Metabolic lactate production coordinates vasculature development and progenitor behavior in the developing mouse neocortex

Project description:Proper neural progenitor behavior in conjunction with orderly vasculature formation is fundamental to the development of the neocortex. However, the mechanisms coordinating neural progenitor behavior and vessel growth remain largely elusive. Here we show that robust metabolic production of lactate by radial glial progenitors (RGPs) co-regulates vascular development and RGP division behavior in the developing mouse neocortex. RGPs undergo a highly organized lineage progression program to produce diverse neural progeny. Systematic single cell metabolic state analysis revealed that RGPs and their progeny exhibit distinct metabolic features associated with specific cell types and lineage progression statuses. Symmetrically dividing, proliferative RGPs preferentially express a cohort of genes that support glucose uptake and anaerobic glycolysis. Consequently, they consume glucose in anaerobic metabolism and produce a high level of lactate, which promotes vessel growth. Moreover, lactate production enhances RGP proliferation by maintaining mitochondrial length. Together, these results suggest that specific metabolic states and metabolites coordinately regulate vasculature formation and progenitor behavior in neocortical development.

Identification of genes regulated by L-lactate and by DL-lactate in Lactobacillus plantarum

Project description:L. plantarum is known to possess an L-lactate inducible lactate racemase activity (Goffin et al. 2005. J. Bacteriol. 187:6750). In the present study, microarrays were used in order to identify all genes that are up-regulated by L-lactate, but not by a racemic mixture of D- and L-lactate. A mutant of L. plantarum NCIMB8826 deficient for NAD-dependent L-lactate activity (TF101; Ferain et al. 1994. 176:596), and thus producing no L-lactate, was grown in MRS medium at 28Â°C until mid-exponential phase (OD600nm 0.75). The culture was then divided into 3 sub-cultures. Optically pure sodium L-lactate (200 mM) was added to the first sub-culture (TF101 + L-lac 200 mM). An equimolar mixture of sodium D- and L-lactate (100 mM each) was added to the second sub-culture (TF101 + L/D-lac 200 mM). The third sub-culture was not treated (TF101; reference sample). The three sub-cultures were further incubated at 28Â°C for 1h30 (a time known to be sufficient for induction of lactate racemase activity by L-lactate). Cells were harvested by centrifugation. Microarray data were used ot identify genes that are specifically induced by L-lactate (comparison of TF101 with TF101 + L-lac 200 mM), but not by DL-lactate (comparison of TF101 with T101 + L/D-lac 200 mM). There are no biological replicates.

Human temporal neocortex brain LC-MS

Project description:We used label-free shotgun mass spectrometry to analyze temporal neocortex samples from AD brain, other neurological disorders and non-demented controls, in order to identify additional proteins thatare altered in AD. The mass spectrometry results were then verified by antibody suspension bead arrays.

Abnormal neocortex arealization and Sotos-like syndrome-associated behavior in Setd2 mutant mice

Project description:Epigenetic regulation of gene expression through histone modifications like methylation of various lysine residues are essential for embryonic development. Here we removed SETD2, a methyltransferase for histone 3 lysine 36 trimethylation (H3K36me3), in the developing dorsal forebrain in mice and show it is required for proper area patterning (arealization) of the neocortex and the formation of thalamo-cortico-thalamic circuits by maintaining the expression of clustered protocadherin (Pcdh) genes in an H3K36me3 methyltransferase-dependent manner. Moreover, the Setd2 mutant mice exhibit defects in social interaction, motor endurance and spatial memory, reminiscent of patients with the Sotos-like syndrome bearing SETD2 mutations.
