Prion diseases are fatal neurodegenerative diseases of the CNS that are associated with the accumulation of misfolded cellular prion protein. There are several different strains of prion disease defined by different patterns of tissue vacuolation in the brain and disease time course, but features of neurodegeneration in these strains have not been(More)
Alpha-synuclein protein is strongly implicated in the pathogenesis Parkinson's disease. Increased expression of α-synuclein due to genetic multiplication or point mutations leads to early onset disease. While α-synuclein is known to modulate membrane vesicle dynamics, it is not clear if this activity is involved in the pathogenic process or if measurable(More)
Neuronatin (Nnat) is an imprinted gene that is expressed exclusively from the paternal allele while the maternal allele is silent and methylated. The Nnat locus exhibits some unique features compared with other imprinted domains. Unlike the majority of imprinted genes, which are organised in clusters and coordinately regulated, Nnat does not appear to be(More)
The tachykinin substance P (SP) is a neuropeptide that is expressed in some nociceptive primary sensory afferents and in discrete populations of spinal cord neurons. Expression of spinal SP and the preprotachykinin-A (PPT-A) gene that encodes SP exhibits plasticity in response to conditions such as peripheral inflammation but the mechanisms that regulate(More)
To study regulation of the preprotachykinin-A gene promoter, we utilised a biolistic gene transfer protocol to deliver a DNA construct that incorporates a portion of the preprotachykinin-A gene promoter and an enhanced green fluorescent protein reporter gene into neonatal rat spinal cord organotypic slices. The ability of the neurokinin-1 receptor agonist(More)
A consensus about the functions of human wild-type or mutated α-synuclein (αSYN) is lacking. Both forms of αSYN are implicated in Parkinson's disease, whereas the wild-type form is implicated in substance abuse. Interactions with other cellular proteins and organelles may meditate its functions. We developed a series of congenic mouse lines containing(More)
No published data exist for normal values of distortion product otoacoustic emissions (DPOAE) in children at primary levels f1 = 65 dB and f2 = 55 dB SPL. These primary levels have been previously demonstrated to be optimal for identification of hearing impaired ears in adults. A total of 102 normal children underwent audiological assessment, including(More)
