In this study, we performed immunohistochemistry for somatostatin (SS), neuropeptide Y (NPY), and parvalbumin (PV) in LiCl-pilocarpine-treated rats to observe quantitative changes and axonal sprouting of GABAergic interneurons in the hippocampus, especially in the sclerotic hippocampus. Fluoro-Jade B (FJB) was performed to detect the specific degeneration(More)
Here we found that dual mTORC1/2 inhibitor AZD-2014 significantly inhibited RCC cell survival and growth, with higher efficiency than conventional mTORC1 inhibitors rapamycin and RAD001. RCC cell apoptosis was also induced by AZD-2014. AZD-2014 disrupted mTORC1/2 assembly and activation, while downregulating HIF-1α/2α and cyclin D1 expressions in RCC cells.(More)

A flexible triboelectric nanogenerator (FTENG) based on wavy-structured Kapton film and a serpentine electrode on stretchable substrates is presented. The as-fabricated FTENG is capable of harvesting ambient mechanical energy via both compressive and stretching modes. Moreover, the FTENG can be a bendable power source to work on curved surfaces; it can also(More)
Unregulated cellular proliferation, caused by mutation or dysregulation of growth-promoting proteins, is an underlying cause of cancer. Many such growth-promoting proteins exhibit an increased dependence on the activity of the chaperone heat-shock protein 90 (Hsp90) for correct folding and maturation in the cell. One can therefore envision that inhibition(More)
Mitochondrial dysfunction is implicated in pathogenesis of Parkinson’s disease (PD). Lycopene, a member of the carotenoid family of phytochemicals, exerts its neuroprotective effects by reducing oxidative damage and improving mitochondrial function in several experimental models. In an attempt to clarify the protective effect of lycopene on toxin-insulted(More)
Molecules specifically designed to modulate protein-protein interactions have tremendous potential as novel therapeutic agents. One important anticancer target is the chaperone Hsp90, whose activity is essential for the folding of many oncogenic proteins, including HER2, IGFIR, AKT, RAF-1, and FLT-3. Here we report the design and characterization of new(More)
The use of statistical modeling to test hypotheses concerning the determinants of protein structure requires stability data (e.g., the free energy of denaturation in H(2)O, DeltaG(HOH)) from hundreds of protein mutants. Fluorescence-monitored chemical denaturation provides a convenient method for high-precision, high-throughput DeltaG(HOH) determination.(More)
Hsp90 has emerged as an important anticancer drug target because of its essential role in promoting the folding and maturation of many oncogenic proteins. The authors describe the development of the first high-throughput screen, based on AlphaScreen technology, to identify a novel type of Hsp90 inhibitors that interrupt its interaction with the cochaperone(More)
BACKGROUND AND AIMS Recent studies suggest that cancer stem cells (CSC) may be responsible for tumorigenesis and contribute to some individuals' resistance to cancer therapy. Although research is rapidly advancing in this field, to our knowledge there are few published reports about the CSC in human nasopharyngeal carcinoma (NPC). We undertook this study to(More)
The co-chaperone Hsp70-Hsp90 organizing protein (HOP) plays a central role in protein folding in vivo, binding to both Hsp70 and Hsp90 and bringing them together in a functional complex. Reports in the literature concerning the oligomeric state of HOP have been inconsistent-is it a monomer, dimer, or higher order oligomer? Knowing the oligomeric state of(More)
