Resilience of hop (Humulus lupulus L.) to salinity, heat and drought stresses: A mini-review

2022

Over recent years, the cultivation of hops (Humulus lupulus L.) has spread widely in the Mediterranean, also affecting the southern regions of Spain and Italy with a typical semi-arid climate. Several and recent studies have investigated the responses of this species to the main abiotic stresses, which is an aspect of absolute relevance to the knowledge of the adaptive capacity of hops to the growing conditions of a new cultivation environment. Moreover, given the fact that hops’ phytochemical composition is determined primarily by genetic and environmental factors, and that the species is perennial, the lack of knowledge on the effects of abiotic stress could be reflected in subsequent yea…

Prognostic and Functional Significant of Heat Shock Proteins (HSPs) in Breast Cancer Unveiled by Multi-Omics Approaches

2021

Simple Summary In this study, we investigated the expression pattern and prognostic significance of the heat shock proteins (HSPs) family members in breast cancer (BC) by using several bioinformatics tools and proteomics investigations. Our results demonstrated that, collectively, HSPs were deregulated in BC, acting as both oncogene and onco-suppressor genes. In particular, two different HSP-clusters were significantly associated with a poor or good prognosis. Interestingly, the HSPs deregulation impacted gene expression and miRNAs regulation that, in turn, affected important biological pathways involved in cell cycle, DNA replication, and receptors-mediated signaling. Finally, the proteomi…

Immuno-MALDI-MS in Human Plasma and on-Chip Biomarker Characterizations at the Femtomole Level

2012

Immuno-SPR-MS is the combination of immuno-sensors in biochip format with mass spectrometry. This association of instrumentation allows the detection and the quantification of proteins of interest by SPR and their molecular characterization by additional MS analysis. However, two major bottlenecks must be overcome for a wide diffusion of the SPR-MS analytical platform: (i) To warrant all the potentialities of MS, an enzymatic digestion step must be developed taking into account the spot formats on the biochip and (ii) the biological relevancy of such an analytical solution requires that biosensing must be performed in complex media. In this study, we developed a procedure for the detection …

Towards the standardization of mitochondrial proteomics: the Italian mt-HPP initiative

2017

The mitochondrial Human Proteome Project aims at understanding the function of the mitochondrial proteome and its crosstalk with the proteome of other organelles. Being able to choose a suitable and validated enrichment protocol of functional mitochondria, based on the specific needs of the downstream proteomics analysis, would greatly help the researchers in the field. Mitochondrial fractions from ten model cell lines were prepared using three enrichment protocols and analyzed on seven different LC-MS/MS platforms. All data were processed using neXtProt as reference database. The data are available for the Human Proteome Project purposes through the ProteomeXchange Consortium with the iden…

From microbial proteomics to synthetic biology: Amycolatopsis balhimycina case

2012

Actinomycetes, filamentous Gram-positive bacteria, are usually exploited as bio-farms naturally producing a wide range of small biologically active metabolites, such as antibiotics, extensively used in medicine, food-industry, chemistry and bio-remediation strategies. The development of high throughput technologies, like proteomics, allows functional genomic studies aimed at shedding light on molecular mechanisms controlling the production of useful compounds and macromolecules. Differential proteomic analyses, performed by using Two Dimensional PolyAcrylamide Gel Electrophoresis (2D-PAGE) coupled to mass spectrometry (MS) procedures, revealed novel links between balhimycin production (a va…
