Erythropoietin-producing lung cancer.
A 68-year-old Japanese man (never smoker) underwent total gastrectomy for stomach cancer in November 1998. In March 2005, he was treated for macrocytic anemia by injections of vitamin B12. In August 2006, he was found to have chronic myelomonocytic leukemia associated with iron deficiency anemia. Blood examination showed a red cell count 5.05×10/L, hemoglobin 11.4 g/dL, hematocrit 38.5%, white ...
متن کاملDeletion of von Hippel-Lindau protein converts renin-producing cells into erythropoietin-producing cells.
States of low perfusion pressure of the kidney associate with hyperplasia or expansion of renin-producing cells, but it is unknown whether hypoxia-triggered genes contribute to these changes. Here, we stabilized hypoxia-inducible transcription factors (HIFs) in mice by conditionally deleting their negative regulator, Vhl, using the Cre/loxP system with renin-1d promoter-driven Cre expression. V...
متن کاملRenal erythropoietin-producing cells in health and disease
Erythropoietin (Epo) is an indispensable erythropoietic hormone primarily produced from renal Epo-producing cells (REPs). Epo production in REPs is tightly regulated in a hypoxia-inducible manner to maintain tissue oxygen homeostasis. Insufficient Epo production by REPs causes renal anemia and anemia associated with chronic disorders. Recent studies have broadened our understanding of REPs from...
متن کاملQuantitation of erythropoietin-producing cells in kidneys of mice by in situ hybridization: correlation with hematocrit, renal erythropoietin mRNA, and serum erythropoietin concentration.
In situ hybridization was used to quantitate the cells that produce erythropoietin (EP) in the renal cortices of mice with varying severities of acute anemia and of mice recovering from severe, acute anemia. The number of EP-producing cells in the renal cortex increased in an exponential manner as hematocrit was decreased. Individual EP-producing cells had very similar densities of silver grain...
متن کاملRegulated oxygen sensing by protein hydroxylation in renal erythropoietin-producing cells.
The kidney is a major site of systemic oxygen sensing, regulating blood erythrocyte and hence oxygen content by hypoxia-inducible erythropoietin (Epo) expression. A constant ratio between blood perfusion and oxygen consumption, a stable corticomedullary oxygen gradient, and a relatively low tissue Po(2) are the prerequisites for the function of renal Epo-producing and oxygen-sensing (REPOS) cel...
