- the present invention generally relates to the field of therapy, prophylaxis and diagnosis of degenerative diseases, in particular neurodegenerative diseases.
- the present invention relates to genes and proteins which are regulated in cells in connection with chronic oxidative stress and which are used for the therapy, prophylaxis and diagnosis of degenerative diseases, in particular neurodegenerative Erlarankungen.
- the present invention further relates to the use of genes and proteins regulated in cells in the context of chronic oxidative stress for the screening of candidate substances to identify prophylactic and / or therapeutic agents which enhance the biological activity of genes and / or proteins modulate in the context of chronic oxidative stress in cells.
- the present invention relates to methods for the diagnosis of degenerative diseases, in particular neurodegenerative diseases, and to methods of identifying prophylactic and / or therapeutic agents which activate the biological activity of genes and / or proteins which are activated in cells in connection with chronic oxidative stress. modulate. Furthermore, the present invention relates to kits for carrying out the diagnostic methods.
- Aerobic organisms use TüTdre ⁇ ⁇ ü ⁇ fechterr ⁇ ältung the entire karTabolen undi ⁇ abolerr metabolism including oxidation reactions to gain energy from the diet and metabolic metabolites available.
- Reactive oxygen species (ROS) and reactive nitrogen species (RNS) such as superoxide anions, hydroxyl radicals, hydrogen peroxide, peroxynitrites, and nitric oxide are continuously produced in the cells.
- ROS reactive oxygen species
- RNS reactive nitrogen species
- the occurrence or emergence of these reactive molecules must be regulated very precisely in order to prevent uncontrolled oxidation or nitration of biomolecules such as proteins, DNA and lipids in the cells.
- Nerve cells are particularly susceptible to oxidative stress because of their high energy consumption and their high metabolic activity.
- the death of nerve cells can have devastating and irreversible effects on the affected person. For example, nerve cell death may occur as a result of stroke, myocardial infarction, traumatic brain and spinal cord injury, infection, inflammatory response, excitotoxicity, ischemia, hypoxia, or other brain or spinal cord deficiency.
- Neurodegenerative diseases such as Morbus (M) Alzheimer's disease, Lewy Body disorders such as Parkinson's disease, diffuse Lewy Body disorders, Huntington's disease, Amyotrophic lateral sclerosis (ALS), Prion-Erlcrankept (PrD) 5 Creutzfeldt- Jakob's disease, Down syndrome, frontotemporal dementia (FTD), corticobasal degeneration, multi-infarct dementia, progressive supranuclear palsy, multisystem atrophy, and Korsakoff's syndrome.
- Dying of nerve cells can also be the result of drug effects. For example, prolonged administration of neuroleptics to treat psychotic conditions in patients may result in chronic tardive dyskinesia caused by the increase in free radical concentration in the affected neurons with subsequent degeneration of the neurons.
- Alzheimer's are characterized by intracellular, predominantly hyperphosphorylated tau protein, neurofibrillary tangles (NFT) and extracellular deposits of amyloid ⁇ (A ⁇ ), j40-42 in_enile_ plaques (SP).
- a ⁇ amyloid ⁇
- SP j40-42 in_enile_ plaques
- the consequence j, sL is a selective loss of cholinergic neurons.
- plaque-free forms of Alzheimer's disease The inherited forms are predominantly caused by mutations in genes encoding A ⁇ precursor protein (APP) and presenilin (PS1 and PS2, respectively).
- APP A ⁇ precursor protein
- PS1 and PS2 presenilin
- Parkinson's disease is caused by dopamine deficiency due to the death of neurons in the substantia nigra of the brain.
- Lewy bodies consist predominantly of aggregated ⁇ -synuclein but also contain other proteins, such as ubiquitin C-terminal hydrolase.
- a familial accumulation of M. Parkinson has been associated with more than 10 chromosomal regions, with mutations in the genes, the ⁇ -synuclein (PARK1), Parkin (PARK2), and DJ-I (PARK7) encode, are clearly l ⁇ ankheitsverursachend.
- ALS is caused by a progressive loss of motor neurons. 20% of familial forms of the disease are associated with more than 90 mutations in Cu-Zn superoxide dismutase (SOD).
- Huntington is caused by the fatal extension of a CAG trinucleotide repeat sequence in the gene encoding Huntington's protein. This extension results in the formation of a glutamine-rich abnormal Huntington protein that accumulates intracellularly and aggregates, and the like. in striatal neurons forms.
- Oxidative stress is therefore critical in the pathogenesis of neurodegenerative diseases
- the active ingredients used fight only symptoms. However, they can not stop the progression of revenue. In part, significant side effects such as dyskinesias, confusion, etc. are triggered.
- the medication aims to replace the missing neurotransmitter or to maximize the function of surviving neurons, the number of which is already drastically high at the onset of symptoms, for example in Alzheimer's disease. by more than 50%, is reduced.
- Inhibitors CEP 13457 and cell replacement therapies (including Spheramine ® ).
- NMDA receptor antagonist riluzole In ALS, the NMDA receptor antagonist riluzole is used for symptomatic therapy. There is a very small increase in the survival time of 2 months, with the disease leading to death within 2-5 years after diagnosis.
- the object of the present invention is to provide genes or their products, which are regulated in the context of chronic oxidative stress in the cells. Furthermore, the object of the present invention is to identify by means of these genes or their products active ingredients for the therapy and / or prophylaxis of degenerative, in particular neurodegenerative diseases.
- Oxygen species can be superoxide anion, hydroxyl radical and H 2 O 2 .
- Nitrogen species can be peroxynitrite and nitric oxide. These species arise, for example, in the reactions of the respiratory chain in the mitochondria of each cell. The risk of cell damage increases if, for example, a high level of metabolic activity prevails in the brain.
- the oxygen species are usually eliminated by antioxidant enzymes such as superoxide dismutase, catalase or glutathione peroxidase. However, if this elimination is not completely successful, hydroxyl radicals form superoxide anions and hydrogen peroxide, which can cause severe cell damage and cell death and, finally, neurological degenerative diseases, for example.
