GTP and Ca2+ Modulate the Inositol 1,4,5-Trisphosphate-Dependent Ca2+ Release in Streptolysin O-Permeabilized Bovine Adrenal Chromaffin Cells [PDF]

, 1991
The inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release was studied using streptolysin O-permeabilized bovine adrenal chromaffin cells. The IP3-induced Ca2+ release was followed by Ca2+ reuptake into intracellular compartments.

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, Volume 9, Issue 1, January 2026.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...

Inhibition by Selenium Compounds of Catecholamine Secretion Due to Inhibition of Ca2+ Influx in Cultured Bovine Adrenal Chromaffin Cells

Journal of Pharmacological Sciences, 2006
.: Selenium is an essential trace metal element, whereas large doses of selenium exert adverse effects to the human body. We examined the effects of selenium compounds, sodium selenite (Na2SeO3) and sodium selenate (Na2SeO4), on catecholamine secretion ...

Chromogranin A in the olfactory system of the rat [PDF]

, 1990
The olfactory bulb of the rat contains chromogranin A at a similar level as the adrenal gland or the hypophysis as revealed by immunoblots. Olfactory chromogranin A also displays the same size as chromogranin A of endocrine cells.

Navigating Solute Carrier Transporters—A Comprehensive Review of Functionalized Small Molecule Probes for Target Identification and Characterization

Medicinal Research Reviews, Volume 46, Issue 1, Page 238-271, January 2026.
ABSTRACT Solute carrier transporters (SLCs) are integral membrane proteins that play pivotal roles in maintaining cellular homeostasis by mediating the transport of a diverse range of substrates across cell membranes. With their involvement in fundamental physiological processes such as nutrient uptake, neurotransmitter signaling, and drug transport ...

Alcohol and the endocrine system: A critical review of disruptions, potential mechanisms, and health implications

Alcohol, Clinical and Experimental Research, Volume 50, Issue 1, January 2026.
The endocrine system coordinates whole body cellular function and maintains homeostasis. Alcohol impacts the integrity of endocrine regulation at multiple sites, contributing to risk for comorbidities. Some of the alcohol‐mediated pathophysiological effects on the endocrine system include alterations in receptor expression and responsiveness, protein ...

SOX2+ sustentacular cells are stem cells of the postnatal adrenal medulla

Nature Communications
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.

Differentiation in neuroblastoma: diffusion-limited hypoxia induces neuro-endocrine secretory protein 55 and other markers of a chromaffin phenotype. [PDF]

PLoS ONE, 2010
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 ...

Plasma Membrane and Chromaffin Granule Characteristics in Digitonin‐Treated Chromaffin Cells [PDF]

Journal of Neurochemistry, 1985
Abstract: Digitonin permeabilizes the plasma membranes of bovine chromaffin cells to Ca2+, ATP, and proteins and allows micromolar Ca2+ in the medium to stimulate directly catecholamine secretion. In the present study the effects of digitonin (20 μM) on the plasma membrane and on intracellular chromaffin granules were further characterized. Cells with

Ca2+-Stimulated Catecholamine Release from alpha-Toxin Permeabilized PC12 Cells [PDF]

, 1987
Two possible cellular pathways of catecholamines from the chromaffin vesicles of PC 12 cells to the surrounding medium are explored in this study. The direct one circumventing the cytoplasm can be activated in a-toxin-permeabilized cells with micromolar ...
