Deletion of Tet proteins results in quantitative disparities during ESC differentiation partially attributable to alterations in gene expression. BMC Dev. Biol. (IF 1.978) Pub Date : 2019-07-08 Michael Reimer,Kirthi Pulakanti,Linzheng Shi,Alex Abel,Mingyu Liang,Subramaniam Malarkannan,Sridhar Rao
BACKGROUND The Tet protein family (Tet1, Tet2, and Tet3) regulate DNA methylation through conversion of 5-methylcytosine to 5-hydroxymethylcytosine which can ultimately result in DNA demethylation and play a critical role during early mammalian development and pluripotency. While multiple groups have generated knockouts combining loss of different Tet proteins in murine embryonic stem cells (ESCs)

Importance of prostate androgen-regulated mucin-like protein 1 in development of the bovine blastocyst. BMC Dev. Biol. (IF 1.978) Pub Date : 2019-07-05 Adriana M Zolini,Verónica M Negrón-Pérez,Peter J Hansen
BACKGROUND Prostate androgen-regulated mucin-like protein 1 (PARM1) is a pro-proliferative and anti-apoptotic glycoprotein involved in the endoplasmic reticulum (ER) stress response. A single nucleotide polymorphism in the coding region of PARM1 has been associated with competence of bovine embryos to develop to the blastocyst stage. Here we tested the importance of PARM1 for development by evaluating

A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos. BMC Dev. Biol. (IF 1.978) Pub Date : 2019-07-04 Jesica R Canizo,Amada E Ynsaurralde Rivolta,Camila Vazquez Echegaray,Mariana Suvá,Virgilia Alberio,Juan F Aller,Alejandra S Guberman,Daniel F Salamone,Ricardo H Alberio,Ramiro Alberio
BACKGROUND The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been partially studied, and evidence shows that MEK signalling plays a limited role in the segregation of this lineage. Here we explored the role of different signalling pathways during lineage

An annual cycle of gene regulation in the red-legged salamander mental gland: from hypertrophy to expression of rapidly evolving pheromones. BMC Dev. Biol. (IF 1.978) Pub Date : 2019-04-27 Damien B Wilburn,Richard C Feldhoff
BACKGROUND Cell differentiation is mediated by synchronized waves of coordinated expression for hundreds to thousands of genes, and must be regulated to produce complex tissues and phenotypes. For many animal species, sexual selection has driven the development of elaborate male ornaments, requiring sex-specific differentiation pathways. One such male ornament is the pheromone-producing mental gland
