Gut microbiota has a proven role in regulating multiple neuro-chemical pathways through the highly interconnected gut-brain axis. Oral bacteriotherapy thus potential treatment of central nervous system-related pathologies, such as Alzheimer's disease (AD). Current AD treatments aim to prevent onset, delay progression and ameliorate symptoms. In this work, 3xTg-AD mice early stage were treated with SLAB51 probiotic formulation, thereby affecting composition gut its metabolites. This...
The gut-brain axis is a bidirectional communication network functionally linking the gut and central nervous system (CNS). Based on this, rational manipulation of intestinal microbiota represents novel attractive therapeutic strategy for treatment CNS-associated disorders. In this study, we explored properties probiotic formulation (namely SLAB51) in counteracting brain oxidative damages associated with Alzheimer's disease (AD). Specifically, transgenic AD mice (3xTg-AD) were treated SLAB51...
Cerebral glucose homeostasis deregulation has a role in the pathogenesis and progression of Alzheimer's disease (AD). Current therapies delay symptoms without definitively curing AD. We have previously shown that probiotics counteract AD 3xTg-AD mice modifying gut microbiota inducing energy metabolism glycolysis-gluconeogenesis. Ameliorated cognition is based on higher neuroprotective hormones concentrations, reduced amyloid-β burden, restored proteolytic pathways. Here, we demonstrate oral...
Background: Insufficient sleep is a serious public health problem in modern society. It leads to increased risk of chronic diseases, and it has been frequently associated with cellular oxidative damage widespread low-grade inflammation. Probiotics have attracting increasing interest recently for their antioxidant anti-inflammatory properties. Here, we tested the ability probiotics contrast stress inflammation induced by loss. Methods: We administered multi-strain probiotic formulation...
A series of ruthenium(II) arene complexes with the 4-(biphenyl-4-carbonyl)-3-methyl-1-phenyl-5-pyrazolonate ligand, and related 1,3,5-triaza-7-phosphaadamantane (PTA) derivatives, has been synthesized. The compounds have characterized by NMR IR spectroscopy, ESI mass spectrometry, elemental analysis, X-ray crystallography. Antiproliferative activity in four human cancer cell lines was determined MTT assay, yielding dose- line-dependent IC50 values 9-34 μM for three...
Gut microbiota has emerged as an important key regulator of health and disease status. Indeed, gut microbial dysbiosis been identified in increasing number diseases, including neurodegenerative disorders. Accordingly, alterations have reported also Alzheimer's (AD), suggesting possible pathogenetic mechanisms contributing to the development specific AD hallmarks exacerbating metabolic neuroinflammation. The identification these is crucial develop novel, targeted therapies identify potential...
Tyrosine kinase inhibitors (TKI) such as sunitinib and pazopanib display their efficacy in a variety of solid tumours. However, use therapy is limited by the lack evidence about ability to induce cell death cancer cells. Our aim was evaluate cytotoxic effects induced 5637 J82 bladder lines.Cell viability tested MTT assay. Autophagy evaluated western blot using anti-LC3 anti-p62 antibodies, acridine orange staining FACS analysis. Oxygen radical generation necrosis were determined analysis...
Abstract Organometallic ruthenium(II) complexes of general formula [(η 6 ‐arene)Ru(curcuminato)Cl], with arene being p ‐ i PrC H 4 Me ( 1 ), C 2 and 3 were synthesized, characterized, evaluated for their antitumor effects. Specifically, we explored ability to regulate the proteasome, a validated pharmacological target in cancer treatment. Ruthenium inhibited isolated proteasomes various extents, biological activity these depending on nature bound arene; particular, ‐arene)Ru(curcuminato)Cl]...

Cancer cells require both energy and material to survive duplicate in a competitive environment. Nutrients, such as amino acids (AAs), are not only caloric source, but can also modulate cell metabolism modify hormone homeostasis. Our hypothesis is that the environmental messages provided by AAs rule dynamics of cancer life or death, alteration balance between essential (EAAs) non-essential (NEAAs) (lower higher than 50%, respectively) present nutrients may represent key instrument alter...
Alzheimer’s disease is a neurodegeneration with protein deposits, altered proteolysis, and inflammatory oxidative processes as major hallmarks. Despite the continuous search for potential therapeutic treatments, no cure available to date. The use of natural molecules adjuvants in treatment very promising strategy. In this regard, ginsenosides from ginseng root show variety biological effects. Here, we dissected role Rg1 Rg2 modulating autophagy stress neuroblastoma cells overexpressing...
Alzheimer's disease (AD) is a progressive neurodegeneration characterized by neuron death ending in memory and cognitive decline.A major concern AD research the identification of new therapeutics that could prevent or delay onset disorder, with current treatments being effective only reducing symptoms.In this perspective, use engineered probiotics as therapeutic tools for delivery molecules to eukaryotic cells finding application several disorders.This work introduces strategy treatment...
Alzheimer's disease (AD) is a progressive neurodegeneration characterized by extensive protein aggregation and deposition in the brain, associated with defective proteasomal autophagic-lysosomal proteolytic pathways. Since current drugs can only reduce specific symptoms, identification of novel treatments major concern AD research. Among natural compounds, (poly)phenols their derivatives/metabolites are emerging as candidates prevention due to multiple beneficial effects. This study aims...
Abstract Alzheimer’s disease (AD) is a progressive neurodegeneration with dysfunctions in both the ubiquitin–proteasome system (UPS) and autophagy. Astroglia participation AD an attractive topic of research, but molecular patterns are partially defined available vitro models have technical limitations. Immortalized astrocytes from hippocampus 3xTg-AD wild-type mice (3Tg-iAstro WT-iAstro, respectively) been obtained as attempt to overcome primary cell line limitations this study aims at...
Thymoquinone, a naturally derived agent, has been shown to possess antioxidant, antiproliferative and proapoptotic activities. In the present study, we explored thymoquinone effects on proteasomal complex, major system involved in removal of damaged, oxidized misfolded proteins. purified 20S complexes, subunit-dependent composition-dependent inhibition was observed, chymotrypsin-like trypsin-like activities were most susceptible treatment.
