Extracellular Vesicles: Delivery Vehicles of Myokines
2019
Movement and regular physical activity are two important factors that help the human body prevent, reduce and treat different chronic diseases such as obesity, type 2 diabetes, heart diseases, hypertension, sarcopenia, cachexia and cancer. During exercise, several tissues release molecules into the blood stream, and are able to mediate beneficial effects throughout the whole body. In particular, contracting skeletal muscle cells have the capacity to communicate with other organs through the release of humoral factors that play an important role in the mechanisms of adaptation to physical exercise. These muscle-derived factors, today recognized as myokines, act as endocrine and paracrine hor…
Extracellular vesicles in cancer pros and cons: The importance of the evidence-based medicine
2021
In this paper we want to introduce a hot topic for clinical and translational research in oncology and all the related medical fields: the "exosomology", i.e., the science that looks at exosomes as nanovesicular tools for theranostics. Exosomes are extracellular vesicles (EVs) of nanometric sizes actively secreted by normal and, above all, tumor cells. Among the EVs, exosomes are surely the most investigated and with the most promising results, mainly for what concerns their potential as representing the future of the so-called "liquid biopsy". Unfortunately, the huge and increasing amount of data coming from preclinical studies was not followed by an adequate number of clinical investigati…
Chaperonin Hsp60 and Cancer Therapies
2020
The heat shock protein 60 (Hsp60) is a chaperonin belonging to the chaperoning (chaperone) system that typically contributes to protein homeostasis inside mitochondria, but also plays various non-canonical roles unrelated to protein quality control beyond the organelle. Chaperonopathies are disorders in which chaperones play an etiologic-pathogenic role and contribute to the onset/progression of disease. Hsp60 chaperonopathies by mistake are diseases in which the chaperonin is apparently normal (as far as it can be determined with current methodologies) but it actively contributes to pathology, for example in certain types of cancer, and autoimmune and chronic inflammatory disorders. In cer…

La Signora di Bayreuth, il grande inattuale, il ragazzo prodigio: tre scene dalla vita di Richard Strauss
2020
Negli anni in cui s'impone come direttore d'orchestra e compositore il giovane Richard Strauss entra in contatto con Cosima Wagner e Gustav Mahler. In seguito collabora per quasi 25 anni con lo scrittore e drammaturgo Hugo von Hofmannstahl. L'articolo ricostruisce gli sviluppi di tali rapporti attraverso le lettere dei persoanggi coinvolti. In the years in which he established himself as conductor and composer, the Young Richard Strauss came into contact with Cosima Wagner and Gustav Mahler. Afterwards he collaborated for almost 25 years with Hugo von Hofmannstahl. The article reconstructs the developments of these relationships through the letters of the people involved.
Chronic myelogenous leukaemia- derived exosomes mediate autocrine and paracrine interplays within the tumour microenvironment: a role for IL8
2014
La Leucemia Mieloide Cronica (LMC) è una neoplasia ematologica causata dalla traslocazione reciproca t(9:22) con conseguente formazione dell'oncoproteina BCR-ABL con attività tirosin-chinasica costitutiva. L’Imatinib mesilato (IM) è un inibitore selettivo dell’oncoproteina che ha migliorato significativamente la prognosi dei pazienti affetti da LMC. Nonostante il successo terapeutico, un grave problema connesso con la somministrazione di imatinib è lo sviluppo di resistenza farmacologica. E’ quindi necessario lo sviluppo di nuovi agenti antineoplastici che abbiano come target non soltanto le cellule tumorali ma anche il microambiente che le circonda. Recentemente, infatti, l’attenzione dei …

The influence of Span®20 on stratum corneum lipids in Langmuir monolayers: comparison with Azone®
2000
Recently we have proved that Span 20 has the same enhancer effect as Azone on in vitro percutaneous penetration of lipophilic compounds (logP(oct) from 1.34 to 2.33). The purpose of this work is to study the interactions of Span 20 with stratum corneum lipids monolayers and to compare them with Azone. The surface pressure-area characteristics of Span 20 in mixed monolayers with different model lipids (ceramides, cholesterol, free fatty acids and two mixtures of ceramides+cholesterol, and ceramides+cholesterol+free fatty acids) in similar proportions to that which exists in human stratum corneum lipids were recorded as compression isotherms at 25 degrees C. Azone was also investigated on mon…
Role of secondary transporters and phosphotransferase systems in glucose transport by Oenococcus oeni.
2011
ABSTRACT Glucose uptake by the heterofermentative lactic acid bacterium Oenococcus oeni B1 was studied at the physiological and gene expression levels. Glucose- or fructose-grown bacteria catalyzed uptake of [ 14 C]glucose over a pH range from pH 4 to 9, with maxima at pHs 5.5 and 7. Uptake occurred in two-step kinetics in a high- and low-affinity reaction. The high-affinity uptake followed Michaelis-Menten kinetics and required energization. It accumulated the radioactivity of glucose by a factor of 55 within the bacteria. A large portion (about 80%) of the uptake of glucose was inhibited by protonophores and ionophores. Uptake of the glucose at neutral pH was not sensitive to degradation …
