Do you know how animals coordinate the growth of their different organs during development? Systemic signals such as hormones coordinate the development of all organs and direct tissue specific developmental programs.

In our latest article we demonstrate that Drosophila brain development is under the coordination of the hormone ecdysone. We show that neuroblasts have an intrinsic capacity to proliferate indefinitely and require ecdysone signalling to determine cell cycle pace!

In our brand-new article in @PLOSBiology we use Drosophila to show that the transcription and translation of neurotransmitter-associated genes is timely coordinated with the animal’s development.

According to our model, the onset of translation is delayed in order to regulate neuronal maturation. Learn more by checking the link in our bio!

Within hours of #neuron birth, terminal differentiation genes are transcribed, but not translated. In #PLOSBiology, @TheHomemLab reveals that these transcripts are only translated days later in a way that coordinates with developmental stage in #Drosophila plos.io/3IzWad5

These defects are similar to the defects that are observed when neural tube closure defects occur in human fetuses, and sets important foundations to understand how folic acid works during brain formation.

Interestingly, we show that the oncogene dMyc is involved in the upregulation of these transporters, highlighting the important link between oncogenes and metabolic transporters in the regulation of tumor growth.
