Unfolded protein-independent IRE1 activation contributes to multifaceted developmental processes in ArabidopsisThe Arabidopsis unfolded protein response transducer IRE1 contributes to male gametophyte development using an alternative activation mechanism bypassing the unfolded protein-sensing domain.
Endogenous epitope-tagging of Tet1, Tet2 and Tet3 identifies TET2 as a naïve pluripotency markerExpression of TET proteins in pluripotent cell types is visualised by epitope tagging of endogenous alleles.
Mutagenesis of the ADAM17-phosphatidylserine–binding motif leads to embryonic lethality in miceMutation of three cationic amino acids previously identified as an extracellular phosphatidylserine-binding motif abrogates ADAM17 sheddase function and causes early embryonic death in mice.
The miRNA bantam regulates growth and tumorigenesis by repressing the cell cycle regulator tribblesThis work identifies the cell cycle regulator tribbles as a target of the miRNA bantam involved in the growth regulatory and oncogenic functions of bantam in Drosophila epithelia.
Opposing functions of F-BAR proteins in neuronal membrane protrusion, tubule formation, and neurite outgrowthNeurite formation is a fundamental antecedent to axon and dendrite formation, but the mechanisms that underlie this important process are poorly characterized. Here, we demonstrate that two F-BAR proteins, CIP4 and FBP17, have opposing functions in early cortical neuron development.
The hypoxia-response pathway modulates RAS/MAPK–mediated cell fate decisions in Caenorhabditis elegansAtmospheric oxygen levels modulate the RAS/MAPK signaling pathway in the nematode Caenorhabditis elegans through a cross-talk between the DELTA/NOTCH and hypoxia signaling pathways. These mechanisms may permit the animals to adapt their development to changes in the environment.
CXXC5 mediates growth plate senescence and is a target for enhancement of longitudinal bone growthInhibition of the CXXC5–DVL interaction is a potential therapeutic strategy for height enhancement of children with growth retardation.
ROS amplification drives mouse spermatogonial stem cell self-renewalAlthough reactive oxygen species (ROS) are required for spermatogonial stem cell (SSC) self-renewal, the mechanism has remained unknown. We show that SSC self-renewal signals activate MAPK14/MAPK7 pathway to induce nuclear translocation of BCL6B and activation of NOX1.
Intra-individual methylomics detects the impact of early-life adversityThis study shows that methylation profile changes across time in the same individual distinguish a stressful experience from typical infancy, providing a potential predictive marker of vulnerability to disease.
Sequence and expression levels of circular RNAs in progenitor cell types during mouse corticogenesisThis study identifies circular RNAs (circRNAs) in specific cell types of the developing mammalian cortex. This resource addresses the complexity and potential significance of this elusive class of transcripts.
