Background Puberty is a highly heritable and variable trait, with environmental factors having a role in its eventual timing and development. Early and late pubertal onset are both associated with various diseases developing later in life, and epigenetic c ...
This study reports the expression domains of two murine HOX gene members of the HOX-5 complex (Hox-5.2, Hox-5.3). These two genes have very similar homeodomain sequences, as well as temporal and spatial specificities of expression. They are both expressed ...
Wnt/beta-catenin and NF-kappaB signaling mechanisms provide central controls in development and disease, but how these pathways intersect is unclear. Using hair follicle induction as a model system, we show that patterning of dermal Wnt/beta-catenin signal ...
Some sacoglossan sea slugs incorporate intracellular functional algal chloroplasts, a process termed kleptoplasty. "Stolen" chloroplasts (kleptoplasts) can remain photosynthetically active up to several months, contributing to animal nutrition. Whether thi ...
The glucocorticoid-induced leucine zipper (Tsc22d3-2) is a widely expressed dexamethasone-induced transcript that has been proposed to be important in immunity, adipogenesis, and renal sodium handling based on in vitro studies. To address its function in v ...
During spermatogenesis, postmeiotic germ cells utilize lactate produced by Sertoli cells as an energy metabolite. While the hormonal regulation of lactate production in Sertoli cells has been relatively well established, the transport of this energy substr ...
Fish populations can be threatened by distorted sex ratios that arise during sex differentiation. Here we describe sex differentiation in a wild grayling (Thymallus thymallus) population that suffers from distorted sex ratios. We verified that sex determin ...
