Abstract
BACKGROUND Neuroblastoma (NB) is a paediatric tumour of the sympathetic nervous system. Half of all cases are defined high-risk with an overall survival less than 40% at 5 years from diagnosis. The lack of in vitro models able to recapitulate the intrinsic heterogeneity of primary NB tumours has hindered progress in understanding disease pathogenesis and therapy response. METHODS Here we describe the establishment of 6 patient-derived organoids (PDOs) from cells of NB tumour biopsies capable of self-organising in a structure resembling the tissue of origin. RESULTS PDOs recapitulate the histological architecture typical of the NB tumour. Moreover, PDOs expressed NB specific markers such as neural cell adhesion molecules, NB84 antigen, synaptophysin (SYP), chromogranin A (CHGA) and neural cell adhesion molecule NCAM (CD56). Analyses of whole genome genotyping array revealed that PDOs maintained patient-specific chromosomal aberrations such as MYCN amplification, deletion of 1p and gain of chromosome 17q. Furthermore, the PDOs showed stemness features and retained cellular heterogeneity reflecting the high heterogeneity of NB tumours. CONCLUSIONS We were able to create a novel preclinical model for NB exhibiting self-renewal property and allowing to obtain a reservoir of NB patients' biological material useful for the study of NB molecular pathogenesis and to test drugs for personalised treatments.

Abstract
The quantitative uptake of Silica nanoparticles (SiNPs), although representing an essential prerequisite for their theranostic use, is difficult to address and it is still not utterly investigated. In this study, we tested the uptake and toxicity of two different types of luminescent core-shell silica-PEG (polyethylene glycol) nanoparticles SiNP and their carboxylate analogues on human adenocarcinoma cell line LoVo. We assessed the intracellular spatial distribution and concentration of Si element in the cell by a state-of-the-art approach merging synchrotron-based X-ray techniques (XRFM) with scanning transmission X-Ray microscopy (STXM). The concentration maps of Si obtained reflect the distribution of the SiNPs. In addition, we calculated the number of SiNPs per volume unit in each single cell, quantitating the exact amount of conveyed particles. The absence of effects on proliferation and cell death was confirmed by viability assays, morphological analysis and cytofluorimetric evaluation of ROS content. The three-dimensional analysis of intracellular uptake of both types of nanoparticles (with different surface charge) was performed by confocal fluorescence microscopy, which showed a main localization in the cytosolic region with no sign of nuclear uptake.

Abstract
A nanostructure formed by the insertion in silica nanoparticles of a pyrene-derivatized cavitand, which is able to specifically recognize ecstasy in water, is presented. The absence of effects from interferents and an efficient electron transfer process occurring after complexation of ecstasy, makes this system an efficient fluorescent probe for this popular drug.

Abstract
One of the biggest challenges in tumour research is the possibility to reprogram cancer
cells towards less aggressive phenotypes. In this study, we reprogrammed primary
Glioblastoma multiforme (GBM)-derived cells towards a more differentiated and less
oncogenic phenotype by activating the Wnt pathway in a hypoxic microenvironment. Hypoxia
usually correlates with malignant behaviours in cancer cells, but it has been recently
involved, together with Wnt signalling, in the differentiation of embryonic and neural
stem cells. Here, we demonstrate that treatment with Wnt ligands, or overexpression of
β-catenin, mediate neuronal differentiation and halt proliferation in
primary GBM cells. An hypoxic environment cooperates with Wnt-induced differentiation, in
line with our finding that hypoxia inducible factor-1α
(HIF-1α) is instrumental and required to sustain the expression of
β-catenin transcriptional partners TCF-1 and LEF-1. In addition, we also
found that Wnt-induced GBM cell differentiation inhibits Notch signalling, and thus gain
of Wnt and loss of Notch cooperate in the activation of a pro-neuronal differentiation
program. Intriguingly, the GBM sub-population enriched of cancer stem cells
(CD133+ fraction) is the primary target of the pro-differentiating
effects mediated by the crosstalk between HIF-1α, Wnt, and Notch
signalling. By using zebrafish transgenics and mutants as model systems to visualize and
manipulate in vivo the Wnt pathway, we confirm that Wnt pathway activation is
able to promote neuronal differentiation and inhibit Notch signalling of primary human GBM
cells also in this in vivo set-up. In conclusion, these findings shed light on an
unsuspected crosstalk between hypoxia, Wnt and Notch signalling in GBM, and suggest the
potential to manipulate these microenvironmental signals to blunt GBM malignancy.

Abstract
Background: Colorectal cancer (CRC) is an important cause of cancer-related death. Prediction of recurrence is an important issue in the treatment of disease, particularly for stage II patients. The level of telomere-specific reverse transcriptase (hTERT), the catalytic component of the telomerase complex, increases along with CRC progression, but its prognostic value is still unclear. Methods: One hundred and thirty-seven CRC patients were studied for hTERT expression in tumour cells by real-time PCR. hTERT level was evaluated as a prognostic factor of overall survival (OS) in all patients and of disease recurrence in a subgroup of 50 stage II patients. Results: The median hTERT level was 93.8 copies (interquartile range 48–254). Patients with high hTERT levels (above the median) showed a significantly worse survival than those with low hTERT levels (below the median; log-rank test P<0.0001; hazard ratio (HR)=3.30 (95% confidence interval (CI) 1.98–5.52); P<0.0001). The negative prognostic value of high hTERT level is independent of the pathological stage and microsatellite instability (HR=2.09 (95% CI 1.20–3.64), P=0.009). Moreover, in stage II CRC, high hTERT levels identified patients with a higher risk of disease recurrence (HR=3.06 (95% CI 1.03–9.04), P=0.043) and death (HR=3.24 (95% CI 1.37–7.71), P=0.008). Conclusion: hTERT level is an independent prognostic marker of OS in CRC patients. In addition, assessment of hTERT level could improve stratification of stage II CRC patients for the risk of disease recurrence.

Abstract
Fluorescence imaging techniques are becoming essential for preclinical investigations, necessitating the development of suitable tools for in vivo measurements. Nanotechnology entered this field to help overcome many of the current technical limitations, and luminescent nanoparticles (NPs) are one of the most promising materials proposed for future diagnostic implementation. NPs also constitute a versatile platform that can allow facile multi-functionalization to perform multimodal imaging or theranostics (simultaneous diagnosis and therapy). In this contribution we have mainly focused on dye doped silica or silica-based NPs conjugated with targeting moieties to enable imaging of specific cancer cells. We also cite and briefly discuss a few non-targeted systems for completeness. We summarize common synthetic approaches to these materials, and then survey the most recent imaging applications of silica-based nanoparticles in cancer. The field of theranostics is particularly important and stimulating, so, even though it is not the central topic of this paper, we have included some significant examples. We conclude with a short section on NP-based systems already in clinical trials and examples of specific applications in childhood tumors. This review aims to describe and discuss, through focused examples, the great potential of these materials in the medical field, with the aim to encourage further research to implement applications, which today are still rare.

Abstract
e13031 It has been suggested that oxygen tension is a crucial component of the brain tumor niche, as hypoxia positively correlates with tumor aggressiveness and over-activity of hypoxia inducible factor-1α (HIF-1α) reinforces tumor progression. Furthermore, hypoxia has been implicated in the regulation of several signaling pathways (Notch, BMP), angiogenesis and importantly, glucose metabolism. Here we investigate the effects mediated by in vitro glycolysis inhibition by using 2-deoxyglucose (2-DG) in glioblastoma (GBM) derived cells maintained under two different oxygen tensions, a lowered oxygen tension (2%) versus a higher non-physiological (20%). GBM account for 50% of all gliomas and arise after age 50 in most patients and it has been seen that younger patients tend to have a better prognosis than the elderly. Our results show that adult GBM displaying a highly immature phenotype manifested the highest resistance to glucose deprivation. Furthermore, increase of multi-drug resistant cell fraction, described as side population, occurred following 2-DG treatment, but only under hypoxia. Neuronal committed precursors were selected by 2-DG, but these effects were mitigated by hypoxia. Also, hypoxia inhibits the mitochondria-controlled apoptosis induced by 2-DG, by conferring cell resistance through progressive activation of pro-survival NF-kB and induction of tumor cell autophagy. Importantly, HIF-1α level reduction and proline hydroxylase 2 (PHD2) upregulation occurred following 2-DG treatment even under hypoxia, and this may depend on reactive oxygen species reduction. These results indicate differences in tumor cells behavior that may be predictive of cell response to therapy aiming to limit glucose uptake or glucose metabolism. No significant financial relationships to disclose.
