The increasing complexity of transcription factors made the evolution of living organisms possible
La ciència està plena de SHEroes que amb la seva passió, treball i creativitat han inspirat la biologia evolutiva d'avui.
Com a part del nostre compromís amb la societat, l'Institut de Biologia Evolutiva (IBE, CSIC-UPF) vol donar crèdit i visibilitat als assoliments de les científiques en evolució.
Amb aquest objectiu, llancem la campanya #WhoisyourSHEro per a compartir històries de dones que han tingut un impacte en la carrera científica dels / les nostres investigadors/es a través de les xarxes socials i la web.
La campanya continua avançant a mesura que més i més dones en evolució inspiren a la comunitat IBE.
Pots unir-te a la conversa a través de les xarxes socials amb l'etiqueta #WhoisyourSHEro.

The increasing complexity of transcription factors made the evolution of living organisms possible
Researchers leaded by the ICREA professor Iñaki Ruiz-Trillo, from Institute of Evolutionay Biology (CSIC-UPF), reveal that increasing complexity of transcription factors is an essential factor in the evolution process of living organisms. Specially concerning the evolution from unicellular to pluricellular organisms. Results of the stuy were published yesterday in the Proceedings of the National Academy of Sciences (PNAS).

The paper analyses the evolution of transcription factors in all eukaryotes. Transcription factors are proteins that bind to DNA and activate or repress gene expression, so they play important roles in animal development. The paper, thus, analyses the evolutionary history of all transcription factors in many eukaryotic genomes. The results show that both animals and plants have the most complex repertoire of transcription factors of all eukaryotic lineages, probably a result of their orchestrated embryonic development. Therefore, the great evolutionary success, the large variety of extant plant and animal forms, was largely due to the acquisition of a complex transcriptional regulation machinery.
