Liu, Nie et al. identify disulfidptosis as a form of cell death resulting from aberrant accumulation of disulfide bonds in actin cytoskeleton proteins that is induced following glucose starvation and dependent on SLC7A11-mediated cystine uptake.
An ependymoma subtype is driven by fusion proteins related to the transcriptional regulator YAP1. Research now shows that localization of these fusion proteins within nuclear condensates is necessary and sufficient for tumour formation through the activation of various genetic and epigenetic oncogenic mechanisms.
Lotfollahi et al. present ExpiMap, a deep-learning model enabling interpretable reference mapping of RNA sequencing data using biologically defined entities, offering end-to-end analysis from dataset integration to functional interpretation.
Harasimov et al. show that, in human and porcine oocytes, actin cables and microtubule loops move chromosomes into a cluster before spindle assembly to ensure fast and complete chromosome capture in meiosis.
Hu et al. report that patient-derived YAP fusion proteins undergo liquid–liquid phase separation in the nucleus to drive ependymoma tumourigenesis, altering transcription through transcription factor recruitment and alteration of genomic methylation.
Daylon James is an associate professor at Weill Cornell Medicine in New York, where his work focuses on reproductive biology and cell-based approaches for treating infertility. Arun Sharma is an assistant professor at the Cedars-Sinai Medical Center Regenerative Medicine Institute, and his lab works on modelling cardiovascular diseases and developing cell-based screening platforms for drug toxicity. Many of us also know them as the hosts of the Stem Cell Podcast. Here, we ask them about the podcast and discuss their view on the stem cell field and science communication.
Contraction of the hair follicle-lining dermal sheath smooth muscle generates the forces necessary for the tissue remodelling that takes place during the regression phase of the hair growth cycle. This study reveals that endothelin signalling — from epithelial progenitors at the follicle bottleneck region to its neighbouring dermal sheath — is the main contraction-activating pathway.
Huebner et al. develop a 2D culture system to study gastric isthmus stem cells and identify a role for Sox2 in specifying enterochromaffin cells in the stomach.
Martino, Sunkara et al. report that endothelin produced by hair follicle progenitors binds to endothelin receptors on dermal sheath cells to trigger their contraction and hair follicle regression.
Kara McKinley is an assistant professor of stem-cell and regenerative biology at Harvard University. In addition to advancing our understanding of endometrial regeneration, she has tackled the gender bias in the academic job market by founding the ‘Leading Edge Fellows’ program. Nature Cell Biology contacted her to discuss her career and goals for our research community.
The Institute of Molecular and Cell Biology (IMCB) in Singapore has helped the local scientific community to grow. Nature Cell Biology spoke to Wanjin Hong (executive director at A*STAR’s IMCB) and Guillaume Thibault (associate professor affiliated with Nanyang Technological University Singapore, National University of Singapore and A*STAR’s IMCB), who have dedicated parts of their careers to the growth of cell biology research in Singapore, about the history and directions of cell biological research programs in Singapore.
Wong et al. report that expanding human embryonic stem cell-derived endodermal progenitors serve as a ventral foregut model, through which they identify a link between progenitor expansion and tissue-specific changes in the enhancer landscape.
Adriaenssens et al. provide evidence suggesting that cytosolic small heat shock proteins localize to the mitochondrial intermembrane space, where they operate as molecular chaperones.
Extramitochondrial coenzyme Q (CoQ) can function as a potent anti-ferroptosis radical trapper. However, it is largely unknown how CoQ is transported from mitochondria to the plasma membrane. A study now suggests that PARL-mediated STARD7 processing is responsible for the cellular distribution of CoQ.
Tight regulation of the activity of EWS–ETS fusion proteins is essential for the growth of Ewing sarcomas. Two new studies show that the transcriptional repressor ETV6 is essential for tumour growth, acting to restrain fusion-protein-mediated gene activation, and revealing the importance of tissue-specific transcription factors to oncogenesis.
Alternative splicing of eukaryotic messenger RNA transcripts often leads to the production of several mature RNAs — including linear RNAs and circular RNAs (circRNAs) — from a single gene locus. The names given to circRNAs are often ambiguous and lack consistency across studies. This Comment calls on the community to embrace a common nomenclature for naming circRNAs to ensure clarity and reproducibility.
Independent but complementary studies from Vakoc and Stegmaier identify and characterize a role for ETV6 in counteracting the transcriptional activity of EWS–FLI during Ewing sarcoma development, which may be targeted for therapeutic benefits.
Deshwal et al. show that the protease PARL regulates coenzyme Q (CoQ) via the lipid transfer protein STARD7. Mitochondrial STARD7 ensures CoQ synthesis; cytosolic STARD7 preserves CoQ transport to the membrane, protecting cells against ferroptosis.
