Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]

, 2015
Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (

Valores séricos de imunoglobulinas e dos componentes do complemento em gestantes com ruptura prematura de membranas Immunoglobulin serum values and complement components in pregnant women with premature rupture of the membranes

Revista Brasileira de Ginecologia e Obstetrícia, 2007
OBJETIVO: a ruptura prematura de membranas (RPM) tem sido motivo para muitas indagações, dentre as quais os mecanismos imunes envolvidos. Diante da escassez de estudos relacionados ao tema, este trabalho teve como objetivo avaliar os valores séricos de ...

Integrin-Dependent Apposition of Drosophila Extraembryonic Membranes Promotes Morphogenesis and Prevents Anoikis [PDF]

Current Biology, 2004
Two extraembryonic tissues form early in Drosophila development. One, the amnioserosa, has been implicated in the morphogenetic processes of germ band retraction and dorsal closure. The developmental role of the other, the yolk sac, is obscure.By using live-imaging techniques, we report intimate interactions between the amnioserosa and the yolk sac ...

Distribution of O-Acetylated Sialic Acids among Target Host Tissues for Influenza Virus. [PDF]

, 2017
Sialic acids (Sias) are important glycans displayed on the cells and tissues of many different animals and are frequent targets for binding and modification by pathogens, including influenza viruses.

Development of the Human Placenta and Fetal Heart: Synergic or Independent?

Frontiers in Physiology, 2018
The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output.

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

Targeted Deletion in the Basal Body Protein Talpid3 Leads to Loss of Primary Cilia in Embryonic Stem Cells and Defective Lineage-Specific Differentiation

Cells
Talpid3 is a basal body protein required for the formation of primary cilia, an organelle involved in signal transduction. Here, we asked if Talpid3 has a role in the regulation of differentiation and/or self-renewal of ES cells and whether cells lacking

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.
