Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

Developmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Deep sequencing and expression of microRNAs from early honeybee (Apis mellifera) embryos reveals a role in regulating early embryonic patterning

BMC Evolutionary Biology, 2012
Background Recent evidence supports the proposal that the observed diversity of animal body plans has been produced through alterations to the complexity of the regulatory genome rather than increases in the protein-coding content of a genome.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Embryotoxic Effects of Monosodium Methyl Arsenate (MSMA) on Gallus gallus: Morphological and Morphometric Evidence of Developmental Disruptions

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.

Cell lineage specific distribution of H3K27 trimethylation accumulation in an in vitro model for human implantation [PDF]

, 2012
Female mammals inactivate one of their two X-chromosomes to compensate for the difference in gene-dosage with males that have just one X-chromosome. X-chromosome inactivation is initiated by the expression of the non-coding RNA Xist, which coats the X ...

BRD9 inhibition as potential treatment option for testicular germ cell tumors

Andrology, EarlyView.
Abstract Background Testicular germ cell tumors (TGCT) are the predominant tumor in younger males. Usually, 5‐year survival rates are quite high, but 15–20% of patients with metastatic non‐seminomas are resistant to standard cisplatin‐based therapy.

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-
