Ship Clones: Characterization and search for biomarker of marine transmissible cancers

Descripción del proyecto

Mejora de la detección de los cánceres transmisibles por vía marítima

Los cánceres transmisibles se contagian entre individuos a través de la transferencia de células cancerosas vivas. En la naturaleza, tan solo existen tres tipos de cáncer transmisible, que afectan a los perros, los demonios de Tasmania y los moluscos bivalvos marinos. En los dos primeros mamíferos, la transmisión se produce durante el apareamiento, mientras que en los moluscos es posible que las células colonicen nuevos hospedadores a través de las corrientes marinas o la actividad humana. El objetivo del proyecto Ship Clones, financiado por las Acciones Marie Skłodowska-Curie, es estudiar la biología del cáncer transmisible e identificar los biomarcadores relacionados. Dado que el cáncer transmisible constituye un modelo para entender la metástasis del cáncer, los resultados del proyecto trascienden los ecosistemas marinos.

Objetivo

Ship Clones: Characterization and search for biomarker of marine transmissible cancers Clonally transmissible cancers are cell clones that are transmitted between individuals via the transfer of living cancer cells. There are only three known types of naturally occurring clonally transmissible cancers, one of which is a disseminated neoplasia (DN) found in marine bivalves. DN is a leukemia-like cancer characterized by the proliferation of hypertrophied cells. In later stages of the disease, these cells spread throughout all tissues destroying their normal architecture and causing the death of their host organism. A polyphyletic origin of the DN has been detected in the common cockle Cerastoderma edule. DN has appeared on at least six different occasions and the six clones currently known coexist in cockle populations of the European Atlantic coast. In the present proposal high resolution lipidomics and proteomics will be used to screen for clonal biomarkers of DN and help to better understand the biological systems of transmissible cancers. Marine transmissible cancers are interesting biological models to better understand cancer transmissibility and metastasis. Marine clones likely ship using ocean currents to colonize new hosts in different regions. It is likely that they may also be unintentionally introduced by the action of man in disease-free regions. Hence, these cancers represent a potential threat for marine ecosystems, as they negatively impact keystone species (bivalves), that also have important socio-economic value for fisheries. As such, it is paramount to successfully identify, monitor and characterize the prevalence of clonal DN in marine bivalves, before any successful prevention and mitigation actions can be applied.
