells

E Batchelor, A Loewer, C Mock… - Molecular systems biology, 2011 - embopress.org
Many biological networks respond to various inputs through a common signaling molecule
that triggers distinct cellular outcomes. One potential mechanism for achieving specific input–…

[PDF][PDF] Cell-to-cell variation in p53 dynamics leads to fractional killing

AL Paek, JC Liu, A Loewer, WC Forrester, G Lahav - Cell, 2016 - cell.com
Many chemotherapeutic drugs kill only a fraction of cancer cells, limiting their efficacy. We
used live-cell imaging to investigate the role of p53 dynamics in fractional killing of colon …

Prolonged mitotic arrest triggers partial activation of apoptosis, resulting in DNA damage and p53 induction

JD Orth, A Loewer, G Lahav… - Molecular biology of the …, 2012 - Am Soc Cell Biol
Mitotic arrest induced by antimitotic drugs can cause apoptosis or p53-dependent cell cycle
arrest. It can also cause DNA damage, but the relationship between these events has been …

Disorder and residual helicity alter p53-Mdm2 binding affinity and signaling in cells

…, W Manieri, C Dieterich, P Selenko, A Loewer… - Nature chemical …, 2014 - nature.com
Levels of residual structure in disordered interaction domains determine in vitro binding
affinities, but whether they exert similar roles in cells is not known. Here, we show that increasing …
