(IF 28.824) Pub Date : 2022-04-21 Yi Liu, Zhe Chen, Zong-Heng Wang, Katherine M. Delaney, Juanjie Tang, Mehdi Pirooznia, Duck-Yeon Lee, Ilker Tunc, Yuesheng Li, Hong Xu
Mitochondrial DNA (mtDNA) replication and transcription are of paramount importance to cellular energy metabolism. Mitochondrial RNA polymerase is thought to be the primase for mtDNA replication. However, it is unclear how this enzyme, which normally transcribes long polycistronic RNAs, can produce short RNA oligonucleotides to initiate mtDNA replication. We show that the PPR domain of Drosophila mitochondrial

A feedback loop engaging propionate catabolism intermediates controls mitochondrial morphology Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-13 Junxiang Zhou, Mei Duan, Xin Wang, Fengxia Zhang, Hejiang Zhou, Tengfei Ma, Qiuyuan Yin, Jie Zhang, Fei Tian, Guodong Wang, Chonglin Yang
d-2-Hydroxyglutarate (D-2HG) is an α-ketoglutarate-derived mitochondrial metabolite that causes d-2-hydroxyglutaric aciduria, a devastating developmental disorder. How D-2HG adversely affects mitochondria is largely unknown. Here, we report that in Caenorhabditis elegans, loss of the D-2HG dehydrogenase DHGD-1 causes D-2HG accumulation and mitochondrial damage. The excess D-2HG leads to a build-up

CellComm infers cellular crosstalk that drives haematopoietic stem and progenitor cell development Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-12 Edroaldo Lummertz da Rocha, Caroline Kubaczka, Wade W. Sugden, Mohamad Ali Najia, Ran Jing, Arianna Markel, Zachary C. LeBlanc, Rafael dos Santos Peixoto, Marcelo Falchetti, James J. Collins, Trista E. North, George Q. Daley
Intercellular communication orchestrates a multitude of physiologic and pathologic conditions. Algorithms to infer cell–cell communication and predict downstream signalling and regulatory networks are needed to illuminate mechanisms of stem cell differentiation and tissue development. Here, to fill this gap, we developed and applied CellComm to investigate how the aorta–gonad–mesonephros microenvironment

Stem cell conversion to the cardiac lineage requires nucleotide signalling from apoptosing cells Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-12 Loic Fort, Vivian Gama, Ian G. Macara
Pluripotent stem cells can be driven by manipulation of Wnt signalling through a series of states similar to those that occur during early embryonic development, transitioning from an epithelial phenotype into the cardiogenic-mesoderm lineage and ultimately into functional cardiomyocytes. Strikingly, we observed that initiation of differentiation in induced pluripotent stem cells (iPSCs) and embryonic

Multiplexed genome regulation in vivo with hyper-efficient Cas12a Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-12 Lucie Y. Guo, Jing Bian, Alexander E. Davis, Pingting Liu, Hannah R. Kempton, Xiaowei Zhang, Augustine Chemparathy, Baokun Gu, Xueqiu Lin, Draven A. Rane, Xiaoshu Xu, Ryan M. Jamiolkowski, Yang Hu, Sui Wang, Lei S. Qi
Multiplexed modulation of endogenous genes is crucial for sophisticated gene therapy and cell engineering. CRISPR–Cas12a systems enable versatile multiple-genomic-loci targeting by processing numerous CRISPR RNAs (crRNAs) from a single transcript; however, their low efficiency has hindered in vivo applications. Through structure-guided protein engineering, we developed a hyper-efficient Lachnospiraceae

Exploring the expanding universe of small RNAs Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-12 Junchao Shi, Tong Zhou, Qi Chen
The world of small noncoding RNAs (sncRNAs) is ever-expanding, from small interfering RNA, microRNA and Piwi-interacting RNA to the recently emerging non-canonical sncRNAs derived from longer structured RNAs (for example, transfer, ribosomal, Y, small nucleolar, small nuclear and vault RNAs), showing distinct biogenesis and functional principles. Here we discuss recent tools for sncRNA identification

Centrosomes grow aggresomes to clear waste Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-11 Elisa Vitiello, Fanni Gergely
Overload of proteasomal clearance triggers formation of a large protein inclusion called the aggresome, which shares similarities with protein aggregates seen in neurodegenerative diseases such as Huntington’s. A new study uncovers how centrosome and centriolar satellite components facilitate stepwise assembly of aggresomes.

Unchecked oxidative stress in skeletal muscle prevents outgrowth of disseminated tumour cells Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-11 Sarah B. Crist, Travis Nemkov, Ruth F. Dumpit, Jinxiang Dai, Stephen J. Tapscott, Lawrence D. True, Alexander Swarbrick, Lucas B. Sullivan, Peter S. Nelson, Kirk C. Hansen, Cyrus M. Ghajar
Skeletal muscle has long been recognized as an inhospitable site for disseminated tumour cells (DTCs). Yet its antimetastatic nature has eluded a thorough mechanistic examination. Here, we show that DTCs traffic to and persist within skeletal muscle in mice and in humans, which raises the question of how this tissue suppresses colonization. Results from mouse and organotypic culture models along with

Epithelial–mesenchymal transition (EMT) programs operate within carcinoma cells, where they generate phenotypes associated with malignant progression. In their various manifestations, EMT programs enable epithelial cells to enter into a series of intermediate states arrayed along the E–M phenotypic spectrum. At present, we lack a coherent understanding of how carcinoma cells control their entrance

Membrane surfaces regulate assembly of ribonucleoprotein condensates Nat. Cell Biol. (IF 28.824) Pub Date : 2022-04-11 Wilton T. Snead, Ameya P. Jalihal, Therese M. Gerbich, Ian Seim, Zhongxiu Hu, Amy S. Gladfelter
Biomolecular condensates organize biochemistry, yet little is known about how cells control the position and scale of these structures. In cells, condensates often appear as relatively small assemblies that do not coarsen into a single droplet despite their propensity to fuse. Here, we report that ribonucleoprotein condensates of the glutamine-rich protein Whi3 interact with the endoplasmic reticulum
