Project

Identify new candidate genes involved in brain size regulation and microcephaly

An increase in brain size and complexity was crucial during the human evolution, helping ancestors to develop survival strategies during the movement of populations from one continent to another. While between H. neanderthalensis and H. sapiens, brain size was mildly reduced, complexity was increased. The fully sequenced Neanderthal genome has become a powerful tool for dissecting the evolutionary changes that defined the development of the more complex brain of modern humans. Recent studies revealed that 31,389 new single-nucleotide changes became fixed in the H. sapiens genome, compared to ancestral Denisovans and Neanderthals. Among these nucleotide substitutions, 3,117 occur in regulatory regions, 32 in putative splice sites and 96 in the coding regions of around 40 proteins. Supporting the possibility that some of these mutations affect brain development, a number of these proteins are expressed in the ventricular zone, where neurons of the cerebral cortex are formed during fetal development, or have proposed roles at centrosomes or in mitotic spindle assembly. In addition, mutations in several of these genes have been directly linked to human neurodevelopmental disorders, such as microcephaly or lissencephaly.

During my postdoc I’ll focus on the phenotypic screening of some of the 40 genes carrying fixed changes between the Neanderthal and H. sapiens genomes in order to identify new genes involved in brain size regulation that could represent microcephaly candidate genes and to define their molecular functions. We will look for typical features that we can find in microcephaly and understand the molecular and cellular mechanisms that can lead to a disease. In particular, we will focus on the DNA damage, cell cycle arrest and centrosome structure and functionality. Since many microcephalic genes are also involved in the cilia structure and functions we will investigate ciliogenesis in our cellular model.
