Abstract
BACKGROUND Bruxism is a repetitive masticatory muscles activity whose definition is being thoroughly reviewed in recent years. As in adults, two different forms of bruxism exist in children, namely awake and sleep bruxism. Scarcity of data, however,still persists about paediatric bruxism and no clear consensus has been developed. Therefore, the current review overviews the literature on bruxism in children tries to outline the state of art about this condition METHODS: Bruxism affects from 5% to 50% of the worldwide paediatric population. Sleep disturbances, parafunctional habits and psycho-social factors emerged to be the most likely associated factors with paediatric bruxism. Bruxism is characterised by several signs and symptoms variously combined, such as tooth wear and fractures, teeth impressions on soft tissues, temporomandibular disorders, headaches, behavioural and sleep disorders. About diagnosis, the most reliable tool in children remains the report of teeth grinding by parents or caregivers which must be accompanied by oral interview and accurate clinical examination. Electromyography and sleep polysomnography, albeit suitable in the diagnostic process, are not easy-to-use in children and are not strongly recommended. Currently, no evidence exists to support any kind of therapeutic options for bruxism in children. Management should be based on the identification of the underlying condition and conservative approaches are recommendable. CONCLUSION Notwithstanding the high prevalence, several aspects need to be further assessed in paediatric bruxism. Parental reports are still the most suitable diagnostic tool and conservative approaches are recommended in the management. Bruxism should be considered through a biopsychosocial model, and sleep, personality traits, stress and headaches are the factors towards whom research questions must be addressed to improve diagnosis and management.

Abstract
BACKGROUND B-raf inhibitors (BRAFi) are effective for BRAF-mutated papillary (PTC) and anaplastic (ATC) thyroid carcinomas, although acquired resistance impairs tumour cells' sensitivity and/or limits drug efficacy. Targeting metabolic vulnerabilities is emerging as powerful approach in cancer. METHODS In silico analyses identified metabolic gene signatures and Hif-1α as glycolysis regulator in PTC. BRAF-mutated PTC, ATC and control thyroid cell lines were exposed to HIF1A siRNAs or chemical/drug treatments (CoCl2, EGF, HGF, BRAFi, MEKi and diclofenac). Genes/proteins expression, glucose uptake, lactate quantification and viability assays were used to investigate the metabolic vulnerability of BRAF-mutated cells. RESULTS A specific metabolic gene signature was identified as a hallmark of BRAF-mutated tumours, which display a glycolytic phenotype, characterised by enhanced glucose uptake, lactate efflux and increased expression of Hif-1α-modulated glycolytic genes. Indeed, Hif-1α stabilisation counteracts the inhibitory effects of BRAFi on these genes and on cell viability. Interestingly, targeting metabolic routes with BRAFi and diclofenac combination we could restrain the glycolytic phenotype and synergistically reduce tumour cells' viability. CONCLUSION The identification of a metabolic vulnerability of BRAF-mutated carcinomas and the capacity BRAFi and diclofenac combination to target metabolism open new therapeutic perspectives in maximising drug efficacy and reducing the onset of secondary resistance and drug-related toxicity.

Abstract
Adipose tissue (AT) dysfunctions are associated with the onset of insulin resistance (IR) and type 2 diabetes mellitus (T2DM). Targeting glucose-dependent insulinotropic peptide receptor (GIPR) is a valid option to increase the efficacy of glucagon-like peptide 1 (GLP-1) receptor agonists in T2DM treatment. Nevertheless, the therapeutic potential of targeting the GIP/GIPR axis and its effect on the AT are controversial. In this work, we explored the expression and regulation of GIPR in precursor cells and mature adipocytes, investigating if and how obesogenic stimuli and thiazolidinediones perturb GIPR expression. Using publicly available gene expression datasets, we assessed that, among white adipose tissue (WAT) cells, adipocytes express lower levels of GIPR compared to cells of mesothelial origin, pericytes, dendritic and NK/T cells. However, we report that GIPR levels markedly increase during the in vitro differentiation of both murine and human adipocytes, from 3T3-L1 and human mesenchymal precursor cells (MSCs), respectively. Notably, we demonstrated that thiazolidinediones - ie. synthetic PPARγ agonists widely used as anti-diabetic drugs and contained in the adipogenic mix - markedly induce GIPR expression. Moreover, using multiple in vitro systems, we assessed that thiazolidinediones induce GIPR in a PPARγ-independent manner. Our results support the hypothesis that PPARγ synthetic agonists may be used to increase GIPR levels in AT, potentially affecting in turn the targeting of GIP system in patients with metabolic dysfunctions. Furthermore, we demonstrate in vitro and in vivo that proinflammatory stimuli, and especially the TNFα, represses GIPR both in human and murine adipocytes, even though discordant results were obtained between human and murine cellular systems for other cytokines. Finally, we demonstrated that GIPR is negatively affected also by the excessive lipid engulfment. Overall, we report that obesogenic stimuli - ie. pro-inflammatory cytokines and the increased lipid accumulation - and PPARγ synthetic ligands oppositely modulate GIPR expression, possibly influencing the effectiveness of GIP agonists.

Abstract
The view of long noncoding RNAs as nonfunctional "garbage" has been definitely outdated by the large body of evidence indicating this class of ncRNAs as "golden junk", especially in precision oncology. Indeed, in light of their oncogenic role and the higher expression in multiple cancer types compared with paired adjacent tissues, the clinical interest for lncRNAs as diagnostic and/or prognostic biomarkers has been rapidly increasing. The emergence of large-scale sequencing technologies, their subsequent diffusion even in small research and clinical centers, the technological advances for the detection of low-copy lncRNAs in body fluids, coupled to the huge reduction of operating costs, have nowadays made possible to rapidly and comprehensively profile them in multiple tumors and large cohorts. In this review, we first summarize some relevant data about the oncogenic role of well-studied lncRNAs having a clinical relevance. Then, we focus on the description of their potential use as diagnostic/prognostic biomarkers, including an updated overview about licensed patents or clinical trials on lncRNAs in oncology.

Abstract
While a low level of ROS plays a role in cellular regulatory processes, a high level can lead to oxidative stress and cellular dysfunction. Insulin resistance (IR) is one of the dysfunctions in which oxidative stress occurs and, until now, the factors underlying the correlation between oxidative stress and IR were unclear and incomplete. This study aims to explore this correlation in skeletal muscle, a tissue relevant to insulin-mediated glucose disposal, using the hyperthyroid rat as a model of oxidative stress. The development of IR in the liver from hyperthyroid animals has been widely reported, whereas data concerning the muscle are quite controversial. Thus, we investigated whether hyperthyroidism induces IR in skeletal muscle and the role of oxidative stress in this process. Particularly, we compared the effects of hyperthyroidism on IR both in the absence and presence of vitamin E (Vit E), acting as an antioxidant. Putative correlations between ROS production, oxidative stress markers, antioxidant capacity and changes in intracellular signalling pathways related to insulin action (AKT) and cellular stress response (EIF2α; JNK; PGC1α; BIP; and NRF1) were investigated. Moreover, we assessed the effects of hyperthyroidism and Vit E on the expression levels of genes encoding for glucose transporters (Slc2a1; Slc2a4), factors involved in lipid homeostasis and insulin signalling (Pparg; Ppara, Cd36), as well as for one of the IR-related inflammatory factors, i.e., interleukin 1b (Il1b). Our results suggest that hyperthyroidism-linked oxidative stress plays a role in IR development in muscle and that an adequate antioxidant status, obtained by vitamin E supplementation, that mitigates oxidative stress, may prevent IR development.

Abstract
BACKGROUND Temporomandibular disorders (TMDs) represent a common chronic complaint, which includes myofascial pain (MP). Although several therapeutical options have been proposed to control bruxism-related muscle hyperactivity, there is not enough evidence to define a standard approach. The present article describes the case of a 14-year old male patient with a history of painful mandibular close lock. CASE REPORT The patient was diagnosed with persistent myofascial pain in the left masseter, bilateral disc displacement with reduction, and retrodiscitis and capsulitis in the left temporomandibular joint. Awake and sleep bruxism were also present. Since first line treatments failed in managing the disorders, injections of onabotulinum toxin (BoNT-A ) were performed. After one month the pain decreased significantly and the jaw movements were restored. The patient was recommended to avoid hard and/or rubbery food, wide movements of the jaws and teeth clenching and to wear orthodontic appliance during the night since the joint damage was moderate. We report the 7-year follow-up demonstrating the long-term efficacy of a single injection of onabotulinum toxin in masseters and temporalis muscles in order to treat masticatory pain and dysfunctions. CONCLUSION The authors suggest that BoNT-A could be an optimum treatment for persistent MP and bruxism in young adolescents when first-line therapies fail.

Abstract
The growing incidence of diabetes mellitus worldwide implies the increasing prevalence of several related macro- (e.g., hypertension and atherosclerosis) and micro-vascular (e.g., nephropathy and retinopathy) complications. Notably, diabetic retinopathy (DR) is the leading cause of blindness in older diabetic patients and can occur with different degrees of severity. Chronic hyperglycemia is the main determinant of the functional damage of retinal cells. The oxidative stress, inflammatory factors and vascular endothelial growth factor signaling have been widely reported as contributors of DR onset and progression, and an emerging role has been described for different classes of non-coding RNA, including several long non-coding RNAs (lncRNAs). Here, we report the main results of all research articles (i.e., 150) listed on PubMed database from 2014 to 2022 regarding the putative role of lncRNAs in DR, including small nucleolar RNA host genes (SNHGs). Particularly, in this review we describe all lncRNAs and SNHGs with altered expression in DR and related contexts, discussing their association with DR outcomes, their mechanism of action related to DR, the molecular/functional effects, as well as the biological and experimental contexts. Thus, herein we provide an overview of the current state of knowledge regarding the putative involvement of 50 lncRNAs and SNHGs in the pathogenesis of DR, highlighting their potential as therapeutic targets or biomarkers for improving the clinical management of DR.

Abstract
Thyroid hormones are normally involved in glycaemic control, but their excess can lead to altered glucose metabolism and insulin resistance (IR). Since hyperthyroidism-linked increase in ROS results in tissue oxidative stress that is considered a hallmark of conditions leading to IR, it is conceivable a role of ROS in the onset of IR in hyperthyroidism. To verify this hypothesis, we evaluated the effects of vitamin E on thyroid hormone-induced oxidative damage, insulin resistance, and on gene expression of key molecules involved in IR in the rat liver. The factors involved in oxidative damage, namely the total content of ROS, the mitochondrial production of ROS, the activity of antioxidant enzymes, the in vitro susceptibility to oxidative stress, have been correlated to insulin resistance indices, such as insulin activation of hepatic Akt and plasma level of glucose, insulin and HOMA index. Our results indicate that increased levels of oxidative damage ROS content and production and susceptibility to oxidative damage, parallel increased fasting plasma level of glucose and insulin, reduced activation of Akt and increased activation of JNK. This last result suggests a role for JNK in the insulin resistance induced by hyperthyroidism. Furthermore, the variation of the genes Pparg, Ppara, Cd36 and Slc2a2 could explain, at least in part, the observed metabolic phenotypes.

Abstract
Low-grade chronic inflammation and reduced differentiation capacity are hallmarks of hypertrophic adipose tissue (AT) and key contributors of insulin resistance. We identified PPARGΔ5 as a dominant-negative splicing isoform overexpressed in the AT of obese/diabetic patients able to impair adipocyte differentiation and PPARγ activity in hypertrophic adipocytes. Herein, we investigate the impact of macrophage-secreted pro-inflammatory factors on PPARG splicing, focusing on PPARGΔ5. We report that the epididymal AT of LPS-treated mice displays increased PpargΔ5/cPparg ratio and reduced expression of Pparg-regulated genes. Interestingly, pro-inflammatory factors secreted from murine and human pro-inflammatory macrophages enhance the PPARGΔ5/cPPARG ratio in exposed adipogenic precursors. TNFα is identified herein as factor able to alter PPARG splicing—increasing PPARGΔ5/cPPARG ratio—through PI3K/Akt signaling and SRp40 splicing factor. In line with in vitro data, TNFA expression is higher in the SAT of obese (vs. lean) patients and positively correlates with PPARGΔ5 levels. In conclusion, our results indicate that inflammatory factors secreted by metabolically-activated macrophages are potent stimuli that modulate the expression and splicing of PPARG. The resulting imbalance between canonical and dominant negative isoforms may crucially contribute to impair PPARγ activity in hypertrophic AT, exacerbating the defective adipogenic capacity of precursor cells.

Abstract
BACKGROUND Excessive adiposity provides an inflammatory environment. However, in people with severe obesity, how systemic and local adipose tissue (AT)-derived cytokines contribute to worsening glucose tolerance is not clear. METHODS Ninty-two severely obese (SO) individuals undergoing bariatric surgery were enrolled and subjected to detailed clinical phenotyping. Following an oral glucose tolerance test, participants were included in three groups, based on the presence of normal glucose tolerance (NGT), impaired glucose tolerance (IGT), or type 2 diabetes (T2D). Serum and subcutaneous AT (SAT) biopsies were obtained and mesenchymal stem cells (MSCs) were isolated, characterized, and differentiated in adipocytes in vitro. TNFA and PPARG mRNA levels were determined by qRT-PCR. Circulating, adipocyte- and MSC-released cytokines, chemokines, and growth factors were assessed by multiplex ELISA. RESULTS Serum levels of IL-9, IL-13, and MIP-1β were increased in SO individuals with T2D, as compared with those with either IGT or NGT. At variance, SAT samples obtained from SO individuals with IGT displayed levels of TNFA which were threefold higher compared to those with NGT, but not different from those with T2D. Elevated levels of TNFα were also found in differentiated adipocytes, isolated from the SAT specimens of individuals with IGT and T2D, compared to those with NGT. Consistent with the pro-inflammatory milieu, IL-1β and IP-10 secretion was significantly higher in adipocytes from individuals with IGT and T2D. Moreover, increased levels of TNFα, both mRNA and secreted protein were detected in MSCs obtained from IGT and T2D, compared to NGT SO individuals. Exposure of T2D and IGT-derived MSCs to the anti-inflammatory flavonoid quercetin reduced TNFα levels and was paralleled by a significant decrease of the secretion of inflammatory cytokines. CONCLUSION In severe obesity, enhanced SAT-derived inflammatory phenotype is an early step in the progression toward T2D and maybe, at least in part, attenuated by quercetin.

Abstract
PURPOSE OF REVIEW Full and partial synthetic agonists targeting the transcription factor PPARγ are contained in FDA-approved insulin-sensitizing drugs and used for the treatment of metabolic syndrome-related dysfunctions. Here, we discuss the association between PPARG genetic variants and drug efficacy, as well as the role of alternative splicing and post-translational modifications as contributors to the complexity of PPARγ signaling and to the effects of synthetic PPARγ ligands. RECENT FINDINGS PPARγ regulates the transcription of several target genes governing adipocyte differentiation and glucose and lipid metabolism, as well as insulin sensitivity and inflammatory pathways. These pleiotropic functions confer great relevance to PPARγ in physiological regulation of whole-body metabolism, as well as in the etiology of metabolic disorders. Accordingly, PPARG gene mutations, nucleotide variations, and post-translational modifications have been associated with adipose tissue disorders and the related risk of insulin resistance and type 2 diabetes (T2D). Moreover, PPARγ alternative splicing isoforms-generating dominant-negative isoforms mainly expressed in human adipose tissue-have been related to impaired PPARγ activity and adipose tissue dysfunctions. Thus, multiple regulatory levels that contribute to PPARγ signaling complexity may account for the beneficial as well as adverse effects of PPARγ agonists. Further targeted analyses, taking into account all these aspects, are needed for better deciphering the role of PPARγ in human pathophysiology, especially in insulin resistance and T2D. The therapeutic potential of full and partial PPARγ synthetic agonists underlines the clinical significance of this nuclear receptor. PPARG mutations, polymorphisms, alternative splicing isoforms, and post-translational modifications may contribute to the pathogenesis of metabolic disorders, also influencing the responsiveness of pharmacological therapy. Therefore, in the context of the current evidence-based trend to personalized diabetes management, we highlight the need to decipher the intricate regulation of PPARγ signaling to pave the way to tailored therapies in patients with insulin resistance and T2D.

Abstract
BACKGROUD Juvenile Idiopathic Arthritis (JIA) encompasses a wide range of mostly idiopathic autoimmune arthritis which affect growing individuals. Temporomandibular disorders are a diffuse spectrum of diseases which involve temporomandibular joint (TMJ) and associated structures. However, much more need to be defined in order to detect and manage these conditions. Albeit satisfying evidences exist about their impact on the adult population, there is great lack of information in children. The current study has been developed in order to overview what it is known about these disorders and their mutual interactions. A case report as support to the scientific evidence has been further described. CASE REPORT A 7-year-old patient affected by an undifferentiated form of JIA developed arthritis to TMJs, complaining pain and functional impairments. After 2 years, the follow-up with combined pharmacological therapies and a modified oral stabilisation appliance shows no objective worsening of the joints' structures. However, the more complex symptomatic management of inflammation highlights the need for further knowledge. CONCLUSION The present study shows that both literature and clinical activity highlight a strong relationship between JIA and TMDs, that can affect the quality of life of children and adolescents. Diagnosis and management of these conditions are extremely complex, thus additional studies and evidence are needed. However, the need of an interdisciplinary approach between rheumatologists, paediatricians and dentists has been demonstrated.

Abstract
Sequencing-based transcriptomics has significantly redefined the concept of genome complexity, leading to the identification of thousands of lncRNA genes identification of thousands of lncRNA genes whose products possess transcriptional and/or post-transcriptional regulatory functions that help to shape cell functionality and fate. Indeed, it is well-established now that lncRNAs play a key role in the regulation of gene expression through epigenetic and posttranscriptional mechanims. The rapid increase of studies reporting lncRNAs alteration in cancers has also highlighted their relevance for tumorigenesis. Herein we describe the most prominent examples of well-established lncRNAs having oncogenic and/or tumor suppressive activity. We also discuss how technical advances have provided new therapeutic strategies based on their targeting, and also report the challenges towards their use in the clinical settings.

Abstract
Reduced neo-adipogenesis and dysfunctional lipid-overloaded adipocytes are hallmarks of hypertrophic obesity linked to insulin resistance. Identifying molecular features of hypertrophic adipocytes requires appropriate in vitro models. We describe the generation of a model of human hypertrophic-like adipocytes directly comparable to normal adipose cells and the pathologic evolution toward hypertrophic state. We generate in vitro hypertrophic cells from mature adipocytes, differentiated from human mesenchymal stem cells. Combining optical, confocal, and transmission electron microscopy with mRNA/protein quantification, we characterize this cellular model, confirming specific alterations also in subcutaneous adipose tissue. Specifically, we report the generation and morphological/molecular characterization of human normal and hypertrophic-like adipocytes. The latter displays altered morphology and unbalance between canonical and dominant negative (PPARGΔ5) transcripts of PPARG, paralleled by reduced expression of PPARγ targets, including GLUT4. Furthermore, the unbalance of PPARγ isoforms associates with GLUT4 down-regulation in subcutaneous adipose tissue of individuals with overweight/obesity or impaired glucose tolerance/type 2 diabetes, but not with normal weight or glucose tolerance. In conclusion, the hypertrophic-like cells described herein are an innovative tool for studying molecular dysfunctions in hypertrophic obesity and the unbalance between PPARγ isoforms associates with down-regulation of GLUT4 and other PPARγ targets, representing a new hallmark of hypertrophic adipocytes.

Abstract
Background A novel prediction algorithm is needed for the identification of effective tumor associated mutated neoantigens. Only those with no homology to self wild type antigens are true predicted neoantigens (TPNAs) and can elicit an antitumor T cell response, not attenuated by central tolerance. To this aim, the mutational landscape was evaluated in HCV-associated hepatocellular carcinoma. Methods Liver tumor biopsies and adjacent non-tumor liver tissues were obtained from 9 HCV-chronically infected subjects and subjected to RNA-Seq analysis. Mutant peptides were derived from single nucleotide variations and TPNAs were predicted using two prediction servers (e.g. NetTepi and NetMHCstabpan) by comparison with corresponding wild-type sequences, non-related self and pathogen-related antigens. Immunological confirmation was obtained in preclinical as well as clinical setting. Results The development of such an improved algorithm resulted in a handful of TPNAs despite the large number of predicted neoantigens. Furthermore, TPNAs may share homology to pathogen’s antigens and be targeted by a pre-existing T cell immunity. Cross-reactivity between such antigens was confirmed in an experimental pre-clinical setting. Finally, TPNAs homologous to pathogen’s antigens were found in the only HCC long-term survival patient, suggesting a correlation between the pre-existing T cell immunity specific for these TPNAs and the favourable clinical outcome. Conclusions The new algorithm allowed the identification of the very few TPNAs in cancer cells, and those targeted by a pre-existing immunity strongly correlated with long-term survival. Only such TPNAs represent the optimal candidates for immunotherapy strategies.

Abstract
To prevent arteriovenous fistula (AVF) early failure, due to radial or brachial artery stenosis, ultrasound guided angioplasty performed while surgically creating the AVF could be an effective procedure. Case report A 76-year-old diabetic male patient, on hemodialysis (HD) for 15 months, presented extensive thrombosis of the radio-cephalic AVF at the right arm, which had lasted for about 10 days. Ultrasound examination showed a 40% brachial artery stenosis with eccentric calcified plaque. The stenosis was localized about 1.5 cm before the artery bifurcation. The brachial artery diameter was 0.45 cm before and 0.26 cm at the level of the stenosis, the latter being 0.45 cm long. At the left wrist, under local anesthesia, the radial artery and the cephalic vein were exposed; the radial artery was then longitudinally incised for 7–8 mm in the area selected to create the AVF. A 6 Fr introducer, a metallic guide wire and a catheter for angioplasty were inserted one after the other in the radial artery. When the correct position of the angioplasty catheter in the stenotic area was established by ultrasound examination, the balloon was blown up to 13 atm for 35 sec, reducing the stenosis from 40–20%. Finally, a side-to-side radio-cephalic fistula was created, legating the distal vein. The AVF was used for HD after 3 weeks. The follow-up at 6 months demonstrated fair access performance and it was used without problems. Our satisfactory experience suggests that ultrasound guided angioplasty of brachial artery stenosis, performed simultaneously with surgical AVF creation, is possibly a successful procedure. This technique reduces the risk of early AVF failure and also allows, when required, stent implantation.

Abstract
BACKGROUND Despite left ventricular (LV) dysfunction contributing to mortality in chronic heart failure (HF), the molecular mechanisms of LV failure continues to remain poorly understood and myocardial biomarkers have yet to be identified. The aim of this pilot study was to investigate specific transcriptome changes occurring in cardiac tissues of patients with HF compared to healthy condition patients to improve diagnosis and possible treatment of affected subjects. METHODS Unlike other studies, only dilated cardiomyopathy (DCM) (n = 2) and restrictive cardiomyopathy (RCM) (n = 2) patients who did not report family history of the disease were selected with the aim of obtaining a homogeneous population for the study. The transcriptome of all patients were studied by RNA-sequencing (RNA-Seq) and the read counts were adequately filtered and normalized using a recently developed user-friendly tool for RNA-Seq data analysis, based on a new graphical user interface (RNA-SeqGUI). RESULTS By using this approach in a pairwise comparison with healthy donors, we were able to identify DCM- and RCM-specific expression signatures for protein-coding genes as well as for long noncoding RNAs (lncRNAs). Differential expression of 5 genes encoding different members of the mediator complex was disclosed in this analysis. Interestingly, a significant alteration was found for genes which had never been associated with HF until now, and 27 lncRNA/mRNA pairs that were significantly altered in HF patients. CONCLUSIONS The present findings revealed specific expression pattern of both protein-coding and lncRNAs in HF patients, confirming that new LV myocardial biomarkers could be reliably identified using Next-Generation Sequencing-based approaches.

Abstract
Abstract
A novel two-step bioinformatics strategy was applied for identification of signatures with therapeutic implications in hepatitis-associated HCC. Transcriptional profiles from HBV- and HCV-associated HCC samples were compared with normal liver tissue controls. Resulting HCC modulated genes were subsequently compared with different normal tissue samples. Two related signatures were identified, namely “HCC-associated” and “HCC-specific.” Expression data were validated by RNA-Seq analysis carried out on unrelated HCC samples and protein expression was confirmed according to the publicly available database at http://www.proteinatlas.org/. Among all, only two proteins (namely AKR1B10 and IGF2BP3) were found strictly HCC-specific with no expression in 18/20 normal tissues. Target peptides for vaccine design were predicted for both proteins associated with the most prevalent HLA-class I and II alleles. The described novel strategy showed to be feasible for identification of HCC-specific proteins as highly potential target for HCC immunotherapy (Petrizzo et al., Scientific Reports, in press).

Abstract
Transcriptome studies have shown the pervasive nature of transcription, demonstrating almost all the genes undergo alternative splicing. Accurately annotating all transcripts of a gene is crucial. It is needed to understand the impact of mutations on phenotypes, to shed light on genetic and epigenetic regulation of mRNAs and more generally to widen our knowledge about cell functionality and tissue diversity. RNA-sequencing (RNA-Seq), and the other applications of the next-generation sequencing, provides precious data to improve annotations' accuracy, simultaneously creating issues related to the variety, complexity and the size of produced data. In this ‘scenario’, the lack of user-friendly resources, easily accessible to researchers with low skills in bioinformatics, makes difficult to retrieve complete information about one or few genes without browsing a jungle of databases. Concordantly, the increasing amount of data from ‘omics’ technologies imposes to develop integrated databases merging different data formats coming from distinct but complementary sources. In light of these considerations, and given the wide interest in studying Down syndrome—a genetic condition due to the trisomy of human chromosome 21 (HSA21)—we developed an integrated relational database and a web interface, named ALE-HSA21 (AnaLysis of Expression on HSA21), accessible at http://bioinfo.na.iac.cnr.it/ALE-HSA21. This comprehensive and user-friendly web resource integrates—for all coding and noncoding transcripts of chromosome 21—existing gene annotations and transcripts identified de novo through RNA-Seq analysis with predictive computational analysis of regulatory sequences. Given the role of noncoding RNAs and untranslated regions of coding genes in key regulatory mechanisms, ALE-HSA21 is also an interesting web-based platform to investigate such processes. The ‘transcript-centric’ and easily-accessible nature of ALE-HSA21 makes this resource a valuable tool to rapidly retrieve data at the isoform level, rather than at gene level, useful to investigate any disease, molecular pathway or cell process involving chromosome 21 genes.

Abstract
Neurodegenerative disorders and cancer are severe diseases threatening human health. The glaring differences between neurons and cancer cells mask the processes involved in their pathogenesis. Defects in cell cycle, DNA repair, and cell differentiation can determine unlimited proliferation in cancer, or conversely, compromise neuronal plasticity, leading to cell death and neurodegeneration. Alteration in regulatory networks affecting gene expression contribute to human diseases onset, including neurodegenerative disorders, and deregulation of non-coding RNAs – particularly microRNAs (miRNAs) – is supposed to have a significant impact. Recently, competitive endogenous RNAs (ceRNAs) – acting as sponges – have been identified in cancer, indicating a new and intricate regulatory network. Given that neurodegenerative disorders and cancer share altered genes and pathways, and considering the emerging role of miRNAs in neurogenesis, we hypothesize ceRNAs may be implicated in neurodegenerative diseases. Here we propose, and computationally predict, such regulatory mechanism may be shared between the diseases. It is predictable that similar regulation occurs in other complex diseases, and further investigation is needed.

Abstract
Peroxisome proliferator-activated receptor gamma (PPARγ) is one of the most extensively studied ligand-inducible transcription factors (TFs), able to modulate its transcriptional activity through conformational changes. It is of particular interest because of its pleiotropic functions: it plays a crucial role in the expression of key genes involved in adipogenesis, lipid and glucid metabolism, atherosclerosis, inflammation, and cancer. Its protein isoforms, the wide number of PPARγ target genes, ligands, and coregulators contribute to determine the complexity of its function. In addition, the presence of genetic variants is likely to affect expression levels of target genes although the impact of PPARG gene variations on the expression of target genes is not fully understood. The introduction of massively parallel sequencing platforms-in the Next Generation Sequencing (NGS) era-has revolutionized the way of investigating the genetic causes of inherited diseases. In this context, DNA-Seq for identifying-within both coding and regulatory regions of PPARG gene-novel nucleotide variations and haplotypes associated to human diseases, ChIP-Seq for defining a PPARγ binding map, and RNA-Seq for unraveling the wide and intricate gene pathways regulated by PPARG, represent incredible steps toward the understanding of PPARγ in health and disease.

Abstract
To determine factors predictive of long-term graft function in patients treated prophylactically with an antilymphocyte antibody, 670 first cadaveric adult renal transplant procedures performed between 1985 and 1991 were reviewed. The actuarial 1- and 5-year patient survival in this group was 95% and 87% respectively, and graft survival was 84% and 70% respectively. The final analysis was based on a study group of 635 patients which excluded 28 patients who lost grafts to early technical failures and 8 patients who were not induced with an antilymphocyte preparation. Multivariate analysis showed that 5-year graft survival was lower in patients with delayed graft function (p = 0.0001), in those who had an acute rejection episode in the first 6 months post-transplant (p = 0.0001), recipients greater than 55 years of age at the time of transplant (p = 0.0001), in patients who were highly sensitized at the time of transplant (p = 0.0331) and, finally, in those who received a graft from an older donor (p = 0.044). The 209 patients with delayed graft function had a 16% lower long-term graft survival than 425 patients with early graft function (62% vs. 78% respectively at 5 years). One or more rejection episodes in the first 6 months post-transplant (329 patients) reduced long-term graft survival by 13% compared to those who did not have a rejection episode (67% vs. 80% respectively at 5 years).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A total 166 first cadaveric renal allograft recipients were randomly assigned to receive either rabbit antithymocyte serum (RATS) (n = 83) or OKT3 (n = 83) for 10 to 14 days after transplant as prophylaxis against rejection. Both groups were similar with respect to age, sex, donor age, diabetes, time on dialysis, panel-reactive antibody, HLA matching, and transfusion before transplantation. All patients were followed for 1 year after transplantation. A comparison of the rejection rates between the 2 groups of patients showed that patients receiving OKT3 had a rate of first rejection 1.87 times higher than those receiving RATS (95% confidence interval 1.18-2.8, P = 0.007). Twenty-five steroid-resistant rejections occurred in OKT3-treated patients as compared with 12 in the RATS-treated group (P < 0.05). There was no significant difference in early or late renal function between the 2 groups of patients. Actuarial 1-year graft survival for the RATS group was 78% and for the OKT3 group, 80.7% (P = NS). Actuarial 1-year patient survival was similar: 89.5% in the RATS group and 94.6% in the OKT3 group (P = NS). Total hospitalization time was 29.8 +/- 19.9 days for RATS vs. 39.5 +/- 22.1 days for those treated with OKT3 (P < 0.006). A number of infections were observed but there were no significant differences between the groups. We conclude that RATS provides better prophylaxis than OKT3 in first cadaveric renal transplants because it is associated with fewer rejection episodes, less hospitalization, and no additional morbidity or mortality.

Abstract
We performed a multicenter study to investigate the problem of cadaver kidney transplants that never achieve function, or that recover after a period of delayed function, and we used multivariate techniques to model the results. Sixty-nine patients who received cadaver kidney transplants that never functioned (NF) were compared with 69 kidney recipients with early graft function (EF), and 69 with delayed but recovering graft function (DF), matched for transplant hospital and time. The results were analyzed using an unconditional logistic regression model. Risk factors for never-function transplants compared to immediate-function transplants were as follows: previous failed transplant, no polyclonal antilymphocyte globulin (ALG) prophylaxis, increasing anastomosis time, decreasing donor blood pressure, and prior transfusions in first but not subsequent transplant recipients. When technical failures were excluded, 88% of NF grafts displayed severe rejection, suggesting that rejection in a poorly functioning kidney is the principal cause of the NF outcome. Risk factors for delayed function compared to immediate function were these: increasing anastomosis time, no ALG, increasing total cold ischemia time, duration of end-stage renal disease (ESRD), and male sex. Thus ischemic and immunologic risk factors contributed to the DF and NF outcomes. This study suggests that efforts to reduce the delayed and never-function outcomes should be directed to the use of ALG prophylaxis and to the reduction of cold ischemia and anastomosis times, particularly in recipients who have lost a previous transplant.

Abstract
In a randomized trial conducted in 9 Ontario transplant centers, 107 cadaver kidney donors were randomized so that both kidneys were preserved either by simple cold storage (CS) or by pulsatile perfusion (PP). After exclusions and losses to follow-up, there were 90 patients in the CS group and 91 in the PP group. Total preservation times were similar in the two groups (27.7 +/- 12 and 30.5 +/- 10 hr), as was the proportion of kidneys with long (greater than 36 hr) storage times (21% and 26%). Twelve-month graft survival was 70% for CS and 75% for PP (not significant, NS); patient survival was 89% for CS and 95% for PP (NS). The incidence of kidneys that never functioned was also similar in the two groups (14% vs. 15%, respectively). However, the risk of early, reversible graft dysfunction was significantly higher for CS (44%) than for PP (31%). The same effect was observed with two independent methods of assessment of graft function. The chief effect of PP on renal function was in reduction of the mean serum creatinine at 1 week (632 mumol/L for CS vs. 403 mumol/L for PP, P less than .001). There was no significant influence of storage mode on the rapidity of urine output or number of dialyses required. No apparent effect of cyclosporine on the results with either preservation method was seen. We conclude that the case for retention of PP for kidney preservation now rests on its ability to achieve slightly better initial function than CS. However, the mild dysfunction observed with CS did not appear to translate into long-term detriment. When these considerations are weighed against the increased cost of PP, the advantage may lie with cold storage.

Abstract
Donor-specific alloantibody was monitored in recipients of 81 renal allografts by 51Cr release assays. Complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity were both followed. In addition to the conventional lymphoid target cells nonlymphoid target cells, namely fibroblasts from the donor, were used. Although antibody against donor lymphoid cells was found more frequently, associations with graft loss and with rejection were greater with antibody against fibroblasts. The superior association of antibody against fibroblasts with clinical events suggests that wider use of nonlymphoid target cells would be of value in studies of alloantibody responses in renal transplant recipients.

Abstract
Donor-specific alloantibody responses were studied in 55 patients receiving their first cadaver kidney transplant, using 51Cr release assays for complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity against two types of donor targets: fibroblasts and lymphoid cells. When patients with pretransplant donor-specific antibody were excluded, the alloantibody responses were significantly more frequent in recipients of blood group A kidneys than in recipients of non-A (P = .004). The association was seen with both lymphocyte and fibroblast target cells, but was stronger when fibroblast targets were used. The association could not be explained adequately by differences in transfusion status or in graft survival between the A and non-A groups. The results suggest that certain types of alloantibody response against the graft are more vigorous in recipients of group A kidneys than in other recipients. Such responses may contribute to the tendency of group A patients to show poorer graft survival in some studies.

Abstract
In testing for donor-specific alloantibody in renal transplantation we discovered that sera of many recipients lysed their own fibroblasts in complement-dependent cytotoxicity. The incidence of this autoreactivity before and during the first month post-transplant was 15 and 10% respectively, but rose to 48% after 2 months. There was a significant association between autoantibody formation and the presence of donor-specific alloantibody, but no association between autoantibody and graft survival. Autoantibody reactive with fibroblasts was three times more frequent than lymphocytotoxic autoantibody, and showed no association with the presence of such antibody, indicating that these autoantibodies were directed against different antigens. Reduction with 2-mercaptoethanol indicated that much of the autoreactivity was IgM. By absorption tests the autoantigen was shown to be expressed extensively on fibroblasts, but not on lymphocytes, platelets or red cells. Susceptibility to lysis by the autoantibody varied from day to day in the fibroblasts of a particular individual, and also varied from individual to individual. These results are of interest because they indicate that autoantibody formation in human renal allografts may result from chronic allogeneic stimulation, and that the antibody may be detecting a previously unknown fibroblast antigen.

Abstract
Donor specific alloantibody was monitored in 40 kidney transplants for 3 most post-transplant. Two 51Cr release assays were used: complement-dependent lysis and antibody-dependent cell-mediated cytotoxicity. Fibroblast, lymphocyte, and lymphoblast target cells were all tested whenever possible. Antibody was detected in only 6 of 22 patients who achieved satisfactory function (creatinine less than 3 at 3 mos), but in 15 of 18 patients who had an unfavorable outcome (return to dialysis or creatinine greater than 3 at 3 mos). The association of antifibroblast antibody with poor function was particularly striking: in the 33 patients in whom donor fibroblasts were tested, none of 20 with good function had detectable antibody, whereas 10 of 16 with graft loss or poor function had detectable antibody. Studies with mouse fibroblasts indicated that the association of antifibroblast antibody with graft destruction may be explainable in terms of selective expression of various alloantigens on fibroblasts.
