Extracellular matrix mediates moruloid-blastuloid morphodynamics in malignant ovarian spheroidsExpression dynamics of basement membrane-like extracellular matrix and fibronectin regulate transitions between solid (moruloid) and cavitational (blastuloid) phenotypes of ovarian cancer spheroids.
Asymmetrical deposition and modification of histone H3 variants are essential for zygote developmentA low level of H3.1/2 deposition in the perinucleolar regions of male pronuclei in zygotes prevents accumulation of H3.1/2K27me3 modification which has detrimental effect on DNA replication.
Edem1 activity in the fat body regulates insulin signalling and metabolic homeostasis in DrosophilaEdem1, an endoplasmic reticulum-resident protein, acts in the fat body to regulate insulin signalling and metabolic status in Drosophila, which aids in survival against nutrient deprivation.
In utero exposure to chlordecone affects histone modifications and activates LINE-1 in cord bloodIn utero exposure to chlordecone affects chromatin and leads to activation of retroelements. This study shows the changes induced by chlordecone in human umbilical cord blood and blood-derived cell line.
GATA transcription factors, SOX17 and TFAP2C, drive the human germ-cell specification programThis work shows that GATA transcription factors transduce the BMP signaling and, with SOX17 and TFAP2C, induce the human germ-cell fate, delineating the mechanism for human germ-cell specification.
Different mutant RUNX1 oncoproteins program alternate haematopoietic differentiation trajectoriesUsing integrated genome-wide and phenotypic methods this study investigates four different mutant RUNX1 oncoproteins and reveals how they differentially contribute to aberrant haematopoiesis.
Modulation of Aub–TDRD interactions elucidates piRNA amplification and germplasm formationN-terminal Aub arginines are dispensable for primary piRNA biogenesis but essential for amplification; their symmetric dimethylation is required for germline inheritance but not for piRNA amplification.
Inhibition of a transcriptional repressor rescues hearing in a splicing factor–deficient mouseThe vital role of the splicing factor SRRM4 in vestibular and inner hair cells of the ear is inactivation of the gene repressor REST; however, in outer hair cells, SRRM4 is dispensable for REST inactivation, which SRRM3 accomplishes independently.
MicroRNA regulation of murine trophoblast stem cell self-renewal and differentiationPost-transcriptional regulation of CDX2 and cell cycle genes by miR-290 and miR-322 clusters along with transactivation of miR-290 cluster and cyclin D1 by CDX2 equipoise trophoblast stem cell self-renewal and differentiation.
Robust production of uniform human cerebral organoids from pluripotent stem cellsBy leveraging advances in 3D stem cell culture techniques, the authors describe, characterize and validate a novel platform to efficiently generate morphologically consistent human forebrain cerebral organoids.
