The Axial Organ and the Pharynx Are Sites of Hematopoiesis in the Sea Urchin

open access: yesFrontiers in Immunology, 2019
Background: The location of coelomocyte proliferation in adult sea urchins is unknown and speculations since the early 1800s have been based on microanatomy and tracer uptake studies.

Role of CYP eicosanoids in the regulation of pharyngeal pumping and food uptake in Caenorhabditis elegans[S]

open access: yesJournal of Lipid Research, 2015
Cytochrome P450 (CYP)-dependent eicosanoids comprise epoxy- and hydroxy-metabolites of long-chain PUFAs (LC-PUFAs). In mammals, CYP eicosanoids contribute to the regulation of cardiovascular and renal function. Caenorhabditis elegans produces a large set

Pharyngeal-Esophageal Malignancies with Dermatologic Paraneoplastic Syndrome

open access: yesLife, 2022
Systemic changes often send signals to the skin, and certain neoplastic diseases of the internal organs can also trigger skin manifestations. In this article, the authors make clinical photography presentations of the patients seen at our clinic with ...

Cas9-mediated excision of Nematostella brachyury disrupts endoderm development, pharynx formation and oral-aboral patterning

open access: yesDevelopment, 2017
The mesoderm is a key novelty in animal evolution, although we understand little of how the mesoderm arose. brachyury, the founding member of the T-box gene family, is a key gene in chordate mesoderm development.

Molecular and Cellular Organization of Taste Neurons in Adult Drosophila Pharynx.

open access: yesCell Reports, 2017
The Drosophila pharyngeal taste organs are poorly characterized despite their location at important sites for monitoring food quality. Functional analysis of pharyngeal neurons has been hindered by the paucity of molecular tools to manipulate them, as ...
