Influence of vascular endothelial growth factor variation on human hippocampus morphology.

ABSTRACT:

Background

Morphological abnormalities in hippocampus have been implicated in neuropsychiatric disorders, including depression, schizophrenia, and dementia. Vascular endothelial growth factor (VEGF) has been demonstrated to have neurogenic effects in the hippocampus in rats. However, influence of VEGF variation on hippocampus morphology in humans has yet to be shown. Here, an integrated genetic and neuroimaging approach was used to investigate whether VEGF variation influences hippocampus morphology in humans.

Methods

High-resolution magnetic resonance imaging and voxel-based morphometry were used to identify the influence of genetic variation of VEGFA [rs833068 (SNP-1), rs833070 (SNP-2), rs2146323 (SNP-3) and rs3025020 (SNP-4)] on brain morphology in 47 healthy individuals.
