Malignant glomus tumor of the gastric antrum with hepatic metastases: a case report and literature review

open access: yesHuman Pathology: Case Reports, 2018
Glomus tumor (glomangioma) is an uncommon pericytic neoplasm derived from glomus cells, which are modified smooth muscle cells of the glomus body. Malignant glomus tumors (glomangiosarcomas) are extremely rare mesenchymal neoplasms.

Hydrogen sulfide and hypoxia-induced changes in TASK (K2P3/9) activity and intracellular Ca2+ concentration in rat carotid body glomus cells

open access: yesRespiratory Physiology & Neurobiology, 2015
Acute hypoxia depolarizes carotid body chemoreceptor (glomus) cells and elevates intracellular Ca2+ concentration ([Ca2+]i). Recent studies suggest that hydrogen sulfide (H2S) may serve as an oxygen sensor/signal in the carotid body during acute hypoxia.

Molecular Mechanisms of Acute Oxygen Sensing by Arterial Chemoreceptor Cells. Role of Hif2α

open access: yesFrontiers in Physiology, 2020
Carotid body glomus cells are multimodal arterial chemoreceptors able to sense and integrate changes in several physical and chemical parameters in the blood. These cells are also essential for O2 homeostasis.

Glomus tumour in the forearm: a case report and review of mri findings

open access: yesJournal of the Belgian Society of Radiology, 2010
Glomus tumours are uncommon benign neoplasms characterised by the proliferation of modified smooth muscle cells known as glomus cells. Glomus tumours are well described in the extremities, particularly in the sub-ungual region and MRI is well established

Glucose sensing by carotid body glomus cells: potential implications in disease

open access: yesFrontiers in Physiology, 2014
The carotid body (CB) is a key chemoreceptor organ in which glomus cells sense changes in blood O2, CO2, and pH levels. CB glomus cells have also been found to detect hypoglycemia in both non-primate mammals and humans. O2 and low-glucose responses share

Successful Resection of locally infiltrative Glomus Tumor without pulmonary resection [PDF]

open access: yes, 2017
Introduction: Extracutaneous glomus tumors occurring in the bronchus is very rare. Complete resection is basic procedure for treatment of glomus tumor.

Effects of modulators of AMP-activated protein kinase on TASK-1/3 and intracellular Ca2+ concentration in rat carotid body glomus cells

open access: yesRespiratory Physiology & Neurobiology, 2014
Acute hypoxia depolarizes carotid body chemoreceptor (glomus) cells and elevates intracellular Ca2+ concentration ([Ca2+]i). Recent studies suggest that AMP-activated protein kinase (AMPK) mediates these effects of hypoxia by inhibiting the background K+

Neurotransmission in the carotid body: transmitters and modulators between glomus cells and petrosal ganglion nerve terminals. [PDF]

open access: yesBrain research. Brain research reviews, 2004
The carotid body (CB) is the main arterial chemoreceptor. The most accepted model of arterial chemoreception postulates that carotid body glomus (type 1) cells are the primary receptors, which are synaptically connected to the nerve terminals of petrosal

Slow Turning Lateral Vessel Bioreactor Improves Embryoid Body Formation and Cardiogenic Differentiation of Mouse Embryonic Stem Cells. [PDF]

open access: yes, 2013
Embryonic stem cells (ESCs) have the ability to form aggregates, which are called embryoid bodies (EBs). EBs mimic early embryonic development and are commonly produced for cardiomyogenesis.

Cxs and Panx- hemichannels in peripheral and central chemosensing in mammals

open access: yesFrontiers in Cellular Neuroscience, 2014
Connexins (Cxs) and Pannexins (Panx) form hemichannels at the plasma membrane of animals. Despite their low open probability under physiological conditions, these hemichannels release signaling molecules (i.e., ATP, Glutamate, PGE2) to the extracellular ...
