The cytoskeleton is a crucial determinant of mammalian cell structure and function, providing mechanical resilience, supporting the cell membrane and orchestrating essential processes such as cell division and motility. Because of its fundamental role in living cells, developing a reconstituted or artificial cytoskeleton is of major interest. Here we present an approach to construct an artificial cytoskeleton that imparts mechanical support and regulates membrane dynamics.

Rapid mechanical phenotyping of breast cancer cells based on stochastic intracellular fluctuations.

iScience

November 2024

Bionanomechanics Lab, Instituto de Micro y Nanotecnología, IMN-CNM (CSIC), Tres Cantos, Madrid, Spain.

Predicting the phenotypic impact of genetic variants and treatments is crucial in cancer genetics and precision oncology. Here, we have developed a noise decorrelation method that enables quantitative phase imaging (QPI) with the capability for label-free noninvasive mapping of intracellular dry mass fluctuations within the millisecond-to-second timescale regime, previously inaccessible due to temporal phase noise. Applied to breast cancer cells, this method revealed regions driven by thermal forces and regions of intense activity fueled by ATP hydrolysis.

Article Synopsis
  • The study aims to assess how members of the ACL study group are incorporating lateral extra-articular procedures (LEAPs) in ACL reconstruction surgeries over recent years.
  • A survey shared during biennial meetings from 2016 to 2023 revealed an increase in the use of LEAP techniques, with surgeons preferring methods involving iliotibial band (ITB) autograft.
  • The findings indicate that LEAPs, particularly the modified Lemaire technique, are gaining popularity among surgeons, correlating with clinical evidence that suggests better outcomes when these procedures are used alongside traditional ACL reconstruction.

Aims: Evidence on the impact of screening for cardiovascular diseases (CVDs) on health-related quality of life (HRQoL) is important for policy decisions about screening implementation and to uncover teachable moments to motivate healthy lifestyle choices. It is unknown whether screening by cardiac computed tomography (CT) scan has a stronger impact on HRQoL than screening by traditional risk prediction models. The study aims to investigate differences in HRQoL across the screening process between participants who were randomized to CVD risk estimation by coronary artery calcium score or Systematic COronary Risk Evaluation.

Recombinant adeno-associated virus (rAAV)-based gene therapies are expanding in their application. Despite progress in manufacturing, current analytical methods for product quantification and characterization remain largely unchanged. Although critical for product and process development, in-process testing, and batch release, current analytical methods are labor-intensive, costly, and hampered by extended turnaround times and low throughput.

Competitive protein recruitment in artificial cells.

Commun Chem

June 2024

Laboratory of Chemical Biology, Department of Biomedical Engineering and Institute for Complex Molecular Systems, Eindhoven University of Technology, Eindhoven, The Netherlands.

Living cells can modulate their response to environmental cues by changing their sensitivities for molecular signals. Artificial cells are promising model platforms to study intercellular communication, but populations with such differentiated behavior remain underexplored. Here, we show the affinity-regulated exchange of proteins in distinct populations of coacervate-based artificial cells via protein-protein interactions (PPI) of the hub protein 14-3-3.

Stroke

May 2024

Department of Neurology, Henry and Allison McCance Center for Brain Health, Massachusetts General Hospital, Boston, MA (S.D.S., J.R.S., J.R.).

The Brain Health crisis stands as one of humankind's most pressing threats, with age-related noncommunicable brain diseases, particularly stroke, and dementia, affecting hundreds of millions annually and jeopardizing the economic well-being of populations worldwide. Epidemiological studies indicate that ≈40% of dementia and 60% of stroke cases are attributable to modifiable risk factors. In this Comments and Opinions article, we underscore the pivotal role of blood pressure (BP) control in reducing suffering, enhancing economic well-being, and promoting healthy longevity for populations worldwide.

Viscoadaptation is an essential process in natural cells, where supramolecular interactions between cytosolic components drive adaptation of the cellular mechanical features to regulate metabolic function. This important relationship between mechanical properties and function has until now been underexplored in artificial cell research. Here, we have created an artificial cell platform that exploits internal supramolecular interactions to display viscoadaptive behavior.

Background: Apolipoprotein E (APOE)-ε4 allele is associated with cognitive decline; however, its potential to modify effects of vitamin D3 and omega-3s supplementation on later-life cognition is unclear. Our objectives were to estimate among the in-clinic subset of a randomized trial: (1) associations between APOE-ε4 and global and domain-specific cognitive change, with exploration of potential sex and race differences; and (2) modification by APOE-ε4 of effects of vitamin D3 and omega-3s supplementation on cognitive change.

Methods: From an ancillary study of depression prevention within a completed 2 × 2 factorial trial testing vitamin D3 (2 000 IU per day), omega-3s (1 g per day), and/or placebos, we included 743 older adults with baseline in-person neuropsychiatric assessments and APOE genotyping data.
