Maternal and Embryonic Stress Influence Offspring Behavior in the Cuttlefish Sepia officinalis
Frontiers in Physiology, 2017 Stress experienced during prenatal development—either applied to reproducing females (maternal stress), directly to developing offspring (embryonic stress) or in combination—is associated with a range of post-natal behavioral effects in numerous ...

ERK1/2 is an ancestral organising signal in spiral cleavage
Nature Communications, 2022 How invertebrates with spiral cleavage establish their body plans is unclear. Here the authors show that, like molluscs, a basal annelid uses ERK1/2 to instruct body patterning, suggesting that this is a deep ancestral trait in animal embryogenesis.

Frontiers in Cell and Developmental Biology, 2022 Specification and elaboration of proximo-distal (P-D) axes for structures or tissues within a body occurs secondarily from that of the main axes of the body. Our understanding of the mechanism(s) that pattern P-D axes is limited to a few examples such as

The social patterning of relative body weight and obesity in Denmark and Finland [PDF]
, 2006 Udgivelsesdato: 2006-FebBACKGROUND: Relative body weight is typically inversely associated with social status in affluent societies but studies comparing the social patterning of relative body weight and obesity in different countries have only seldom ...

Frontiers in Physiology, 2021 The speed of adaptive body patterning in coleoid cephalopods is unmatched in the natural world. While the literature frequently reports their remarkable ability to change coloration significantly faster than other species, there is limited research on ...

Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]
, 2007 Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Waves and patterning in developmental biology: vertebrate segmentation and feather bud formation as case studies [PDF]
, 2009 In this article we will discuss the integration of developmental patterning mechanisms with waves of competency that control the ability of a homogeneous field of cells to react to pattern forming cues and generate spatially heterogeneous patterns.

Anterior-posterior gene expression differences in three Lake Malawi cichlid fishes with variation in body stripe orientation [PDF]
PeerJ, 2017 Morphological differentiation among closely related species provides opportunities to study mechanisms shaping natural phenotypic variation. Here, we address variation in the orientation of melanin-colored body stripes in three cichlid species of the ...

Auxin-dependent cell cycle reactivation through transcriptional regulation of Arabidopsis E2Fa by lateral organ boundary proteins [PDF]
, 2011 Multicellular organisms depend on cell production, cell fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example

Regulating Retinoic Acid Availability during Development and Regeneration: The Role of the CYP26 Enzymes. [PDF]
, 2020 This review focuses on the role of the Cytochrome p450 subfamily 26 (CYP26) retinoic acid (RA) degrading enzymes during development and regeneration. Cyp26 enzymes, along with retinoic acid synthesising enzymes, are absolutely required for RA homeostasis
