Abstract Flavonols are important ultraviolet light protectants in many plants and contribute substantially to the quality health-promoting effects of fruits derived plant products. To study regulation flavonol synthesis fruit, we isolated characterized grapevine (Vitis vinifera ‘Shiraz’) R2R3-MYB transcription factor VvMYBF1. Transient reporter assays established VvMYBF1 be a specific activator synthase1 (VvFLS1) several other promoters Arabidopsis (Arabidopsis thaliana) genes involved...
Plant stilbenes are phytoalexins that accumulate in a small number of plant species, including grapevine (Vitis vinifera), response to biotic and abiotic stresses have been implicated many beneficial effects on human health. In particular, resveratrol, the basic unit all other complex stilbenes, has received widespread attention because its cardio-protective, anticarcinogenic, antioxidant properties. Although stilbene synthases (STSs), key enzymes responsible for resveratrol biosynthesis,...
Although mutated HLA ligands are considered ideal cancer-specific immunotherapy targets, evidence for their presentation is lacking in hepatocellular carcinomas (HCCs). Employing a unique multi-omics approach comprising neoepitope identification pipeline, we assessed exome-derived mutations naturally presented as class I HCCs.
Grapevine (Vitis vinifera L.) is a species well known for its adaptation to radiation. However, photomorphogenic factors related UV-B responses have not been molecularly characterized. We cloned and studied the role of RECEPTOR (UVR1), ELONGATED HYPOCOTYL 5 (HY5), HY5 HOMOLOGUE (HYH) from V. vinifera. performed gene functional characterizations, generated co-expression networks, tested them in different environmental conditions. These genes complemented Arabidopsis uvr8 hy5 mutants...

The roles other coinhibitory molecules and their individual contributions to T‐cell dysfunction liver cancer, however, remain largely elusive. APPROACH RESULTS We performed a comprehensive mRNA profiling cluster differentiation 8 (CD8) T cells murine model autochthonous cancer by...
In grapevine, flavonoids constitute one of the most abundant subgroups secondary metabolites, influencing quality, health value, and typicity wines. Their synthesis in many plant species is mainly regulated at transcriptional level by modulation flavonoid pathway genes either single regulators or complexes different regulators. particular, bZIP MYB factors interact synergistically recognition light response units present promoter some pathway, thus mediating light-dependent biosynthesis. We...
Some pathogenic species of the Botryosphaeriaceae have a latent phase, colonizing woody tissues while perennial hosts show no apparent symptoms until conditions for disease development become favorable. Detection these pathogens is often limited to later phase. The phase poorly characterized, despite need non-destructive detection tools and effective quarantine strategies, which would benefit from identification host-based markers in leaves. Neofusicoccum parvum infects wood grapevines other...
European grapevine cultivars (Vitis vinifera spp.) are highly susceptible to the downy mildew pathogen Plasmopara viticola. Breeding of resistant V. is a promising strategy reduce impact disease management. Most that have been bred for resistance mildew, rely on mediated by Rpv3 (Resistance P. viticola) locus. However, despite extensive use this locus, little known about mechanism Rpv3-mediated resistance.In study, defense responses were investigated in Rpv3+ and Rpv3- following inoculation...
Flavonols constitute a group of flavonoids with important photoprotective roles in plants. In addition, flavonol content and composition greatly influences fruit quality. We previously demonstrated that the grapevine R2R3-MYB transcription factor (TF) VviMYBF1 promotes accumulation by inducing expression synthase (VviFLS1/VviFLS4), key step initial pathway. Despite this, gene networks underlying modification including both structural regulatory genes remain poorly understood. order to...
Background and aims Besides well-defined genetic alterations, the dedifferentiation of mature acinar cells is an important prerequisite for pancreatic carcinogenesis. Acinar-specific genes controlling cell homeostasis are extensively downregulated during cancer development; however, underlying mechanisms poorly understood. Now, we devised a novel in vitro strategy to determine genome-wide dynamics epigenetic landscape Design With our carcinogenic sequence, performed global gene expression...
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease mainly affecting upper and lower motoneurons. Several functionally heterogeneous genes have been associated with the familial form of this disorder (fALS), depicting an extremely complex pathogenic landscape. This heterogeneity has limited identification effective therapy, bleak prognosis will only improve greater understanding convergent mechanisms. Recent evidence from human post-mortem material diverse model systems...
