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
The aim of our study was to investigate the appearance, density and distribution of ghrelin cells and GHS-R1a and GHS-R1b in the human stomach and duodenum during prenatal and early postnatal development. We examined chromogranin-A and ghrelin cells in duodenum, and GHS-R1a and GHS-R1b expression in stomach and duodenum by immunohistochemistry in embryos, fetuses, and infants. Chromogranin-A and ghrelin cells were identified in the duodenum at weeks 10 and 11 of gestation. Ghrelin cells were detected individually or clustered within the base of duodenal crypts and villi during the first trimester, while they were presented separately within the basal and apical parts of crypts and villi during the second and third trimesters. Ghrelin cells were the most numerous during the first (∼11%) and third (∼10%) trimesters of gestation development. GHS-R1a and GHS-R1b were detected at 11 and 16 weeks of gestation, showed the highest level of expression in Brunner's gland and in lower parts of duodenal crypts and villi during the second trimester in antrum, and during the third trimester in corpus and duodenum. Our findings demonstrated for the first time abundant duodenal expression of ghrelin cells and ghrelin receptors during human prenatal development indicating a role of ghrelin in the regulation of growth and differentiation of human gastrointestinal tract.

Abstract
Psychological stress affects different physiological processes including haematopoiesis. However, erythropoietic effects of chronic psychological stress remain largely unknown. The adult spleen contains a distinct microenvironment favourable for rapid expansion of erythroid progenitors in response to stressful stimuli, and emerging evidence suggests that inappropriate activation of stress erythropoiesis may predispose to leukaemic transformation. We used a mouse model to study the influence of chronic psychological stress on erythropoiesis in the spleen and to investigate potential mediators of observed effects. Adult mice were subjected to 2 hrs daily restraint stress for 7 or 14 consecutive days. Our results showed that chronic exposure to restraint stress decreased the concentration of haemoglobin in the blood, elevated circulating levels of erythropoietin and corticosterone, and resulted in markedly increased number of erythroid progenitors and precursors in the spleen. Western blot analysis revealed significantly decreased expression of both erythropoietin receptor and glucocorticoid receptor in the spleen of restrained mice. Furthermore, chronic stress enhanced the expression of stem cell factor receptor in the red pulp. Moreover, chronically stressed animals exhibited significantly increased expression of bone morphogenetic protein 4 (BMP4) in the red pulp as well as substantially enhanced mRNA expression levels of its receptors in the spleen. These findings demonstrate for the first time that chronic psychological stress activates BMP4-dependent extramedullary erythropoiesis and leads to the prolonged activation of stress erythropoiesis pathways. Prolonged activation of these pathways along with an excessive production of immature erythroid cells may predispose chronically stressed subjects to a higher risk of leukaemic transformation.

Abstract
The aim of our study was to investigate HER-2 and TOP2A gene status and their correlation with Bcl-2, p53, Ki67, ssDNA, and clinicopathological parameters in four molecular subtypes of breast cancer. Seventy-four paraffin-embedded samples are immunohistochemically studied for the expression of estrogen receptor (ER), progesterone receptor (PR), HER-2, p53, Bcl-2, ssDNA, and Ki67, while HER-2 and TOP2A gene status by fluorescence in situ hybridization was investigated in 60 samples. Luminal A and B subtypes were characterized with small tumor size, intermediate histological grade, negative lymph node, and metastatic status, while triple negative and HER-2 positive subtypes were associated with larger tumor size, poorly differentiated tumors, and positive lymph node status. p53, Ki67, and ssDNA expression was higher in triple negative and HER-2 positive than in luminal subtypes, while ER, PR, and Bcl-2 dominated in luminal subtypes. HER-2 gene status was higher in luminal B and HER-2 positive than in luminal A and triple negative subtypes, while TOP2A gene status was similar. HER-2 gene status positively correlated with TOP2A gene status, HER-2 receptor, and histological grade, while negative correlation characterized relationship between HER-2 gene status and ER, PR, and Bcl-2. The shortened overall survival period characterized patients from triple negative breast cancer subtype (18.7 months). HER-2 and TOP2A gene amplification showed a tendency to be associated with larger tumor size, positive lymph node status, high level of apoptotic and proliferative indexes, and low level of p53 and Bcl-2 expression, which all together indicate group of patients with similar outcome during the progression of the disease.

Abstract
BACKGROUND Since reports on endocrine cells and their kinetics in the corpus of the human stomach are limited, the aim of this study was to examine the appearance, localization, density, and the relationship among the endocrine cell types in the corpus of the human stomach during prenatal and early postnatal development. METHODS We examined chromogranin A, somatostatin, ghrelin, glucagon, and serotonin expression by immunohistochemistry in 2 embryos, 38 fetuses, and 3 infants in the corpus of human stomach. RESULTS Chromogranin A secreting endocrine cells were identified in the corpus at week 10 of gestation. Somatostatin cells were present from the 10th week, ghrelin and serotonin cells from the 11th week, and glucagon cells from the 12th week of gestation. Endocrine cells were present individually or clustered within the glandular base and body during the first trimester, and were present separately within the basal and central parts of glands during the second and third trimesters. Somatostatin cells were the most common type of cells (~46 %) during the first trimester, while ghrelin cells were the most numerous during the second trimester (~34 %), and in infants (~28 %). The percentage of glucagon cells was significant only during the first trimester of pregnancy (5.5 %), and the percentage of serotonin cells was only significant just before birth (4.8 %). CONCLUSIONS These results show, for the first time, that the largest number of endocrine cells are present in the corpus during the first trimester of prenatal development. Also, these results suggest that secretory products of endocrine cells play a role in the regulation of homeostasis, growth, and differentiation, and in human stomach function.

Abstract
The pancreas appears to be a major source of ghrelin during fetal development, but the ontogeny of ghrelin cells in the human pancreas and their developmental relationship with α- and β-cells remain largely unknown. In the present study, we examined the dynamics of ghrelin cell growth, colocalization of ghrelin with major pancreatic hormones and defined the similarities and differences among developmental patterns of ghrelin-, glucagon- and insulin-expressing cells in the human pancreas. To this end, paraffin-embedded pancreatic tissue sections from human embryos and fetuses were assessed by immunohistochemistry. Ghrelin-positive cells were first detected in the pancreas of 11-week-old fetuses. With advancing gestational age, both ghrelin- and glucagon-expressing cells were increasingly observed at the periphery of the developing islets, whereas insulin-containing cells were typically found in the islet core. Double immunohistochemistry showed that ghrelin-expressing cells were clearly separate from insulin-, somatostatin- and pancreatic polypeptide-containing cells. In contrast, cells coexpressing ghrelin and glucagon were sporadically detected during both the early and late fetal periods. Furthermore, morphometric analysis revealed a similar trend in the volume density of ghrelin- and glucagon-positive cells, and a contrasting pattern in β-cell density at specific time points during the development of the human pancreas. This study demonstrates that the developmental pattern of ghrelin cells, although clearly distinct, is quite similar to that of glucagon-expressing cells. The obtained findings indicate a close lineage relationship between these cell populations, a functional relationship between their secretory products and an auto/paracrine mode of ghrelin-glucagon interaction in pancreatic development.
