Arai S, Yasukawa M, Shibata S. Role of selenium in the pathophysiology of cardiorenal anaemia syndrome. ESC Heart Fail 2024. [PMID: 39223820 DOI: 10.1002/ehf2.14893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 05/02/2024] [Accepted: 05/20/2024] [Indexed: 09/04/2024] Open
Abstract
Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)]. Several lines of evidence indicate that CRAS confers a worse prognosis, suggesting the need to clarify the underlying pathophysiology. Among the micronutrients (trace elements) that are essential to humans, inadequate iron status has previously been implicated in the pathogenesis of CRAS; however, the roles of other trace elements remain unclear. Selenium critically regulates the function of selenoproteins, in which selenocysteine is present at the active centres. The human genome encodes 25 selenoproteins, and accumulating data indicate that they regulate diverse physiological processes, including cellular redox homeostasis, calcium flux, thyroid hormone activity and haematopoiesis, all of which directly or indirectly influence cardiac function. The essential role of selenium in human health is underscored by the fact that its deficiency results in multiple disorders, among which are cardiomyopathy and abnormal erythrocyte morphology. Studies have shown that selenium deficiency is not uncommon in CKD patients with poor nutritional status, suggesting that it may be an under-recognized cause of anaemia and cardiovascular disorders in these patients. In this review, we discuss the role of selenium in the pathophysiology of CKD, particularly in the context of the interconnection among CKD, cardiac dysfunction and anaemia. Given that selenium deficiency is associated with treatment-resistant anaemia and an increased risk of CVD, its role as a key modulator of CRAS merits future investigation.

Association between low selenoprotein P concentrations and anaemia in hospitalized heart failure patients. ESC Heart Fail 2024; 11:877-882. [PMID: 38200550 DOI: 10.1002/ehf2.14651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 11/22/2023] [Accepted: 12/12/2023] [Indexed: 01/12/2024] Open
Abstract
AIMS Heart failure (HF) patients with anaemia tend to have a worse outcome, with increased hospitalization rates, decreased exercise tolerance, and higher mortality compared to those without anaemia. Limited research exists on the association between selenium deficiency and anaemia specifically in HF patients, despite previous findings of a correlation in different populations. The BIOSTAT-CHF study demonstrated that higher selenium levels in HF patients were associated to a lower risk of anaemia and iron deficiency. This study investigates the relationship between selenoprotein P (SELENOP) concentrations, a major contributor and functional biomarker of selenium transport, and anaemia, Hb levels, and iron status in hospitalized HF patients. METHODS AND RESULTS SELENOP was analysed in 320 hospitalized HF subjects, with complete data available for 310 subjects. The relationships between continuous SELENOP concentrations and 1) Hb concentrations, 2) anaemia (Hb < 115 g/L (women), <130 g/L (men)), and 3) iron status (as measured by transferrin receptor 1 (TfR1) which increases in iron deficiency) were evaluated using multivariable logistic and linear regression models. Additionally, SELENOP concentrations in the lowest quartile were related to anaemia, haemoglobin, and iron state in multivariable logistic and linear models. The mean age of the study population was 75.0 ± 11.6 years, and 30% were women. Anaemia was present in 133 subjects (42.9%). SELENOP concentrations were positively correlated with haemoglobin concentrations (0.238; P < 0.001) and negatively with TfR1 concentrations (-0.238, P < 0.001). In multivariable regression models, higher SELENOP concentrations were associated with higher Hb concentrations (B = 3.23; P = 0.002) and lower TfR1 concentrations (B = -0.20; P < 0.001). Furthermore, SELENOP deficiency was associated with lower Hb concentrations (B = -7.64: P = 0.001), higher TfR1 concentrations (B = 0.31; P = 0.003), and higher odds of anaemia in HF patients (odds ratio 2.17; 95% confidence interval 1.23-3.82; P = 0.008). CONCLUSIONS In hospitalized heart failure patients, lower concentrations of SELENOP were associated with higher prevalence of anaemia.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 340:122846.

Abstract
Amphibians are more susceptible to environmental stressors than other vertebrates due to their semipermeable skin and physiological adaptations to living in very specific microhabitats. Therefore, the aim of the present study was to investigate the effects of a metal mixture from settleable particulate matter (SePM) released from metallurgical industries on Lithobates catesbeianus tadpoles. Endpoints analyzed included metal bioconcentration, morphological (biometrical indices), hematological parameters (hemoglobin and blood cell count), and erythrocyte DNA damage (genotoxicity and mutagenicity). American bullfrog tadpoles (Gosner's stage 25) were kept under control condition (no contaminant addition) or exposed to a sub-lethal and environmentally relevant concentration (1 g.L-1) of SePM for 96 h. Tadpoles exposed to SePM exhibited elevated whole blood levels of Fe56, AL, Sn, Pb, Zn, Cr, Cu, Ti, Rb, V, Ce, La, Ag, As. SePM-exposed tadpoles showed a significant decrease in condition factor (12%) and increases in hepatosomatic index (25%), hemoglobin concentration (17%), and total leukocytes (82%), thrombocytes (90%), and monocytes (78%) abundance. In addition, exposed tadpoles showed higher MN and ENAs (340 and 140%, respectively) frequencies, and erythrocyte DNA damage with approximately 1.2- to 1.8-fold increases in comet parameters. Taken together, these results suggest that the multimetal mixture found in SePM is potentially genotoxic and mutagenic to L. catesbeianus tadpoles, induces stress associated with hematological changes, and negatively affects growth. Although such contamination occurs at sublethal levels, regulatory standards are needed to control the emission of SePM and protect amphibian populations.

Abstract
Background The oxidant/ antioxidant balance is disrupted in anemia. Antioxidant capacity depends on antioxidant enzyme activity and some trace elements. This study aimed to evaluate oxidant/ antioxidant status and its correlation with red blood cell indices and anemia severity in anemic patients. Methods Blood samples were taken from 90 anemic patients and 95 healthy people. Circulatory miR-122 was assayed by real-time PCR. Malondialdehyde (MDA), pro-oxidant/ antioxidant balance (PAB), supper oxide demitasse (SOD), glutathione peroxidase (GPxs) activity, total antioxidant capacity (TAC), and zinc were measured by colorimetric method. Selenium was also determined using atomic absorption. Results Selenium and zinc decreased significantly in the case group (**P=0.004 and ***P=0.000). The amount of miR-122 up-regulated in the anemia (**P=0.003). MDA was significantly raised in the case vs control (***P=0.0002). PAB was higher in the case group (**P=0.005). SOD and GPxs activity was decreased along with TAC in anemic patients (*P=0.02, **P=0.008, *P=0.038). Zinc and PAB levels correlated with some red blood cell indices. PAB was associated with anemia severity. Conclusions Increased PAB and decreased zinc/selenium increased oxidant levels in anemic patients. RBC indices and anemia severity were correlated with oxidant/ antioxidant somewhere.

Abstract
Myocardial ischemic/reperfusion (IR) injury is a global cardiovascular disease with high mortality and morbidity. Therapeutic interventions for myocardial ischemia involve restoring the occluded coronary artery. However, reactive oxygen species (ROS) inevitably impair the cardiomyocytes during the ischemic and reperfusion phases. Antioxidant therapy holds great promise against myocardial IR injury. The current therapeutic methodologies for ROS scavenging depend predominantly on administering antioxidants. Nevertheless, the intrinsic drawbacks of antioxidants limit their further clinical transformation. The use of nanoplatforms with versatile characteristics greatly benefits drug delivery in myocardial ischemic therapy. Nanoplatform-mediated drug delivery significantly improves drug bioavailability, increases therapeutic index, and reduces systemic toxicity. Nanoplatforms can be specifically and reasonably designed to enhance molecule accumulation at the myocardial site. The present review initially summarizes the mechanism of ROS generation during the process of myocardial ischemia. The understanding of this phenomenon will facilitate the advancement of innovative therapeutic strategies against myocardial IR injury. The latest developments in nanomedicine for treating myocardial ischemic injury are then discussed. Finally, the current challenges and perspectives in antioxidant therapy for myocardial IR injury are addressed.

Abstract
BACKGROUND Most data on anemia in children with intestinal failure (IF) have been obtained from studies in which the data were collected at a single point in time. We aimed to identify the frequency of anemia and factors associated with hemoglobin levels in children with IF during their course of home parenteral nutrition. METHODS We performed a longitudinal cohort study of patients with IF followed up at a pediatric intestinal rehabilitation center. Outcome variables were hemoglobin levels and prevalence of anemia during the follow-up period. The exposure variables were age, duration of parenteral nutrition, chronic disease, and serum concentrations of C-reactive protein, iron, copper, selenium, vitamins A, D, B12 , and folic acid. RESULTS Twenty-five children with a median time of receiving parenteral nutrition of 40.7 months were included. A median (and interquartile range) of 40.7 (25.2-58) hemoglobin measurements were performed per patient. Mean (SD) hemoglobin was 10.7 (1.8) g/dL at baseline and 11.6 (0.9) g/dL in the last observation (paired t test, P = 0.07); 32% of patients had mean hemoglobin values below the lower limit for age. In a multivariable predictive model, having C-reactive protein >1 mg/dL was associated with a decrease of 0.57 g/dL in hemoglobin (95% CI, -0.90 to -0.24, P = 0.01), and an increase of 1 mg/L in vitamin A concentration was associated with the increase of 0.93 g/dL in Hb level (95% CI, 0.24-1.61; P = 0.008). CONCLUSION Anemia affects almost one-third of children with IF and its frequency decreases during the follow-up period. Hemoglobin levels are associated with inflammatory response and serum micronutrient concentrations.

Abstract
Neurological diseases remain a major concern due to the high world mortality rate and the absence of appropriate therapies to cross the blood-brain barrier (BBB). Therefore, the major focus is on the development of such strategies that not only enhance the efficacy of drugs but also increase their permeability in the BBB. Currently, nano-scale materials seem to be an appropriate approach to treating neurological diseases based on their drug-loading capacity, reduced toxicity, targeted delivery, and enhanced therapeutic effect. Selenium (Se) is an essential micronutrient and has been of remarkable interest owing to its essential role in the physiological activity of the nervous system, i.e., signal transmission, memory, coordination, and locomotor activity. A deficiency of Se leads to various neurological diseases such as Parkinson's disease, epilepsy, and Alzheimer's disease. Therefore, owing to the neuroprotective role of Se (selenium) nanoparticles (SeNPs) are of particular interest to treat neurological diseases. To date, many studies investigate the role of altered microbiota with neurological diseases; thus, the current review focused not only on the recent advancement in the field of nanotechnology, considering SeNPs to cure neurological diseases, but also on investigating the potential role of SeNPs in altered microbiota.

Abstract
To study the effects of the seleno-chitosan on daily gain, wool yield, and blood parameters in the Chinese merino sheep in the selenium (Se)-deficient pastures. The samples of soils, forages, and tissues had been collected in the Southern Xinjiang of Northwest China. Our findings indicated that the Se contents in soils and forages from affected pastures were remarkably lower than those unaffected by the pastures (P < 0.01). The Se contents in the blood and the wool from affected Chinese merino sheep were extremely lower than those from healthy sheep. Meanwhile, the values of Hb, PCV, and PLT in affected sheep were significantly decreased (P < 0.01). The yield of wool and the growth rate in affected sheep were also remarkably reduced (P < 0.01). The affected Chinese merino sheep were orally treated by seleno-chitosan for 150 days; the Se contents in blood were remarkably increased and reached the healthy range on day 5. The blood parameters soon recovered to a healthy range on day 10. The growth rate of sheep in the treated group was remarkably higher than that in the control animals. The yield of the wool was also significantly increased in the treated group. Consequently, the Se-deprived environment caused a threat to daily gain, wool yield, and blood parameters in the Chinese merino sheep. The seleno-chitosan could not only markedly increase the Se contents blood contents, but also significantly increase the production performance (daily gain and wool yield), and release the symptoms of anemia in the Se-deprived animal.

Abstract
We have found that the Reclamation merino sheep in Southern Xinjiang, China, showed emaciation, stiff limbs, instability, and sudden death, which is related to the impairment of immune function and antioxidant capacity caused by selenium (Se) deficiency. The experiments were to study the effects of Se-enriched malt on the immune and antioxidant function in Se-deprived Reclamation merino sheep in Southern Xinjiang, China. The samples of soil and forage had been collected from tested pastures, and animal tissues were also collected in tested animals. The mineral content of soil, forage, and animal tissues was measured in the collected samples. Hematological indexes and biochemical values were also examined. The findings showed that the Se contents were extremely lower in affected soil and forage than those from healthy soil and forage (P < 0.01). The Se contents in affected blood and wool were also extremely lower than those from healthy blood and wool (P < 0.01). The values in glutathione peroxidase and total antioxidant capacity in affected serum samples were also extremely lower than those from healthy serum samples, and levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide were extremely higher in affected serum samples than those from healthy serum samples (P < 0.01). Meanwhile, the values of hemoglobin, packed cell volume, and platelet count from affected blood were extremely lower than those from healthy blood (P < 0.01). The levels of interleukin (IL)-1β, IL-2, tumor necrosis factor-alpha, immunoglobulin A, and immunoglobulin G in serum were extremely decreased in the affected Reclamation merino sheep (P < 0.01). The levels of IL-6 and immunoglobulin M in serum were extremely reduced in the affected Reclamation merino sheep compared to healthy animals (P < 0.01). The animals in affected pastures were orally treated with Se-enriched malt, and the Se contents in blood were extremely increased (P < 0.01). The immune function and antioxidant indicator returned to within the healthy range. Consequently, our findings were indicated that the disorder of the Reclamation merino sheep was mainly caused by the Se deficiency in soil and forage. The Se-enriched malt could not only markedly increase the Se content in blood but also much improve the immune function and the antioxidant capacity in the Se-deprived Reclamation merino sheep.

Abstract
The experiments were to study the effects of Se-yeast on immune and antioxidant in Selenium(Se)-deprived Pishan red sheep in Southern Xinjiang, China. The samples of soil, forage, and animal tissues were collected, and used for measuring mineral content, physiological parameter, and biochemical values. These findings showed that the Se contents in affected soil and forage were markedly lower than those from unaffected soil and forage (P < 0.01). Se in affected blood and wool were also extremely lower than those from healthy Pishan red sheep (P < 0.01). The hemoglobin, packed cell volume, platelet count, Glutathione peroxidase, and total antioxidant capacity in the affected Pishan red sheep were markedly lower than those from healthy ones too (P < 0.01). The levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide in Pishan red sheep from affected pastures were extremely higher than those from healthy ones (P < 0.01). The levels of interleukin (IL)-1β, Interleukin-2, tumor necrosis factor-α and interleukin-6 from serum were markedly decreased in affected Pishan red sheep(P < 0.01). The Pishan red sheep in Se-deprived pasture were treated by orally with Se-yeast, the amount of Se in the blood markedly increased in treated animals. Meanwhile, the immune and antioxidant indicator was returned to the healthy values. Consequently, our findings were indicated that Se-deprived forage caused oxidative damage, and a serious threat to the immune function in animals. The Se-yeast is more effective in the Se-deficient Pishan red sheep including blood Se content, immune function and the antioxidant capacity.

Abstract
Psoriasis and neurodegenerative diseases (NDs) are important medical, social and economic issues. The possible relationship of psoriasis and NDs has not been established yet. This study involved 60 patients with plaque-type psoriasis. Serum concentrations of fatty acid-binding protein 7 (FABP-7), glutamic acid (GA) and neurofilament light chain (NFL), which have been hardly studied in psoriasis before, were measured by ELISA before and after 12 weeks of treatment with acitretin or methotrexate. The concentration of FABP-7 and NFL in patients before the treatment was significantly higher than in the controls (p < 0.01, p < 0.001, respectively). After the treatment their concentration decreased, although FABP-7 did so insignificantly. The concentration of GA did not differ significantly between patients and controls and before and after the treatment but we found its negative correlation with CRP (p < 0.05). The duration of psoriasis does not seem to directly affect the risk of neurodegeneration and the severity only in patients with worse skin condition. Elevated FABP-7 and NFL, which are present in the brain, may be considered as potential indicators of NDs development in psoriatics, although it surely requires further research. GA might correspond with neuroinflammation in psoriasis. Systemic antipsoriatic therapy could be studied in order to improve cognitive impairment through lowering NDs biomarkers in some cases.

Abstract
Selenium, a trace element fundamental to human health, is incorporated as the amino acid selenocysteine (Sec) into more than 25 proteins, referred to as selenoproteins. Human mutations in SECISBP2, SEPSECS and TRU-TCA1-1, three genes essential in the selenocysteine incorporation pathway, affect the expression of most if not all selenoproteins. Systemic selenoprotein deficiency results in a complex, multifactorial disorder, reflecting loss of selenoprotein function in specific tissues and/or long-term impaired selenoenzyme-mediated defence against oxidative and endoplasmic reticulum stress. SEPSECS mutations are associated with a predominantly neurological phenotype with progressive cerebello-cerebral atrophy. Selenoprotein deficiency due to SECISBP2 and TRU-TCA1-1 defects are characterized by abnormal circulating thyroid hormones due to lack of Sec-containing deiodinases, low serum selenium levels (low SELENOP, GPX3), with additional features (myopathy due to low SELENON; photosensitivity, hearing loss, increased adipose mass and function due to reduced antioxidant and endoplasmic reticulum stress defence) in SECISBP2 cases. Antioxidant therapy ameliorates oxidative damage in cells and tissues of patients, but its longer term benefits remain undefined. Ongoing surveillance of patients enables ascertainment of additional phenotypes which may provide further insights into the role of selenoproteins in human biological processes.

Missense mutation in selenocysteine synthase causes cardio-respiratory failure and perinatal death in mice which can be compensated by selenium-independent GPX4. Redox Biol 2021; 48:102188.

Abstract
Selenoproteins are a small family of proteins containing the trace element selenium in form of the rare amino acid selenocysteine (Sec), which is decoded by the UGA codon. In humans, a number of pathogenic variants in genes encoding distinct selenoproteins or selenoprotein biosynthesis factors have been identified. Pathogenic variants in selenocysteine synthase (SEPSECS), which catalyzes the last step in Sec-tRNA[Ser]Sec biosynthesis, were reported in children suffering from progressive cerebello-cerebral atrophy. To understand the pathomechanism associated with SEPSECS deficiency, we generated a novel mouse model recapitulating the respective human pathogenic p.Y334C variant in the murine Sepsecs gene (SepsecsY334C). Unlike in patients, pups homozygous for the p.Y334C variant died perinatally with signs of cardio-respiratory failure. Perinatal death is reminiscent of the Sedaghatian spondylometaphyseal dysplasia disorder in humans, which is caused by pathogenic variants in the gene encoding the selenoprotein and key ferroptosis regulator glutathione peroxidase 4 (GPX4). Protein expression levels of distinct selenoproteins in SepsecsY334C/Y334C mice were found to be generally reduced in brain and isolated cortical neurons, while transcriptomics analysis uncovered an upregulation of NRF2-regulated genes. Crossbreeding of SepsecsY334C/Y334C mice with mice harboring a targeted mutation of the catalytically active Sec to Cys in GPX4 rescued perinatal death of SepsecsY334C/Y334C mice, showing that the cardio-respiratory defects of SepsecsY334C/Y334C mice were caused by the lack of GPX4. Like in SepsecsY334C/Y334C mice, selenoprotein expression levels remained low and NRF2-regulated genes remained highly expressed in these compound mutant mice, indicating that selenium-independent GPX4, along with a sustained antioxidant response are sufficient to compensate for dysfunctional Sec-tRNA[Ser]Sec biosynthesis. Our findings imply that children with pathogenic variants in SEPSECS or GPX4 may even benefit from treatments that incompletely compensate for impaired GPX4 activity.

Abstract
Simple Summary Psoriasis and lichen planus are common skin diseases which have similar clinical presentation and pathogenesis. Considering these dermatoses are frequent and decrease patients’ life quality, it is important to look for different markers indicating patients’ condition which can possibly affect the choice of the treatment. MAdCAM-1 and ITGB7 molecules and their serum levels in patients with psoriasis and lichen planus have never been studied before; therefore, we are the first trying to analyze it in order to develop the current state of knowledge on psoriasis and lichen planus to better help patients. Abstract Plaque psoriasis (PSO) and lichen planus (LP) are skin diseases with some similarities in pathogenesis, comorbidities, and clinical presentation. Mucosal addressin cell adhesion molecule-1 (MAdCAM-1) and its ligand, α4β7 integrin, are involved in inflammatory bowel diseases and liver dysfunctions, which occur more frequently in PSO and LP. Serum MAdCAM-1 and ITGB7 levels in patients with plaque PSO and eruptive LP have never been studied before. The study included 42 patients with PSO, 13 with LP, and 23 controls. Serum molecules levels were evaluated using the immune–enzymatic method. ITGB7 concentration was not statistically different, both in patients with PSO and LP, compared to controls (both p > 0.05). MAdCAM-1 level was significantly lower in PSO subjects than in controls (p = 0.041), whereas in the LP group, a downward trend was observed (p = 0.088) with p = 0.0455 in ANOVA. Multiple linear regression revealed independent associations between ITGB7 and HDL and BMI and RBC in the LP group. In psoriatic patients with elevated CRP, there was an upward trend for MAdCAM-1, and also a positive correlation between MAdCAM-1 and WBC. ITGB7 and MAdCAM-1 cannot serve as markers of disease activity or liver pathology neither in patients with PSO nor LP. MAdCAM-1 might play a role as an inflammation indicator in PSO and a beneficial influence on the lipid profile in LP.

Abstract
Ferroptosis is a form of regulated cell necrosis, as a consequence of Fe(II)-dependent lipid peroxidation. Although ferroptosis has been linked to cancer cell death, neurodegeneration and reperfusion injury, physiological roles of ferroptosis have not been elucidated to date mostly due to the lack of appropriate methodologies. Here, we show that 4-hydroxy-2-nonenal (HNE)-modified proteins detected by a HNEJ-1 mouse monoclonal antibody is a robust immunohistochemical technology to locate ferroptosis in tissues in combination with morphological nuclear information, based on various models of ferroptosis, including erastin-induced cysteine-deprivation, conditional Gpx4 knockout and Fe(II)-dependent renal tubular injury, as well as other types of regulated cell death. Specificity of HNEJ-1 with ferroptosis was endorsed by non-selective identification of HNE-modified proteins in an Fe(II)-dependent renal tubular injury model. We further comprehensively searched for signs of ferroptosis in different developmental stages of Fischer-344 rats from E9.5-2.5 years of age. We observed that there was a significant age-dependent increase in ferroptosis in the kidney, spleen, liver, ovary, uterus, cerebellum and bone marrow, which was accompanied by iron accumulation. Not only phagocytic cells but also parenchymal cells were affected. Epidermal ferroptosis in ageing SAMP8 mice was significantly promoted by high-fat or carbohydrate-restricted diets. During embryogenesis of Fischer-344 rats, we found ferroptosis in nucleated erythrocytes at E13.5, which disappeared in enucleated erythrocytes at E18.5. Administration of a ferroptosis inhibitor, liproxstatin-1, significantly delayed erythrocyte enucleation. Therefore, our results demonstrate for the first time the involvement of ferroptosis in physiological processes, such as embryonic erythropoiesis and aging, suggesting the evolutionally acquired mechanism and the inevitable side effects, respectively.

Abstract
Selenium (Se) is an essential element to human health that can be obtained in nature through several sources. In the human body, it is incorporated into selenocysteine, an amino acid used to synthesize several selenoproteins, which have an active center usually dependent on the presence of Se. Although Se shows several beneficial properties in human health, it has also a narrow therapeutic window, and therefore the excessive intake of inorganic and organic Se-based compounds often leads to toxicity. Nanoparticles based on Se (SeNPs) are less toxic than inorganic and organic Se. They are both biocompatible and capable of effectively delivering combinations of payloads to specific cells following their functionalization with active targeting ligands. Herein, the main origin of Se intake, its role on the human body, and its primary biomedical applications are revised. Particular focus will be given to the main therapeutic targets that are explored for SeNPs in cancer therapies, discussing the different functionalization methodologies used to improve SeNPs stability, while enabling the extensive delivery of drug-loaded SeNP to tumor sites, thus avoiding off-target effects.

Abstract
Few studies have examined the association of serum selenium with anemia-related indicators and risk of anemia. We conducted a cross-sectional analysis of 2,902 adults in 2003-2004 National Health and Nutrition Examination Survey database. Multivariable linear and logistic regression models were used to examine the association of serum selenium with anemia-related indicators and risk of anemia. The nonlinear relationship was analyzed using a generalized additive model with the smoothing plot. A total of 1,472 males and 1,430 females with a mean age of 61.94 ± 13.73 years were included. Compared with the lowest quintile, the highest quintile of serum selenium was associated with increased level of serum iron (β = 12.44, 95% confidence interval [CI]: 7.14, 17.75, p < .001), mean corpuscular hemoglobin concentration (MCHC) (β = 0.14, 95%CI: 0.02, 0.26, p = .020), and hemoglobin (β = 0.40, 95%CI: 0.19, 0.61, p < .001), and decreased risk of anemia (odds ratio [OR] = 0.47, 95%CI: 0.28, 0.77, p = .002). Furthermore, smoothed plots suggested the nonlinear relationships between serum selenium and MCHC, hemoglobin level, and risk of anemia. Interestingly, on the left of inflection point, serum selenium was associated with decreased risk of anemia (OR = 0.972, 95%CI: 0.960, 0.985, p < .001), and then, the risk of anemia increased with increasing serum selenium concentration (OR = 1.011, 95%CI: 1.002, 1.021, p = .023). Future large-scale, polycentric prospective studies should be conducted to verify our results.

Abstract
Selenium (Se) is an essential trace element that maintains normal physiological functions in organisms. Since the discovery of glutathione peroxidase (GSH-PX), public interest in selenoproteins has gradually increased. Based on previous studies, dietary Se maintains erythrocyte homeostasis through selenoprotein-induced mediation of redox reactions. Furthermore, both the surface phosphatidylserine (PS) and intramembrane stomatin contents can be used as indicators of erythrocyte osmotic fragility. This study focused on the mechanism by which dietary Se deficiency increases erythrocyte osmotic fragility. We fed Se-deficient grain to mice for 8 weeks to establish a Se deficiency model in mice. We measured Se levels in the blood as well as the activities of antioxidant enzymes associated with selenoproteins in a Se-deficient environment. We used Western blotting, routine blood analysis, and other methods to detect red blood cell oxidative stress levels, membrane stomatin levels, and PS externalization. Fresh blood was collected to test erythrocyte osmotic fragility. The results showed that antioxidant enzyme activity was affected by dietary Se deficiency. Oxidative stress increased lipid peroxidation and the ROS content in the blood of the mice. Under such conditions, decreased PS exposure and stomatin content in the erythrocyte membrane eventually affected the structure of the erythrocyte membrane and increased erythrocyte osmotic fragility.

Abstract
Przewalski's gazelle (Procapra przewalskii) is an endangered ungulate in the Qinghai-Tibet Plateau of China. This study aimed to determine the influence of selenium (Se) deprivation in the natural habitat on the immune index and antioxidant capacity of P. przewalskii. Samples of soil and forage were collected from affected and healthy areas, and animal tissues were collected from affected and healthy P. przewalskii. The samples were used for measuring mineral content and for hematological and biochemical analyses. The results showed that Se concentrations were significantly lower in the soil and mixed forage samples from the affected area than in those from the healthy area. The Se concentrations were significantly lower in blood and hair samples from affected P. przewalskii than in those from healthy P. przewalskii. Meanwhile, hemoglobin, packed cell volume, and platelet count of affected P. przewalskii were significantly lower than those of healthy P. przewalskii. The serum level of glutathione peroxidase and total antioxidant capacity were significantly lower and the serum levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide were significantly higher in affected P. przewalskii. The serum levels of interleukin (IL)-1β, IL-2, tumor necrosis factor-alpha, immunoglobulin A (IgA), and IgG significantly decreased and the serum levels of IL-6 and IgM significantly reduced in affected P. przewalskii compared with healthy P. przewalskii. Therefore, the findings indicated that Se deprivation in soil and forage caused oxidative stress damage and posed a serious threat to the immune function of P. przewalskii.

Abstract
PURPOSE OF REVIEW Erythropoiesis is a complex multistep process going from committed erythroid progenitors to mature red cells. Although recent advances allow the characterization of some components of erythropoiesis, much still remains to be investigated particularly on stress erythropoiesis. This review summarizes recent progresses made to understand the impact of oxidative stress on normal and pathologic erythropoiesis. RECENT FINDINGS During erythroid maturation, reactive oxygen species might function as second messenger through either transient oxidation of cysteine residues on signaling targets or modulation of intracellular signaling pathways. Thus, in erythropoiesis, efficient cytoprotective systems are required to limit possible reactive oxygen species-related toxic effects especially in stress erythropoiesis characterized by severe oxidation such as β-thalassemia. In addition, prolonged or severe oxidative stress impairs autophagy, which might contribute to the block of erythroid maturation in stress erythropoiesis. Understanding the functional role of cytoprotective systems such as peroxiredoxin-2 or classical molecular chaperones such as the heat shock proteins will contribute to develop innovative therapeutic strategies for ineffective erythropoiesis. SUMMARY We provide an update on cytoprotective mechanisms against oxidation in normal and stress erythropoiesis. We discuss the role of oxidative sensors involved in modulation of intracellular signaling during erythroid maturation process in normal and stress erythropoiesis.

Abstract
Selenoprotein P (SeP), a member of hepatokines, is involved in the development of various metabolic diseases closely related to psoriasis, but it has not been explored in that dermatosis so far. The study aimed to evaluate the clinical value of serum SeP concentrations in patients with psoriasis and its interplay between disease activity, metabolic or inflammatory parameters and systemic therapy. The study included thirty-three patients with flared plaque-type psoriasis and fifteen healthy volunteers. Blood samples were collected before and after three months of treatment with methotrexate or acitretin. Serum SeP levels were evaluated using the immune–enzymatic method. SeP concentration was significantly higher in patients with psoriasis than in the controls (p < 0.05). Further, in patients with severe psoriasis, SeP was significantly increased, compared with the healthy volunteers before treatment, and significantly decreased after (p < 0.05, p = 0.041, respectively). SeP positively correlated with C-reactive protein and platelets and negatively with red blood counts (p = 0.008, p = 0.013, p = 0.022, respectively). Therapy resulted in a significant decrease in SeP level. Selenoprotein P may be a novel indicator of inflammation and the metabolic complications development in psoriatics, especially with severe form or with concomitant obesity. Classic systemic therapy has a beneficial effect on reducing the risk of comorbidities by inhibiting SeP.

Abstract
Aplastic anemia (AA) is characterized as hypoplasia of bone marrow hematopoietic cells and hematopenia of peripheral blood cells. Though the supplement of exogenous erythropoietin (EPO) has been clinically approved for AA treatment, the side-effects hinder its further application. Here a robust treatment for AA induced by chemotherapy drugs is explored using gadofullerene nanoparticles (GFNPs). Methods: The gadofullerene were modified with hydrogen peroxide under alkaline conditions to become the water-soluble nanoparticles (GFNPs). The physicochemical properties, in vitro chemical construction, stability, hydroxyl radical scavenging ability, in vitro cytotoxicity, antioxidant activity, in vivo treatment efficacy, therapeutic mechanism and biological distribution, metabolism, toxicity of GFNPs were examined. Results: GFNPs with great stability and high-efficiency antioxidant activity could observably increase the number of red blood cells (RBC) in the peripheral blood of AA mice and relieve the abnormal pathological state of bone marrow. The erythropoiesis mainly includes hemopoietic stem cells (HSCs) differentiation, erythrocyte development in bone marrow and erythrocyte maturation in peripheral blood. The positive control-EPO promotes erythropoiesis by regulating HSCs differentiation and erythrocyte development in bone marrow. Different from the anti-AA mechanism of EPO, GFNPs have little impact on both the differentiation of HSCs and the myeloid erythrocyte development, but notably improve the erythrocyte maturation. Besides, GFNPs can notably decrease the excessive reactive oxygen species (ROS) and inhibit apoptosis of hemocytes in blood. In addition, GFNPs are mostly excreted from the living body and cause no serious toxicity. Conclusion: Our work provides an insight into the advanced nanoparticles to powerfully treat AA through ameliorating the erythrocyte maturation during erythropoiesis.

Calf thymus polypeptide improved hematopoiesis via regulating colony-stimulating factors in BALB/c mice with hematopoietic dysfunction. Int J Biol Macromol 2020; 156:204-216.

Abstract
Calf thymus polypeptide (CTP) is prepared from calf thymus. It has a molecular mass of <10 kilodalton (kDa) and contains 17 types of amino acids. This study investigated the hematopoietic function-improvement effect of CTP in CHRF, K562, and bone marrow mononuclear cells; mice with immunosuppression; and with hematopoietic dysfunction. In mice with immunosuppression, CTP enhanced the cytotoxic activity of natural killer cells and the proliferation of lymphocytes and regulated the levels of immunoglobulins. It also enhanced the proliferation and differentiation of CHRF and K562 cells by upregulating the expression of proliferation- and differentiation-related proteins. In mice with hematopoietic dysfunction, CTP restored white blood cell, neutrophil, and hemoglobin proportions in the peripheral blood and enhanced the levels of B lymphocytes and hematopoietic stem cells and progenitor cells in the bone marrow. CTP effectively regulated the levels of hematopoiesis-related cytokines, such as granulocyte colony-stimulating factor (G-CSF), macrophage colony-stimulating factor (M-CSF), interleukin 2, and interferons-γ, and enhanced the expression of hematopoiesis-related proteins in both primary bone marrow cells and mice with hematopoietic dysfunction. These results indicate that CTP has hematopoietic function-improvement effect and this effect may be related to the modulation of colony-stimulating factors (CSFs) and related signaling pathways.

Beneficial antioxidant status of piglets from sows fed selenomethionine compared with piglets from sows fed sodium selenite. J Trace Elem Med Biol 2020; 58:126439.

Abstract
BACKGROUND Studies in mammals proved dietary organic selenium (Se) being superior to inorganic Se regarding effects on growth performance, antioxidative status, immune response, and Se homeostasis. However, the picture of possible effects of different Se sources and - levels can be expanded. The present field study evaluated the effects on weight gain, hematological and selected biochemical variables as well as plasma concentrations of vitamin E (vitE), total Se and selenobiomolecules in piglets throughout the suckling period. METHODS Piglets were monitored from birth to 38 days of age (d). The mother sows' diets were enriched with l-selenomethionine (SeMet-0.26 and -0.43 mg Se/kg feed) or sodium selenite (NaSe-0.40 and -0.60 mg Se/kg feed) from 1 month prior to farrowing until the end of lactation period. Piglets received pelleted feed supplemented with Se similarly to the sows' diets from one week of age. Selenite at 0.40 mg Se/kg (NaSe-0.40) represents a common Se source and -level in pig feed and served as control diet. RESULTS From 24d, piglets in SeMet-groups had higher mean body weight (BW) compared with piglets from sows fed NaSe-0.40. Furthermore, from five-d and above, piglets from sows fed NaSe-0.60 had significantly higher BW than offspring from sows fed NaSe-0.40. Neonatal piglets in group SeMet-0.43 had significantly lower red blood cell counts (RBC), hemoglobin (Hgb) and hematocrit (Hct) concentrations compared with piglets from sows fed with NaSe-0.40. Neonatal and 5d-old piglets in group SeMet-0.26 showed higher gamma-glutamyl transferase activity than piglets in group NaSe-0.40. From five d and above, group NaSe-0.60 excelled with increased specific hematological variables culminating at age 38d with increased Hct, mean corpuscular volume (MCV), and MC hemoglobin (MCH) as well as increased activities of aspartate transaminase and lactate dehydrogenase compared with the other groups. Generally, offspring in the SeMet groups had higher total Se-concentrations in plasma than those from sows fed selenite, and showed a dose-response effect on plasma Se-concentrations. Furthermore, SeMet-fed piglets had higher plasma levels of the selenoproteins (Sel) glutathione peroxidase 3 (GPx3) and SelP as well as selenoalbumin. Plasma vitE levels were significantly negatively correlated with RBC throughout trial period. CONCLUSIONS Maternal supplementation with SeMet during gestation influenced hematology and clinical biochemistry in neonatal piglets in a different way than in offspring from sows receiving selenite enriched diets. Growth performance was positively influenced by both dietary Se source and Se level. Higher plasma levels of GPx3 observed in piglets receiving SeMet probably improved the protection against birth or growth related oxidative stress. These might prime the piglets for demanding situations as indicated by higher weight gain in offspring from sows fed with SeMet-supplemented diets. Our results on some enzyme activities might indicate that piglets fed NaSe-0.60 had to cope with increased levels of oxidative stress compared with those originating from sows fed SeMet or lower dietary levels of selenite. We assume that combining inorganic and organic Se sources in complete feed for breeding sows might be beneficial fro reproduction and the offspring's performance.

Abstract
BACKGROUND Mediterranean diets limit red meat consumption and increase intakes of high-phytate foods, a combination that could reduce iron status. Conversely, higher intakes of fish, a good source of selenium, could increase selenium status. OBJECTIVES A 1-y randomized controlled trial [New Dietary Strategies Addressing the Specific Needs of the Elderly Population for Healthy Aging in Europe (NU-AGE)] was carried out in older Europeans to investigate the effects of consuming a Mediterranean-style diet on indices of inflammation and changes in nutritional status. METHODS Selenium and iron intakes and status biomarkers were measured at baseline and after 1 y in 1294 people aged 65-79 y from 5 European countries (France, Italy, the Netherlands, Poland, and the United Kingdom) who had been randomly allocated either to a Mediterranean-style diet or to remain on their habitual, Western diet. RESULTS Estimated selenium intakes increased significantly with the intervention group (P < 0.01), but were not accompanied by changes in serum selenium concentrations. Iron intakes also increased (P < 0.001), but there was no change in iron status. However, when stratified by study center, there were positive effects of the intervention on iron status for serum ferritin for participants in Italy (P = 0.04) and France (P = 0.04) and on soluble transferrin receptor (sTfR) for participants in Poland (P < 0.01). Meat intake decreased and fish intake increased to a greater degree in the intervention group, relative to the controls (P < 0.01 for both), but the overall effects of the intervention on meat and fish intakes were mainly driven by data from Poland and France. Changes in serum selenium in the intervention group were associated with greater changes in serum ferritin (P = 0.01) and body iron (P = 0.01), but not sTfR (P = 0.73); there were no study center × selenium status interactions for the iron biomarkers. CONCLUSIONS Consuming a Mediterranean-style diet for 1 y had no overall effect on iron or selenium status, although there were positive effects on biomarkers of iron status in some countries. The NU-AGE trial was registered at clinicaltrials.gov as NCT01754012.

Abstract
Selenium (Se) is an essential trace element that functions in the form of the 21st amino acid, selenocysteine (Sec) in a defined set of proteins. Se deficiency is associated with pathological conditions in humans and animals, where incorporation of Sec into selenoproteins is reduced along with their expression and catalytic activity. Supplementation of Se-deficient population with Se has shown health benefits suggesting the importance of Se in physiology. An interesting paradigm to explain, in part, the health benefits of Se stems from the observations that selenoprotein-dependent modulation of inflammation and efficient resolution of inflammation relies on mechanisms involving a group of bioactive lipid mediators, prostanoids, which orchestrate a concerted action toward maintenance and restoration of homeostatic immune responses. Such an effect involves the interaction of various immune cells with these lipid mediators where cellular redox gatekeeper functions of selenoproteins further aid in not only dampening inflammation, but also initiating an effective and active resolution process. Here we have summarized the current literature on the multifaceted roles of Se/selenoproteins in the regulation of these bioactive lipid mediators and their immunomodulatory effects.

Abstract
Red blood cells, or erythrocytes, make up approximately a quarter of all cells in the human body with over 2 billion new erythrocytes made each day in a healthy adult human. This massive cellular production system is coupled with a set of cell biological processes unique to mammals, in particular, the elimination of all organelles, and the expulsion and destruction of the condensed erythroid nucleus. Erythrocytes from birds, reptiles, amphibians and fish possess nuclei, mitochondria and other organelles: erythrocytes from mammals lack all of these intracellular components. This review will focus on the dynamic changes that take place in developing erythroid cells that are interacting with specialized macrophages in multicellular clusters termed erythroblastic islands. Proerythroblasts enter the erythroblastic niche as large cells with active nuclei, mitochondria producing heme and energy, and attach to the central macrophage via a range of adhesion molecules. Proerythroblasts then mature into erythroblasts and, following enucleation, in reticulocytes. When reticulocytes exit the erythroblastic island, they are smaller cells, without nuclei and with few mitochondria, possess some polyribosomes and have a profoundly different surface molecule phenotype. Here, we will review, step-by-step, the biophysical mechanisms that regulate the remarkable process of erythropoiesis with a particular focus on the events taking place in the erythroblastic island niche. This is presented from the biological perspective to offer insight into the elements of red blood cell development in the erythroblastic island niche which could be further explored with biophysical modelling systems.

Abstract
Sickle cell disease (SCD) is a genetic hemoglobinopathy characterized by chronic hemolysis. Chronic hemolysis is promoted by increased oxidative stress. Our hypothesis was that some antioxidant micronutrients (retinol, tocopherol, selenium, and zinc) would be determinant factors of the degree of hemolysis in SCD patients. We aimed to investigate the nutritional adequacy of these antioxidants and their relationships to hemolysis. The study included 51 adult SCD patients regularly assisted in two reference centers for hematology in the State of Rio de Janeiro, Brazil. Serum concentrations of retinol, alpha-tocopherol, selenium, and zinc were determined by high-performance liquid chromatography or atomic absorption spectrometry. Hematological parameters (complete blood count, reticulocyte count, hemoglobin, direct and indirect bilirubin, total bilirubin, lactate dehydrogenase) and inflammation markers (leukocytes and ultra-sensitive C-reactive protein) were analyzed. A linear regression model was used to test the associations between the variables. Most patients presented selenium deficiency and low selenium consumption. Linear regression analysis showed that selenium is the main determinant of hemolysis among the antioxidant nutrients analyzed. Thus, data from this study suggest that the nutritional care protocols for patients with SCD should include dietary sources of selenium in order to reduce the risk of hemolysis.
