Abstract Mitochondria are important cellular organelles in most metabolic processes and have a highly dynamic nature, undergoing frequent fission and fusion. The dynamic balance between fission and fusion plays critical roles in mitochondrial functions. In recent studies, several large GTPases have been identified as key molecular factors in mitochondrial fission and fusion. Moreover, the posttranslational modifications of these large GTPases, including phosphorylation, ubiquitination and SUMOylation, have been shown to be involved in the regulation of mitochondrial dynamics. Neurons are particularly sensitive and vulnerable to any abnormalities in mitochondrial dynamics, due to their large energy demand and long extended processes. Emerging evidences have thus indicated a strong linkage between mitochondria and neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease and Huntington's disease. In this review, we will describe the regulation of mitochondrial dynamics and its role in neurodegenerative diseases.

Abstract Oxytocin (OT) is one of the neuropituitary hormones and is synthesized in the neurons of the paraventricular nucleus (PVN) and supraoptic nucleus (SON). Previous studies have shown that the mRNAs encoding OT are delivered from the soma to both dendrites and axons of the neurons in the PVN and SON. However, it has not been elucidated whether a translational regulation mechanism to enable local synthesis of the hormone exists in the axons of the neurons of PVN and SON. Elongation factor 2 (EF2) is essential for polypeptide synthesis during protein translation. Moreover, phosphorylation of EF2 by EF2 kinase enhances the translation of certain mRNA species. In the present study, in order to shed light on the mechanisms involved in the translational regulation of OT synthesis, we investigated the localization of phosphorylated EF2. Phospho-EF2 was localized in the soma of the neurons in PVN and SON, and in the swellings of the median eminence where axonal tracts of the neurons in the PVN and SON exist. The phosphorylated form was also observed in the rat hypophysis. Moreover, phospho-EF2 and OT were colocalized in a part of the neurons in the PVN and SON. These results suggest that OT may be partially translated in the axons of neurons in the PVN and SON, and then secreted from the pituitary.

Abstract Intracellular calcium is a powerful secondary messenger that affects a number of calcium sensors, including calpain, a Ca2+-dependent cysteine protease, and calcineurin, a Ca2+/calmodulin-dependent protein phosphatase. Maintenance of low basal levels of intracellular calcium allows for the tightly regulated physiological activation of these proteins, which is crucial to a wide variety of cellular processes, such as fertilization, proliferation, development, learning, and memory. Deregulation of calpain and calcineurin has been implicated in the pathogenesis of several disorders, including hypertension, heart disease, diabetes, cerebral ischemia, and Alzheimer's disease. Recent studies have demonstrated an interplay between calpain and calcineurin, in which calpain can directly regulate calcineurin activity through proteolysis in glutamate-stimulated neurons in culture and in vivo. The calpain-mediated proteolytic cleavage of calcineurin increases phosphatase activity, which promotes caspase-mediated neuronal cell death. Thus, the activation of the calpain-calcineurin pathway could contribute to calcium-dependent disorders, especially those associated with Alzheimer's disease and myocardial hypertrophy. Here, we focus briefly on recent advances in revealing the structural and functional properties of these 2 calcium-activated proteins, as well as on the interplay between the 2, in an effort to understand how calpain-calcineurin signaling may relate to the pathogenesis of calcium- dependent disorders.

Abstract Neuronal apoptosis is involved in neurodegenerative diseases such as Alzheimer's disease and Parkinson.s disease. An efficient means of preventing it remains to be found. Some n-3 polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA, 22 : 6n-3) and eicosapentaenoic acid (EPA, 20 : 5n-3) have been reported to be protective against the neuronal apoptosis and neuronal degeneration seen after spinal cord injury (SCI) [1]. However, it is unclear which kinds of PUFAs have the most potent ability to inhibit neuronal apoptosis and whether the simultaneous treatment of PUFAs inhibits the apoptosis. In the present study, we compared the abilities of various n-3- and n-6- PUFAs to inhibit the apoptosis induced after the administration of different apoptotic inducers, etoposide, okadaic acid, and AraC, in mouse neuroblastoma cells (Neuro2a). Preincubation with DHA (22 : 6n-3), eicosapentaenoic acid (EPA, 20 : 5n-3), alpha-linolenic acid (alpha-LNA, 18 : 3n-3), linoleic acid (LA, 18 : 2n-6), arachidonic acid (AA, 20 : 4n-3), and gamma-linolenic acid (gamma-LNA, 18 : 3n-6) significantly inhibited caspase-3 activity and LDH leakage but simultaneous treatment with the PUFAs had no effect on the apoptosis of Neuro2a cells. There were no significant differences of the anti-apoptotic eff ect among the PUFAs. These results suggest that PUFAs may not be effective for inhibiting neuronal cell death after acute and chronic neurodegenerative disorders. However, dietary supplementation with PUFAs may be beneficial as a potential means to delay the onset of the diseases and/or their rate of progression.

Abstract

2-Mercaptoethanol increases the optical density of assay solutions at wavelengths between 280 to 400 nm, and therefore interferes with the measurement of protein concentration by the microbiuret method. Protein concentration can be determined in the presence of 2-mercaptoethanol up to 6 mM by modification of the method as follows: after the precipitation of protein by trichloroacetic acid in the presence of deoxycholate, the precipitate is resolubilized with NaOH solution. Dithiothreitol interfered with the protein determinations could by made in the presence of 4 mM of dithiothreitol with the modified microbiuret method. This modified method is time-saving and more reliable than other methods for protein determination, such as Lowry's method, in the presence of sulfhydryl reagents.

Abstract

The central nervous system is highly plastic and has been shown to undergo both transient and chronic adaptive changes in response to environmental influences. The purpose of this study was to investigate the effect of hypergravic field on long-term potentiation (LTP) in the mouse hippocampus. Exposure of mice to 4G fields for 48 h had no effect on input-output coupling during extracellular stimulation of Schaffer collaterals and paired pulse facilitation, suggesting that the hypergravic exposure had no detrimental effect on basal neurotransmission in the hippocampus. However, the exposure to 4G fields for 48 h significantly induced LTP compared with the control mouse hippocampus. In contrast, no significant changes of late-phase LTP (L-LTP) were found in the hippocampi of mice exposed to the hypergravic field. Exposure of mice to 4G fields for 48 h enhanced AMPA receptor phosphorylation but not cyclic AMP-responsive element binding protein (CREB) phosphorylation. These results suggest that exposure to hyperdynamic fields influences the synaptic plasticity in the hippocampus.

Abstract

Protein transduction therapy using poly-arginine peptide can deliver the biologically active proteins. A previous study showed that 11 poly-arginine fused p53 protein (11R-p53) effectively penetrated across the plasma membrane and inhibited the proliferation of oral cancer cells. However, the intracellular half-life of the delivered protein was less than 36 h. Previous studies also showed that 2-methoxyestradiol (2-ME), an endogenous non-toxic estrogenic metabolite, induces the stabilization of the wild-type p53 protein in human cancer cells posttranscriptionally. In the present study, we examined whether 2-ME induced the stabilization of 11R-p53 and had an inhibitory effect on the proliferation of oral cancer cells. The application of 2-ME significantly enhanced the inhibitory effect of 11R-p53 on the proliferation of oral cancer cells. However, 2-ME had no effect on the intracellular half-life of 11R-p53 in oral cancer cells. Of interest is the finding that 2-ME suppressed the transcriptional activity of NFkappaB, which has an important role in tumorigenesis, but did not affect p53 transcriptional activity. These results suggest that 2-ME synergistically enhances the 11R-p53-induced inhibition of the proliferation of oral cancer cells through the suppression of NFkB transcription.

Abstract

Cellular stimulating factors on cell proliferation in the supernatants of chick embryo carcases and adult muscles were studied. There were plural stimulating factors in embryonic and adult muscular supernatants that promoted cell proliferation without any supplement of sera and other materials. Salting-out methods with ammonium sulfate, ethanol fractionation, and isoelectric precipitation were used to isolate the stimulating factors, and these three methods proved the presence of plural stimulants on cell proliferation in the supernatants of chick embryo and adult muscles. The stimulants had altered physico-chemical properties and biological activities due to embryological development. The embryonic stimulants enhanced the synthesis of DNA and protein remarkably, and RNA synthesis in whole cell systems slightly. The muscular stimulants enhanced protein synthesis without any stimulation of DNA and RNA synthesis. Partial purification of the stimulants from the ethanol fractions was performed by DEAE-cellulose chromatography and Sephadex gel chromatography.

Abstract

Many studies have shown that a motif of 11 consecutive arginines (11R) is one of the most effective protein transduction domains (PTD) for introducing proteins into the cell membrane. By conjugating this "11R", all sorts of proteins can effectively and harmlessly be transferred into any kind of cell. We therefore examined the transduction efficiency of 11R in cerebral arteries and obtained results showing that 11R fused enhanced green fluorescent protein (11R-EGFP) immediately and effectively penetrated all layers of the rat basilar artery (BA), especially the tunica media. This method provides a revolutionary approach to cerebral arteries and ours is the first study to demonstrate the successful transductionof a PTD fused protein into the cerebral arteries. In this review, we present an outline of our studies and other key studies related to cerebral vasospasm and 11R, problems to be overcome, and predictions regarding future use of the 11R protein transduction method for cerebral vasospasm (CV).

Abstract

Amphiphysin I, known as a major dynamin-binding partner localized on the collars of nascent vesicles, plays a key role in clathrin-mediated endocytosis (CME) of synaptic vesicles. Amphiphysin I mediates the invagination and fission steps of synaptic vesicles by sensing or facilitating membrane curvature and stimulating the GTPase activity of dynamin. Amphiphysin I may form a homodimer by itself or a heterodimer with amphiphysin II in vivo. Both amphiphysin I and II function as multilinker proteins in the clathrin-coated complex. Under normal physiological conditions, the functions of amphiphysin I and some other endocytic proteins are known to be regulated by phosphorylation and dephosphorylation. During hyperexcited conditions, the most recent data showed that amphiphysin I is truncated by the ca2-dependent protease calpain. Overexpression of the truncated form of amphi-physin I inhibited transferrin uptake and synaptic vesicle endocytosis (SVE). This suggests that amphi-physin I may be an important regulator for SVE when massive amounts of Ca2 flow into presynaptic terminals, a phenomenon observed in neurodegenerative disorders such as ischemia/anoxia, epilepsy, stroke, trauma and Alzheimer's disease. This review describes current knowledge regarding the general properties and functions of amphiphysin I as well as the functional regulations such as phosphorylation and proteolysis in nerve terminals.

Abstract

Basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were administered into the rat brain following unilateral fimbria-fornix transection. Both bFGF and NGF stimulated the sprouting of acetylcholinesterase (AChE) positive fibers in the hippocampus on the lesioned side. Furthermore, a small number of AChE-positive fibers were regenerated even when only the vehicle was administered. Rats treated with NGF as well as control group had only thin fibers, whereas those treated with bFGF had not only thin fibers but also thick fibers. These results indicate that intrinsic NGF is released and acts on damaged neurons directly, while bFGF acts them on directly and/or indirectly after brain injury.
