Accumulated studies have shown that activation of the Akt pathway plays a pivotal role in malignant transformation and chemoresistance by inducing cell survival, growth, migration, and angiogenesis. Therefore, Akt is believed to be a critical target for cancer intervention. Here, we report the discovery of a small molecule Akt pathway inhibitor, Akt/protein(More)
Recently, a novel class of transcripts, long non-coding RNAs (lncRNAs), is being identified at a rapid pace. These RNAs have critical roles in diverse biological processes, including tumorigenesis. Here we report that taurine-upregulated gene 1 (TUG1), a 7.1-kb lncRNA, recruiting and binding to polycomb repressive complex 2 (PRC2), is generally(More)
Helper virus-free herpes simplex virus (HSV-1) plasmid vectors are attractive for neural gene transfer, but a promoter that supports neuronal-specific, long-term expression is required. Although expression from many promoters is unstable, a 6.8-kb, but not a 766-bp, fragment of the tyrosine hydroxylase (TH) promoter supports long-term expression. Thus, 5'(More)
Autophagy is an evolutionarily conserved 'self-eating' process. Although the genes essential for autophagy (named Atg) have been identified in yeast, the molecular mechanism of how Atg proteins control autophagosome formation in mammalian cells remains to be elucidated. Here, we demonstrate that Bif-1 (also known as Endophilin B1) interacts with Beclin 1(More)
Epileptogenesis, i.e. the process leading to epilepsy with spontaneous recurrent seizures, can be initiated by a number of brain damaging insults, including traumatic brain injury, status epilepticus (SE), and stroke. Such acquired epilepsy is often associated with memory impairment and behavioral problems. There has been a growing interest in the use of(More)
The effects of irradiating blue, UV-A, UV-B and a combination of the lights on anthocyanin accumulation at different hypocotyl positions were investigated in seedlings of the purple top turnip 'Tsuda'. The location of anthocyanin accumulation varied depending on different light spectra. Stronger accumulation of anthocyanin was induced (i) at the upper(More)
Mucolipidosis type IV (MLIV) is a developmental neurodegenerative disorder characterized by severe neurologic and ophthalmologic abnormalities. The MLIV gene, ML4 (MCOLN1), has recently been localized to chromosome 19p13.2-13.3 by genetic linkage. Here we report the cloning of a novel transient receptor potential cation channel gene and show that this gene(More)
BACKGROUND Mucolipidosis type IV (MLIV) is an autosomal recessive disease caused by mutations in the MCOLN1 gene that codes for mucolipin, a member of the transient receptor potential (TRP) gene family. OBJECTIVE To comprehensively characterize the clinical and genetic abnormalities of MLIV. METHODS Twenty-eight patients with MLIV, aged 2 to 25 years,(More)
A microstrip bandpass filter using stepped-impedance resonators is designed in low-temperature co-fired ceramic technology for dual-band applications at 2.4 and 5.2 GHz. New coupling schemes are proposed to replace the normal counterparts. It is found that the new coupling scheme for the interstages can enhance the layout compactness of the bandpass filter;(More)
Two varieties of neurons were found in nucleus parafascicularis (pf) of the rat: one responds to noxious stimuli with an increase in firing (pain-excited neuron, PEN), the other with a decrease in firing (pain-inhibited neuron, PIN). Electroacupuncture (EA) has been shown to suppress PEN and excite PIN, which can be taken as an electrophysiological index(More)
