Translation of HTT mRNA with expanded CAG repeats is regulated by the MID1-PP2A protein complex.
2012
Expansion of CAG repeats is a common feature of various neurodegenerative disorders, including Huntington's disease. Here we show that expanded CAG repeats bind to a translation regulatory protein complex containing MID1, protein phosphatase 2A and 40S ribosomal S6 kinase. Binding of the MID1-protein phosphatase 2A protein complex increases with CAG repeat size and stimulates translation of the CAG repeat expansion containing messenger RNA in a MID1-, protein phosphatase 2A- and mammalian target of rapamycin-dependent manner. Our data indicate that pathological CAG repeat expansions upregulate protein translation leading to an overproduction of aberrant protein and suggest that the MID1-com…
The E3 Ubiquitin Ligase MID1 Catalyzes Ubiquitination and Cleavage of Fu
2014
Sonic Hedgehog (SHH)-GLI signalling plays an important role during embryogenesis and in tumorigenesis. The survival and growth of several types of cancer depend on autonomously activated SHH-GLI signalling. A protein complex containing the ubiquitin-ligase MID1 and protein phosphatase 2A (PP2A) regulates the nuclear localization and transcriptional activity of GLI3, a transcriptional effector molecule of SHH, in cancer cell lines with autonomously activated SHH signalling. However, the exact molecular mechanisms that mediate the interaction between MID1 and GLI3 remained unknown. Here, we show that MID1 catalyses the ubiquitination and proteasomal cleavage of the GLI3-regulator Fu. Our data…
Isolation and Culture of Oligodendrocytes
2019
Primary cultures of brain-derived rodent cells are widely used to study molecular and cellular mechanisms in neurobiology. In this chapter, we describe methods of purifying and culturing oligodendroglial cells from mouse perinatal brains. In addition, we describe methods of coculturing the purified oligodendrocytes with neurons. When prepared and cultured according to these protocols, many essential aspects of the biology of oligodendrocytes, such as their proliferation, differentiation, and myelination, can be studied in culture.
Consequences of analgesics use in early pregnancy: Results of tests on mice.
2019
International audience; Self-medication during pregnancy continues to be an issue in developing countries due topoor medical education. The most commonly used drugs are analgesics, mainlyacetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of thestudy was to establish whether there are consequences of accidental use of these two drugsduring early embryogenesis. The experimental study was performed on 30 pregnant whitemice, divided into three groups: a first group to which APAP was administered, a secondgroup to which KPF was administered, and group 3 as a control group. At delivery, the babymice were examined, and after their first parturition, they were take…
Effect of seasonality on physico-chemical and microbiological properties of nicastrese milk and artisanal cheese
2021
ABSTRACT Nicastrese is an indigenous Italian goat breed reared in the Calabria region under semi-extensive practices. From January to June, the milk yield of 400 multiparous Nicastrese goats was evaluated. In addition, tank milk and ripened cheese samples were subjected to physico-chemical and microbiological analyses with the aim to assess the effect of the seasonality on quality parameters. The volatile organic compounds profile of the ripened Nicastrese cheese samples was evaluated. Results showed that the seasonality had a significant effect on milk fat, lactose, urea, citric acid contents and acidity. Microbiological analysis of tank milk samples revealed variability among the differen…
Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in‐soil organisms
2017
Abstract Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in‐soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made for specific protection goals for in‐soil organisms being key drivers for relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control and biodiversity. Considering the time‐scales and biological processes related to the dispersal of the majority of in‐soil organisms compared to terrestrial non…
Differentiation among dairy products by combination of fast field cycling NMR relaxometry data and chemometrics
2021
A set of commercial milk and Sicilian cheeses was analysed by a combination of fast field cycling (FFC) nuclear magnetic resonance (NMR) relaxometry and chemometrics. The NMR dispersion (NMRD) curves were successfully analysed with a mathematical model applied on Parmigiano-Reggiano (PR) cheese. Regression parameters were led back to the molecular components of cheeses (water trapped in casein micelles, proteins and fats) and milk samples (water belonging to hydration shells around dispersed colloidal particles of different sizes and bulk water). The application of chemometric analysis on relaxometric data enabled differentiating milk from cheeses and revealing differences within the two sa…

Impiego di un modello predittivo per la microflora del salame S. Angelo in corso di asciugature
2008
The authors carried out a study in order to apply an interspecific competition model to predict the microflora behaviour of S.Angelo IGP salami during the ripening. They consider 3 bacterial population (Lactic Acid Bacteria, Enterobacteria and Listeria monocytogenes – LAB, Ent and Lmo) using the observed curves obtained in a previous work as validation. The model applied setting to 0 all interaction terms does not fit the observed curves while the introduction of 3 interaction terms (betaLmo/LAB = 0.65; betaEnt/LAB = 0.4; betaLmo/Ent = 0.18) produce a good agreement with the observed behaviour of all populations.
Understanding the effect of Vitamin D treatment on human uterine leiomyoma growth using in vitro and in vivo models
2019
Los miomas uterinos afectan al 70% de las mujeres en edad reproductiva, empeorando la calidad de vida de muchas de ellas debido a sus síntomas asociados. A pesar de su alta prevalencia no existe ninguna terapia efectiva para reducir el tamaño de éstos mínimamente invasiva y sin efectos secundarios. Aunque la patogénesis de los miomas no se conoce completamente, la correlación entre el déficit de Vitamina D (Vit D) y el riesgo de miomas uterinos, junto sus efectos antiproliferativos descritos en cáncer, apuntaron a la Vit D como una posible opción terapéutica para tratar los miomas uterinos. En este sentido, la acción de la Vit D ha sido ampliamente estudiada en cáncer, demostrando que su ac…
