Pleiotropic effects of a methyl donor diet in a novel animal model. [PDF]
PLoS ONE, 2014 Folate and other methyl-donor pathway components are widely supplemented due to their ability to prevent prenatal neural tube defects. Several lines of evidence suggest that these supplements act through epigenetic mechanisms (e.g.

Understanding pseudo-albinism in sole (Solea senegalensis): a transcriptomics and metagenomics approach [PDF]
, 2019 Pseudo-albinism is a pigmentation disorder observed in flatfish aquaculture with a complex, multi-factor aetiology. We tested the hypothesis that pigmentation abnormalities are an overt signal of more generalised modifications in tissue structure and ...

Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, EarlyView.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Developmental Dynamics, EarlyView.Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Structural and Molecular Evolutionary Analysis of Agouti and Agouti-Related Proteins
Chemistry & Biology, 2006 Agouti (ASIP) and Agouti-related protein (AgRP) are endogenous antagonists of melanocortin receptors that play critical roles in the regulation of pigmentation and energy balance, respectively, and which arose from a common ancestral gene early in vertebrate evolution.

Regulation of leptin by agouti [PDF]
Physiological Genomics, 2000 Claycombe, Kate J., Bing Zhong Xue, Randall L. Mynatt, Michael B. Zemel, and Naïma Moustaïd-Moussa. Regulation of leptin by agouti. Physiol Genomics 2: 101–105, 2000.—Dominant mutations at the mouse Agouti locus lead to ectopic expression of the Agouti gene and exhibit diabetes, obesity, and yellow coat color. Obese yellow mice are hyperinsulinemic and

Pediatric Investigation, EarlyView.Monogenic and syndromic obesity in children often arises from defects in the leptin–melanocortin pathway. Understanding these rare genetic causes not only clarifies mechanisms of appetite regulation but also enables precision therapies, offering hope beyond lifestyle interventions.

Wildlife Biology, EarlyView.With urbanization reducing the amount of available wildlife habitat, and outdoor recreation increasing the human activity within wildlife habitats, it is important to understand the effects of human activity on animal behavior. This study examined how the reduction in human presence in urban parks in Gainesville, Florida, affected the temporal ...
