Abstract
BARD1 is associated with the development of high-risk neuroblastoma patients. Particularly, the expression of full length (FL) isoform, FL BARD1, correlates to high-risk neuroblastoma development and its inhibition is sufficient to induce neuroblastoma cells towards a worst phenotype. Here we have investigated the mechanisms of FL BARD1 in neuroblastoma cell lines depleted for FL BARD1 expression. We have shown that FL BARD1 expression protects the cells from spontaneous DNA damage and from damage accumulated after irradiation. We demonstrated a role for FL BARD1 as tumor suppressor to prevent unscheduled mitotic entry of DNA damaged cells and to lead to death cells that have bypassed cell cycle checkpoints. FL BARD1-depleted cells that have survived to checkpoints acquire features of aggressiveness. Overall, our results show that FL BARD1 may defend cells against cancer and prevent malignant transformation of cells.

Abstract
We have carried out a retrospective study of chromosome anomalies associated with increased nuchal translucency (NT) in order to compare yield rates of karyotype, chromosome microarray analysis (CMA), and non-invasive prenatal testing (NIPT) in this condition. Presenting with increased NT or cystic hygroma ≥3.5 mm as an isolated sign, 249 fetuses underwent karyotype and/or CMA from 11 to 18 gestational weeks. Karyotype and fluorescence in situ hybridization (FISH) analyses detected 103 chromosomal anomalies including 95 aneuploidies and eight chromosomal rearrangements or derivatives. Further, seven pathogenic copy number variants (CNV), five likely pathogenic CNVs, and 15 variants of unknown significance (VOUS) were detected by CMA in fetuses with normal karyotype. Genetic testing is now facing new challenges due to results with uncertain clinical impacts. Additional investigations will be necessary to interpret these findings. More than 15% of the anomalies that we have diagnosed with invasive techniques could not be detected by NIPT. It is therefore definitely not recommended in the case of ultrasound anomalies. These results, while corroborating the use of CMA in fetuses with increased NT as a second tier after rapid aneuploidy testing, do not suggest a dismissal of karyotype analysis.

Abstract
In this study, we verify the association between the rs1333049 single nucleotide polymorphism (9p21.3) within CDKN2A-CDKN2B and coronary artery disease (CAD) in an Italian population. We replicated rs1333049_G allele association with a significantly reduced risk of CAD (OR = 0.816; 95% confidence interval [0.705-0.945]; p = 0.0065) in 711 CAD patients and 755 normal healthy individuals. This effect is maintained even stratifying patients by gender and by risk factors. A significant association was found with age of CAD onset. Interestingly, we found a protective trend of association between the rs1333049_G allele and peripheral artery disease, a progressive atherosclerotic condition in which plaque builds up in the arteries that carry blood to the head, organs, and limbs (OR = 0.724; 95% CI [0.520-1.007]; p = 0.054). No genotype-phenotype association was found with more severe CAD clinical parameters. If certain genetic factors predispose individuals to adverse outcomes, the knowledge of a patient's genotype may influence clinical management.

Abstract
Hypoxia inducible factor (HIF)-2α protein expression in solid tumors promotes stem-like phenotype in cancer stem cells and increases tumorigenic potential in nonstem cancer cells. Recently, we have shown that HIF-1/2α gene expression is correlated to neuroblastoma (NB) poor survival and to undifferentiated tumor state; HIF-2α protein was demonstrated to enhance aggressive features of the disease. In this study, we used proteomic experiments on NB cells to investigate HIF-2α downstream-regulated proteins or pathways with the aim of providing novel therapeutic targets or bad prognosis markers. We verified that pathways mostly altered by HIF-2α perturbation are involved in tumor progression. In particular, HIF-2α induces alteration of central metabolism and splicing control pathways. Simultaneously, WNT, RAS/MAPK, and PI3K/AKT activity or expression are affected and may impact the sensitivity and the intensity of HIF-2α-regulated pathways. Furthermore, genes coding the identified HIF-2α-related markers built a signature able to stratify NB patients with unfavorable outcome. Taken together, our findings underline the relevance of dissecting the downstream effects of a poor survival marker in developing targeted therapy and improving patient stratification. Future prospective studies are needed to translate the use of these data into the clinical practice.

Abstract
CD55 has been revealed to have an important role in tumor genesis, and presence of small populations of cells with strong CD55 expression would be sufficient to predict poor prognosis of several tumors. In our study we revealed that CD55 is a novel target of hypoxia-inducible factor HIF-2α in neuroblastoma (NB) cells. We show that HIF-2α expression is sufficient to sustain stem-like features of NB cells, whereas CD55 protein upon HIF-2α expression contributes to growth of colonies and to invasion of cells, but not to stemness features. Interestingly, in NB tissues, CD55 expression is limited to quite a small population of cells that are HIF-2α positive, and the gene expression of CD55 in the NB data set reveals that the presence of CD55(high) affects prognosis of NB patients. The functional characterization of CD55-positive populations within heterogeneous NB monoclonal cell lines shows that CD55 has pro-invading and anti-adhesive properties that might provide the basis for the ability of solid tumors to survive as microscopic residual disease. The easy accessibility to CD55 membrane antigen will offer the possibility of a novel antibody approach in the treatment of recurrent tumors and will provide a ready target for antibody-based visualization in NB diagnosis and prognosis.

Abstract
The genetic etiology of sporadic neuroblastoma is still largely obscure. In a genome-wide association study, we identified single-nucleotide polymorphisms (SNP) associated with neuroblastoma at the CASC15, BARD1, LMO1, DUSP12, HSD17B12, HACE1, and LIN28B gene loci, but these explain only a small fraction of neuroblastoma heritability. Other neuroblastoma susceptibility genes are likely hidden among signals discarded by the multiple testing corrections. In this study, we evaluated eight additional genes selected as candidates for further study based on proven involvement in neuroblastoma differentiation. SNPs at these candidate genes were tested for association with disease susceptibility in 2,101 cases and 4,202 controls, with the associations found replicated in an independent cohort of 459 cases and 809 controls. Replicated associations were further studied for cis-effect using gene expression, transient overexpression, silencing, and cellular differentiation assays. The neurofilament gene NEFL harbored three SNPs associated with neuroblastoma (rs11994014: Pcombined = 0.0050; OR, 0.88; rs2979704: Pcombined = 0.0072; OR, 0.87; rs1059111: Pcombined = 0.0049; OR, 0.86). The protective allele of rs1059111 correlated with increased NEFL expression. Biologic investigations showed that ectopic overexpression of NEFL inhibited cell growth specifically in neuroblastoma cells carrying the protective allele. NEFL overexpression also enhanced differentiation and impaired the proliferation and anchorage-independent growth of cells with protective allele and basal NEFL expression, while impairing invasiveness and proliferation of cells homozygous for the risk genotype. Clinically, high levels of NEFL expression in primary neuroblastoma specimens were associated with better overall survival (P = 0.03; HR, 0.68). Our results show that common variants of NEFL influence neuroblastoma susceptibility and they establish that NEFL expression influences disease initiation and progression.

Abstract
The Authors report the clinical case of a patient with a deficit of humoral immunity who developed infections since puberty. The serum levels of IgG and IgA decreased progressively in the fourth decade of life, while serum IgM increased. Moreover, the patient developed a marked CD4+ T lymphocytopenia and a meager B lymphocytopenia, vitiligo, positivity for anti-SSA/Ro autoantibodies and granulomatous phlogosis of the knee. The heterogeneity of the clinical and laboratory data suggests that this patient might present an overlap immunodeficiency syndrome with some of the clinical and immunological features typical of the hyper-IgM syndrome (in the X-linked or autosomal forms) and others that can be referred to a nosologically distinct humoral immunodeficiency such as the common variable immunodeficiency.

Abstract
Newborns are more susceptible than adults to infections, which suggests a relative immaturity of the immune system early after birth. Cord blood T cells differ significantly both in surface phenotype and function from adult T cells. We examined the proliferation and expression of activation molecules by lymphocytes isolated from umbilical cord blood or peripheral blood of adults. The lymphocytes were cultured for 5 days in the presence of phytohemagglutinin, concanavalin A, or anti-CD3 monoclonal antibody. Cord blood T cells expressed the CD45RA molecule, while a low proportion expressed the RO isoform, a marker of primed or activated lymphocytes. Furthermore, more than 95% of neonatal lymphocytes bear the CD38 molecule, but do not express the CD57 molecule. After stimulation by phytohemagglutinin or concanavalin A, the lymphocytes from newborns were activated and proliferated as efficiently as adult T cells. Anti-CD3 did not cause neonatal lymphocytes to proliferate, but these cells expressed activation molecules, such as HLA-DR antigens and the receptor for interleukin-2 and transferrin. The relevance of these findings to tolerance induction in immature cord blood T cells is discussed.
