Vertebrate embryonic development relies on tightly regulated signaling pathways that guide morphogenesis, cell fate specification, and tissue organization. Among these, the Wnt signaling pathway plays a central role, orchestrating key developmental e...
Female gametogenesis is orchestrated by dynamic epigenetic modifications. In mammals, SETDB1, a histone H3K9 methyltransferase, is required for proper meiotic progression and early embryonic development. In Drosophila, the ortholog of SETDB1 plays a...
Glucagon-like peptide 1 (GLP-1), a hormone derived from the proglucagon gene, regulates various physiological processes; however, its impact on pregnancy outcomes remains poorly understood. Assessing the effects of GLP-1 on neonates is vital as GLP-1...
The development process of the heart and cardiovascular system is fundamental in human development and highly regulated by genetic factors. This process needs to be highly regulated to prevent malformations. Nevertheless, some heart defects may be id...
The stomach has been a highly conserved organ throughout vertebrate evolution; however, there are now over 20 lineages composed of monotremes, lungfish and teleost fish displaying a secondary loss of stomach function and morphology. This “agast...
Craniofacial development is a complex, highly conserved process involving multiple tissue types and molecular pathways, with perturbations resulting in congenital defects that often require invasive surgical interventions to correct. Remarkably, some...
