This study describes the relationship among proliferation, survival, and apoptosis with the expression of key molecules related to tumoral hypoxia (hypoxia-inducible factor (HIF)-1α, erythropoietin (EPO), vascular endothelial growth factor (VEGF)), their receptors (EPO-R, VEGFR-2), and stearoyl desaturase-1 (SCD-1) in early stages of ccRCC.
The relationship of erythropoietin overexpression with von Hippel-Lindau tumour suppressor gene mutations between hypoxia-inducible factor-1α and -2α in sporadic clear cell renal carcinoma.
Elevated number of circulating EPCs seems to be related to high EPO production from RCC with novel double somatic mutation of the VHL gene in this patient.
We report the clinical to molecular analysis in a patient in whom a thrombotic myocardial infarction was the first manifestation of a clear cell renal carcinoma associated with an elevated serum EPO level (109 U/L) and erythrocytosis (hemoglobin 200 g/L [20 g/dL]).
The present study examines whether EPO could elicit such a proliferative and thereby potentially detrimental response in cells of human renal-cell carcinoma (RCC).
