Abstract
Cancer-related anemia (CRA) is a common multifactorial disorder that adversely affects the quality of life and overall prognosis in patients with cancer. Safety concerns associated with the most common CRA treatment options, including intravenous iron therapy and erythropoietic-stimulating agents, have often resulted in no or suboptimal anemia management for many cancer patients. Chronic anemia creates a vital need to restore normal erythropoietic output and therefore activates the mechanisms of stress erythropoiesis (SE). A growing body of evidence demonstrates that bone morphogenetic protein 4 (BMP4) signaling, along with glucocorticoids, erythropoietin, stem cell factor, growth differentiation factor 15 (GDF15) and hypoxia-inducible factors, plays a pivotal role in SE. Nevertheless, a chronic state of SE may lead to ineffective erythropoiesis, characterized by the expansion of erythroid progenitor pool, that largely fails to differentiate and give rise to mature red blood cells, further aggravating CRA. In this review, we summarize the current state of knowledge on the emerging roles for stress erythroid progenitors and activated SE pathways in tumor progression, highlighting the urgent need to suppress ineffective erythropoiesis in cancer patients and develop an optimal treatment strategy as well as a personalized approach to CRA management.

Abstract
NEW FUNDINGS What is the central question of this study? This study aims to assess whether an anemic state could modify adiposity and metabolic parameters in hypothalamic obese rats. What is the main finding and its importance? Our results indicate that hypothalamic obese rats do not display iron deficiency. However, the pharmacological induction of anemia in hypothalamic-obese rats resulted in reduced adiposity, characterized by a decrease in subcutaneous white and brown adipose tissue depots. These findings suggest that iron imbalance in obesity may elevate lipolysis. ABSTRACT Iron imbalance is frequent in obesity. Herein, we evaluated the impact of anemia induced by phenylhydrazine on adiposity and metabolic state of hypothalamic obese rats. Hypothalamic obesity was induced by high doses of glutamate monosodium (MSG; 4g/Kg) administered to neonatal male rats (n = 20). Controls (CTL; non-obese rats) received saline equimolar (n = 20). Rats were weaned at 21 days of life. At 70 days, half of the rats received three intraperitoneal doses of phenylhydrazine (PHZ; 40mg/Kg/dose) or saline solution. Body weight and food intake were accompanied for four weeks after PHZ administration. At 92 days, rats were euthanized, blood was collected for microcapillary hematocrit (Hct) analysis and plasma quantification of glucose, triglycerides, total cholesterol, and iron levels. The liver, the spleen, and the white (WAT) and brown (BAT) adipose tissues were excised, weighed, and used for histology. MSG-treated rats developed obesity, hypertriglyceridemia, and insulin resistance, compared to CTL rats, without changes in iron levels and Hct. PHZ administration reduced iron plasma levels and promoted similar tissue injuries in the spleen and liver from MSG and CTL rats. However, in MSG-treated rats, PHZ decreased fasting glucose levels and Hct, as well as diminished the subcutaneous WAT and BAT mass. Although MSG-obesity does not affect iron plasma levels and Hct by itself, PHZ-induced anemia associated with obesity induces a marked drop in subcutaneous WAT and BAT mass, suggesting that iron imbalance may lead to increased lipolytic responses in obese rats, compared to lean rats.

Abstract
Abstract
Background
This study was aimed at evaluating the hematinic effect of Spondias mombin and its protective role against the spleenotoxic effect of Phenylhydrazine (PHZ).
Methods
Thirty Wistar rats were randomized into 6 groups. Group A (Control) animals were neither given the extract nor PHZ. Rats in groups B and C were administered 150 mg/kg body weight and 300 mg/kg body weight doses of the extract respectively. Anemia was induced in rats in groups D and E by oral administration of 40 mg/kg body weight of PHZ and concomitantly administered 150 mg/kg body weight and 300 mg/kg body weight doses of the extract respectively. Anemia was also induced in rats in group F by administration of 40 mg/kg body weight of PHZ but without administration of the extract.
Results
Histology of the spleen show moderate expansion of the red pulp and contraction of lymphoid follicles in group F and mild follicular activation and sinus histiocytosis in group D. There were significant (p < 0.05) increase in the weight of the spleen in group F and decrease in group C. Results also show significant (p < 0.05) decreases in the RBC count in group F and increases in the Mean Corpuscular Volume and Mean Corpuscular Haemoglobin in groups D and E. There was also a significant (P < 0.05) decrease in the Mean Corpuscular Haemoglobin Count in group D.
Conclusion
This study shows the hematinic effect of Spondias mombin and its possible use in ethno-medicine in managing anemic conditions, as well as its potential in protecting against the spleenotoxic effect of PHZ.

Abstract
Mice lacking Cdk6 kinase activity suffer from mild anemia accompanied by elevated numbers of Ter119+ cells in the bone marrow. The animals show hardly any alterations in erythroid development, indicating that Cdk6 is not required for proliferation and maturation of erythroid cells. There is also no difference in stress erythropoiesis following hemolysis in vivo. However, Cdk6−/− erythrocytes have a shortened lifespan and are more sensitive to mechanical stress in vitro, suggesting differences in cytoskeletal architecture. Erythroblasts contain both Cdk4 and Cdk6, while mature erythrocytes apparently lack Cdk4 and their Cdk6 is partly associated with the cytoskeleton. We used mass spectrometry to show that Cdk6 interacts with a number of proteins involved in cytoskeleton organization. Cdk6−/− erythroblasts show impaired F-actin formation and lower levels of gelsolin, which interacts with Cdk6. We also found that Cdk6 regulates the transcription of a panel of genes involved in actin (de-)polymerization. Cdk6-deficient cells are sensitive to drugs that interfere with the cytoskeleton, suggesting that our findings are relevant to the treatment of patients with anemia – and may be relevant to cancer patients treated with the new generation of CDK6 inhibitors.

Abstract
This study was conducted to characterize better the response of rats to blood loss and hemolysis and to incorporate automated methods into the routine evaluations of those responses. Serial phlebotomies of 1.5-2.0 ml of blood per day for 5 days, or intraperitoneal injection of 50 mg kg(-1) phenylhydrazine (PHZ) for 3 days, were used to cause anemia associated with blood loss or hemolysis, respectively. Maximum decreases in red blood counts were observed on Day 3 in PHZ-treated animals (68%) and Day 4 in blood-loss animals (35%). In the routine complete blood count (CBC), hemoglobin, hematocrit/hemoglobin ratio and erythrocyte indices could be used to discriminate between the two treatments. Free plasma hemoglobin in PHZ-treated animals resulted in marked elevations of mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) with a 2:1 hematocrit/hemoglobin ratio rather than the anticipated 3:1 ratio. Although both groups of animals had elevated white blood cell counts, PHZ-treated animals also had monocytosis and basophilia. Reticulocyte counts were more sensitive than erythropoietin (EPO) concentrations in predicting erythroid changes. Maximum mean reticulocyte values were ca. 24% in serially phlebotomized animals and >99% in PHZ-treated rats. Plasma EPO levels were 4-10-fold higher than EPO levels in urine, kidney or liver. Flow cytometric differentials of rat bone marrow using 2, 7-dichlorofluorescin successfully predicted erythroid hyperplasia in both experimental groups. Erythrocyte indices returned to normal within 14 days and the remaining CBC parameters were normal within 28 days for both treatment groups. Reticulocyte counts remained slightly elevated on Day 28, but were normal when assessed at Day 56 in blood-loss and PHZ-treated animals.
