Накратко на български
Генните мутации и промените в експресията при миди помагат да се разбере причината за развитието на разпространени ракови образувания при тях. Анализът на тези процеси позволява сравнение с механизмите, по които се развива ракът при хората.

Final Activity Report Summary - MIDIA (Molecular indicators of DNA damage in aquatic organisms)
Disseminated neoplasia is a type of cancer that has been reported in mussels from numerous locations worldwide. This condition is progressive and fatal and the precise cause is unknown. In vertebrates such as humans, particular genes play important roles in the development of cancer. Our objectives were to find a number of mussel cancer genes and determine if they were similarly involved in the development of cancer. We have isolated such key genes from mussels that are apparently similar to the human versions. Neoplastic blood samples derived from mussels have been investigated for the presence of gene mutations and changes in gene expression to establish if these may be the cause of this particular cancer in the mussels. Changes in gene expression were found in a particular gene (named ras) but not in another (named p53). No mutations were detected in a preliminary investigation.

Цел на проекта
One of the most important early indicators of pollution in aquatic environments is the effect on indigenous animals, including invertebrates such as mussels. While cellular damage studies have traditionally played an important role, advances in medical techniques now make it possible to study pollution-induced damage at the DNA level, offering an earlier and more sensitive indicator. These techniques have been pioneered in the USA and urgently need development in Europe.Dr Rochelle at Sussex is one of the leading European scientists in this field, building inexperience from working in the aquatic toxicology group at Johns Hopkins University before taking up her current Sussex post. This proposal will bring Corona Coca to Sussex, to work on development of DNA damage studies in invertebrates, building on her research work in Romania. This fellowship will provide the expertise to enable study of pollution in the Romanian Black Sea via DNA damage in mussels. Studies have shown that the chemicals taken up from the marine environment by organisms bind to DNA, leading to tumours in a diverse range of species. Tumours have been described finfish species but less is known regarding DNA damage and tumours in invertebrates. In Europe, invertebrates have yet to be investigated at this molecular level. The fellow\'s PhD studies have shown that European mussels do possess tumours in contaminated areas of the European Black Sea. The fellow will learn and apply state-of-the-art molecular techniques for characterisation of mussel cancer genes and proceed to examine their association with pollution-induced tumours. Throughout the project the fellow will immerse within the European scientific community, establish contacts, raise their academic profile and prepare for a future independent research career.
