Effect of Neopterin on Splenic Erythropoiesis in Mice

Pteridines, 2010
Neopterin is produced by monocytes and is a biomarker for inflammation. We recently found that neopterin induces stromal cells to produce cytokines that suppress erythropoiesis in the bone marrow of mice.

Is There any Relationship Between the Repeated Complications of Sickle Cell Disease and the Potential Development of Acute Leukemia?

Oncology and Therapy
Sickle cell disease (SCD) is a severe monogenic hereditary hemoglobinopathy that is characterized by repeated clinical and biological manifestations able to generate stress erythopoiesis.

Vimentin downregulation is an inherent feature of murine erythropoiesis and occurs independently of lineage [PDF]

, 1990
In mammalian erythropoiesis, the mature cells of the primitive lineage remain nucleated while those of the definitive lineage are anuclear. One of the molecular and structural changes that precedes enucleation in cells of the definitive lineage is the ...

THE INFLUENCE OF THE ETHYLMETHYLHYDROXYPYRINE MALATE ON THE ABSOLUTE QUANTITY OF ERYTHROCYTE ISLETS IN THE CONDITION OF SULFUR DIOXIDES IMPACT ON THE DIFFERENT STAGES OF ONTOGENY

Архивъ внутренней медицины, 2017
Anthropogenic impact leads not only to contamination of environmental components, but also to the negative impact on the human body, especially blood is very sensitive to the effects of unfavorable environmental factors.

An intriguing case of a paravertebral extramedullary erythropoiesis presenting as tumor‐mimicking lesion in a patient with eosinophilia with FIP1L1‐PDGFRA rearrangement

Clinical Case Reports, 2022
Extramedullary hematopoiesis in the posterior mediastinum is rare. Our case interested a 28‐year‐old man with a history of eosinophilia with FIP1L1‐PDGFRA fusion gene who had a mediastinal mass surgically excised. Pathological examination concluded to an

Erythropoiesis Differences in Various Clinical Phases of Dengue Fever using Immature Reticulocyte Fraction Parameter

International Journal of Integrated Health Sciences, 2021
Objective: To determine the mechanism of erythropoiesis that led to anemia using the Immature Reticulocyte Fraction (IRF) parameter in various clinical phases of dengue fever.

Phylogeny and Ontogeny of Erythropoiesis [PDF]

BioMed Research International, 2015
Erythrocytes are essential for survival of vertebrates due to their ability to take up, bind, and transport oxygen. Recent study clarified that the number of cells in adult human is ~3.7 × 1013 cells and about 2/3 are erythrocytes (Bianconi et al. (2013) Ann Hum Biol. 40: 463).

FOXO1 regulates pentose phosphate pathway-mediated induction of developmental erythropoiesis

Frontiers in Cell and Developmental Biology, 2022
Primitive, neonatal and adult erythroid cells have been previously shown to have an active pentose phosphate pathway (PPP) that fuels various processes.

A critical role for mTORC1 in erythropoiesis and anemia

eLife, 2014
Red blood cells (RBC) must coordinate their rate of growth and proliferation with the availability of nutrients, such as iron, but the signaling mechanisms that link the nutritional state to RBC growth are incompletely understood.
