In studies conducted on the fruit fly, researchers at IRB Barcelona headed by ICREA Professor Marco Milan have revealed that organs have the molecular mechanisms to control their proportions. In this process the protein p53 plays a crucial role. The study is published in the prestigious journal PLoS Biology. The correct establishment of organ proportions, which occurs during embryonic development, is vital for the proper function of all organisms. Alterations in the mechanisms responsible for these processes cause fatal errors in embryos and even cause their death...
