Abstract
Lanthanum (La)-based nanotherapeutics are therapeutically advantageous due to cytoplasmic oxygen species (ROS) levels for mediating intrinsic and extrinsic tumor cell apoptosis. While they have not been extensively explored for their potential to suppress malignancies in vivo. Correspondingly, we have formulated a unique lanthanum nanocarrier with high specific surface area, dendritic-divergent mesopores, importantly, exposing more active lanthanum sites. After surface PEGlytion and ICG loading in mesoporous channels, this fantastic nanoplatform can efficaciously enrich in malignant glioblastoma regions. Meaningfully, it can be sensitively dissociated for La ions release under weak acid (pH = 6.5) tumor microenvironment. Upon 808 nm light irradiation, high light-heat conversion efficiency is further proved, then this satisfied thermal in the tumor site progressively enhances ROS production by La ions. Owing to the synergistic oxidative therapy and photothermal therapy of our dendritic La nanoplatform, glioblastoma is efficaciously and synergistically prevented both in vitro and in vivo. All outcomes highlight the therapeutic potency of La based nanoplatform with radial mesopores to treat malignant cancer in vivo and encourage future translational exploration.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 923:171374.

Abstract
Heavy metals pose a potential health risk to humans when they enter the organism. Renal excretion is one of the elimination pathways and, therefore, investigations with kidney cells are of particular interest. In the present study, the effects of Ba(II), Eu(III), and U(VI) on rat and human renal cells were investigated in vitro. A combination of microscopic, biochemical, analytical, and spectroscopic methods was used to assess cell viability, cell death mechanisms, and intracellular metal uptake of exposed cells as well as metal speciation in cell culture medium and inside cells. For Eu(III) and U(VI), cytotoxicity and intracellular uptake are positively correlated and depend on concentration and exposure time. An enhanced apoptosis occurs upon Eu(III) exposure whereas U(VI) exposure leads to enhanced apoptosis and (secondary) necrosis. In contrast to that, Ba(II) exhibits no cytotoxic effect at all and its intracellular uptake is time-independently very low. In general, both cell lines give similar results with rat cells being more sensitive than human cells. The dominant binding motifs of Eu(III) in cell culture medium as well as cell suspensions are (organo-) phosphate groups. Additionally, a protein complex is formed in medium at low Eu(III) concentration. In contrast, U(VI) forms a carbonate complex in cell culture medium as well as each one phosphate and carbonate complex in cell suspensions. Using chemical microscopy, Eu(III) was localized in granular, vesicular compartments near the nucleus and the intracellular Eu(III) species equals the one in cell suspensions. Overall, this study contributes to a better understanding of the interactions of Ba(II), Eu(III), and U(VI) on a cellular and molecular level. Since Ba(II) and Eu(III) serve as inactive analogs of the radioactive Ra(II) and Am(III)/Cm(III), the results of this study are also of importance for the health risk assessment of these radionuclides.

Abstract
Rare earth nanomaterials (RE NMs), which are based on rare earth elements, have emerged as remarkable biomaterials for use in bone regeneration. The effects of RE NMs on osteogenesis, such as promoting the osteogenic differentiation of mesenchymal stem cells, have been investigated. However, the contributions of the properties of RE NMs to bone regeneration and their interactions with various cell types during osteogenesis have not been reviewed. Here, we review the crucial roles of the physicochemical and biological properties of RE NMs and focus on their osteogenic mechanisms. RE NMs directly promote the proliferation, adhesion, migration, and osteogenic differentiation of mesenchymal stem cells. They also increase collagen secretion and mineralization to accelerate osteogenesis. Furthermore, RE NMs inhibit osteoclast formation and regulate the immune environment by modulating macrophages and promote angiogenesis by inducing hypoxia in endothelial cells. These effects create a microenvironment that is conducive to bone formation. This review will help researchers overcome current limitations to take full advantage of the osteogenic benefits of RE NMs and will suggest a potential approach for further osteogenesis research.

Association between prenatal exposure to rare earth elements and the neurodevelopment of children at 24-months of age: A prospective cohort study. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 343:123201. [PMID: 38135135 DOI: 10.1016/j.envpol.2023.123201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 12/24/2023]
Abstract
The increasing consumption of rare earth elements (REEs) has resulted in a considerable risk of environmental exposure. However, the adverse effects of prenatal REEs exposure on children's neurodevelopment are not yet fully recognized. Therefore, we investigated the individual and joint effects of prenatal exposure to 13 REEs on children's neurocognitive development based on 809 mother-child pairs from a large birth cohort in Wuhan, China. Maternal urinary concentrations of 13 REEs were repeatedly measured by inductively coupled plasma mass spectrometry. Children's neurodevelopment [e.g., mental and psychomotor development index (MDI/PDI)] at 24-months was assessed using Bayley Scales of Infant Development of Chinese Revision. GEE and BKMR models were applied to estimate the individual and joint effects of prenatal REE exposure on child neurodevelopment level. After controlling for typical confounders, we observed that exposure to 9 REEs during the first trimester were significantly associated with decreased MDI scores [βs and 95% confidence intervals (CIs) ranging from -2.24 (-3.86 ∼ -0.63) to -1.44 (-2.26∼ -0.26)], and 7 REEs during third trimester were significantly associated decreased PDI scores [β and 95% CIs ranging from -1.95 (-3.19 ∼ -0.71) to -1.25 (-2.34 ∼ -0.16)]. Higher quantiles of REE mixture in first and third trimester were associated with decreased MDI and PDI score. Thulium, erbium in the first trimester and cerium, lanthanum in the third trimester accounted most importance to joint effects on MDI and PDI, respectively. In conclusion, prenatal exposure to higher concentrations of REEs during the first and third trimester were negative associated with children's neurodevelopment.

Abstract
Lanthanides have been frequently used as biomimetic compounds for NMR and fluorescence studies of Ca2+ binding proteins due to having similar physical properties and coordination geometry to Ca2+ ions. Here we report that a member of the neuronal calcium sensor family, neuronal calcium sensor 1, complexes with two lanthanide ions Tb3+ and Eu3+. The affinity for Tb3+ is nearly 50 times higher than that for Ca2+ (Kd,Tb3+ = 0.002 ± 0.0001 μM and Kd, Ca2+ = 91 nM) whereas Eu3+ binding is notably weaker, Kd,Eu3+ = 26 ± 1 μM. Interestingly, despite having identical charge and similar ionic radii, Tb3+ and Eu3+ ions exhibit a distinct binding stoichiometry for NCS1 with one Eu3+ and two Tb3+ ions bound per NCS1 monomer, as demonstrated in fluorescence titration and mass spectrometry studies. These results suggest that the lanthanides' affinity for the individual EF hands is fine-tuned by a small variation in the ion charge density as well as EF hand binding loop amino acid sequence. As observed previously for other lanthanide:protein complexes, the emission intensity of Ln3+ is enhanced upon complexation with the protein, likely due to the displacement of water molecules by oxygen atoms from the coordinating amino acid residues. The overall shape of the Tb3+NCS1 and Eu3+NCS1 monomer shows high levels of similarity compared to the Ca2+ bound protein based on their collision cross section. However, the distinct occupation of EF hands impacts NCS1 oligomerization and affinity for the D2R peptide that mimics the NCS1 binding site on the D2R receptor. Specifically, the Tb3+NCS1 complex populates the dimer and has comparable affinity for the D2R peptide, whereas Eu3+ bound NCS1 remains in the monomeric form with a negligible affinity for the D2R peptide.

Abstract
Despite the growing interest, the information available on rare earth elements (REEs) in the last two decades is relatively premature and sparse. The importance of these elements as indicators of soil and physiological processes and responses have contributed to the increased interest in these previously less considered elements in the environmental sciences. This study provides an overview of the content and distribution of rare earth elements in the soil in the vicinity of the hydrothermal volcanogenic As-Sb-Tl deposit of Allchar, North Macedonia. Elemental contents were determined by inductively coupled plasma mass spectrometry (ICP-MS). The light rare earth elements (LREEs) content in the study area ranges from 8.92 to 188 mg/kg, while the heavy rare earth elements (HREEs) content ranges from 1.95 to 42.7 mg/kg. It can be concluded that there is some enrichment of light REEs in the volcanic intrusive rocks of the Allchar mine area, including latite, quartz-latite, trachyte and occasionally andesite and dacite. The spatial distribution of HREEs is closely related to the lithology of the region, especially the sandstone and claystone, followed by layered and massive carbonate rocks (limestone, dolomite, marble) that occurred in the Middle and Upper Triassic.

Abstract
ZnO quantum dots (QDs) have received much attention as biomarkers and drug delivery systems in cancer treatment, due to their low cost, ease of preparation, and pH-responsive degradation. However, its applications are limited by the low quantum yield and light absorption. In this work, a lanthanum-doped zinc oxide (La-ZnO) QDs-based drug delivery platform was constructed. The results show that 4% La doping is the most beneficial for improving the fluorescent properties of the ZnO QDs. After loading the drug, the cell activity was 15% at ZnO@DOX and 12% at La-ZnO@DOX. According to in vitro and in vivo experiment results, the La-ZnO QDs show enhancement of the antitumor effect. Dual enhancement of fluorescence and anti-tumor effects make La-ZnO QDs promising as a drug delivery system in cancer treatment.

Abstract
The increasing exploitation and application of rare earth elements (REEs) may induce hazardous risks to freshwater aquatic organisms. Due to the lack of water quality criteria (WQC) and sufficient reliable toxicity data, little information is available on the ecological risk of REEs in surface water. In this study, lanthanum (La) toxicity data were collected from published toxicological studies, and the data quality was assessed using a toxicological data reliability assessment tool. To obtain more toxicity data, Daphnia magna, Cyprinus carpio, and Dania rerio embryos were selected as surrogate species, and an interspecies correlation estimation (ICE) model was used to predict the toxicity of La for untested species. The species sensitivity distributions (SSDs) of La toxicity and WQC were investigated. Differences were observed in the hazardous concentrations for 5% of species (HC5), but no statistically significant differences were noted in the SSD curves between the measured acute toxicity data and the predicted data. For the SSDs constructed from the measured toxicity data, the ICE-predicted toxicity data and all acute data supplemented with the ICE-predicted data, the acute WQC values of La were 88, 1022 and 256 μg/L, respectively. According to the SSD and corresponding HC5 of chronic toxicity data, the chronic WQC was 14 μg/L. The results provide a scientific reference for establishing WQC for freshwater aquatic organisms and ecological risk assessments of REEs.

Abstract
Nano lanthanum oxide particles (La2O3 NPs) are important nanoparticle materials which are widely used in photoelectric production, but their potential health hazards to the respiratory system are not clear. The purpose of this study was to explore the possible mechanism of lung injury induced by La2O3 NPs. In this study, 40 SPF male SD rats were randomly divided into low-, medium-, and high-dose groups and control groups, with 10 animals in each group. Rats were poisoned by tracheal injection. The low-, medium-, and high-dose groups were given La2O3 NPs suspension of 25, 50, and 100 mg/kg, respectively, and the control group was given an equal volume of high-temperature sterilized ultrapure water. The rats in each group were exposed once a week for 12 consecutive times. The gene transcription and protein expression levels of PINK1 and parkin in rat lung tissue were mainly detected. Compared with the control group, the gene transcription and protein expression levels of PINK1 and Parkin in the exposed group were significantly higher (p < 0.05). La2O3 NPs may activate PINK1/parkin-induced mitochondrial autophagy.

Kajjumba GW, Attene-Ramos M, Marti EJ. Toxicity of lanthanide coagulants assessed using four in vitro bioassays. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 800:149556. [PMID: 34399349 DOI: 10.1016/j.scitotenv.2021.149556] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 08/03/2021] [Accepted: 08/05/2021] [Indexed: 06/13/2023]
Abstract
Rare earth element (REE) coagulants are prime contenders in wastewater treatment plants to remove phosphorus; unlike typical coagulants, they are not affected by pH. However, the use of REEs in wastewater treatment could mean increased human exposure to lanthanides (Ln) through wastewater effluent discharge to the environment or through water reuse. Information on the toxicity of lanthanides is scarce and, where available, there are conflicting views. Using in vitro bioassays, we assessed lanthanide toxicity by evaluating four relevant endpoints: the change in mitochondrial membrane potential (Δψm), intracellular adenosine triphosphate (I-ATP), genotoxicity, and cell viability. At less than 5000 μmol-Ln3+/L, lanthanides increased the Δψm, while above 5000 μmol-Ln3+/L, the Δψm level plummeted. The measure of I-ATP indicated constant levels of ATP up to 250 μmol-Ln3+/L, above which the I-ATP decreased steadily; the concentration of La, Ce, Gd, and Lu that triggered half of the cells to become ATP-inactive is 794, 1505, 1488, 1115 μmol-Ln3+/L, respectively. Although La and Lu accelerated cell death in shorter studies (24 h), chronic studies using three cell growth cycles showed cell recovery. Lanthanides exhibited antagonistic toxicity at less than 1000 μmol-Ln3+/L. However, the introduction of heavy REEs in a solution amplified lanthanide toxicity. Tested lanthanides appear to pose little risk, which could pave the way for lanthanide application in wastewater treatment.

Lan X, Xu Y. Protective role of lidocaine against cerebral ischemia-reperfusion injury: An in vitro study. Exp Ther Med 2021; 23:42. [PMID: 34849157 PMCID: PMC8613535 DOI: 10.3892/etm.2021.10964] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Accepted: 05/20/2020] [Indexed: 12/17/2022] Open
Abstract
Lidocaine, a local anesthetic, is a valuable agent for the treatment of neuronal ischemia/reperfusion (I/R) injury. The aim of the present study was to investigate the role of lidocaine in oxygen-glucose deprivation/reperfusion (OGD/R)-induced cortical neurons and explore the related molecular mechanisms. Cerebral cortical neurons were isolated from Sprague-Dawley rat embryos and stimulated with OGD/R to establish an in vitro I/R injury model. Subsequently, neuronal cell viability, cytotoxicity and apoptosis were evaluated by performing the MTT assay, lactate dehydrogenase (LDH) assay and flow cytometry, respectively. The results suggested that OGD/R exposure significantly decreased cerebral cortical neuron cell viability, accelerated LDH release and induced cell apoptosis compared with control neurons, indicating that cerebral I/R injury was stimulated by OGD/R treatment. Further investigation indicated that 10 µM lidocaine significantly enhanced neuronal cell viability, and reduced LDH release and neuronal cell apoptosis in OGD/R-exposed cells compared with the OGD/R + saline group, which indicated that lidocaine displayed neuroprotective effects against I/R damage. In addition, the findings of the present study suggested that OGD/R exposure significantly decreased Bcl-2 and Bcl-xl protein expression levels, but increased Bax protein expression levels, the Bax/Bcl-2 ratio and caspase-3 activity compared with control neurons. However, lidocaine reversed OGD/R-mediated alterations to apoptosis-related protein expression. Furthermore, the results of the present study indicated that lidocaine increased Wnt3a, β-catenin and cyclin D1 expression levels in OGD/R-exposed cells compared with the OGD/R + saline group, thus activating the Wnt/β-catenin signaling pathway. The findings of the present study suggested that lidocaine served a protective role in OGD/R-triggered neuronal damage by activating the Wnt/β-catenin signaling pathway; therefore, lidocaine may serve as a potential candidate for the treatment of cerebral I/R injury.

Effects of lanthanum nitrate on behavioral disorder, neuronal damage and gene expression in different developmental stages of Caenorhabditis elegans. Toxicology 2021; 465:153012. [PMID: 34718030 DOI: 10.1016/j.tox.2021.153012] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 10/20/2021] [Accepted: 10/22/2021] [Indexed: 11/17/2022]
Abstract
Rare earth elements (REEs) are widely used in the industry, agriculture, biomedicine, aerospace, etc, and have been shown to pose toxic effects on animals, as such, studies focusing on their biomedical properties are gaining wide attention. However, environmental and population health risks of REEs are still not very clear. Also, the REEs damage to the nervous system and related molecular mechanisms needs further research. In this study, the L1 and L4 stages of the model organism Caenorhabditis elegans were used to evaluate the effects and possible neurotoxic mechanism of lanthanum(III) nitrate hexahydrate (La(NO3)3·6H2O). For the L1 and L4 stage worms, the 48-h median lethal concentrations (LC50s) of La(NO3)3·6H2O were 93.163 and 648.0 mg/L respectively. Our results show that La(NO3)3·6H2O induces growth inhibition and defects in behavior such as body length, body width, body bending frequency, head thrashing frequency and pharyngeal pumping frequency at the L1 and L4 stages in C. elegans. The L1 stage is more sensitive to the toxicity of lanthanum than the L4 stage worms. Using transgenic strains (BZ555, EG1285 and NL5901), we found that La(NO3)3·6H2O caused the loss or break of soma and dendrite neurons in L1 and L4 stages; and α-synuclein aggregation in L1 stage, indicating that Lanthanum can cause toxic damage to dopaminergic and GABAergic neurons. Mechanistically, La(NO3)3·6H2O exposure inhibited or activated the neurotransmitter transporters and receptors (glutamate, serotonin and dopamine) in C. elegans, which regulate behavior and movement functions. Furthermore, significant increase in the production of reactive oxygen species (ROS) was found in the L4 stage C. elegans exposed to La(NO3)3·6H2O. Altogether, our data show that exposure to lanthanum can cause neuronal toxic damage and behavioral defects in C. elegans, and provide basic information for understanding the neurotoxic effect mechanism and environmental health risks of rare earth elements.

Abstract
Lanthanum nanoparticles are widely used in industry, agriculture, and biomedicine. Over 900 kg of lanthanum is annually released into the environment only in Europe, 50 times higher than the metals, mercury, and cadmium's environmental spread. Human health risk associated with long-term exposure to the abundant lanthanum nanoparticles is a concerning environmental issue. Due to lanthanum's ability to disrupt the main biological barriers and interrupt various cells' hemostasis, they seem to cause severe disruptions to various tissues. This review opens a new perspective regarding the cellular and molecular interaction of nanosized and ionic lanthanum with the possible toxicity on the nervous system and other tissues that would show lanthanum nanoparticles' potential danger to follow in toxicological science.

Association between exposure of light rare earth elements and outcomes of in vitro fertilization-embryo transfer in North China. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 762:143106.

Abstract
The adverse health effects of rare earth elements (REEs) on reproductive health remain a subject of debate, and few clinical observations are available. This study investigated the association between light REEs (LREEs) exposure and the outcome of in vitro fertilization-embryo transfer (IVF-ET). We recruited a total of 305 women undergoing IVF-ET in Beijing City and Shandong Province of northern China. Their demographic information and lifestyle characteristics were collected using questionnaires at enrollment. Fasting blood samples were collected on the day before the IVF-ET treatment cycle began. Serum concentrations of the LREEs of concern were analyzed using inductively coupled plasma-mass spectrometry, and four LREEs were measured with a high detection rate, including lanthanum (La), cerium (Ce), praseodymium (Pr), and neodymium (Nd). We found that a higher serum La concentration was associated with a 30% increased likelihood of clinical pregnancy failure [relative risk (RR) = 1.30, 95% confidence interval (CI): 1.00-1.67] and a 230% increased likelihood of preclinical spontaneous abortion (RR = 3.30, 95% CI: 1.57-6.94). There was a negative correlation between serum La concentration and the number of good-quality oocytes. For the other LREEs, no statistically significant associations were observed. We concluded that a high serum La concentration may have an adverse effect on IVF-ET outcomes.

Inducing red pigment and inhibiting citrinin production by adding lanthanum(III) ion in Monascus purpureus fermentation. Appl Microbiol Biotechnol 2021; 105:1905-1912.

Abstract
Monascus pigments (MPs) are widely used natural colorants in Asian countries. The problems of low extracellular red pigment (ERP) and high citrinin remain to be solved in Monascus pigment production. The effect of lanthanum(III) ion (LaCl3) on Monascus purpureus fermentation was investigated in this study. The yields of ERP and biomass respectively reached maxima of 124.10 U/mL and 33.10 g/L by adding 0.4 g/L La3+ on the second day in the total 8-day fermentation; simultaneously, citrinin was decreased by 59.93% and 38.14% in the extracellular and intracellular fractions, respectively. Reactive oxygen species (ROS) levels were obviously improved by La3+ treatment, while the activities of catalase (CAT) and superoxide dismutase (SOD) were increased compared with the control. The ratio of unsaturated/saturated fatty acids in mycelia was increased from 2.94 to 3.49, indicating that the permeability and fluidity of the cell membrane were enhanced under La3+ treatment. Gene expression analysis showed that the relative expression levels of Monascus pigment synthesis genes (pksPT, mppB, mppD, MpFasB2, and MpPKS5) were significantly upregulated by La3+ treatment, and in contrast, the relative expression levels of citrinin synthesis genes (ctnA, pksCT and mppC) were markedly downregulated. This work confirmed that LaCl3 possesses the potential to induce red pigment biosynthesis and inhibit citrinin production in M. purpureus fermentation. KEY POINTS: • La3+ induced red pigment and inhibited citrinin production in Monascus fermentation. • La3+ regulated genes expression up for Monascus pigment and down for citrinin. • La3+ increased the UFAs in cell membrane to enhance the permeability and fluidity.

Abstract
BACKGROUND The widespread exploitation and application of rare earth elements (REE) have led to the risk of human exposure and might result in the adverse health effect on pregnant women. However, no epidemiological studies have explored the associations between prenatal REE exposure and premature rupture of membranes (PROM). OBJECTIVE We aimed to investigate the associations of maternal urinary REE levels with the risk of PROM. METHODS A total of 4897 mother-newborn pairs were recruited from a birth cohort study in Wuhan, China. Urinary concentrations of REE were measured by inductively coupled plasma mass spectrometry (ICP-MS). The associations of prenatal REE exposure with PROM were evaluated using logistic regression models. False discovery rate (FDR) was applied to adjust for multiple testing. Weighted quantile sum (WQS) regression was used to estimate the association of urinary REE mixture with PROM. RESULTS With one unit increase (μg/g creatinine) in natural log-transformed urinary REE levels (Ce, Yb, La, Pr, Nd, Eu, Gd, Dy, Ho, Er, Tm), the adjusted ORs (95% CIs) for the PROM were from 1.143 (1.078, 1.211) to 1.317 (1.223, 1.419), and the associations were still observed after FDR adjustment (all PFDRs < 0.05). The associations were stronger among male infants than female infants. Furthermore, the urinary REE mixture was also associated with the risk of PROM, a quartile increase in the WQS index of REE resulted in ORs (95% CI) for the PROM of 1.494 (1.356, 1.645) in the adjusted model. CONCLUSIONS Our findings suggested that prenatal exposure to REE (Ce, Yb, La, Pr, Nd, Eu, Gd, Dy, Ho, Er, and Tm) and REE mixture were associated with the increased risk of PROM. Further studies from different populations are needed to confirm the associations and to explore the mechanisms.

Abstract
In the last decades, there is an increasing inclusion of various trace metals and metalloids such as thallium, tellurium and rare earth elements (REEs; lanthanides, scandium, and yttrium) in the composition and production of alloys, in agricultural and medicinal applications, as well as in the manufacturing of hi-tech products. All these activities have led to an accumulation of the aforementioned elements both in soil and water bodies and consequently in the food chain, through discharges from mining and mineral processing, liquid industrial waste or disposal of urban and industrial products. It has been demonstrated that chronic exposure to some of these elements, even at low doses, might lead to a wide range of adverse health effects, even from the early stages of life, such as neurotoxicity, neurodevelopmental toxicity and hepatic alterations. Particularly in children, there have been studies suggesting that some of these elements might negatively affect the children's spatial learning and memory ability indirectly. Such effects are triggered by processes like the production of reactive oxygen species (ROS), lipid peroxidation and modulation of antioxidant activities. Nevertheless, the limited data from toxicological studies and their so-far naturally low occurrence levels in the environment acted as a deterrent in measuring their concentrations during routine analyses of metals in foodstuff. Thus, it is important to collect information on their occurrence data both in adults and in children's daily diet. This review sumrises the current knowledge on the concentration of these elements, in plant-based food products to identify whether a potential health risk occurs. As side projects, this Fellowship provided hands-on training on the evaluation of new biocides application and participation in the given advice to the Danish Food and Veterinary Administration, Danish Environmental Protection Agency, the Danish Medical Agency and the European Chemicals Agency.

Lanthanum Chloride Causes Neurotoxicity in Rats by Upregulating miR-124 Expression and Targeting PIK3CA to Regulate the PI3K/Akt Signaling Pathway. BIOMED RESEARCH INTERNATIONAL 2020; 2020:5205142. [PMID: 32461997 PMCID: PMC7222569 DOI: 10.1155/2020/5205142] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 02/15/2020] [Accepted: 03/02/2020] [Indexed: 12/18/2022]
Abstract
Background Lanthanum (La) exposure can cause central nervous system (CNS) damage and dysfunction in children, seriously affecting intellectual development. miR-124 plays an important role in the development of the nervous system. We exposed rats to a La environment then observed the rats' learning and memory damage and neurotoxicity and the relationship with miR-124. Methods Rats were exposed to LaCl3 via drinking water. The rats' offspring were exposed to LaCl3 from their mother before weaning, then from La water for 28 days. A Morris water maze was used to observe spatial memory capabilities. H&E staining and TUNEL assays were used to observe pathological changes and apoptosis in the hippocampus. miR-124 was detected by RT-qPCR, and its targeting was confirmed by luciferase assay. The HT22 cell line was cultured with LaCl3 and treated with miR-124 mimics or inhibitors; then, expression of PI3K/Akt-related proteins was detected by western blot. Results La exposure can lead to impaired learning and memory ability in offspring. Offspring with La accumulations in the hippocampus showed severe damage, disordered cells, and increased neurocyte apoptosis. In vitro, the postsynaptic density protein 95 was downregulated under La exposure and apoptosis increased. This effect of La can be attenuated by miR-124 inhibitors and enhanced by miR-124 mimics. LaCl3 exposure increased miR-124 expression and targeting on PIK3CA, downregulating PI3K, p-Akt, and p-NF-κB p65. Conclusion La causes neurotoxicity by upregulating miR-124 expression and targeting PIK3CA through the PI3K/Akt signaling pathway.

Abstract
Lanthanum (La) is a natural rare earth element. It has neurotoxic effects which can impair learning and memory in humans. However, its mechanism of neurotoxicity is unclear. Learning and memory are coordinated by dendritic spines which form tiny protruding structures on the dendritic branches of neurons. This study investigated the effect of LaCl3 exposure to pregnant and lactating rats on the offspring rats' learning and memory ability. In this study, rats were divided into 4 groups and given distilled water solution containing 0%, 0.125%, 0.25%, 0.5% LaCl3, respectively, and this was done from conception to the end of the location. The effects of LaCl3 on spatial learning and memory ability in offspring rats and in the development of dendritic spines in CA1 pyramidal cells were investigated. The results showed that LaCl3 impaired spatial learning and memory ability in offspring rats, and decreased dendritic spine density during development. In addition, LaCl3 can affect the expression of CaMKII, miRNA132, p250GAP, Tiam1, PARD3, and down-regulated the activation of Rac1 which led to a decrease in the expression of Rac1/PAK signaling pathway and downstream regulatory proteins Cortactin and actin-related protein 2/3 complex (Arp2/3 complex). This study indicated that the learning and memory impairment and the decrease of dendritic spine density in the offspring of LaCl3 exposure may be related to the down-regulation of the Rac1/PAK signaling pathway regulated by Tiam1 and p250GAP.

Abstract
Recently, chemical compounds containing lanthanides were used in various fields of biology and medicine. It has been described that such compounds can be applied in scanning electron microscopy (SEM) to increase the contrast and simplify the sample preparation process due to the process of replacing calcium with lanthanides in cell. However cell death by different mechanisms under influence of lanthanides seems possible. Here, we described that mummification process is a cell death physiologically realized in time: some time after lanthanide contrasting, the cell remains metabolically active and is able to biochemically transform neodymium-containing contrast, oxidize it and form large agglomerates. A distinctive feature of mummification induced by neodymium-containing contrast (NCC) is the formation of a high-rigid oxygen-containing "shield" on the surface of a neutrophil granulocyte.

Abstract
Lanthanum (La) can accumulate in the brain and impair learning and memory. However, the underlying mechanism of La-induced neurotoxicity has remained elusive. Under physiological conditions, it has been reported that moderately excitatory astrocytes play an important role in the regulation of neuronal signals and synaptic plasticity. However, under pathological conditions, overly excitatory astrocytes can release excess excitatory transmitters, such as glutamate (Glu) and d-serine, and induce the over-activation of NMDA receptors (NMDAR) in neurons, ultimately leading to neuronal excitotoxicity. To date, limited work has been performed with respect to whether La can induce neuronal excitotoxicity by inducing astrocytes to become overexcited. In this study, in vitro models of primary culture rat cortical astrocytes and neurons were established. First, the astrocytes were treated with 0.125 mM, 0.25 mM and 0.5 mM lanthanum chloride (LaCl3) for 24 h, and the supernatants were collected as a conditioned medium (CM) which is denoted as CM (La3+); then, the neurons were treated with CM (La3+) for 48 h. The results illustrate that LaCl3 treatment significantly upregulated the mRNA and protein expression levels of metabotropic glutamate receptor 5 (mGLUR5), phospholipase C (PLC), connexin 43 (Cx43) and Cx30, increased the concentrations of inositol trisphosphate (IP3) and [Ca2+]i, and promoted the synthesis and release of Glu and d-serine in astrocytes. Moreover, the CM (La3+) could increase the mRNA and protein expression levels of NMDAR subunits (NR1, NR2A, NR2B), the concentration of [Ca2+]i and the rate of apoptosis in neurons. Furthermore, after removal of La, CM (La-free) had a similar effect on neurons which could be antagonized by MK-801, DCKA and DAAO. These results suggest that the neuron apoptosis induced by La is closely related to the excessive release of Glu and d-serine from overly excitatory astrocytes.

Abstract
Trivalent lanthanide and actinide can strongly bind to calmodulin (CaM). The global structure of Ln/An-bound CaM were found to be similar to Ca-CaM but the local environment around Ln/An is distorted giving less structural rigidity to Ln/An-CaM.

Abstract
During the pathogenesis of gastric cancer, Akt signaling is considered as a pivotal inducer of gastric cancer development. Here we report the identification of anticancer activities of deguelin, a natural agent that inhibits Akt signaling. When applied to MGC-803 and MKN-45 cells, deguelin suppressed the proliferation and arrested cell cycle by p21-mediated inhibition of cyclin E. We further present in vitro evidence that deguelin promoted apoptosis of cancer cells by decreasing the phospho-Akt signaling and affecting expression of the apoptosis-associated genes Bax and Bcl-2. Additionally, deguelin was found to suppress the migration and invasion of gastric cancer cells. Taken together, these results indicated that deguelin exerted anticancer activity of human gastric cancer MGC-803 and MKN-45 cells in vitro.

Abstract
Lanthanum exerts adverse effects on the central nervous system. However, the mechanism underlying these adverse effects has not been clarified. It is known that oxidative stress plays an important role in neurological injuries induced by harmful factors. Nuclear factor erythroid 2-related factor (Nrf2) is very important in the response to oxidative stress in tissues and cells. The purpose of this study was to explore the effect of lanthanum chloride (LaCl3 ) on the spatial learning and memory of rats and to determine whether the Nrf2/antioxidant response element pathway acts in the hippocampus. Four groups of Wistar rats were exposed to 0 mM, 9 mM, 18 mM or 36 mM LaCl3 through their drinking water from the day of birth to 2 months after weaning. The results showed that LaCl3 impaired the spatial learning and memory of the rats, damaged the neuronal ultrastructure, increased reactive oxygen species levels and significantly down-regulated Nrf2 as well as the mRNA and protein expression of Nrf2-regulated genes, including NADP(H): dehydrogenase quinone 1, haeme oxygenase-1, superoxide dismutase 2, glutathione peroxidase 1, glutathione-S-transferase, γ-glutamine cysteine synthase and glutathione reductase, in the hippocampus. This study suggests that LaCl3 can impair the spatial learning and memory of rats, possibly by perturbing the Nrf2/antioxidant response element signalling pathway.

Abstract
Deguelin, a naturally occurring rotenoid of the flavonoid family, is known to be an Akt inhibitor, to have chemopreventive activities and anti-tumor effect on several cancers. In this study, investigation to elucidate the effect of deguelin on apoptotic pathways in human lung cancer cells and on the anti-tumor effect in lung cancer xenograft nu/nu mice was performed. In vitro studies, found that deguelin induced cell morphological changes, and decreased the percentage of viability through the induction of apoptosis in H460 lung cancer cells. Deguelin triggered apoptosis in H460 cells was also confirmed by DAPI staining, DNA gel electrophoresis, and Annexin V-FITC staining and these effects are dose-dependent manners. It was also found that deguelin promoted the Ca2+ production and activation of caspase-3 but decreased the level of ΔΨm in H460 cells. Western blots indicated that the protein levels of cytochrome c, AIF, and pro-apoptotic Bax and Bak protein were increased, but the anti-apoptotic Bcl-2 and Bcl-x were decreased that may have led to apoptosis in H460 cells after exposure to deguelin. It was also confirmed by confocal laser microscope examination that deguelin promoted the release of AIF from mitochondria to cytosol. In vivo studies, found that in immunodeficient nu/nu mice bearing H460 tumor xenografts showed that the deguelin significantly suppressed tumor growth. Deguelin might be a potential therapeutic agent for the treatment of lung cancer in the future. This finding might fully support a critical event for deguelin via induction of apoptotic cell death and H460 tumor xenografts model against human lung cancer. © 2015 Wiley Periodicals, Inc.

Abstract
Bcl-2, the first gene shown to be involved in apoptosis, is a potent regulator of cell survival and known to have protective effects against a variety of age-related diseases. However, the possible relationship between hearing and Bcl-2 expression in the cochlea or auditory cortex of C57BL/6 mice, a mouse model of age-related hearing loss, is still unknown. Using RT-PCR, immunohistochemistry, and Western blot analysis, our results show that Bcl-2 is strongly expressed in the inner hair cells and spiral ganglion neurons of young mice. In addition, moderate Bcl-2 expression is also detected in the outer hair cells and in the neurons of the auditory cortex. A significant reduction of Bcl-2 expression in the cochlea or auditory cortex is also associated with elevated hearing thresholds and hair cell loss during aging. The expression pattern of Bcl-2 in the peripheral and central auditory systems suggests that Bcl-2 may play an important role in auditory function serving as a protective molecule against age-related hearing loss.

Abstract
The increasing use of rare-earth elements (REE) and their compounds has led to their accumulation in the environment and has raised concern about their safety. The toxic effects of REE such as lanthanum are largely unknown; genotoxicity studies have been limited and results are controversial. We evaluated the genotoxicity of lanthanum nitrate (La(NO3)3) in several in vitro and in vivo tests, including bacterial reverse mutation assay (Ames test), mouse bone marrow micronucleus assay, and chromosome aberration assay. La(NO3)3 was not mutagenic in the Ames test. La(NO3)3 did not increase the frequencies of bone marrow micronuclei or chromosome aberration in the mouse after repeated treatments at oral doses up to 735 (females) and 855mg/kg (males). The compound did not increase the frequency of chromosome aberrations in CHO cells in vitro. These results indicate that lanthanum is not a genotoxic hazard.

Abstract
Lanthanide elements have been documented to possess various biologic effects, and their compounds have been studied intensely for their anti-cancer potential. However, the underlying mechanisms remain largely unknown. In the present study, we propose that the levels of proliferation and apoptosis related microRNAs (miRNAs), let-7a and miR-34a, which mediate the apoptosis of cervical cancer cells, can be affected by the lanthanum ion. Our data showed that LaCl3 inhibited the proliferation and induced the apoptosis of cervical cancer cells both in vivo and in vitro by regulating let-7a, miR-34a and their downstream genes. This study provides novel evidence demonstrating that the anticancer mechanism of lanthanum chloride is partially attributed to miRNAs regulation and establishes an experimental basis for the clinical application of lanthanum chloride as an anti-cancer drug.

Abstract
Lanthanum (La) appears to impair learning and memory and increase the toxicity of excitatory amino acids in the central nervous system. The mechanism underlying excitotoxicity induced by La is still unclear. The purpose of this study was to investigate the hippocampal impairment of La exposure and possible mechanism involving the glutamate-nitric oxide (NO)-3'-5'-cyclic guanosine monophosphate (cGMP) pathway. In this study, lactating rats were exposed to 0, 0.25, 0.50, and 1.0% lanthanum chloride (LaCl3) in drinking water, respectively. Their offsprings were exposed to LaCl3 by parental lactation and then administrated with 0, 0.25, 0.50, and 1.0% LaCl3 in drinking water for 1 month. The results showed that La exposure impaired the neuronal ultrastructure and significantly increased the glutamate level, intracellular calcium ion concentrations, and NR1 and NR2B expression in the hippocampi. La exposure significantly enhanced messenger RNA expression and activity levels of inducible NO synthase and increased NO and cGMP levels in the hippocampi in a dose-dependent manner. These results indicate that the mechanism underlying excitotoxicity induced by La is possibly due to alterations of the glutamate-NO-cGMP signaling pathway in the hippocampus. The study provides new findings that may help prevent and improve treatments for La-induced neurotoxicity.

Abstract
In the recent decades, rare earth elements (REE) have undergone a steady spread in several industrial and medical applications, and in agriculture. Relatively scarce information has been acquired to date on REE-associated biological effects, from studies of bioaccumulation and of bioassays on animal, plant and models; a few case reports have focused on human health effects following occupational REE exposures, in the present lack of epidemiological studies of occupationally exposed groups. The literature is mostly confined to reports on few REE, namely cerium and lanthanum, whereas substantial information gaps persist on the health effects of other REE. An established action mechanism in REE-associated health effects relates to modulating oxidative stress, analogous to the recognized redox mechanisms observed for other transition elements. Adverse outcomes of REE exposures include a number of endpoints, such as growth inhibition, cytogenetic effects, and organ-specific toxicity. An apparent controversy regarding REE-associated health effects relates to opposed data pointing to either favorable or adverse effects of REE exposures. Several studies have demonstrated that REE, like a number of other xenobiotics, follow hormetic concentration-related trends, implying stimulatory or protective effects at low levels, then adverse effects at higher concentrations. Another major role for REE-associated effects should be focused on pH-dependent REE speciation and hence toxicity. Few reports have demonstrated that environmental acidification enhances REE toxicity; these data may assume particular relevance in REE-polluted acidic soils and in REE mining areas characterized by concomitant REE and acid pollution. The likely environmental threats arising from REE exposures deserve a new line of research efforts.

Abstract
Environmental pollution from lanthanides (Ln) has been recognized as a major problem due to a grab exploitation of Ln mine in China. Exposure to Ln has been demonstrated to cause the nephrotoxicity, very little is known about the mechanism of oxidative damage to kidney in animals. In order to understand Ln-induced nephrotoxicity, various biochemical and chemical parameters were assayed in mouse kidney. Intragastric exposures of LaCl₃, CeCl₃, and NdCl₃ at doses of 2, 5, and 10 mg kg(-1) BW for 90 consecutive days caused nephritis or epithelial cell necrosis and oxidative stress to kidney. An increase in coefficients of the kidney, La, Ce, and Nd accumulation and histopathological changes in the kidney could be observed, followed by increased reactive oxygen species production and peroxidation levels of lipid, protein and DNA, and decreased activities of superoxide dismutase, catalase, glutathione-S-transferase and glutathione reductase as well as antioxidants such as glutathione, ascorbic acid and thiol contents. Furthermore, La, Ce, and Nd significantly suppressed expression of genes and proteins of these antioxidative enzymes in mouse kidney. In addition, kidney functions were disrupted, including an increase of the creatinine, and reductions of uric acid, urea nitrogen, calcium and phosphonium. These findings suggest that nephritis generation or epithelial cell necrosis in mice following exposure to Ln is closely associated with oxidative stress. Of these damages, the most severe was in the Ce(3+)-exposed kidneys, next in the Nd(3+)-exposed kidneys, and the least in the La(3+)-exposed kidneys, which may be attributed to the 4f electron of Ln.
