PO-182 The upregulation of EPDR1 is related to tumour invasiveness in a cohort of localised colorectal cancer patients
2018
Introduction Colorectal cancer (CRC) represents a relevant public health problem. Despite new therapeutic advances, prognosis of patients diagnosed with advanced disease is still poor. The identification of new markers involved in the mechanisms of invasiveness represents a priority in order to better understand cancer development and generate new therapeutic targets. We describe here the possible role of EPDR1, a gene not yet well characterised, which encodes a protein related to ependymins, a family of piscine transmembrane proteins involved in cell adhesion. To evaluate the role of EPDR1, a translational investigation was planned to explore the consequences of the upregulation of EPDR1 i…
Clinical Approach to Vascular Calcification in Patients With Non-dialysis Dependent Chronic Kidney Disease: Mineral-Bone Disorder-Related Aspects
2021
Chronic kidney disease (CKD) is associated with a very high morbimortality, mainly from cardiovascular origin, and CKD is currently considered in the high- or very high risk- cardiovascular risk category. CKD-mineral and bone disorders (CKD-MBDs), including vascular and/or valvular calcifications, are also associated with these poor outcomes. Vascular calcification (VC) is very prevalent (both intimal and medial), even in non-dialysis dependent patients, with a greater severity and more rapid progression. Simple X-ray based-scores such as Adragão's (AS) are useful prognostic tools and AS (even AS based on hand-X-ray only) may be superior to the classic Kauppila's score when evaluating non-d…
Cellular Uptake of siRNA-Loaded Nanocarriers to Knockdown PD-L1: Strategies to Improve T-cell Functions
2020
T-cells are a type of lymphocyte (a subtype of white blood cells) that play a central role in cell-mediated immunity. Currently, adoptive T-cell immunotherapy is being developed to destroy cancer cells. In this therapy, T-cells are harvested from a patient&rsquo
Espaces du quotidien et dynamiques de l’altérité pendant le confinement
2022
This study is the first result of the research entitled "Mon Espace Vécu" (My Lived Space) conducted in Italy during the first lockdown of 2020 (March-June), which was imposed by the government to contain the Covid-19 pandemic. During that period, the authors collected hundreds of textual testimonies from volunteers experiencing everyday spaces during the pandemic. The reflection, conducted from the perspective of cultural geography and cultural anthropology, develops from the analysis of some of these testimonies. Specifically, this paper focuses on the forms of semantization of space and the relationship between the body, space, and dynamic identity/otherness.
Drosophila DJ-1 mutants are sensitive to oxidative stress and show reduced lifespan and motor deficits.
2007
Parkinson's disease (PD) is a progressive movement disorder caused by the selective and massive loss of dopaminergic neurons (DA) in the substantia nigra pars compacta (SNc). DJ-1 loss-of-function mutations are involved in inherited early-onset PD forms and result in dysfunction of the oxidative stress response. In mice models, DJ-1 loss provokes sensitivity to oxidative insults but does not produce neurodegeneration. Similar results have been found when analyzing Drosophila mutants for the DJ-1 orthologous genes, DJ-1alpha and DJ-1beta. Here, we report the analysis of two new mutations for the Drosophila DJ-1 genes. Both ubiquitous induction of DJ-1alpha knockdown by RNAi and loss of funct…

Persistence of the effects of the covid-19 lockdown on sleep: A longitudinal study
2021
The effects of the COVID-19 pandemic on sleep have been widely documented, but longitudinal evaluations during different phases of the “COVID-19 era” are needed to disentangle the specific consequences of the r145estrictive measures on sleep variables. The aim of this study was to assess the immediate effect of the lockdown’s end on sleep and sleep-related dimensions in an Italian sample, also considering the stress and depressive symptoms. We used an online survey to longitudinally collect data on sociodemographic, environmental, clinical, sleep, and sleep-related variables in two time points: during and immediately after the lockdown. The final sample included 102 participants. The large …
Inhibiting proliferation in KB cancer cells by RNA interference-mediated knockdown of nicotinamide N-methyltransferase expression.
2011
The enzyme Nicotinamide N-methyltransferase (NNMT) catalyzes the methylation of nicotinamide and other pyridines, playing a pivotal role in the biotransformation and detoxification of many drugs and xenobiotic compounds. Several tumours have been associated with abnormal NNMT expression, however its role in tumour development remains largely unknown. In this study we investigated expression levels of Nicotinamide N-methyltransferase in a cancer cell line and we evaluated the effect of shRNA-mediated silencing of NNMT on cell proliferation. Cancer cells were examined for NNMT expression by semiquantitative RT-PCR and Western blot analysis. A HPLC-based catalytic assay was performed to asses…
Social phenotype extended to communities: expanded multilevel social selection analysis reveals fitness consequences of interspecific interactions.
2014
In social species, fitness consequences are associated with both individual and social phenotypes. Social selection analysis has quantified the contribution of conspecific social traits to individual fitness. There has been no attempt, however, to apply a social selection approach to quantify the fitness implications of heterospecific social phenotypes. Here, we propose a novel social selection based approach integrating the role of all social interactions at the community level. We extended multilevel selection analysis by including a term accounting for the group phenotype of heterospecifics. We analyzed nest activity as a model social trait common to two species, the lesser kestrel (Falc…
Air Quality during Covid-19 Lockdown
2021
Air pollution exposure is one of the greatest risks to health worldwide. It is estimated to be responsible for about 4.2 million deaths around the world every year owing to many serious diseases such as heart disease, stroke, acute and chronic respiratory diseases, and lung cancer. The WHO guideline limits are exceeded in several areas around the world, and it is estimated that about 90% of the world’s population is exposed to high air pollution levels, especially in low- and middle-income countries. The COVID-19 pandemic has forced governments to implement severe mobility restriction measures to limit the spread of the virus. This represented a unique opportunity to study the impact of mob…
