[HTML][HTML] Involvement of caspases in proteolytic cleavage of Alzheimer's amyloid-β precursor protein and amyloidogenic Aβ peptide formation

FG Gervais, D Xu, GS Robertson, JP Vaillancourt… - Cell, 1999 - cell.com
The amyloid-β precursor protein (APP) is directly and efficiently cleaved by caspases during
apoptosis, resulting in elevated amyloid-β (Aβ) peptide formation. The predominant site of …

Bax-dependent caspase-3 activation is a key determinant in p53-induced apoptosis in neurons

…, JG MacLaurin, CG Craig, GS Robertson… - Journal of …, 1999 - Soc Neuroscience
p53 is a pivotal molecule regulating the death of neurons both after acute injury and during
development. The molecular mechanisms by which p53 induces apoptosis in neuronal cells, …

Evidence for conditional neuronal activation following exposure to a cocaine-paired environment: role of forebrain limbic structures

EE Brown, GS Robertson, HC Fibiger - Journal of Neuroscience, 1992 - Soc Neuroscience
The reinforcing properties of cocaine can readily become associated with salient environmental
stimuli that acquire secondary reinforcing properties. This form of classical conditioning …

Inhibition of calpains prevents neuronal and behavioral deficits in an MPTP mouse model of Parkinson's disease

…, E Melloni, S Przedborski, GS Robertson… - Journal of …, 2003 - Soc Neuroscience
The molecular mechanisms mediating degeneration of midbrain dopamine neurons in
Parkinson's disease (PD) are poorly understood. Here, we provide evidence to support a role for …

Neuroprotection by the inhibition of apoptosis

GS Robertson, SJ Crocker, DW Nicholson… - Brain …, 2000 - Wiley Online Library
Accumulating evidence strongly suggests that apoptosis contributes to neuronal cell death
in a variety of neurodegenerative contexts. Activation of the cysteine protease caspase‐3 …

Suppression of Rho-kinase activity promotes axonal growth on inhibitory CNS substrates

…, GW Hiebert, L Oschipok, GS Robertson… - Molecular and Cellular …, 2003 - Elsevier
Several molecules inhibit axonal growth cones and may account for the failure of central
nervous system regeneration, including myelin proteins and various chondroitan sulfate …

Induction patterns of Fos-like immunoreactivity in the forebrain as predictors of atypical antipsychotic activity.

GS Robertson, H Matsumura, HC Fibiger - Journal of Pharmacology and …, 1994 - ASPET
Clozapine and haloperidol produce different induction patterns of c-fos expression in the
forebrain, with haloperidol increasing Fos-like immunoreactivity (FLI) in the striatum, nucleus …

[HTML][HTML] Selective, reversible caspase-3 inhibitor is neuroprotective and reveals distinct pathways of cell death after neonatal hypoxic-ischemic brain injury

…, J Colucci, R Siman, A Giroux, GS Robertson… - Journal of Biological …, 2002 - ASBMB
Hypoxia-ischemia (HI) in the developing brain results in brain injury with prominent features
of both apoptosis and necrosis. A peptide-based pan-caspase inhibitor is neuroprotective …

Elevated ATG5 expression in autoimmune demyelination and multiple sclerosis

…, V Bhan, WB Kiosses, JL Whitton, GS Robertson… - Autophagy, 2009 - Taylor & Francis
Multiple sclerosis (MS) is an inflammatory central nervous system (CNS) disorder characterized
by T cell mediated demyelination. In MS, prolonged T cell survival and increased T cell …

[HTML][HTML] E2F1 mediates death of B-amyloid-treated cortical neurons in a manner independent of p53 and dependent on Bax and caspase 3

…, ST Hou, M O'Hare, N Dyson, GS Robertson… - Journal of Biological …, 2000 - ASBMB
Although B-amyloid (AB) is suggested to play an important role in Alzheimer's disease, the
mechanisms that control AB-evoked toxicity are unclear. We demonstrated previously that the …
