The hemodynamically-regulated vascular microenvironment promotes migration of the steroidogenic tissue during its interaction with chromaffin cells in the zebrafish embryo. [PDF]
BACKGROUND: While the endothelium-organ interaction is critical for regulating cellular behaviors during development and disease, the role of blood flow in these processes is only partially understood.

ABSTRACT Objective Managing gastrointestinal symptoms in patients with phaeochromocytoma and paraganglioma (PPGL) is challenging due to the risk of catecholaminergic crisis with many commonly prescribed medications, especially in functional tumours.

Hypoxia in the Initiation and Progression of Neuroblastoma Tumours [PDF]
Neuroblastoma is the most frequent extracranial solid tumour in children, causing 10% of all paediatric oncology deaths. It arises in the embryonic neural crest due to an uncontrolled behaviour of sympathetic nervous system progenitors, giving rise to ...

Annexin A2 Egress during Calcium-Regulated Exocytosis in Neuroendocrine Cells
Annexin A2 (AnxA2) is a calcium- and lipid-binding protein involved in neuroendocrine secretion where it participates in the formation and/or stabilization of lipid micro-domains required for structural and spatial organization of the exocytotic ...

Differentiation in neuroblastoma: diffusion-limited hypoxia induces neuro-endocrine secretory protein 55 and other markers of a chromaffin phenotype. [PDF]
Neuroblastoma is a childhood malignancy of sympathetic embryonal origin. A high potential for differentiation is a hallmark of neuroblastoma cells. We have previously presented data to suggest that in situ differentiation in tumors frequently proceeds ...

Single‐Cell Atlas Reveals Tumorigenic Profiles and Immune Dynamics of Adrenal Incidentalomas
Single‐cell RNA sequencing reveals cellular heterogeneity in adrenal incidentalomas, identifying distinct tumor cell populations. Clusterin is recognized as a biomarker for adrenocortical tumors, correlating with established markers. MYCN‐positive clusters in pheochromocytomas indicated poorer survival.

Functional characterization of the catalytic site of the tetanus toxin light chain using permeabilized adrenal chromaffin cells [PDF]
The molecular events underlying the inhibition of exocytosis by tetanus toxin were investigated in permeabilized adrenal chromaffin cells. We found that replacement of amino acid residues within the putative zinc binding domain of the tetanus toxin light

Spatiotemporal distribution of neural crest cells in the common wall lizard Podarcis muralis
Abstract Background Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers.

SOX2+ sustentacular cells are stem cells of the postnatal adrenal medulla
Renewal of the catecholamine-secreting chromaffin cell population of the adrenal medulla is necessary for physiological homeostasis throughout life. Definitive evidence for the presence or absence of an adrenomedullary stem cell has been enigmatic.

ABSTRACT Pheochromocytoma and paraganglioma (together PPGL) are tumours with a high degree of heritability. Genetic landscape is divided into three clusters, cluster 1 (Krebs/pseudohypoxia signalling pathway), cluster 2 (kinase signalling pathway) and cluster 3 (Wnt signalling pathway).
