The aggregation of proteins with expanded polyglutamine (polyQ) tracts is directly relevant to the formation of neuronal intranuclear inclusions in Huntington's disease. In vitro studies have uncovered the effects of flanking sequences as modulators of the driving forces and mechanisms of polyQ aggregation in sequence segments associated with HD. Specifically, a seventeen-residue amphipathic st...
The Rho family members Cdc42, Rac, and Rho play a central role in the organization of the actin cytoskeleton and regulate transcription. Whereas Rac and Rho have been implicated in transformation by oncogenic Ras, the role of Cdc42 in this process remains unknown. In this study, we found that Rat1 fibroblasts expressing constitutively active V12-Cdc42 were anchorage independent and proliferated...
A Schiff base based tripodal receptor was synthesized and complexed with a zinc metal ion (n17) using a very easy single step process. The resulting complex was fully characterized by CHN and single crystal XRD. The real time application of the complex in aqueous media was devised by preparing its organic nanoparticles (ONPs) and their sensor activity was tested with various anions by observing...
Huntington's disease is a neurodegenerative disorder associated with the expansion of the polyglutamine tract in the exon-1 domain of the huntingtin protein (htte1). Above a threshold of 37 glutamine residues, htte1 starts to aggregate in a nucleation-dependent manner. A 17-residue N-terminal fragment of htte1 (N17) has been suggested to play a crucial role in modulating the aggregation propens...
Aflatoxin B1 (AFB1), one of the most potent naturally occurring mutagens and carcinogens, causes significant threats to the food industry and animal production. In this study, 25 bacteria isolates were collected from grain kernels and soils displaying AFB1 reduction activity. Based on its degradation effectiveness, isolate N17-1 was selected for further characterization and identified as Pseudo...
Present: Due to an error made during the assembly of Figure 6A, the same image panel was inadvertently used for both the RhoA-V14+met (Column 4, Row 1) and Rac1-N17+met (Column 2, Row 2). FIGURE 6: Rho GTPase inhibitors attenuate metformin effects on the survival of neuroblastoma cells. (A) Fluorescence images showing the signals of GFP-Rac1, GFP-Cdc42 and GFP-RhoA in SH-SY5Y cells. Cells were ...
Huntington disease (HD) is a neurodegenerative disorder caused by a CAG expansion within the huntingtin gene that encodes a polymorphic glutamine tract at the amino terminus of the huntingtin protein. HD is one of nine polyglutamine expansion diseases. The clinical threshold of polyglutamine expansion for HD is near 37 repeats, but the mechanism of this pathogenic length is poorly understood. U...
introduction: diarrheal diseases are a serious health problem and important causes of growth retardation and death in the developing world, especially those of prolonged duration. since diarrhea is constantly found in children with zinc deficiency, very studies supported zinc supplements beneficial on the duration and severity of diarrhea among children. we review the impact of zinc effects on ...
