The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

open access: yes, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

open access: yesFEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

In Vitro Host-Cell Susceptibility to Usutu Virus

open access: yesEmerging Infectious Diseases, 2005
We investigated the susceptibility to Usutu virus (Flavivirus) of 13 permanent cell lines, 3 primary cell cultures, and chicken embryos. Vero, PK-15, and goose embryo fibroblast cells developed cytopathic effects; however, viral multiplication was ...

Trophoblast lineage specification in the mammalian preimplantation embryo

open access: yesReproductive Medicine and Biology, 2020
Background The establishment of the trophectoderm (TE) and the inner cell mass (ICM) is the first cell lineage segregation that occurs in mammalian preimplantation development. TE will contribute to the placenta while ICM cells give rise to the epiblast (

Synthesis of spectrin in avian erythroid cells: association of nascent polypeptide chains with the cytoskeleton [PDF]

open access: yes, 1983
The site of synthesis of spectrin was investigated in erythroid cells from 10-day chicken embryos. After various periods of [35S]methionine incorporation the cells were lysed in a Triton X-100 (TX-100)-containing buffer and were separated into a TX-100 ...

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition

open access: yesFEBS Open Bio, EarlyView.
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

The Wnt/TCF7L1 transcriptional repressor axis drives primitive endoderm formation by antagonizing naive and formative pluripotency

open access: yesNature Communications, 2023
Signal transduction and gene expression regulation via downstream transcription factors shape the early mammalian embryo. Here the authors show that Wnt/TCF7L1 transcriptional repressive activity is required for primitive endoderm lineage formation.
