Modular flow chamber for engineering bone marrow architecture and function

Publication date: November 2017
Source:Biomaterials, Volume 146
Author(s): Christian A. Di Buduo, Paolo M. Soprano, Lorenzo Tozzi, Stefania Marconi, Ferdinando Auricchio, David L. Kaplan, Alessandra Balduini
The bone marrow is a soft, spongy, gelatinous tissue found in the hollow cavities of flat and long bones that support hematopoiesis in order to maintain the physiologic turnover of all blood cells. Silk fibroin, derived from Bombyx mori silkworm cocoons, is a promising biomaterial for bone marrow engineering, because of its tunable architecture and mechanical properties, the capacity of incorporating labile compounds without loss of bioactivity and demonstrated ability to support blood cell formation. In this study, we developed a bone marrow scaffold consisting of a modular flow chamber made of polydimethylsiloxane, holding a silk sponge, prepared with salt leaching methods and functionalized with extracellular matrix components. The silk sponge was able to support efficient platelet formation when megakaryocytes were seeded in the system. Perfusion of the chamber allowed the recovery of functional platelets based on multiple activation tests. Further, inhibition of AKT signaling molecule, which has been shown to be crucial in regulating physiologic platelet formation, significantly reduced the number of collected platelets, suggesting the applicability of this tissue model for evaluation of the effects of bone marrow exposure to compounds that may affect platelet formation. In conclusion, we have bioengineered a novel modular system that, along with multi-porous silk sponges, can provide a useful technology for reproducing a simplified bone marrow scaffold for blood cell production ex vivo.

Live cell imaging of mouse intestinal organoids reveals heterogeneity in their oxygenation

Publication date: November 2017
Source:Biomaterials, Volume 146
Author(s): Irina A. Okkelman, Tara Foley, Dmitri B. Papkovsky, Ruslan I. Dmitriev
Intestinal organoids are widely applied in stem cell research, regenerative medicine, toxicology, pharmacology, and host-microbe interactions research. The variability of oxidative metabolism for stem and differentiated cell types constituting organoid is known to be important but so far it has not been studied in details. Here, we report the use of live cell microscopy of oxygen via the phosphorescence lifetime imaging microscopy (PLIM) method to address the oxygenation and variability of aerobic metabolism of individual organoids in the culture. Using the cell-penetrating phosphorescent O2-sensitive probe, we found inhomogeneous O2 distribution in live organoids, with areas of relatively high oxygenation (up to 73 μM in organoid compared to an average 40 μM O2) and trans-epithelial O2 microgradients (up to 0.6–0.83 μM/μm). We also demonstrated that intestinal organoid culture consists of units with different respiration activity and oxygenation (from 27 to 92 μM, equal to 2.8–9.7% O2), depending on age of the culture and drug treatment. Collectively, our results indicate that ignoring the metabolic heterogeneity of organoid culture can be critical for proper data interpretation. The live cell imaging PLIM method demonstrates a clear advantage of using individual organoids as separate experimental units rather than 'bulk' organoid cultures.

Cuprous oxide nanoparticles trigger ER stress-induced apoptosis by regulating copper trafficking and overcoming resistance to sunitinib therapy in renal cancer

Publication date: November 2017
Source:Biomaterials, Volume 146
Author(s): Qiwei Yang, Ye Wang, Qing Yang, Yi Gao, Xiaopeng Duan, Qingcheng Fu, Chuanmin Chu, Xiuwu Pan, Xingang Cui, Yinghao Sun
While the current standard first-line treatment for advanced renal cell carcinoma (RCC) is sunitinib, patients inevitably develop resistance to this drug. However, the rapid development of nanotechnology has provided emerging techniques for the treatment of advanced tumours, including RCC. In our previous research, cuprous oxide nanoparticles (CONPs) showed ideal anti-tumour effects and low systemic toxicity. While many inorganic nanomedicines, including CONPs, have similar pharmacological effects, their detailed mechanisms remain unknown. Copper chaperone proteins, which regulate the endocellular dosage and transport of copper, also play crucial roles in the progression of cancer. In this research, we discovered that CONPs can disrupt copper transportation by regulating the copper chaperone proteins ATOX1 and CCS in RCC cells and induce endoplasmic reticulum (ER) stress in vitro and in vivo by promoting the accumulation of intracellular calcium and reactive oxygen species (ROS). Furthermore, CONPs can initiate ER- and mitochondrial-dependent apoptosis by activating caspase-3, caspase-9 and caspase-12. In addition, CONPs downregulate the expression of AXL, MET, AKT, and ERK to recover sunitinib responsiveness in RCC cells with sunitinib resistance (SR) and may therefore facilitate the development of promising new pathways to treat patients with acquired SRRCC.

Infectious diseases are a major global threat that accounts for one of the leading causes of global mortality and morbidity. Prompt diagnosis is a crucial first step in the management of infectious threats, which aims to quarantine infected patients to avoid contacts with healthy individuals and deliver effective treatments prior to further spread of diseases. This review article discusses current advances of diagnostic systems using colloidal nanomaterials (e.g., gold nanoparticles, quantum dots, magnetic nanoparticles) for identifying and differentiating infectious pathogens. The challenges involved in the clinical translation of these emerging nanotechnology based diagnostic devices will also be discussed.

MicroRNAs in thyroid development, function and tumorigenesis

Publication date: 15 November 2017
Source:Molecular and Cellular Endocrinology, Volume 456
Author(s): Cesar Seigi Fuziwara, Edna Teruko Kimura
MicroRNAs (miRNAs) are important post-transcriptional regulators of gene expression that modulate the vast majority of cellular processes. During development, the correct timing and expression of miRNAs in the tissue differentiation is essential for organogenesis and functionality. In thyroid gland, DICER and miRNAs are necessary for accurately establishing thyroid follicles and hormone synthesis. Moreover, DICER1 mutations and miRNA deregulation observed in human goiter influence thyroid tumorigenesis. The thyroid malignant transformation by MAPK oncogenes is accompanied by global miRNA changes, with a marked reduction of "tumor-suppressor" miRNAs and activation of oncogenic miRNAs. Loss of thyroid cell differentiation/function, and consequently iodine trapping impairment, is an important clinical characteristic of radioiodine-refractory thyroid cancer. However, few studies have addressed the direct role of miRNAs in thyroid gland physiology. Here, we focus on what we have learned in the thyroid follicular cell differentiation and function as revealed by cell and animal models and miRNA modulation in thyroid tumorigenesis.

Regulation of body growth by microRNAs

Publication date: 15 November 2017
Source:Molecular and Cellular Endocrinology, Volume 456
Author(s): Julian C. Lui
Regulation of body growth remains a fascinating and unresolved biological mystery. One key component of body growth is skeletal and longitudinal bone growth. Children grow taller because their bones grew longer, and the predominant driver of longitudinal bone growth is a cartilaginous structure found near the ends of long bone named the growth plate. Numerous recent studies have started to unveil the importance of microRNAs in regulation of growth plate functions, therefore contributing to regulation of linear growth. In addition to longitudinal growth, other organs in our body need to increase in size and cell number as we grow, and the regulation of organ growth involves both systemic factors like hormones; and other intrinsic mechanisms, which we are just beginning to understand. This review aims to summarize some recent important findings on how microRNAs are involved in both of these processes: the regulation of longitudinal bone growth, and the regulation of organs and overall body growth.

MicroRNAs in parathyroid physiopathology

Publication date: 15 November 2017
Source:Molecular and Cellular Endocrinology, Volume 456
Author(s): V. Vaira, C. Verdelli, I. Forno, S. Corbetta
Parathyroid glands regulate calcium homeostasis through synthesis and secretion of parathormone (PTH). They sense the extracellular calcium concentration through the G-protein coupled calcium sensing receptor (CASR) and release PTH in order to preserve calcium concentration in the physiological range. Tumors of the parathyroid glands are common endocrine neoplasia associated with primary or secondary/tertiary hyperparathyroidisms. Small non-coding RNAs are regulators of gene expression able to modulate hormone synthesis, hormone release and endocrine cell proliferation. In this scenario, microRNA (miRNA) expression profiles have been investigated in parathyroid tumors, while miRNAs are involved in hypocalcemia and uremia-induced PTH release from normal parathyroid cells. Here we reviewed data about the role of miRNAs in the regulation of: 1) PTH synthesis and secretion; 2) CASR expression; 3) parathyroid cell tumorigenesis. Though studies about miRNAs in parathyroid gland pathophysiology are limited, they contribute in elucidating regulatory pathways involved in PTH release and parathyroid cell tumorigenesis.

Small non-coding RNAs-based bone regulation and targeting therapeutic strategies

Publication date: 15 November 2017
Source:Molecular and Cellular Endocrinology, Volume 456
Author(s): Ying Yang, Sijie Fang
Small non-coding RNAs, which are 20–25 nucleotide ribonucleic acids, have emerged as an important transformation in the biological evolution over almost three decades. microRNAs (miRNAs) and short interfering RNAs (siRNAs) are two significant categories of the small RNAs that exert important effects on bone endocrinology and skeletology. Therefore, clarifying the expression and function of these important molecules in bone endocrine physiology and pathology is of great significance for improving their potential therapeutic value for metabolism-associated bone diseases. In the present review, we highlight the recent advances made in understanding the function and molecular mechanism of these small non-coding RNAs in bone metabolism, especially their potentially therapeutic values in bone-related diseases.

The role of microRNAs in the pathophysiology of adrenal tumors

Publication date: 15 November 2017
Source:Molecular and Cellular Endocrinology, Volume 456
Author(s): Nunki Hassan, Jing Ting Zhao, Stan B. Sidhu
MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression in a sequence-specific manner. Due to its association with an assortment of diseases, miRNAs have been extensively studied in the last decade. In this review, the current understanding of the role of miRNAs in the pathophysiology of adrenal tumors is discussed. The recent contributions of high-throughput miRNA profiling studies have identified miRNAs that have functional and molecular roles in adrenal tumorigenesis. With respect to the biological heterogeneity of adrenal tumors and the limitations of the current treatments, an improved understanding of miRNAs may hold potential diagnostic and therapeutic value to facilitate better clinical management.

Since the presence of microRNAs was first observed in normal pituitary, the majority of scientific publications addressing their role and the function of microRNAs in the pituitary have been based on pituitary tumor studies. In this review, we briefly describe the involvement of microRNAs in the synthesis of pituitary hormones and we present a comprehensive inventory of microRNA suppressors and inducers of pituitary tumors. Finally, we summarize the functional role of microRNAs in tumorigenesis, progression and aggressiveness of pituitary tumors, mechanisms contributing to the regulation (transcription factors, genomic modifications or epigenetic) or modulation (pharmacological treatment) of microRNAs in these tumors, and the interest of thoroughly studying the expression of miRNAs in body fluids.

ETS transcription factor family member GABPA contributes to vitamin D receptor target gene regulation

Publication date: Available online 11 September 2017
Source:The Journal of Steroid Biochemistry and Molecular Biology
Author(s): Sabine Seuter, Antonio Neme, Carsten Carlberg
Binding motifs of the ETS-domain transcription factor GABPA are found with high significance below the summits of the vitamin D receptor (VDR) cistrome. VDR is the nuclear receptor for the biologically most active vitamin D metabolite 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3). In this study, we determined the GABPA cistrome in THP-1 human monocytes and found that it is comprised of 3822 genomic loci, some 20% of which were modulated by 1,25(OH)2D3. The GABPA cistrome showed a high overlap rate with accessible chromatin and the pioneer transcription factor PU.1. Interestingly, 23 and 12% of persistent and transient VDR binding sites, respectively, co-localized with GABPA, which is clearly higher than the rate of secondary VDR loci (4%). Some 40% of GABPA binding sites were found at transcription start sites, nearly 100 of which are of 1,25(OH)2D3 target genes. On 593 genomic loci VDR and GABPA co-localized with PU.1, while only 175 VDR sites bound GABPA in the absence of PU.1. In total, VDR sites with GABPA co-localization may control some 450 vitamin D target genes. Those genes that are co-controlled by PU.1 preferentially participate in cellular and immune signaling processes, while the remaining genes are involved in cellular metabolism pathways. In conclusion, GABPA may contribute to differential VDR target gene regulation.

Promotional effect of rare earth-doped manganese oxides supported on activated semi-coke for selective catalytic reduction of NO with NH 3

Abstract

A composite catalyst for the selective catalytic reduction (SCR) of NO_x with NH₃ is investigated, in which the rare earth (RE, including La, Ce, Pr, and Nd) is doped into manganese oxides supported on activated semi-coke (MnO_x/ASC) via hydrothermal method at the molar ratio of Mn:RE = 1:5. It is evidenced that the addition of RE at a rather low molar ratio can enhance the catalytic activity of MnO_x/ASC. The catalyst with a Mn:Ce molar ratio of 10:1 yields an over 90% NO_x removal efficiency in the temperature range of 150–250 °C. An approximate 100% NO conversion and 95% N₂ selectivity are achieved at about 200 °C. The catalysts are characterized by N₂ physisorption, X-ray powder diffraction (XRD), scanning electron microscope (SEM), hydrogen temperature-programmed reduction (H₂-TPR) and X-ray photoelectron spectroscopy (XPS). The results indicated that the Ce additive is conducive to the NO_x adsorption and then accelerates the SCR reaction due to the formation of more chemisorbed oxygen (O_β), which is favored during the oxidation of NH₃ and NO. Moreover, the in situ diffused reflectance infrared Fourier transform spectroscopy (DRIFTS) results confirm that the Ce additive on MnO_x/ASC catalyst could provide more active Brønsted acid sites, which eventually contributes to the SCR reaction. The generation of ad-NH₄⁺ and nitrite species is proved to play the crucial role in the promotional effect of RE addition.

Childhood adversity predicts reduced physiological flexibility during the processing of negative affect among adolescents with major depression histories

Publication date: Available online 11 September 2017
Source:International Journal of Psychophysiology

BackgroundAdversity during early development has been shown to have enduring negative physiological consequences. In turn, atypical physiological functioning has been associated with maladaptive processing of negative affect, including its regulation. The present study therefore explored whether exposure to adverse life events in childhood predicted maladaptive (less flexible) parasympathetic nervous system functioning during the processing of negative affect among adolescents with depression histories.MethodsAn initially clinic-referred, pediatric sample (N=189) was assessed at two time points. At Time 1, when subjects were 10.17years old (SD=1.42), on average, and were depressed, parents reported on adverse life events the offspring experienced up to that point. At Time 2, when subjects were 17.18years old (SD=1.28), and were remitted from depression, parents again reported on adverse life events in their offspring's lives for the interim period. At time 2, subjects' parasympathetic nervous system functioning (quantified as respiratory sinus arrhythmia) also was assessed at rest, during sad mood induction, and during instructed mood repair.ResultsExtent of adverse life events experienced by T1 (but not events occurring between T1 and T2) predicted less flexible RSA functioning 7years later during the processing of negative affect. Adolescents with more extensive early life adversities exhibited less vagal withdrawal following negative mood induction and tended to show less physiological recovery following mood repair.ConclusionsEarly adversities appear to be associated with less flexible physiological regulatory control during negative affect experience, when measured later in development. Stress-related autonomic dysfunction in vulnerable youths may contribute to the unfavorable clinical prognosis associated with juvenile-onset depression.
