Unraveling the complexity of thermogenic remodeling of white fat reveals potential antiobesity therapies.

Genes & development

Rabhi N, Farmer SR.
PMID: 34725126
Genes Dev. 2021 Nov 01;35(21):1395-1397. doi: 10.1101/gad.349053.121.

Adipose tissue is a complex organ consisting of a mixture of mature adipocytes and stromal vascular cells. It displays a remarkable ability to adapt to environmental and dietary cues by changing its morphology and metabolic capacity. This plasticity is...

Opening the window for endothelial-to-hematopoietic transition.

Genes & development

Samarakkody AS, Cantor AB.
PMID: 34725127
Genes Dev. 2021 Nov 01;35(21):1398-1400. doi: 10.1101/gad.349056.121.

Definitive long-term hematopoietic stem cells (LT-HSCs) arise during embryogenesis in a process termed endothelial-to-hematopoietic transition (EHT), in which specialized hemogenic endothelial cells (HECs) transform into hematopoietic cells. The transcription factor RUNX1 marks HECs and is essential for EHT. Ectopic

REST is a major negative regulator of endocrine differentiation during pancreas organogenesis.

Genes & development

Rovira M, Atla G, Maestro MA, Grau V, García-Hurtado J, Maqueda M, Mosquera JL, Yamada Y, Kerr-Conte J, Pattou F, Ferrer J.
PMID: 34385258
Genes Dev. 2021 Sep 01;35(17):1229-1242. doi: 10.1101/gad.348501.121. Epub 2021 Aug 12.

Multiple transcription factors have been shown to promote pancreatic β-cell differentiation, yet much less is known about negative regulators. Earlier epigenomic studies suggested that the transcriptional repressor REST could be a suppressor of endocrinogenesis in the embryonic pancreas. However,...

Discovery of ciliary G protein-coupled receptors regulating pancreatic islet insulin and glucagon secretion.

Genes & development

Wu CT, Hilgendorf KI, Bevacqua RJ, Hang Y, Demeter J, Kim SK, Jackson PK.
PMID: 34385262
Genes Dev. 2021 Sep 01;35(17):1243-1255. doi: 10.1101/gad.348261.121. Epub 2021 Aug 12.

Multiple G protein-coupled receptors (GPCRs) are expressed in pancreatic islet cells, but the majority have unknown functions. We observed specific GPCRs localized to primary cilia, a prominent signaling organelle, in pancreatic α and β cells. Loss of cilia disrupts...

Replication protein A associates with nucleolar R loops and regulates rRNA transcription and nucleolar morphology.

Genes & development

Feng S, Manley JL.
PMID: 34819354
Genes Dev. 2021 Dec 01;35(23):1579-1594. doi: 10.1101/gad.348858.121. Epub 2021 Nov 24.

The nucleolus is an important cellular compartment in which ribosomal RNAs (rRNAs) are transcribed and where certain stress pathways that are crucial for cell growth are coordinated. Here we report novel functions of the DNA replication and repair factor...

Corrigendum: Differential requirements for MDM2 E3 activity during embryogenesis and in adult mice.

Integrated loss- and gain-of-function screens define a core network governing human embryonic stem cell behavior.

Genes & development

Naxerova K, Di Stefano B, Makofske JL, Watson EV, de Kort MA, Martin TD, Dezfulian M, Ricken D, Wooten EC, Kuroda MI, Hochedlinger K, Elledge SJ.
PMID: 34711655
Genes Dev. 2021 Nov 01;35(21):1527-1547. doi: 10.1101/gad.349048.121. Epub 2021 Oct 28.

Understanding the genetic control of human embryonic stem cell function is foundational for developmental biology and regenerative medicine. Here we describe an integrated genome-scale loss- and gain-of-function screening approach to identify genetic networks governing embryonic stem cell proliferation and...

The Zip4 protein directly couples meiotic crossover formation to synaptonemal complex assembly.

Genes & development

Pyatnitskaya A, Andreani J, Guérois R, De Muyt A, Borde V.
PMID: 34969823
Genes Dev. 2021 Dec 30; doi: 10.1101/gad.348973.121. Epub 2021 Dec 30.

Meiotic recombination is triggered by programmed double-strand breaks (DSBs), a subset of these being repaired as crossovers, promoted by eight evolutionarily conserved proteins, named ZMM. Crossover formation is functionally linked to synaptonemal complex (SC) assembly between homologous chromosomes, but...

Efficient hemogenic endothelial cell specification by RUNX1 is dependent on baseline chromatin accessibility of RUNX1-regulated TGFβ target genes.

Genes & development

Howell ED, Yzaguirre AD, Gao P, Lis R, He B, Lakadamyali M, Rafii S, Tan K, Speck NA.
PMID: 34675061
Genes Dev. 2021 Nov 01;35(21):1475-1489. doi: 10.1101/gad.348738.121. Epub 2021 Oct 21.

Hematopoietic stem and progenitor cells (HSPCs) are generated de novo in the embryo from hemogenic endothelial cells (HECs) via an endothelial-to-hematopoietic transition (EHT) that requires the transcription factor RUNX1. Ectopic expression of RUNX1 alone can efficiently promote EHT and...

Disruption of origin chromatin structure by helicase activation in the absence of DNA replication.

Genes & development

Hoffman RA, MacAlpine HK, MacAlpine DM.
PMID: 34556529

Prior to initiation of DNA replication, the eukaryotic helicase, Mcm2-7, must be activated to unwind DNA at replication start sites in early S phase. To study helicase activation within origin chromatin, we constructed a conditional mutant of the polymerase...

Dynamics in Fip1 regulate eukaryotic mRNA 3' end processing.

Cleavage and polyadenylation factor (CPF/CPSF) is a multiprotein complex essential for mRNA 3' end processing in eukaryotes. It contains an endonuclease that cleaves pre-mRNAs, and a polymerase that adds a poly(A) tail onto the cleaved 3' end. Several CPF...
