• Title: Annotating octopus brain regions: a development of an interactive digital atlas for the cephalopod brain
  SZN Tutor: Graziano Fiorito
  Department: BEOM

Description

A brain atlas is a necessary tool for analyzing structure and function of nervous system in fields of neuroscience and behavioral science. Although various annotations are available for 'brains' of several mammalian and few other species including some invertebrates, annotation for 'brains' of cephalopod mollusks is not available. The proposed thesis work is aimed at filling this gap and implementing a pipeline for construction of a flexible annotation atlas (FAA) of the octopus (O. vulgaris) brain. The workplan include analysis of published works and in-house resources (available at the octopus lab, BEOM Dept, Stazione Zoologica), annotation of serial sections of entire adult octopus’ brain, data on brain structure, digital representation of single areas and ROIs. The produced FAA will be then available as Open Data – implementing FAIR Data Principles – and will help improving the consistency of whole brain ROI definition among laboratories internationally by fulfilling various requests from researchers with its flexibility and reproducibility. The same principles utilized for octopus will be subsequently adopted for other cephalopod species.

• Title: Management of marine litter in deep-sea ecosystems
  Tutor SZN: Frine Cardone
  Department: EMI

Description

Despite deep sea ecosystems are recognized a biodiversity hot spot with relevant functional roles, recent mapping activities have shown that they are largely impacted by marine litter, with important but still underestimated consequences in terms of habitat loss. At present, there are no standardized protocols and best practices able to guide decisions on how and when to deal with this human impact, in terms of removal and restoration techniques. The master thesis will be dedicated to the development of a new framework for the development of standardized methodologies for marine litter removal in cold water habitats. The work will be first dedicated to a systematic review of on-going experiences in this field, this representing the first step for building the new protocol and consequent best practices. Then, a case study where to apply this framework will be selected within the project LIFEDREAMS (https://www.life-dream.eu/) to address framework feasibility. We anticipate that this is a new challenging topic, with wide opportunities to feed the scientific debate.

  Description:

The early stages (eggs, larvae and juveniles) of the fish life cycle have high mortality rates which influence the population dynamics of the adult stages.

• Title: Discovery of the pharmacological potential of marine microalgae against telomerase activity in human cancers

SZN Tutor: Valeria Di Dato
Department: BluBiotech

Description

Telomeres are special sequences located at the ends of chromosomes whose role is to protect the ends of the DNA from damage. However, after each cell division their size decreases and when their length reaches a critical point, the cells undergo apoptosis and/or senescence. Thus, the length of telomeres can act as a biological clock to determine the life span of a cell and an organism, and their length is determined by an enzyme called telomerase. This enzyme is constitutively turned off in somatic cells, while it is highly active in germ cells allowing their continuous replication. Likewise, telomerase is expressed in approximately 90% of cancer cells, thus allowing for their indefinite proliferation. For this reason, telomerase inhibition may represent a preferred specific target for anticancer therapies. Various natural products, commonly derived from plants, have shown telomerase inhibitory activity and include secondary metabolites such as polyphenols, alkaloids, terpenoids, xanthones, and sesquiterpenes.
Marine eukaryotic microalgae are very important components of phytoplankton able to adapt to all kinds of ecological niches and physicochemical conditions due to a series of secondary metabolites they produce. The project aims to identify microalgae species that produce molecules capable of inhibiting telomerase activity in a set of different cancer cell lines for possible exploitation as an anticancer drug.
Approaches used: techniques of biochemistry, molecular and cellular biology, bioinformatics approaches.
Organisms used: diatoms, dinoflagellates.

Conservation of marine Animals and Public Engagement (CAPE):

• Title: Management and databasing of the scientific collections of Stazione Zoologica
  Tutor SZN: Paolo Albano
  Department: CAPE

Description

Stazione Zoologica owns an important historical collection of marine organisms, whose enlargement is undergoing due to the contribution of its scientists and acquisitions from third parties. The internship objective is to learn the techniques to handle samples preserved both in liquids or dry, both historical and modern, both in the public exhibits and preserved uniquely for scientific research. Moreover, the intern will learn about the use of specific software for databasing the collection.

• Title: Patterns and drivers of native species richness decline in the Eastern Mediterranean
  SZN Tutor: Paolo Albano
  Department: CAPE

Description

The Eastern Mediterranean Sea is under the siege of climate warming, biological invasions, and further local stressors. We quantify today's and historical native Mediterranean and non-indigenous species richness with extensive sampling programs and use multidisciplinary approaches at the interface of marine ecology and paleontology to quantify species loss and identify its main drivers. Furthermore, we use functional trait studies and species distribution models to understand and predict the fate of the Mediterranean in future climate scenarios.
