Huntington disease (HD) is an autosomal-dominant neurodegene......
Huntington disease (HD) is an autosomal-dominant neurodegenerative disorder that primarily affects medium spiny striatal neurons (MSN). HD is caused by a CAG repeat expansion in the IT15 gene, which results in a long stretch of polyglutamine close to the amino-terminus of the HD protein huntingtin (Htt). Mutant Htt (mHtt) has effects both in the cytoplasm and in the nucleus. In the cytoplasm, full-length mHtt can interfere with BDNF vesicular transport on microtubules. This mutant protein also may lead to abnormal endocytosis and secretion in neurons, because normal Htt form a complex with the proteins Hip1, clathrin and AP2 that are involved in endocytosis. In addition, mHtt affects Ca2+ signaling by sensitizing InsP3R1 to activation by InsP3, stimulating NR2B/NR1 NMDAR activity, and destabilizing mitochondrial Ca2+ handling. As a result, stimulation of glutamate receptors leads to supranormal Ca2+ responses in HD MSN and mitochondrial Ca2+ overload. The mHtt translocates to the nucleus, where it forms intranuclear inclusions, though they are not primarily responsible for toxicity. Nuclear toxicity is believed to be caused by interference with gene transcription, leading to loss of transcription of neuroprotective molecules such as BDNF. While mHtt binds to p53 and upregulates levels of nuclear p53 as well as p53 transcriptional activity. Augmented p53 mediates mitochondrial dysfunction.More...

Peroxisomes are essential organelles that play a key role in redox signalling and lipid homeostasis. They contribute to many crucial metabolic processes such as fatty acid oxidation, biosynthesis of ether lipids and free radical detoxification. The biogenesis of peroxisomes starts with the early peroxins PEX3, PEX16 and PEX19 and proceeds via several steps. The import of membrane proteins into peroxisomes needs PEX19 for recognition, targeting and insertion via docking at PEX3. Matrix proteins in the cytosol are recognized by peroxisomal targeting signals (PTS) and transported to the docking complex at the peroxisomal membrane. Peroxisomes' deficiencies lead to severe and often fatal inherited peroxisomal disorders (PD). PDs are usually classified in two groups. The first group is disorders of peroxisome biogenesis which include Zellweger syndrome, and the second group is single peroxisomal enzyme deficiencies.More...
Erythropoietin mediated neuroprotection through NF-kB
Erythropoietin (Epo) is most commonly known as the cytokine ......
Erythropoietin (Epo) is most commonly known as the cytokine secreted by the kidneys that stimulates red blood cell production and is used as a drug for the treatment of anemias. Epo is also secreted in the brain in response to hypoxia, such as ischemic stroke. Epo production in the brain is stimulated by the hypoxia-inducible transcription factor HIF-1. Administration of Epo to the brain in rodents before hypoxic stress or other neuronal stresses is neuroprotective, preventing neuronal apoptosis. The erythropoietin receptor (EpoR) is known to associate with JAK kinases that phosphorylate and activate the STAT family of transcription factors. The neuroprotection by Epo involves cross-talk between Epo receptor and anti-apoptotic pathways through activation of NF-kB by the JAK2 kinase. Epo stimulates JAK2 phosphorylation of I-kB, releasing NF-kB to translocate into the nucleus and activate transcription of neuroprotective genes. Neuroprotective genes activated by NF-kB include the anti-oxidant enzyme manganese superoxide dismutase and calbindin-D(28k). The erythropoietin receptor is also essential for proper brain development in mice. The absence of EpoR causes high levels of neuronal apoptosis in the developing mouse brain, further confirming the important role of Epo as a neuroprotective agent.More...
A demonstrated means to increase lifespan in a wide range of......
A demonstrated means to increase lifespan in a wide range of organisms is through the restriction of caloric intake. Reducing the consumption of calories increases the lifespan of many different organisms, including mice. Although caloric restriction has not been demonstrated experimentally to increase human lifespan, short-term changes in physiological measures like insulin responsiveness have been observed. Caloric restriction not only increases lifespan, but decreases age-related deterioration of systems and physiological responses, reducing age related diseases like cancer and neurodegenerative disease. Caloric restriction in animals reduces the levels of plasma glucose and insulin and reduces inflammatory responses and may reduce oxidative stress through reduced oxidative metabolism, further contributing to the health benefits of reduced calorie intake. The reduction in inflammation may be related to reduces plasma glucose and in humans could reduce an inflammation connection to cancer, heart disease, and Alzheimers disease. Genetic analysis has indicated several genes that influence lifespan, particularly those that alter pituitary development, reduce growth hormone secretion, reduce food intake, and reduce apoptosis (p66 Shc). All of these appear to converge on an IGF-1 receptor pathway and to reproduce many of the effects of caloric restriction. Although dwarf mice with defective growth hormone or IGF-1 signaling also have significantly increased lifespan, humans with defects in growth hormone signaling tend to develop diseases that shorten their lifespan. One of the downstream targets of IGF-1 signaling is to repress stress resistance proteins including antioxidant enzymes like superoxide dismutase, and heat shock proteins, so a reduction in IGF signaling may extend lifespan by increasing the expression of stress resistance genes. The link between caloric restriction and IGF signaling may be that a reduction in food intake reduces the expression of IGF-1, increasing the expression of stress resistance proteins. In addition to the IGF-1R mutation, p66 Shc mutation also increases lifespan without significant aberration of other systems. Shc is a target of IGF-1R phosphorylation, and a major inducer of cellular responses to oxidative stress. Shc increases levels of intracellular reactive oxygen species, repressing the forkhead factor FKHRL1. Alhtough FKHRL1 is also involved in apoptosis, in the absence of Shc, FKHRL1 mediates increased resistance to oxidative stress. Exploration of the genes that induce longevity in animals models may enlighten the role of these genes in human disease and lifespan.More...
