  2. 1. Expression and functional analysis of the SCA7 disease protein ataxin-7

    Author : Anna-Lena Ström; Monica Holmberg; Patrik Brundin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Polyglutamine disease; CAG repeat; Spinocerebellar ataxia type 7; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Spinocerebellar ataxia type 7 (SCA7) is a neurodegenerative disease characterized by cerebellar ataxia and visual problems due to a progressive and selective loss of neurons within the cerebellum, brainstem and retina. The disease is caused by the expansion of a CAG repeat in the first coding exon of the SCA7 gene, resulting in an expanded polyglutamine domain in the N-terminal part of ataxin-7, a protein of unknown function.

  4. 2. Molecular mechanism(s) underlying neurodegeneration in SCA7 disease : Role of NOX enzymes and oxidative stress

    Author : Abiodun Ajayi; Anna-Lena Ström; Ana Cristina Rego; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurodegeneration; oxidative stress; NOX; metabolism; p53; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Spinocerebellar ataxia type 7 (SCA7) is an autosomal dominant neurodegenerative disorder caused by a CAG trinucleotide expansion in the SCA7 gene resulting in progressive ataxia and retinal dystrophy. SCA7 belongs to a group of neurodegenerative disorders called polyglutamine (polyQ) diseases, that share the common feature of glutamine tract expansions within otherwise unrelated proteins.

  5. 3. Study of molecular mechanism(s) underlying neurodegeneration in SCA7 disease : Role of NOX enzymes and oxidative stress

    Author : Abiodun Ajayi; Anna-Lena Ström; Boris Zhivotosky; Bengt Mannervik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurodegeneration; polyglutamine; oxidative stress; metabolism; NADPH oxidase; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Spinocerebellar ataxia type 7 (SCA7) is an autosomal dominant neurodegenerative disorder caused by a CAG trinucleotide expansion in the SCA7/ATXN7 gene resulting in progressive ataxia and retinal dystrophy. SCA7 belongs to a group of neurodegenerative disorders called polyglutamine (polyQ) diseases, that share the common feature of glutamine tract expansions within otherwise unrelated proteins.

  6. 4. PepFect14, a Versatile Cell-Penetrating Peptide

    Author : Maxime Gestin; Ülo Langel; Anna-Lena Ström; Angelita Rebollo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-Penetrating Peptides; PepFect14; transfection; signaling mechanisms; intracellular targeting; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Cell-penetrating peptides have been discovered almost three decades ago and there are, nowadays, thousands of available sequences. They offer multiple applications in the field of drug delivery as they are able to carry therapeutic macromolecules across the plasma membrane. READ MORE

  7. 5. Characterization of Diagnostic Tools and Potential Treatments for Alzheimer’s Disease : PET ligands and BACE1 inhibitors

    Author : Fredrik Jeppsson; Anna-Lena Ström; Kerstin Iverfeldt; Samuel Svensson; Martin Hallbeck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alzheimer’s disease; Diagnostics; Treatment; PET ligand; BACE1; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Alzheimer’s disease (AD) is a very complex disorder and the most common form of dementia. The two pathological hallmarks of AD are extracellular amyloid-β (Aβ) plaques in cerebral cortex, and intraneuronal neurofibrillary tangles. READ MORE
