Chromatin heterogeneity in the trailing nuclear half creates a permissive environment for condensate formation, with potential roles in nuclear mechanics and chromatin interactions.

Obesity-induced transcriptional and epigenetic alterations persist following weight loss, which negatively affects adipose tissue function and increases the propensity to regain weight.

This year marks the 30th anniversary of the publication of a novel approach to measuring protein–protein interactions (PPIs) in living cells, called the ubiquitin-based split-protein sensor (USPS), the inspiration for the protein-fragment complementation assays (PCAs) that followed. Here I provide a brief history of PCAs and discuss advances in their applications and possible future developments. Stephen

The cellular environment is critical to protein function. How is information from many cellular components decoded in order to fine-tune biological activity? New models of biomolecular recognition raise the possibility that proteins engage in specific, yet fuzzy, interactions with their functional partners, which can provide a readout mechanism of the cellular context. Manipulating the cellular context

In this Tools of the Trade article, Cao (Baskin lab) discusses the development of MARS, which enables mitosis-specific recruitment of enzymes to the plasma membrane, exploiting the cell cycle’s natural regulation of PLEKHA5 phosphorylation.

It is now well established that ancient proteins endure, and remain informative, much longer than DNA. Accordingly, sequencing of ancient proteins is currently the only viable methodology for retrieving the genetic data required to resolve evolutionary relations between vertebrate species that disappeared millions of years ago. Ancient proteins can provide phylogenetic information at a timescale that

Tunnelling nanotubes, which are actin-based protrusions different from filopodia and cytokinetic bridges, connect cells in the zebrafish embryo, enabling the transport of proteins and organelles.

Evidence shows that RNA trafficking is a key communication mechanism across kingdoms and species, but how RNAs are secreted and trafficked and how they function within the recipient organisms remain unclear. Here, we discuss how understanding inter-organismal RNA communication can assist in disease management in both agriculture and medicine. Cross-species host–pathogen or mutualistic RNA communication

Valerie Tornini discusses two studies that identified functional roles for small proteins encoded by short open reading frames, and highlights the potential for this research field in fundamental and clinical research.

C. David Allis’s discovery of the first histone acetyltransferase from Tetrahymena exemplifies an approach that continues to evolve and now has a crucial role in drug development.

Senescent cells in the amputated head of the cnidarian Hydractinia symbiolongicarpus drive the reprogramming of somatic cells into pluripotent stem cells, which are required for full body regeneration.

Removal of different types of senescent cells can be either beneficial or detrimental to health, with potential consequences to senotherapies.

In this Tools of the Trade article, Duran (Gil lab) describes the development of novel machine learning algorithms that enable the detection of senescent cells in vitro and in diverse tissues based solely on nuclear morphologeny analysis.

James Kirkland discusses how work by Norman Sharpless and colleagues, published in 2004, paved the way for the development of senolytics, which are now in early phase clinical trials for the treatment of multiple disorders.

Raffaella Di Micco discusses the importance of a 2020 study in which CAR-T cells were engineered to eliminate senescent cells.

Ana O’Loghlen highlights a recent study that indicates that inhibiting the pro-inflammatory cytokine IL-11 has anti-ageing effects, and how such findings could have implications for the treatment of ageing-associated diseases.

Enrichment of senescent cells from organs holds great promise for studying cell senescence and ageing, and for identifying therapeutic vulnerabilities.

Akiko Takahashi discusses the seminal 1997 paper by Serrano et al. who found that oncogene activation results in a similar phenotype to replicative senescence, establishing the connection between senescence and cancer.

De Caestecker and Macara find that the sorting of membrane proteins in the Golgi relies on a size filter that enables correct localization of proteins with a short cytosolic domain to the apical membrane.

Elias Barriga discusses a seminal 2006 paper from Zhao et al., which was the first study to integrate electrotaxis signals into the established molecular framework enabling directed cell migration.

mRNAs with alternative in-frame translation initiation sites can yield proteoforms with distinct localization and functions.
