Transcription profiling of mouse FACS-purified cortical projection neurons using Affymetrix 430 2.0 microarrays

Project description:3 subtypes of cortical projection neurons were purified by fluorescence-activated cell sorting (FACS) at 4 different stages of development from mouse cortex. A detailed description of the data set is described in Arlotta, P et al (2005) and Molyneaux, BJ et al (2009). The hybridization cocktails used here were originally applied to the Affymetrix mouse 430A arrays and submitted as GEO accession number GSE2039. The same hybridization cocktails were then applied to the Affymetrix mouse 430 2.0 arrays, and those data are contained in this series. Experiment Overall Design: Three subtypes of cortical neurons were purified by FACS at multiple stages of mouse brain development. The neuron subtypes are: corticospinal motor neurons (CSMN), callosal projection neurons (CPN), and corticotectal projection neurons (CTPN). The stages of development included embryonic day 18 (E18), postnatal day 3 (P3), postnatal day 6 (P6), and postnatal day 14 (P14). CSMN and CPN were analyzed at all four stages, while CTPN were only analyzed at P14. The replicates included in the data set are all true biological replicates with independent sample collection for each.

RNA sequencing of corticospinal neurons and control callosal projection neurons purified from the cerebral cortex of adult wild-type and Sod1G86R mice, a model of amyotrophic lateral sclerosis, at four disease-relevant ages.

Project description:Amyotrophic Lateral Sclerosis is clinically defined as the combined degeneration of the corticospinal and corticobulbar neurons (CSN) along with the bulbar and spinal motor neurons (SMN). While a growing body of evidence points to the motor cortex, where CSN are located, as the potential initiation site of ALS, little is known about how CSN degenerate. To gain insights into the molecular mechanisms behind CSN selective degeneration, we first developed an approach to purify this neuronal population from the cerebral cortex of adult wild-type and Sod1G86R mice, combining retrograde labelling and Fluorescence Activated Cell Sorting. In parallel, a second population of cortical neurons, the callosal projection neurons (CPN) located in the layers II/III of the cerebral cortex were also purified. CPN and CSN are both cortical excitatory projection neurons but as opposed to CSN, CPN do not degenerate in Sod1G86R mice, and served as control population. CSN and CPN were purified from same animals, at two presymptomatic ages (3 and 60 days) and two symptomatic ages, 90 and 105 days. A total of 57 samples were further processed and analysed (CSN: 30d: n=4 WT and 3 Sod1G86R; 60d: n=4 WT and 4 Sod1G86R; 90d: n=4 WT and 4 Sod1G86R; 105d: n=4 WT and 2 Sod1G86R; CPN: 30d: n=4 WT and 3 Sod1G86R; 60d: n=2 WT and 3 Sod1G86R; 90d: n=4 WT and 4 Sod1G86R; 105d: n=4 WT and 4 Sod1G86R).

Identification of molecular controls over corticospinal motor neuron segmental target specificity

Project description:Molecular mechanisms over differentiation and differential axonal targeting of distinct neuron subtypes in the cerebral cortex are beginning to be elucidated. These studies have focused on controls that specifically distinguish one subtype of neocortical projection neurons, e.g. corticospinal motor neurons (CSMN), from closely related corticothalamic projection neurons (CThPN) or intracortical callosal projection neurons (CPN). CSMN are located in layer V of the neocortex and make synaptic connections to motor output circuitry in the spinal cord and brainstem. CSMN axons form the corticospinal tract (CST), which is the major motor output pathway from the motor cortex and critically controls voluntary movement. CSMN somatotopically and precisely target specific segments along the rostrocaudal axis of the spinal cord, the molecular basis for which remains unknown. We used microarrays to examine gene expression differences between two CSMN subpopulations that target different levels of the spinal cord - CSMN-C (which extend axons to the brainstem and cervical spinal cord) and CSMN-L (which preferrrentially extend axons to the thoracic and lumbar spinal cord). We compared CSMN-C vs CSMN-L gene expression at 3 critical developmental time points (previously described in Arlotta et a., 2005)

Identification of molecular controls of Corticothalamic projection neurons differentiatiion

Project description:Molecular mechanisms controlling specification and differentiation of distinct neuron subtypes in the cerebral cortex are not well understood. Corticothalamic projection neurons (CThPN) are a diverse set of neurons, critical for function of the neocortex, but little is known about the molecular mechansims controlling their development. We used microarrays to detail CThPN gene expression at 3 developmental time points. We then compared CThPN gene expression, with the gene expression of other neuron subtypes in the cerebral cortex at the same stages (previously described in Arlotta et a., 2005)
