Full textRetinitis Pigmentosa (RP) is a genetic disorder characterized by progressive vision loss due to the degeneration of photoreceptors. More than 100 different genes have been linked to RP, and the high genetic heterogeneity hampers the development of treatments to the cure of this disabling disease. A more profound elucidation at the molecular level of the mechanisms underlying the progression of the disease is needed for the development of new therapeutic approaches. This study focused on transcriptional changes during rod photoreceptor degeneration to understand disease mechanisms and find possible therapeutic targets. To gain insights into rod photoreceptor degeneration, we developed a new in vitro model based on the 661W cell line that mimics the PDE6 gene loss of function mutation in RP patients and related animal models. The cell model relies on the treatment of the cell line with zaprinast, a PDE6 inhibitor, and we compared by RNAseq analysis cell exposed to zaprinast versus not treated cells. We successfully identified differentially expressed genes in response to PDE6 inhibition, especially related to cholesterol biosynthesis and metabolism. Several gene changes linked to cholesterol biosynthesis and metabolism have been validated by Real-time qPCR in the cell system. Confirmation of the relevance of the identified genes in retinal degeneration was performed in relevant animal models of RP. In conclusion, the primary degeneration starts in the rod photoreceptors that are post-mitotic neurons. We developed a new in vitro system to mimic rod photoreceptor degeneration, a fundamental tool for future studies enabling molecular studies on cell death mechanisms. Thanks to the new cell system, we analyzed gene expression changes during degeneration. We found that cholesterol biosynthesis and metabolism pathways might have a crucial role in rod photoreceptor loss. Validation of the genes on the animal models shows that the mutations causing RP can trigger an imbalance in cholesterol pathways. We suggest that the cholesterol pathways can be a new target for the development of new therapeutic approaches.

Full textSerum profile, in physiological or pathological conditions, results from the whole effect of both nutritional intake and endogenous metabolism and is commonly used as diagnostic tool. Moreover individual serum components and their concentration are often related to specificity, development and progression of many metabolic diseases. Dietary fat intake strictly affects serum lipid profile and cardiovascular disease epidemiology. Fatty acids derived from diet, both saturated and polyunsaturated fatty acids, have specific and controversial effects. The underlying molecular mechanisms are numerous but partially understood, and they are related to homeostatic metabolic pathways as well gene expression effects. Consequently the aim of this project was to assess the ability of serum samples differing in content of nutritionally related lipid components to specifically affect gene expression of human hepatoma cells (HepG2). We collected 40 human sera, differing in metabolic and nutritionally relevant fatty acids, and tested their effect on hepatoma cells comparing samples from hyperlipidemic (cholesterol average 273 mg/dl) vs normolipidemic male subjects (cholesterol average 155 mg/dl). Analyzed genes were selected among those previously found modulated by lipid nutrients. Determination of fatty acids in sera showed that arachidonic acid (AA) was 88% more abundant in hypercholesterolemic subjects (p<0.01), while docosahexaneoic acid (DHA) and eicosopentanoic acid (EPA), as quota of total detected fatty acids, were significantly higher in normocholesterolemic subjects by 25% (p<0.05) and by 80% (p<0.01) respectively. Normocholesterolemic subjects had an higher n-3/n-6 fatty acids ratio (p<0.05). Hypercholesterolemic sera decreased sterol regulatory element binding protein-1c (SREBP-1c) mRNA by 40% (p<0.05). In hypercholesterolemic group ,UDP-glucuronosyltransferase-1A1 (UGT1A1) mRNA expression was significantly increased by 84% (p<0.01). Samples with higher concentrations of DHA, EPA and AA produced a higher expression of UGT1A1 mRNA. The amount of fatty acids, as c18:2, c18:3, DHA, EPA, AA, is more high in hypercholesterolemic subjects (p<0.01) and has an opposite trend compared to SREBP-1c mRNA expression (p<0.05). Our data clearly indicate that serum lipid profile is functionally linked with gene expression involved in metabolic and nutritional related conditions.[edited by author]

Full textHistone variants play a fundamental role in the complex scenery of epigenetic dynamics and chromatin remodelling; their replication-independent incorporation into chromatin and rapid turnover have recently suggested their involvement in central nervous system (CNS) pathophysiology and plasticity, though their precise role is still to be elucidated. The H3.3 histone variant, highly expressed in the brain, is encoded by two different intron-containing genes namely H3f3a and H3f3b. Although the coded proteins, H3.3A and H3.3B respectively, are identical, knocking out H3f3b generates a more severe phenotype compared to H3f3a, suggesting the lack of a complete functional overlap. This different impact may derive from a differential cell-type expression and regional distribution in the CNS. In order to investigate the functional role of H3.3 variant expression in the CNS it is therefore necessary to clarify the localization and cellular expression of the two isoforms. This will permit to define whether H3.3A and H3.3B turnover, alone or together, participates to molecular mechanisms that lead to neuroplasticity in specific neuronal circuits and associated functions. In this project, hemagglutinin (HA)-tagged H3.3A (WT/HA-fH3.3A) and HA-tagged H3.3B (WT/HA-fH3.3B) mice were used to perform a detailed analysis of H3.3 isoform distribution in CNS white and grey matter regions, by using semi-quantitative immunohistochemistry (IHC). Moreover, cell-specific expression of these proteins was assessed by using specific antibodies against microglia, astrocytes, oligodendrocytes and neurons through double immunofluorescent (IF) stainings and high-resolution confocal microscopy. H3.3A and H3.3B have a widespread though different region-specific distribution and, as concerns their cellular expression, they are mostly, though not exclusively, expressed by neurons. Innovative techniques such as tissue clearing and lightsheet microscopy allowed us to obtain an overall view of H3.3 isoform distribution in the whole brain. Finally, we investigated the possible changes in H3.3 expression in various physiological conditions, including ageing and exposure to an enriched environment, a procedure that models the neurotrophic and neuroprotective impact of high educational attainment in humans. In this latter model, an increased expression of H3.3B variant in specific brain areas and cell types was observed. Our results demonstrate for the first time a different regional distribution and cellular expression of the two H3.3 isoforms in the mouse CNS as well as their changes in various physiological conditions. This opens up a path to the generation of cell-population specific conditional knock-out mice to elucidate H3.3 isoform contribution to the function of precise cerebral circuits.
