Abstract
BACKGROUND Insufficient sleep adversely affects energy homeostasis by decreasing leptin levels. The underlying physiological mechanisms; however, remain unclear. Circulating leptin is well described to be regulated by its soluble receptor (sOB-R). Intriguingly, the impact of short sleep duration on sOB-R levels has never been characterized. AIM In this study, we investigated, for the first time, the variation of sOB-R levels and its temporal relationship with circulating leptin upon acute sleep restriction. METHODS Five adult females were maintained on an 8-hour sleep schedule (bedtime at 00:00) for 1 week before restricting their sleep to 4.5 h (bedtime at 03:30) on 2 consecutive nights. Balanced meals were scheduled to specific hours and sleep was objectively measured. Four-hour blood samples were regularly collected during waking hours between 08:00 and 00:00. RESULTS Sleep restriction resulted in lower leptin (20.9 ± 1.7 vs 25.7 ± 1.7 ng/ml) and higher sOB-R concentrations (24.4 ± 1.2 vs 19.8 ± 1.6 ng/ml). Neither the discordant temporal relationship nor the pattern of leptin and sOB-R were altered in response to sleep restriction. CONCLUSION Our results suggest that sleep restriction may modulate circulating leptin levels and possibly metabolism via upregulating its soluble receptor. This observation may have valuable therapeutic implications when considering sOB-R as a potential target during the management of metabolic disturbances.

Abstract
BACKGROUND Breast cancer, the deadliest disease affecting women globally, exhibits heterogeneity with distinct molecular subtypes. Despite advances in cancer therapy, the persistence of high mortality rates due to chemotherapy resistance remains a major challenge. Lipoic acid (LA), a natural antioxidant, has proven potent anticancer properties. Yet, the impact of LA on microRNA (miRNA) expression profile in breast cancer remains unexplored. AIM The aim of this study was to unravel the effect of LA on miRNA expression profiles in different breast cancer cell lines. METHODS The MiRCURY LNA miRNA miRNome qPCR Panel was used to compare the miRNA signature in MDA-MB-231 and MCF-7 cells treated or not with LA. RESULTS We identified six upregulated and six downregulated miRNAs in LA-treated MDA-MB-231 cells and 14 upregulated and four downregulated miRNAs in LA-treated MCF-7 cells compared to control cells. KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis revealed that the deregulated miRNAs could alter different signaling cascades including FoxO, P53 and Hippo pathways. CONCLUSION The outcome of this study provides further insights into the molecular mechanisms underlying the therapeutic benefit of LA. This in turn could assist the amelioration of LA-based anticancer therapies.

Abstract
Coronavirus disease 2019 (COVID-19), a serious infectious disease caused by the recently discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a major global health crisis. Although no specific antiviral drugs have been proven to be fully effective against COVID-19, remdesivir (GS-5734), a nucleoside analogue prodrug, has shown beneficial effects when used to treat severe hospitalized COVID-19 cases. The molecular mechanism underlying this beneficial therapeutic effect is still vaguely understood. In this study, we assessed the effect of remdesivir treatment on the pattern of circulating miRNAs in the plasma of COVID-19 patients, which was analyzed using MiRCURY LNA miRNA miRNome qPCR Panels and confirmed by quantitative real-time RT-PCR (qRT-PCR). The results revealed that remdesivir treatment can restore the levels of miRNAs that are upregulated in COVID-19 patients to the range observed in healthy subjects. Bioinformatics analysis revealed that these miRNAs are involved in diverse biological processes, including the transforming growth factor beta (TGF-β), hippo, P53, mucin-type O-glycan biosynthesis, and glycosaminoglycan biosynthesis signaling pathways. On the other hand, three miRNAs (hsa-miR-7-5p, hsa-miR-10b-5p, and hsa-miR-130b-3p) were found to be upregulated in patients receiving remdesivir treatment and in patients who experienced natural remission. These upregulated miRNAs could serve as biomarkers of COVID-19 remission. This study highlights that the therapeutic potential of remdesivir involves alteration of certain miRNA-regulated biological processes. Targeting of these miRNAs should therefore be considered for future COVID-19 treatment strategies.

Abstract
CD4+CD25+ FOXP3+ regulatory T cells (Tregs) represent a subpopulation of CD4+ T cells central for the suppression of physiological and pathological immune reactions. Although distinct cell surface antigens are expressed in regulatory T cells, those components are also present on the surface of activated CD4+CD25- FOXP3-T cells, thus making the discrimination between Tregs and conventional CD4+ T difficult and isolation of Tregs complex. Yet, the molecular components driving Tregs' function are still not fully characterized. Aiming at unraveling molecular components specifically marking Tregs, and upon using quantitative real-time PCR (qRT-PCR) followed by bioinformatics analysis, we identified, in this study, differential transcriptional profiles, in peripheral blood CD4 + CD25 + CD127low FOXP3+ Tregs versus CD4 + CD25-FOXP3- conventional T cells, for set of genes with distinct immunological roles. In conclusion, this study identifies some novel genes that appeared to be differentially transcribed in CD4+ Tregs versus conventional T cells. The identified genes could serve as novel molecular targets relevant to Tregs' function and isolation.

Abstract
The skin is the outermost protective barrier of the human body. Its role is to protect against different physical, chemical, biological and environmental stressors. The vast majority of studies have focused on investigating the effects of single environmental stressors on skin homeostasis and the induction of several skin disorders, such as cancer or ageing. On the other hand, much fewer studies have explored the consequences of the co-exposure of skin cells to two or more stressors simultaneously, which is much more realistic. In the present study, we investigated, using mass-spectrometry-based proteomic analysis, the dysregulated biological functions in skin explants after their co-exposure to ultraviolet radiation (UV) and benzo[a]pyrene (BaP). We observed that several biological processes were dysregulated, among which autophagy appeared to be significantly downregulated. Furthermore, immunohistochemistry analysis was carried out to validate the downregulation of the autophagy process further. Altogether, the output of this study provides an insight into the biological responses of skin to combined exposure to UV + BaP and highlights autophagy as a potential target that might be considered in the future as a novel candidate for pharmacological intervention under such stress conditions.

Abstract
Cellular therapy aims to replace damaged resident cells by restoring cellular and molecular environments suitable for tissue repair and regeneration. Among several candidates, mesenchymal stem/stromal cells (MSCs) represent a critical component of stromal niches known to be involved in tissue homeostasis. In vitro, MSCs appear as fibroblast-like plastic adherent cells regardless of the tissue source. The therapeutic value of MSCs is being explored in several conditions, including immunological, inflammatory and degenerative diseases, as well as cancer. An improved understanding of their origin and function would facilitate their clinical use. The stemness of MSCs is still debated and requires further study. Several terms have been used to designate MSCs, although consensual nomenclature has yet to be determined. The presence of distinct markers may facilitate the identification and isolation of specific subpopulations of MSCs. Regarding their therapeutic properties, the mechanisms underlying their immune and trophic effects imply the secretion of various mediators rather than direct cellular contact. These mediators can be packaged in extracellular vesicles, thus paving the way to exploit therapeutic cell-free products derived from MSCs. Of importance, the function of MSCs and their secretome are significantly sensitive to their environment. Several features, such as culture conditions, delivery method, therapeutic dose and the immunobiology of MSCs, may influence their clinical outcomes. In this review, we will summarize recent findings related to MSC properties. We will also discuss the main preclinical and clinical challenges that may influence the therapeutic value of MSCs and discuss some optimization strategies.

Abstract
In recent decades, research on the therapeutic potential of progenitor cells has advanced considerably. Among progenitor cells, mesenchymal stromal cells (MSCs) have attracted significant interest and have proven to be a promising tool for regenerative medicine. MSCs are isolated from various anatomical sites, including bone marrow, adipose tissue, and umbilical cord. Advances in separation, culture, and expansion techniques for MSCs have enabled their large-scale therapeutic application. This progress accompanied by the rapid improvement of transplantation practices has enhanced the utilization of MSCs in regenerative medicine. During tissue healing, MSCs may exhibit several therapeutic functions to support the repair and regeneration of injured tissue. The process underlying these effects likely involves the migration and homing of MSCs, as well as their immunotropic functions. The direct differentiation of MSCs as a cell replacement therapeutic mechanism is discussed. The fate and behavior of MSCs are further regulated by their microenvironment, which may consequently influence their repair potential. A paracrine pathway based on the release of different messengers, including regulatory factors, chemokines, cytokines, growth factors, and nucleic acids that can be secreted or packaged into extracellular vesicles, is also implicated in the therapeutic properties of MSCs. In this review, we will discuss relevant outcomes regarding the properties and roles of MSCs during tissue repair and regeneration. We will critically examine the influence of the local microenvironment, especially immunological and inflammatory signals, as well as the mechanisms underlying these therapeutic effects. Importantly, we will describe the interactions of local progenitor and immune cells with MSCs and their modulation during tissue injury. We will also highlight the crucial role of paracrine pathways, including the role of extracellular vesicles, in this healing process. Moreover, we will discuss the therapeutic potential of MSCs and MSC-derived extracellular vesicles in the treatment of COVID-19 (coronavirus disease 2019) patients. Overall, this review will provide a better understanding of MSC-based therapies as a novel immunoregenerative strategy.

Abstract
Nowadays, the coronavirus disease (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents a major global health problem. Intensive efforts are being employed to better understand this pathology and develop strategies enabling its early diagnosis and efficient treatment. In this study, we compared the signature of circulating miRNAs in plasma of COVID-19 patients versus healthy donors. MiRCURY LNA miRNA miRNome qPCR Panels were performed for miRNA signature characterization. Individual quantitative real-time PCR (qRT-PCR) was carried out to validate miRNome qPCR results. Receiver-operator characteristic (ROC) curve analysis was applied to assess the diagnostic accuracy of the most significantly deregulated miRNA(s) as potential diagnostic biomarker(s). Eight miRNAs were identified to be differentially expressed with miR-17-5p and miR-142-5p being down-regulated whilst miR-15a-5p, miR-19a-3p, miR-19b-3p, miR-23a-3p, miR-92a-3p and miR-320a being up-regulated in SARS-CoV-2-infected patients. ROC curve analyses revealed an AUC (Areas Under the ROC Curve) of 0.815 (P = 0.031), 0.875 (P = 0.012), and 0.850 (P = 0.025) for miR-19a-3p, miR-19b-3p, and miR-92a-3p, respectively. Combined ROC analyses using these 3 miRNAs showed a greater AUC of 0.917 (P = 0.0001) indicating a robust diagnostic value of these 3 miRNAs. These results suggest that plasma miR-19a-3p, miR-19b-3p, and miR-92a-3p expression levels could serve as potential diagnostic biomarker and/or a putative therapeutic target during SARS-CoV-2-infection.

Abstract
Small bone defects can heal spontaneously through the bone modeling process due to their physiological environmental conditions. The bone modeling cycle preserves the reliability of the skeleton through the well-adjusted activities of its fundamental cell. Stem cells are a source of pluripotent cells with a capacity to differentiate into any tissue in the existence of a suitable medium. The concept of bone engineering is based on stem cells that can differentiate into bone cells. Mesenchymal stromal cells have been evaluated in bone tissue engineering due to their capacity to differentiate in osteoblasts. They can be isolated from bone marrow and from several adults oral and dental tissues such as permanent or deciduous teeth dental pulp, periodontal ligament, apical dental papilla, dental follicle precursor cells usually isolated from the follicle surrounding the third molar, gingival tissue, periosteum-derived cells, dental alveolar socket, and maxillary sinus Schneiderian membrane-derived cells. Therefore, a suitable animal model is a crucial step, as preclinical trials, to study the outcomes of mesenchymal cells on the healing of bone defects. We will discuss, through this paper, the use of mesenchymal stem cells obtained from several oral tissues mixed with different types of scaffolds tested in different animal models for bone tissue engineering. We will explore and link the comparisons between human and animal models and emphasized the factors that we need to take into consideration when choosing animals. The pig is considered as the animal of choice when testing large size and multiple defects for bone tissue engineering.

Abstract
Mesenchymal stem cells, being characterized by high self-renewal capacity and multi-lineage differentiation potential, are widely used in regenerative medicine especially for repair of bone defects in patients with poor bone regenerative capacity. In this study, we aimed to compare the osteogenic potential of human maxillary schneiderian sinus membrane (hMSSM)-derived stem cells versus permanent teeth dental pulp stem cells (DPSCs). Both cells types were cultivated in osteogenic and non-osteogenic inductive media. Alkaline phosphatase (ALP) activity assay and quantitative real-time PCR analysis were carried out to assess osteogenic differentiation. We showed that ALP activity and osteoblastic markers transcription levels were more striking in hMSSM-derived stem cells than DPSCs. Our results highlight hMSSM-derived stem cells as a recommended stem cell type for usage during bone tissue regenerative therapy.

Abstract
Xeroderma Pigmentosum C (XPC) is a multi-functional protein that is involved not only in the repair of bulky lesions, post-irradiation, via nucleotide excision repair (NER) per se but also in oxidative DNA damage mending. Since base excision repair (BER) is the primary regulator of oxidative DNA damage, we characterized, post-Ultraviolet B-rays (UVB)-irradiation, the detailed effect of three different XPC mutations in primary fibroblasts derived from XP-C patients on mRNA, protein expression and activity of different BER factors. We found that XP-C fibroblasts are characterized by downregulated expression of different BER factors including OGG1, MYH, APE1, LIG3, XRCC1, and Polβ. Such a downregulation was also observed at OGG1, MYH, and APE1 protein levels. This was accompanied with an increase in DNA oxidative lesions, as evidenced by 8-oxoguanine levels, immediately post-UVB-irradiation. Unlike in normal control cells, these oxidative lesions persisted over time in XP-C cells having lower excision repair capacities. Taken together, our results indicated that an impaired BER pathway in XP-C fibroblasts leads to longer persistence and delayed repair of oxidative DNA damage. This might explain the diverse clinical phenotypes in XP-C patients suffering from cancer in both photo-protected and photo-exposed areas. Therapeutic strategies based on reinforcement of BER pathway might therefore represent an innovative path for limiting the drawbacks of NER-based diseases, as in XP-C case.

Abstract
MicroRNAs, short non-coding single-stranded RNAs, are important regulators and gatekeepers of the coding genes in the human genome. MicroRNAs are highly conserved among species and expressed in different tissues and cell types. They are involved in almost all the biological processes as apoptosis, proliferation, cell cycle arrest and differentiation. Playing all these roles, it is not surprising that the deregulation of the microRNA profile causes a number of diseases including cancer. Breast cancer, the most commonly diagnosed malignancy in women, accounts for the highest cancer-related deaths worldwide. Different microRNAs were shown to be up or down regulated in breast cancer. MicroRNAs can function as oncogenes or tumor suppressors according to their targets. In this review, the most common microRNAs implicated in breast cancer are fully illustrated with their targets. Besides, the review highlights the effect of exosomal microRNA on breast cancer and the effect of microRNAs on drug and therapies resistance as well as the miRNA-based therapeutic strategies used until today.

Abstract
OBJECTIVE Dental pulp stem cells (DPSCs) and stem cells from human exfoliated deciduous teeth (SHED) are types of human dental tissue-derived mesenchymal stem cells (MSCs) that have emerged as an interesting and promising source of stem cells in the field of tissue engineering. The aim of this work is to isolate stem cells from DPSCs and SHED, cultivate them in vitro and compare their odontogenic differentiation potential. METHODS DPSCs and SHED were extracted from molars, premolars and canines of six healthy subjects aged 5-29 years. The cells were characterized, using flow cytometry, for mesenchymal stem cell surface markers. MTT colorimetric assay was applied to assess cell viability. Alizarin red staining, alkaline phosphatase (ALP) activity, quantitative real-time PCR (qRT-PCR) and western blot were carried out to determine DPSCs and SHED osteogenic/odontogenic differentiation. RESULTS DPSCs express higher STRO-1 and CD44 levels compared to SHED. Moreover, the cells differentiate and acquire columnar shape with a level of calcium deposition and mineralization that is the same between DPSCs and SHED. ALP activity, ALP, COLI, DMP-1, DSPP, OC, and RUNX2 (osteogenic/odontogenic differentiation markers) expression levels were higher in DPSCs. CONCLUSIONS DPSCs and SHED express MSCs markers. Although both cell types had calcium deposits, DPSCs presented a higher ALP activity level. In addition, DPSCs showed higher levels of osteogenic and odontogenic differentiation markers such as COLI, DSPP, OC, RUNX2, and DMP-1. These results suggest that DPSCs are closer to the phenotype of odontoblasts than SHED and may improve the efficacy of human dental tissue-derived mesenchymal stem cells therapeutic protocols. 'CLINICAL SIGNIFICANCE' DPSCs are closer than t SHED to the phenotype of odontoblasts. This would be helpful to enable better therapeutic decisions when applying MSCs-based therapy in the field of dentistry.

Abstract
The development and progression of different pathologies including, cancer, are associated with suppressed immune responses. This restrained immune activity could be associated with the activation of different immune checkpoint pathways that mediate immunosuppressive functions. Therapeutic Protocols based on abolishing the activity of immune check points provided a promising potential for treating cancer. Among the distinct known immune checkpoints, PD-1/PD-L1 and CTLA-4, are the most studied and have been the focus for development of different blocking agents. Monoclonal antibodies that can block PD-1, PD-L1 or CTLA4 have been approved for treatment of different cancers. MicroRNAs (miRNAs), short non-coding regulatory RNA molecules, could repress mRNA expression at a post-transcriptional level. Many miRNAs have been reported to modulate the expression of CTLA-4 and PD-1/PD-L1, either directly or indirectly, in multiple pathological cases, mainly cancer. In this review, after a brief introduction about T cell activation and immune checkpoints, the miRNAs regulating the expression of CTLA-4 and PD-1/PD-L1 are discussed with highlights on their role in cancer. Many of these miRNAs could serve as novel treatments in different types of cancer as detailed throughout the review.

Abstract
Regenerative endodontics is a biologically based treatment designed for immature permanent teeth with necrotic pulp to replace dentin and root structures, as well as dental pulp cells. This procedure has become a part of novel modality in endodontics therapeutic manner, and it is considered as an alternative to apexification. In the last decade, numerous case reports, which describe this procedure, have been published. This therapeutic approach succeeded due to its lower financial cost and ease of performance. Although the clinical protocol of this procedure is not standardized and the effects of irrigants and medicaments on dental stem cells fate remain somewhat ambiguous, however when successful, it is an improvement of endodontics treatment protocols which leads to continued root development, increased dentinal wall thickness, and apical closure of immature teeth. To ensure a successful regenerative procedure, it is essential to investigate the appropriate disinfection protocols and the use of biocompatible molecules in order to control the release of growth factors and the differentiation of stem cells. This is the first review in the literature to summarize the present knowledge regarding the effect of intracanal irrigants and medicaments on the dental derived stem cells fate in regenerative endodontic procedures.

Abstract
The broad clinical applications of Mesenchymal Stem Cells (MSCs) in the regenerative medicine field is attributed to their ability to self-renew and differentiate into multiple cellular lineages. Nowadays, MSCs can be derived from a variety of adult and fetal tissues including bone marrow, adipose tissue, umbilical cord and placenta. The difficulties associated with the isolation of MSCs from certain tissues such as bone marrow promoted the search for alternative tissues which are easily accessible. Oral derived MSCs include dental pulp stem cells (DPSCs), dental follicle progenitor cells (DFPC), and periodontal ligament stem cells (PDLSC). Being abundant and easily accessible, oral derived MSCs represent an interesting alternative MSC type to be employed in regenerative medicine. Human periapical cyst-mesenchymal stem cells (hPCy-MSCs) correspond to a newly discovered and characterized MSC subtype. Interestingly, hPCy-MSCs are collected from periapical cysts, which are a biological waste, without any influence on the other healthy tissues in oral cavity. hPCy-MSCs exhibit cell surface marker profile similar to that of other oral derived MSCs, show high proliferative potency, and possess the potential to differentiate into different cell types such as osteoblasts, adipocytes and neurons-like cells. hPCy-MSCs, therefore, represent a novel promising MSCs type to be applied in regenerative medicine domain. In this review, we will compare the different types of dental derived MSCs, we will highlight the isolation technique, the characteristics, and the therapeutic potential of hPCy-MSCs.

Abstract
Interleukin-21 (IL-21) is a cytokine with potent regulatory effects on different immune cells. Recently, IL-21 has been contemplated for use in the treatment of cancers. However, the molecular mechanisms regulating human IL-21 gene expression has not yet been described. In this study, we initially studied the promoter region and identified the transcription start site. We thereafter described the essential region upstream of the transcription start site and showed the in vivo binding of NFATc2 and SP1 transcription factors to this region, in addition to their positive role in IL-21 expression. We also studied the role of microRNAs (miRNAs) in regulating IL-21 expression. We, thus, established the miRNA profile of CD4+CD45RO+ versus CD4+CD45RA+ isolated from healthy volunteers and identified a signature composed of 12 differentially expressed miRNAs. We showed that miR-302c is able to negatively regulate IL-21 expression by binding directly to its target site in the 3'-untranslated region. Moreover, after using fresh human CD4-positive T cells, we observed the high acetylation level of histone H4, an observation well in line with the already described high expression of IL-21 in CD4+CD45RO+ versus CD4+CD45RA+ T cells. Altogether, our data identified different molecular mechanisms regulating IL-21 expression.

Abstract
Mesenchymal stromal cells (MSCs), characterized by both multidifferentiation potential and potent immunomodulatory capacity, represent a promising, safe and powerful cell based-therapy for repairing tissue damage and/or treating diseases associated with aberrant immune responses. Natural killer (NK) cells are granular lymphocytes of the innate immune system that function alone or in combination with other immune cells to combat both tumors and virally infected cells. After their infusion, MSCs are guided by host inflammatory elements and can interact with different immune cells, particularly those of the innate immune system. Although some breakthroughs have been achieved in understanding these interactions, much remains to be determined. In this review, we discuss the complex interactions between NK cells and MSCs, particularly the importance of improving the therapeutic value of MSCs.

Abstract
Background:
Propolis is a resinous substance produced by bees and known to possess antioxidant,
antimicrobial, antiproliferative and anti-inflammatory activities.
Objective:
This study is aimed at evaluating the in vivo and in vitro anti-inflammatory potential of the
Crude Ethanolic Extract (CE) of Lebanese propolis and its Ethyl Acetate Fraction (EAF).
Method:
Chemical content of propolis was characterized using high-performance liquid chromatography
and LC-MS/MS. COX-2 and iNOS protein expression, nitric oxide (NO) and prostaglandin
(PGE2) release in LPS-activated RAW monocytes were achieved respectively by western blot and
spectrophotometry. Antioxidant activity was evaluated by DPPH free radical scavenging assay. Measurement
of paw thickness in carrageenan-induced paw edema in mice and pathologic assessment of inflammation
in paw sections were used to judge the anti-inflammatory properties of propolis.
Results:
Pathology analysis revealed in the treated group significant reduction of immune cell infiltration
and edema. Both extract and ethyl acetate fraction showed significant anti-inflammatory and antioxidant
effects in LPS-treated RAW cells characterized by the inhibition of COX-2 and iNOS protein
expression, as well as PGE2 and NO release. Chemical analysis of the crude extract and its ethyl acetate
fraction identified 28 different compounds of which two phenolic acids and nine other flavonoids
were also quantified. Ferulic acid, caffeic acid, chrysin, galangin, quercetin, and pinocembrin were
among the most representative compounds.
Conclusion:
Lebanese propolis is rich in a various amount of flavonoids which showed promising antiinflammatory
and antioxidant properties. Additionally, chemical analysis showed unique chemical
compositions with the potential of identifying ingredients with interesting anti-inflammatory activities.

Abstract
Background Due to their chemical constituents and biological properties, plants have long been used to control life-threatening diseases. The flora of Lebanon includes many plants that have already been demonstrated to have medicinal value, and other species, such as Pentapera sicula libanotica, that are yet to be characterized. The present study characterized the chemical composition, anti-oxidant, anti-inflammatory, and anti-proliferative potential of aqueous, ethanol, and methanol extracts derived from the leaves of the Lebanese Pentapera plant. Material/Methods High-performance liquid chromatography (HPLC) was used to determine the chemical composition. Gas chromatography (GC) coupled with mass spectrometry (MS) was applied to determine the content of essential oil. DPPH radical scavenging assay was performed to evaluate the anti-oxidant potential. The anti-inflammatory potential was assessed using quantitative real-time PCR (qRT-PCR) by measuring TNF-α, IL-6, and CCL4 mRNA levels, and we assessed Cox-2 and iNOS proteins levels using Western blot (WB) analysis. MTT assay was carried out to determine the anti-proliferative potential. Results We identified, mainly in the alcoholic (methanol and ethanol) extracts, distinct bioactive compounds with pharmacological relevance. In parallel, with their phytochemical content, these 2 extracts showed significant anti-oxidant, anti-inflammatory and anti-proliferative capacities. Conclusion Pentapera sicula libanotica appears to be a promising pharmacological tool.

Abstract
BACKGROUND Novel treatments for bone defects, particularly in patients with poor regenerative capacity, are based on bone tissue engineering strategies which include mesenchymal stem cells (MSCs), bioactive factors, and convenient scaffold supports. OBJECTIVE In this study, we aimed at comparing the potential for different scaffolds to induce osteogenic differentiation of human maxillary Schneiderian sinus membrane- (hMSSM-) derived cells. Methods. hMSSM-derived cells were seeded on gelatin, collagen, or Hydroxyapatite β-Tricalcium phosphate-Fibrin (Haβ-TCP-Fibrin) scaffolds. Cell viability was determined using an MTT assay. Alizarin red staining method, Alkaline phosphatase (ALP) activity assay, and quantitative real-time PCR analysis were performed to assess hMSSM-derived cells osteogenic differentiation. RESULTS Cell viability, calcium deposition, ALP activity, and osteoblastic markers transcription levels were most striking in gelatin scaffold-embedded hMSSM-derived cells. CONCLUSION Our findings suggest a promising potential for gelatin-hMSSM-derived cell construct for treating bone defects.

Abstract
Due to their immune-therapeutic value, adipose tissue-derived mesenchymal stromal cells (AT-MSCs) require a better characterization of their interplay with natural killer (NK) cells known to contribute to the graft-versus-leukemia effects. When cultivated together, AT-MSCs showed cellular cytotoxicity and were therefore killed by NK cells in an activating-cytokine dependent manner. In the presence of AT-MSCs, both ligands and receptors known to drive NK cell interactions were significantly altered. During this co-culture, the proliferation of NK cells was slightly reduced, while their IFN-γ and TNF-α secretion was significantly increased. NK cells displayed sustained degranulation accompanied by increased discharge of their cytolytic granules (perforin, granzymes A and B). On the other hand, activated NK cells reduced the expression of serpins C1 and B9 in AT-MSCs. Collectively, reciprocal immuno-biological alterations occur during the co-culture of NK cells and AT-MSCs. Understanding these changes will increase the safety and efficacy of cell-based immuno-oncotherapy.

Abstract
BACKGROUND AND AIMS Endothelial cells are main actors in vascular homeostasis as they regulate vascular pressure and permeability as well as hemostasis and inflammation. Disturbed stimuli delivered to and by endothelial cells correlate with the so-called endothelial dysfunction and disrupt this homeostasis. As constituents of the inner layer of blood vessels, endothelial cells are also involved in angiogenesis. Apolipoprotein Ls (APOL) comprise a family of newly discovered apolipoproteins with yet poorly understood function, and are suggested to be involved in inflammatory processes and cell death mechanisms. Here we investigate the role of APOLs in endothelial cells stimulated with factors known to be involved in atherogenesis and their possible contribution to endothelial dysfunction with an emphasis on inflammation driven-angiogenesis in vitro. METHODS Using the CRISPR/Cas9 technique, we analyzed the effect of APOL3 gene knock out in HMEC-1 endothelial cells on cell migration, tubulogenesis, endothelial permeability, intracellular signal transduction as assessed by kinase phosphorylation, and angiogenesis gene expression (measured by qRT-PCR). RESULTS Our results indicate that among the family, APOL3 was the only member induced by myeloperoxidase, oxidized LDL, VEGF and FGF treatments. APOL3 invalidation increased endothelial permeability, reduced wound repair and tubule formation in vitro, the latter only in MPO and VEGF-induced conditions. Accordingly, some pro-angiogenic signaling pathways (ERK1/2 and FAK but not Akt) and some pro-angiogenic genes were partially inhibited in APOL3 knock out cells. CONCLUSIONS These findings suggest the involvement of APOL3 in angiogenesis in vitro and as a modulator of MAPK and FAK signaling in endothelial cells.

Abstract
OBJECTIVES We aimed at characterizing the transcription profiles of immunological receptors associated with the biology of mesenchymal stromal cells (MSCs). MATERIALS AND METHODS In this experimental study, quantitative real time-polymerase chain reaction (qRTPCR) was performed to establish the transcription profiles of advanced glycation end-products (RAGE) receptor, C-type lectin receptors (CLRs, including DECTIN-1, DECTIN-2 and MINCLE), leukotriene B4 (LTB4) receptors (BLT1 and BLT2) and cysteinyl leukotrienes (CysLTs) receptors (CYSLTR1 and CYSLTR2) in distinct populations of MSCs grown under basic or inflammatory conditions. RESULTS MSCs derived from adipose tissue (AT), foreskin (FSK), Wharton's jelly (WJ) and bone marrow (BM) exhibited significantly different transcription levels for these genes. Interestingly, these transcription profiles substantially changed following exposure of MSCs to inflammatory signals. CONCLUSIONS Collectively, for the first time, our data highlights that MSCs depending on their tissue-source, present several relevant receptors potentially involved in the regulation of inflammatory and immunological responses. Understanding the roles of these receptors within MSCs immunobiology will incontestably improve the efficiency of utilization of MSCs during cell-based therapies.

Abstract
Due to their easier isolation, multilineage potential, and immunomodulatory capacity, Wharton's Jelly-derived mesenchymal stromal cells (WJ-MSCs) exhibit promising efficacy in the field of regenerative medicine and immunotherapy. Characterization of WJ-MSCs-natural killer (NK) cells crosstalk is required for ameliorating the medicinal value of WJ-MSCs. Here, we revealed that the outcome of WJ-MSCs-NK cells crosstalk varied according to the type of cytokines (IL-2, IL-12, IL-15 and IL-21) utilized to activate NK cells. Differently activated NK cells exerted distinct cytotoxicities against WJ-MSCs causing their probable death. Cell surface ligands (CD112, CD155, ULPB-3) and receptors (LAIR, CD226, CD314, CD335, CD336 and CD337) governing the interaction between NK cells and their targets, exhibited altered expression profiles following the co-culture with WJ-MSCs. Although partly inhibited NK cell proliferation, WJ-MSCs enhanced activated NK-cell-mediated secretion of IFN-γ and TNF-α. Moreover, WJ-MSCs reinforced NK cells' degranulation as well as secretion of perforin and granzymes. On the other hand, WJ-MSCs displayed only slight increase in ROS generation but significant decrease in A1 and C1 serpins expression following co-culture with activated NK cells. Altogether, our results highlight that WJ-MSCs-NK cells interaction may affect both cell type features and, therefore, their therapeutic properties.

Abstract
Foreskin-mesenchymal stromal cells (FSK-MSCs) are immune-privileged thus making them valuable immunotherapeutic cell product. Characterization of the relationship between FSK-MSCs and natural killer (NK) cells is essential to improve cell-based therapy. In the present study, we studied for the first time FSK-MSCs-NK interaction and showed that the result of such cross talk was robustly dependent on the type of cytokines (IL-2, IL-12, IL-15, and IL-21) employed to activate NK cells. Distinctly activated-NK cells showed uneven cytotoxicity against FSK-MSCs, triggering their death in fine. The expression of different cell-surface ligands (CD112, CD155, ULPB-3) and receptors (LAIR, KIRs) ensuring such interaction was altered following co-culture of both populations. Despite their partial negative effect on NK cell proliferation, FSK-MSCs boosted the capacity of activated NK-cells to secrete IFN-γ and TNF-α. Moreover, FSK-MSCs enhanced degranulation of NK cells, reinforced secretion of perforin and granzymes, while only modestly increased ROS production. On the other hand, FSK-MSCs-mediated expression of C1 and B9 serpins was significantly lowered in the presence of activated NK cells. Altogether, our results highlight major immunological changes following FSK-MSCs-NK interaction. Understanding these outcomes will therefore enhance the value of the therapeutic strategy.

Abstract
Bone marrow-derived mesenchymal stromal cells (BM-MSCs) are multipotent progenitor cells that have shown promise for several different therapeutic applications. As they are able to modulate the function of several types of immune cells, BM-MSCs are highly important in the field of cell-based immunotherapy. Understanding BM-MSC-natural killer (NK) cell interactions is crucial for improving their therapeutic efficiency. Here, we observed that the type of NK cell-activating cytokine (e.g., IL-2, IL-12, IL-15 and IL-21) strongly influenced the outcomes of their interactions with BM-MSCs. The expression patterns of the ligands (CD112, CD155, ULPB-3) and receptors (LAIR, NCR) mediating the cross-talk between BM-MSCs and NK cells were critically modulated following co-culture. BM-MSCs partially impaired NK cell proliferation but up-regulated their secretion of IFN-γ and TNF-α. As they are cytotoxic, activated NK cells induced the killing of BM-MSCs. Indeed, BM-MSCs triggered the degranulation of NK cells and increased their release of perforin and granzymes. Interestingly, activated NK cells induced ROS generation within BM-MSCs that caused their decreased viability and reduced expression of serpin B9. Collectively, our observations reveal that BM-MSC-NK cell interactions may impact the immunobiology of both cell types. The therapeutic potential of BM-MSCs will be significantly improved once these issues are well characterized.

Abstract
Medial artery calcification, a hallmark of type 2 diabetes mellitus and chronic kidney disease (CKD), is known as an independent risk factor for cardiovascular mortality and morbidity. Hyperphosphatemia associated with CKD is a strong stimulator of vascular calcification but the molecular mechanisms regulating this process remain not fully understood. We showed that calcification was induced after exposing Sprague-Dawley rat aortic explants to high inorganic phosphate level (Pi , 6 mM) as examined by Alizarin red and Von Kossa staining. This calcification was associated with high Tissue-Nonspecific Alkaline Phosphatase (TNAP) activity, vascular smooth muscle cells de-differentiation, manifested by downregulation of smooth muscle 22 alpha (SM22α) protein expression which was assessed by immunoblot analysis, immunofluorescence, and trans-differentiation into osteo-chondrocyte-like cells revealed by upregulation of Runt related transcription factor 2 (Runx2), TNAP, osteocalcin, and osteopontin mRNA levels which were determined by quantitative real-time PCR. To unravel the possible mechanism(s) involved in this process, microRNA (miR) expression profile, which was assessed using TLDA technique and thereafter confirmed by individual qRT-PCR, revealed differential expression 10 miRs, five at day 3 and 5 at day 6 post Pi treatment versus control untreated aortas. At day 3, miR-200c, -155, 322 were upregulated and miR-708 and 331 were downregulated. After 6 days of treatment, miR-328, -546, -301a were upregulated while miR-409 and miR-542 were downregulated. Our results indicate that high Pi levels trigger aortic calcification and modulation of certain miRs. These observations suggest that mechanisms regulating aortic calcification might involve miRs, which warrant further investigations in future studies.

Abstract
Mesenchymal stromal cells (MSCs) display a special immunological profile that allows their potential use as immunotherapeutic cells. Nowadays, foreskin (FSK) represents a valuable reservoir of MSCs with International Society for Cellular Therapy (ISCT) compliant criteria and relevant functional properties. However, their mode of action is poorly understood and needs to be more elucidated to optimize their therapeutic use. Because microRNAs (miRNAs) act as key regulators in a wide variety of biological processes, we decided to establish the micronome of FSK-MSCs, the influence of inflammation and the predicted target pathways. Here, we provide the full list of unchanged and additional four differentially expressed miRNAs, miR-199b, -296-3p and -589-5p being downregulated whilst miR-146-3p being upregulated, in MSCs following their exposure to a cocktail of proinflammatory cytokines. MicroRNA target prediction in addition to Pathway enrichment analysis performed using miRNet, showed that miR-296-3p is linked to antigen processing and presentation pathway. Collectively, our data indicate that the micronome of FSK-MSCs is partially responsive to inflammation. Differentially expressed miRNAs are subsequently modulated by inflammation and seem to be involved in regulating the immunological fate of FSK-MSCs. These miRNAs deserve more attention in order to optimize MSC-based therapy and achieve the appropriate therapeutic effect.

Abstract
Background This study aimed to identify the phytochemical content and evaluate the antioxidant, anti-inflammatory, and antiproliferative capacities of various solvent extracts of Ephedra campylopoda stems. Material/Methods Fresh stems were suspended in 3 different solvent systems, including distilled water, ethanol, and methanol. The chemical composition was determined using high-performance liquid chromatography (HPLC), and the content of essential oil of this plant species was determined by gas chromatography (GC) coupled with mass spectrometry (MS). Antioxidant activity was determined using DPPH radical scavenging and Fe2+-chelating activity assays. Anti-inflammatory capacity was estimated by both evaluating RAW 264.7 murine macrophage cells-mediated secretion of PGE2 using ELISA technique, and quantifying the mRNA level of the pro-inflammatory cytokines (IL-α, IL-β and IL-6), chemokines (CCL3 and CCL4), and inflammation-inducible COX-2 and iNOS enzymes using quantitative real-time PCR (qRT-PCR). The antiproliferative potential was determined using the XTT viability assay. Results Our results showed that the alcoholic extracts were better than the aqueous one in terms of their chemical composition. In parallel, the alcoholic extracts showed more potent antioxidant, anti-inflammatory, and antiproliferative capacities than aqueous extract. Conclusions Our observations suggest that Ephedra campylopoda plant could be a promising resource of natural products with antioxidant, anti-inflammatory and antiproliferative capacities.

Abstract
Background In the present study, phytochemical screening, antioxidant, anti-inflammatory, and antiproliferative capacities of 3 extracts from leaves of Lebanese Crataegus azarolus L. were evaluated. Material/Methods Fresh leaves were dissolved in 3 different solvents: distilled water, ethanol, and methanol. The chemical composition was determined using high-performance liquid chromatography (HPLC) and the content of essential oil of this plant was examined by gas chromatography (GC) coupled with mass spectrometry (MS). The antioxidant potential was evaluated using DPPH radical scavenging and Fe2+ chelating activity assays. Anti-inflammatory effect was investigated by measuring the secreted amounts of the proinflammatory mediator PGE2 using ELISA technique, as well as by assaying the mRNA levels of the proinflammatory cytokines (IL-α, IL-β, and Il-6), chemokines (CCL3 and CCL4) and inflammation-sensitive COX2 and iNOS enzymes using quantitative real-time PCR (qRT-PCR). The antiproliferative effect was evaluated using the XTT viability assay. Results The obtained results show that alcohol (methanol and ethanol) extracts were rich in bioactive molecules with medical relevance and exerted substantial antioxidant, anti-inflammatory, and antiproliferative capacities. On the other hand, aqueous extract contained fewer chemical components and exhibited less therapeutic efficiency. Conclusions Our observations indicate that Crataegus azarolus L. could be used for treating diseases related to oxidative stress, inflammatory reactions, and uncontrolled cell growth.

Abstract
Background Mesenchymal stromal cells (MSCs) possess potent immunomodulatory properties that increase their value as a cell-based therapeutic tool for managing various immune-based disorders. Over the past years, accumulated results from trials using MSCs-based therapy have shown substantial contradictions. Although the reasons underlying these discrepancies are still not completely understood, it is well known that the immunomodulatory activities mediated by distinct MSCs differ in a manner dependent on their tissue origin and adequate response to inflammation priming. Thus, characterization of new molecular pathway(s) through which distinct MSC populations can exert their immunomodulatory effects, particularly during inflammation, will undoubtedly enhance their therapeutic potential. Material/Methods After confirming their compliance with ISCT criteria, quantitative real time-PCR (qRT-PCR) was used to screen new immunoregulatory genes in MSCs, derived from adipose tissue, foreskin, Wharton’s jelly or the bone-marrow, after being cultivated under normal and inflammatory conditions. Results FGL2, GAL, SEMA4D, SEMA7A, and IDO1 genes appeared to be differentially transcribed in the different MSC populations. Moreover, these genes were not similarly modulated following MSCs-exposure to inflammatory signals. Conclusions Our observations suggest that these identified immunoregulatory genes may be considered as potential candidates to be targeted in order to enhance the immunomodulatory properties of MSCs towards more efficient clinical use.

Abstract
In this Data in Brief, we have provided data describing the secretion profile of two main immunoregulatory proteins, heme oxygenase-1 (HO-1) and CD200, from bone marrow (BM), Wharton׳s Jelly (WJ) or adipose tissue (AT) mesenchymal stromal cells (MSCs) being cultivated either in the absence or presence of activated T-cells. Whilst HO-1 is a stress-responsive enzyme displaying diverse cytoprotective effects, CD200 is a membrane glycoprotein delivering immunoregulatory signals following interaction with its receptor (CD200R). Using Enzyme-linked immunosorbent assay (ELISA) techniques, these data are presented to show distinct constitutive secretion of both HO-1 and CD200 depending on MSC types. The data presented also demonstrate that the protein levels of HO-1 and CD200 are differentially modulated during co-culture with activated T-cells. All assays were carried out in triplicates and the mean values are reported. The data presented in this article are complementary to our previously published report entitled “The Immunomodulatory Potential of Mesenchymal Stromal Cells: A Story of a Regulatory Network.” [1].

Abstract
Background Due to their self-renewal capacity, multi-lineage potential, and immunomodulatory properties, mesenchymal stromal cells (MSCs) are an attractive tool for different therapeutic strategies. Foreskin (FSK), considered as a biological waste material, has already been shown to be a valuable source of MSCs. Besides their typical fibroblast like morphology and International Society for cellular Therapy compliant phenotype, foreskin-MSCs (FSK–MSCs) are clonogenic, and highly proliferative cells with multi-lineage and strong immunomodulatory capacities. Of importance, FSK–MSCs properly adjust their fate following exposure to inflammatory signals. Being potent regulators of gene expression, miRNAs are involved in modulating nearly all cellular processes and in orchestrating the roles of different immune cells. In this study, we characterized the miRNome of FSK–MSCs by determining the expression profile of 380 different miRNAs in inflammation primed vs. control non-primed cells. Methods TaqMan low density array (TLDA) was performed to identify dysregulated miRNAs after exposing FSK–MSCs to inflammatory signals. Quantitative real-time RT-PCR was carried out to validate the observations. DIANA-miRPath analysis web server was used to identify potential pathways that could be targeted by the dysregulated miRNAs. Results Sixteen miRNAs were differentially expressed in inflammation-primed vs. non-primed FSK–MSCs. The expression level of miR-27a, -145, -149, -194, -199a, -221, -328, -345, -423-5p, -485-3p, -485-5p, -615-5p and -758 was downregulated whilst that of miR-155, -363 and -886-3p was upregulated. Target pathway prediction of those differentially expressed miRNAs identified different inflammation linked pathways. Conclusions After determining their miRNome, we identified a striking effect of inflammatory signals on the miRNAs’ expression levels in FSK–MSCs. Our results highlight a potential role of miRNAs in modulating the transcription programs of FSK–MSCs in response to inflammatory signals. Further, we propose that specific miRNAs could serve as interesting targets to manipulate some functions of FSK–MSCs, thus ameliorating their therapeutic potential.

Abstract
AIMS AND OBJECTIVES The aim of this study was to assess the correlation between the remaining dentin thickness (RDT) in deep decayed primary molars and the inflammatory status and bacterial composition of the corresponding coronal pulp. We hypothesized that RDT could be used as a reference for clinicians in assigning the indication for pulpotomy. MATERIALS AND METHODS Pulpotomies were conducted on the cameral pulp of 48 primary molars. Microorganisms, such as Lactobacillus sp., Streptococcus sp., and Prevotella sp., were identified and quantified and levels of tumor necrosis factor-alpha (TNF-α) and interlukin-6 (IL-6) were assessed. The correlation between the pre-operative RDT based on radiographic images and inflammatory-microbial profiles in vitro was evaluated using Spearman's rho correlation coefficient. All data analysis was performed using a statistical software program (SPSS 20.0, SPSS Inc., Chicago, IL, USA). RESULTS Immunological and microbiological studies revealed elevated levels of TNF-α and IL-6 cytokines, and Lactobacillus sp., Streptococcus sp. and Prevotella sp. in the cameral pulp with an RDT measuring up to 1.1 mm. No significant relationship could be established between RDT, inflammatory status and microbial content of the pulps. CONCLUSION The RDT remains a key clinical factor that needs to be assessed when establishing the indication for pulpotomy. Additional parameters that can improve this therapy should be investigated in the future.

Abstract
The chemokine C receptor 7 (CCR7) is a G-protein-coupled heptahelical receptor (GPCR) that is expressed on a wide variety of cells including memory T cells, B cells, mature dendritic cells, and cancer cells. Activated by its ligands CCL19 or CCL21, CCR7 plays a major role in metastasis of cancer cells. Recent studies demonstrated the role of NF-κB and AP-1 transcription factors in addition to let-7 microRNA in CCR7 expression. Our ChIP assays further show the binding of Sp-1, Sp-3 and NFAT-1 transcription factors to their potential binding sites in the 1Kb promoter region with the later found to inhibit whilst Sp-1, and Sp-3 were found to stimulate CCR7 expression as demonstrated by transfection assays. On the other hand, in addition to the known let-7 regulation of CCR7, we found miR-21 to have a highly conserved target region in CCR7 3'UTR and to be significantly down-regulated during the course of dendritic cell maturation, allowing for high expression of CCR7.

Abstract
BACKGROUND MicroRNAs (miRNAs) are small (19-22-nt) single-stranded noncoding RNA molecules whose deregulation of expression can contribute to human disease including the multistep processes of carcinogenesis in human. Circulating miRNAs are emerging biomarkers in many diseases and cancers such as type 2 diabetes, pulmonary disease, colorectal cancer, and gastric cancer among others; however, defining a plasma miRNA signature in acute myeloblastic leukemia (AML) that could serve as a biomarker for diagnosis or in the follow-up has not been done yet. METHODS TaqMan miRNA microarray was performed to identify deregulated miRNAs in the plasma of AML patients. Quantitative real-time RT-PCR was used to validate the results. Receiver-operator characteristic (ROC) curve analysis was conducted to evaluate the diagnostic accuracy of the highly and significantly identified deregulated miRNA(s) as potential candidate biomarker(s). RESULTS The plasma expression level of let-7d, miR-150, miR-339, and miR-342 was down-regulated whilst that of let-7b, and miR-523 was up-regulated in the AML group at diagnosis compared to healthy controls. ROC curve analyses revealed an AUC (the areas under the ROC curve) of 0.835 (95% CI: 0.7119- 0.9581; P<0.0001) and 0.8125 (95% CI: 0.6796-0.9454; P=0.0005) for miR-150, and miR-342 respectively. Combined ROC analyses using these 2 miRNAs revealed an elevated AUC of 0.86 (95% CI: 0.7819-0.94; P<0.0001) indicating the additive effect in the diagnostic value of these 2 miRNAs. QRT-PCR results showed that the expression level of these two miRs in complete remission AML patients resembled that of healthy controls. CONCLUSIONS Our findings indicated that plasma miR-150 and miR-342 are novel important promising biomarkers in the diagnosis of AML. These novel and promising markers warrant validation in larger prospective studies.

Abstract
Regulatory T cells (Tregs) are characterized by a high expression of IL-2 receptor α chain (CD25) and of forkhead box P3 (FOXP3), the latter being essential for their development and function. Another major player in the regulatory function is the cytotoxic T-lymphocyte associated molecule-4 (CTLA-4) that inhibits cytotoxic responses. However, the regulation of CTLA-4 expression remains less well explored. We therefore studied the microRNA signature of circulating CD4(+) Tregs isolated from adult healthy donors and identified a signature composed of 15 differentially expressed microRNAs. Among those, miR-24, miR-145, and miR-210 were down-regulated in Tregs compared with controls and were found to have potential target sites in the 3'-UTR of FOXP3 and CTLA-4; miR-24 and miR-210 negatively regulated FOXP3 expression by directly binding to their two target sites in its 3'-UTR. On the other hand, miR-95, which is highly expressed in adult peripheral blood Tregs, positively regulated FOXP3 expression via an indirect mechanism yet to be identified. Finally, we showed that miR-145 negatively regulated CTLA-4 expression in human CD4(+) adult peripheral blood Tregs by binding to its target site in CTLA-4 transcript 3'-UTR. To our knowledge, this is the first identification of a human adult peripheral blood CD4(+) Treg microRNA signature. Moreover, unveiling one mechanism regulating CTLA-4 expression is novel and may lead to a better understanding of the regulation of this crucial gene.
