Streptozocin 120-123 erythropoietin Mus musculus 0-14 17928571-3 2008 The purpose of this study was to assess whether EPO protects the heart against cardiotoxicity induced by DOX. Doxorubicin 105-108 erythropoietin Mus musculus 48-51 17928571-4 2008 We found that DOX-induced apoptosis and impaired heart function in mice were largely prevented by EPO administration. Doxorubicin 14-17 erythropoietin Mus musculus 98-101 17928571-6 2008 EPO protected against DOX-induced cardiomyocyte death (by approximately 50%) and apoptosis assessed by annexin-V labeling, DNA fragmentation, and caspase-3 activity.

Adenosine 78-87 erythropoietin Mus musculus 163-177 17855480-1 2007 Previous studies have yielded conflicting results as to whether extracellular adenosine generation and signaling contributes to hypoxia-induced increases in renal erythropoietin (EPO) secretion. Adenosine 78-87 erythropoietin Mus musculus 179-182 17855480-2 2007 In this study, we combined pharmacological and genetic approaches to elucidate a potential contribution of extracellular adenosine to renal EPO release in mice. Adenosine 121-130 erythropoietin Mus musculus 140-143 17855480-8 2007 Together, these studies combine genetic and pharmacological in vivo evidence that increases of EPO secretion during limited oxygen availability are not affected by extracellular adenosine generation or signaling. Oxygen 124-130 erythropoietin Mus musculus 95-98 17724331-3 2007 Led by the intriguing observation that most of the mouse EPO-R (mEPO-R) is retained in the endoplasmic reticulum (ER), we hypothesized that sEPO-R is expressed at higher levels on the cell surface, thus maximizing the response to elevated EPO, which has been reported in this species. sepo-r 140-146 erythropoietin Mus musculus 57-60 17652365-1 2007 Apart from enhancing red blood cell production, erythropoietin (Epo) has been shown to modulate the ventilatory response to reduced oxygen supply.

Creatinine 24-26 erythropoietin Mus musculus 60-63 17584830-2 2007 Here we demonstrate that sEpoR, a negative regulator of Epo"s binding to the EpoR, is present in the mouse brain and is down-regulated by 62% after exposure to normobaric chronic hypoxia (10% O2 for 3 days). Oxygen 192-194 erythropoietin Mus musculus 26-29 17584830-4 2007 These observations imply that hypoxic downregulation of sEpoR is required for adequate ventilatory acclimatization to hypoxia, thereby underlying the function of Epo as a key factor regulating oxygen delivery not only by its classical activity on red blood cell production, but also by regulating ventilation.

Cisplatin 91-100 erythropoietin Mus musculus 50-64 12713714-1 2003 Current evidence suggests that a modulatory action on O(2)-dependent EPO secretion is exerted by the erythroid/precursor cell population in the erythropoietic organs through a negative feedback system. o(2) 54-58 erythropoietin Mus musculus 69-72 12713714-3 2003 Since erythropoietic depression was elicited by cyclophosphamide administration, which could have altered EPO production directly, the aim of the present investigation was to estimate hypoxia-stimulated EPO secretion in a mouse model of functional depressed erythropoiesis induced by exposure to normobaric hyperoxia. Cyclophosphamide 48-64 erythropoietin Mus musculus 106-109 12713714-12 2003 Data support the concept that the rate of erythropoiesis, perhaps through the number of the erythroid progenitor/precursor cell population, modulates O(2)-dependent EPO secretion. o(2) 150-154 erythropoietin Mus musculus 165-168 12727112-6 2003 Specifically, expression of Epo was dependent on the presence of a chimeric transcription factor that is activated by the orally available small molecule drug rapamycin.

Azacitidine 34-40 erythropoietin Mus musculus 88-91 12706120-4 2003 However, after being treated with 5-AzaC, 32D Ro cells acquired the ability to generate EPO-dependent clones (1 clone/10(4) cells) which gave rise to EPO-dependent cell lines. Azacitidine 34-40 erythropoietin Mus musculus 150-153 12706120-5 2003 All the 10 EPO-responsive cell lines independently isolated from 5-AzaC-treated 32D Ro cells had erythroid morphology and expressed high levels of alpha- and beta-globin. Azacitidine 65-71 erythropoietin Mus musculus 11-14 12706120-7 2003 Therefore, 5-AzaC treatment reactivates the potential of the myeloid-restricted 32D Ro cells to generate EPO-responsive erythroid clones suggesting that gene methylation played an important role in the G-CSF-mediated restriction/activation of the differentiation potential of these cells.

AZD 1480 13-20 erythropoietin Mus musculus 55-61 29697839-1 2018 Study Objectives: Based on the fact that erythropoietin (Epo) administration in rodents protects against spatial learning and cognitive deficits induced by chronic intermittent hypoxia (CIH)-mediated oxidative damage, here we tested the hypothesis that Epo in the brain protects against cardiorespiratory disorders and oxidative stress induced by CIH in adult mice. cih 186-189 erythropoietin Mus musculus 41-55 29787432-9 2018 In addition, BBT-059 inhibited the induction of radiation-induced hematopoietic biomarkers, thrombopoietin, erythropoietin, and Flt-3 ligand. bbt-059 13-20 erythropoietin Mus musculus 108-122 30315639-2 2018 Along with this canonical role, EPO is also reported to modulate energy metabolism, resulting in improved glucose tolerance and insulin sensitivity. Glucose 106-113 erythropoietin Mus musculus 32-35 30315639-3 2018 EPO also stimulates the production of the hormone erythroferrone (ERFE) which acts to suppress hepcidin production, thus increasing dietary iron absorption and mobilizing stored iron for use in erythropoiesis. erythroferrone 50-64 erythropoietin Mus musculus 0-3 30315639-3 2018 EPO also stimulates the production of the hormone erythroferrone (ERFE) which acts to suppress hepcidin production, thus increasing dietary iron absorption and mobilizing stored iron for use in erythropoiesis.

Iron 178-182 erythropoietin Mus musculus 0-3 30315639-5 2018 As increased levels of circulating NEFA blunt insulin sensitivity and impair glucose tolerance, ERFE-induced clearance of NEFA after EPO administration would have a beneficial effect on glucose metabolism. Glucose 186-193 erythropoietin Mus musculus 133-136 30315639-9 2018 These findings suggest that the known beneficial effects of EPO on glucose metabolism are not attributable to an accompanying increase in ERFE production, and that Erfe is dispensable for normal glucose homeostasis.

Aminoglycosides 126-140 erythropoietin Mus musculus 90-93 29654830-5 2018 Auditory brainstem response (ABR) thresholds were measured in 12-weeks-old mice before and after treatment with kanamycin for 15 days, which resulted in both C57BL/6 and EPO-transgenic animals in a high-frequency hearing loss. Kanamycin 112-121 erythropoietin Mus musculus 170-173 29654830-8 2018 In conclusion, neuronal overexpression of EPO is protective against aminoglycoside-induce hearing loss, which is in accordance with its known neuroprotective effects in other organs, such as the eye or the brain. Aminoglycosides 68-82 erythropoietin Mus musculus 42-45 29632923-5 2018 The results showed that the red blood cell count, the hemoglobin amount and the hematocrit of mice in the ginsenoside groups could be restored to normal values in a short time, and the effects of both Rk3 and Rh4 are obviously better than those of EPO.
